The value of ultrasonographic factors in predicting cesarean following induction

This study aimed to develop and validate a prediction model of cesarean following induction of labor (IOL). A nomogram for the prediction of cesarean following IOL for singleton, cephalic term deliveries was created by comparing combinations of ultrasonographic and nonultrasonographic factors in a retrospective manner using patient data collected from a Chinese hospital between July, 2017 and December, 2023. Model discrimination and calibration were evaluated using the area under the receiver operating characteristic curve (AUROC) and a calibration curve. Subsequently, decision curve analysis (DCA) was conducted to pinpoint the optimal probability threshold for the predictive model to exhibit practical significance for clinical decision-making. A total of 738 women were included. The inclusion of ultrasound factors yielded a higher AUC when combined with nonultrasonographic factors. Of the three ultrasonographic factors analyzed, the most predictive factor for cesarean following IOL was fetal head circumference. After generating a nomogram with eight validated factors, including maternal age, gestational age, height, prior caesarean delivery, previous vaginal delivery, modified Bishop score, body mass index at delivery, and fetal head circumference by ultrasound, the trained and validated AUC values were 0.826 (95% confidence interval 0.786–0.867) and 0.883 (95% confidence interval 0.839–0.926), respectively. Decision curve analysis indicated that the model provided net benefits of between 0% and 80% of the probability threshold, indicating the benefits of using the model to make decisions concerning patients who fall within the identified range of the probability threshold. Our nomogram based on obstetric factors and fetal head circumference as obtained by ultrasound could be used to help counsel women who are considering IOL. The model demonstrates favorable net benefits within a probability threshold range of 0 to 80%.

Determinants of Success and Complications in Vaginal Birth After Cesarean Section: A Systematic Literature Review

Trial of Labor After Cesarean (TOLAC) is the process of attempting a vaginal delivery after a prior cesarean section. TOLAC offers an alternative to repeat cesarean delivery but requires careful assessment of risks and benefits. This research aims to evaluate the factors affecting VBAC success and associated risks, providing guidance for clinical practice in determining VBAC eligibility. Relevant literature on VBAC was sourced from databases such as PubMed and Cochrane Library using the keywords "VBAC," "VBAC success," and "VBAC risks." Literature searches for these articles are conducted through databases of scientific journals such as PubMed and Google Scholar. Analysis was conducted to assess predictive factors for VBAC success, including previous vaginal delivery history, cervical conditions, and other parameters. VBAC success is significantly influenced by previous vaginal delivery history, cervical conditions at admission, and factors such as BMI and interpregnancy interval. The main risk associated with VBAC is uterine rupture, occurring in approximately 0.2–0.9% of cases. Proper management and careful risk assessment can minimize complications. VBAC can be a safe and effective option for women who meet specific criteria. Adequate monitoring and assessment are crucial to minimize risks and enhance success rates. Individual evaluation and thorough planning are essential for achieving optimal delivery outcomes. The decision to implement VBAC should be made with careful consideration of the benefits and risks to ensure safe and optimal outcomes for both mother and baby.

Trial of labor after caesarean section in low risk pregnancies: is it risky?

To evaluate the influence of a previous caesarean section on adverse composite maternal and perinatal outcome in women who attempted a trial of labor. This historical cohort study analyzed maternal and perinatal outcome in women with otherwise low risk pregnancies at term who underwent a trial of labor after a caesarean section (TOLAC). The primary outcome measure was the adverse composite outcome. Secondary outcome measures were amongst others the caesarean section rate and the mode of vaginal delivery. The adverse composite outcome was more frequently in the previous caesarean section group compared to women with no previous caesarean Sect.(22.3% vs. 15.6%, p < 0.0001). The percentage of caesarean Sect.(15.4% vs. 8.2%, p < 0,0001), uterine rupture (1.0% vs. 0.02%, p < 0.0001), placental abruption (1.1% vs. 0.3%, p = 0.0014), vaginal operative delivery (16.0% vs. 8.6%, p < 0.0001), pH < 7.10 (3.7% vs. 2.5%, p = 0.0151), base excess < -12 (3.2% vs. 2.2%, p = 0.0297), abnormal cardiotocography (22.5% vs. 13.9%, p < 0,0001) and fetal blood analysis (6.2% vs. 2.6%, p < 0.0001) was significantly higher in women with a previous caesarean section. Taking the parity into account, these differences could only been seen in women without a previous vaginal delivery. In parous women with a previous vaginal delivery and a caesarean section in history, the adverse composite did not differ between the groups. Only the rate of pH < 7.1 was higher in women after a caesarean Sect.(4.5% vs. 1.8%, p = 0.0436). Trial of labor after caesarean in otherwise low risk pregnancies is associated with a higher rate of complications especially if there is no history of vaginal delivery.

Risk factors for complications following sacral neuromodulation for faecal incontinence: Long-term follow-up.

Sacral neuromodulation (SNM) has become a standard surgical treatment for faecal incontinence (FI). Prior studies have reported various adverse events of SNM, including suboptimal therapeutic response, infection, pain, haematoma, and potential need for redo SNM. The aim of this study was to identify the risk factors associated with long-term complications of SNM. This retrospective cohort reviewed patients who underwent two-stage SNM for FI at our institution between 2011-2021. Preoperative baseline characteristics and follow-up were obtained from the medical record and/or by telephone interview. Management and outcome of each postoperative event were evaluated by univariate and multivariate regression analyses. A total of 291 patients (85.2% female) were included in this study. Postoperative complications were recorded in 219 (75.2%) patients and 154 (52.9%) patients required surgical intervention to treat complications. The most common postoperative event was loss of efficacy (46.4%). Other common adverse events were problems at the implant site (pain, infection, etc.) in 16.5% and pain during stimulation in 11.7%. Previous vaginal delivery (OR 2.74, p = 0.003) and anal surgery (OR = 2.46, p = 0.039) were independent predictors for complications. Previous colorectal (OR = 2.04, p = 0.026) and anal (OR = 1.98, p = 0.022) surgery and history of irritable bowel syndrome (IBS) (OR = 3.49, p = 0.003) were independent predictors for loss of efficacy. Postoperative adverse events are frequently recorded after SNM. Loss of efficacy is the most common. Previous colorectal or anal surgery, vaginal delivery, and IBS are independent risk factors for complications.

Frequency of episiotomy practice in an institution in Quito, Ecuador 2009-2022

To determine the prevalence of episiotomy over a 14-year period and to explore its association with maternal, delivery, and neonatal variables using administrative data. This is a cross-sectional study. Women who had a vaginal delivery with a live newborn at a referral hospital for obstetric care in Ecuador were included. Consecutive sampling was employed. ICD-10 records and the perinatal information system (PIS) were utilized. Sociodemographic, gestational, delivery, and neonatal variables were assessed. Descriptive analysis was performed. The overall and yearly prevalence was determined. Exploratory bivariate and multivariate analyses were conducted. The study was approved by the Human Research Ethics Committee of the Universidad Central del Ecuador. A total of 11,862 records were analyzed. The overall prevalence of episiotomy was 36.69 %, with a maximum of 42 % and a minimum of 28 %. There is an implied trend towards a reduction in frequency from 2019 to 2022. A positive association was found between episiotomy and maternal age under 20 years, previous cesarean section, absence of a companion during delivery, term newborns, and large for gestational age newborns. A negative association was found with previous vaginal deliveries. The prevalence of episiotomy exceeds the recommendation of the World Health Organization (WHO). Clinical practice guidelines should consider potentially modifiable maternal and neonatal factors in their recommendations. Prospective studies should be conducted to evaluate the safety of the procedure, confirm these observations, and use robust methodologies to assess if there is a real decrease in its practice.

Duration of double balloon catheter for patients with prior cesarean: a before and after study

BackgroundPrevious studies that suggest a shorter time from cervical ripening balloon placement to delivery with shorter total balloon placement time have excluded patients with prior cesarean deliveries. ObjectiveTo evaluate, in patients with a prior history of cesarean delivery undergoing cervical ripening with a double-balloon catheter, whether planned removal of device after 6 vs 12 hours would result in shorter time to vaginal delivery. Study DesignA before-and-after study was performed after a practice change occurred November 2020, shortening the planned time of double-balloon catheter placement for cervical ripening from 12 to 6 hours. Data were collected via retrospective electronic chart review. Primary outcome was time from balloon placement to vaginal delivery. Secondary outcomes included rates of cesarean delivery, maternal intraamniotic infection, and uterine rupture. Kaplan–Meier curves compared median times to delivery between the groups. A Cox proportional-hazards model was used to adjust for time of balloon placement, number of previous vaginal deliveries, and co-medications used. ResultsFrom November 2018 to November 2022, 189 analyzable patients with a prior history of cesarean delivery received a double-balloon catheter for cervical ripening during their trial of labor. Patients were separated into pre- and postpolicy change groups (n=91 and 98, respectively). The median time to vaginal delivery for the pregroup was 28 hours (95% CI: 26, 35) and 25 hours (95% CI: 23, 29) for those in the postgroup (P value .052). After adjusting for dilation at time of balloon placement, number of previous vaginal deliveries, and co-medication, the estimated hazard ratio for successful vaginal delivery postpolicy change was 1.89 (95% CI: 1.27, 2.81). There were no differences in rates of secondary outcomes. ConclusionIn patients with prior cesarean delivery undergoing mechanical cervical ripening with a double-balloon catheter, planned removal at 6 hours compared to 12 hours may result in higher chances of successful vaginal delivery and possibly a shorter time to delivery, without increasing rates of cesarean delivery and intraamniotic infection.

Exploring uterine contractility frequency in infertile population: A comparative study among different control groups with and without a C-section defect.

Women undergoing IVF who have had a previous c-section (CS) have a lower live birth rate than those with a previous vaginal delivery. However, the precise underlying mechanisms need clarification. Does a previous CS affect the pattern of uterine contractility?. Prospective evaluation in patients undergoing frozen blastocyst embryo transfer in medicated endometrial preparation cycles. Twenty patients were included in groups: A/nulliparous. B/previous vaginal delivery. C/ previous CS without a niche, whereas fifteen patients were recruited in group D (CS and a niche). Patients employed estradiol compounds and 800 mg vaginal progesterone. A 3D-scan was performed the transfer-day where uterine contractility/minute was recorded. Baseline characteristics (age, BMI, smoking, endometrial thickness) were similar. Mean frequency of uterine contractions/minute was similar between groups (1.15, 1.01, 0.92, and 1.21 for groups A, B, C, and D, respectively). There was a slight increase in the number of contractions in patients with a sonographic niche versus controls, not reaching statistical significance (p=0.48). No differences were observed when comparing patients with a previous C-section (regardless of the presence of a niche) to those without a C-section, either nulliparous (p=0.78) or with a previous vaginal delivery (p=0.80). The frequency of uterine contractions was similar between patients who achieved a clinical pregnancy and those who did not (1.19 vs. 1.02 UC/min, p=0.219, respectively). Our study found no significant difference in the frequency of uterine contractility between patients with or without a previous C-section or sonographic diagnosed niche. Further investigation is necessary to understand the physiological mechanisms affecting implantation in patients with isthmocele.

Effects of epidural analgesia at 1 cm cervical dilatation on multiparae: A retrospective cohort study using propensity score-matching.

The aim of the present study was to investigate the effects of epidural analgesia (EA) administered at cervical dilatation of 1 cm on multiparae who underwent vaginal delivery. This propensity score-matched retrospective cohort research was conducted between 2021 and 2022. All the singleton multiparae who had previous successful vaginal deliveries and epidural analgesia during this delivery were screened for eligibility. The primary outcome was the effect of EA on the duration of labor. The main secondary outcomes included the incidence of cesarean delivery and umbilical arterial pH. This study incorporated 686 multiparae who were divided into two cohorts: EA 1 (cervical dilatation = 1 cm, n = 166) and EA 2 (cervical dilatation >1 cm, n = 520). In the propensity score-matched cohort (including 164 women in each group), there were no statistically significant differences in the incidence of cesarean delivery (4 [2.4%] vs 4 [2.4%], P = 1.000), umbilical arterial pH (7.28 ± 0.06 vs 7.28 ± 0.07, P = 0.550) and other secondary outcomes between the two groups. Based on a comparative assessment of the women who delivered vaginally to the Kaplan-Meier curves and propensity score-matching (including 160 women in each group), there was no statistical significance in the duration of the first, second and third stages of labor (log rank P, P = 0.811; P = 0.413; P = 0.773, respectively). Initiation of epidural analgesia at cervical dilatation of 1 cm in multiparae did not cause adverse effects with regard to the duration of labor, increased cesarean deliveries, and bad neonatal outcomes.

Short stature and vaginal dinoprostone as independent predictors of composite maternal-newborn adverse outcomes in induction of labor after one previous cesarean: a retrospective cohort study

BackgroundThe rates of labor induction and cesarean delivery is rising worldwide. With the confluence of these trends, the labor induction rate in trials of labor after cesarean can be as high as 27-32.7%. Induction of labor after one previous cesarean (IOLAC) is a high-risk procedure mainly due to the higher risk of uterine rupture. Nevertheless, the American College of Obstetricians and Gynecologists considers IOLAC as an option in motivated and informed women in the appropriate care setting. We sought to identify predictors of a composite of maternal and newborn adverse outcomes following IOLAC.MethodsThe electronic medical records of women who delivered between January 2018 to September 2022 in a Malaysian university hospital were screened to identify cases of IOLAC. A case is classified as a composite adverse outcome if at least one of these 11 adverse outcomes of delivery blood loss ≥ 1000 ml, uterine scar complications, cord prolapse or presentation, placenta abruption, maternal fever (≥ 38 0C), chorioamnionitis, intensive care unit (ICU) admission, Apgar score < 7 at 5 min, umbilical artery cord artery blood pH < 7.1 or base excess ≤-12 mmol/l, and neonatal ICU admission was present. An unplanned cesarean delivery was not considered an adverse outcome as the practical management alternative for a clinically indicated IOLAC was a planned cesarean. Bivariate analysis of participants’ characteristics was performed to identify predictors of their association with composite adverse outcome. Characteristics with crude p < 0.10 on bivariate analysis were incorporated into a multivariable binary logistic regression analysis model.ResultsElectronic medical records of 19,064 women were screened. 819 IOLAC cases and 98 cases with composite adverse outcomes were identified. Maternal height, ethnicity, previous vaginal delivery, indication of previous cesarean, indication for IOLAC, and method of IOLAC had p < 0.10 on bivariate analysis and were incorporated into a multivariable binary logistic regression analysis. After adjustment, only maternal height and IOLAC by vaginal dinoprostone compared to Foley balloon remained significant at p < 0.05. Post hoc adjusted analysis that included all unplanned cesarean as an added qualifier for composite adverse outcome showed higher body mass index, short stature (< 157 cm), not of Chinese ethnicity, no prior vaginal delivery, prior cesarean indicated by labor dystocia, and less favorable Bishop score (< 6) were independent predictors of the expanded composite adverse outcome.ConclusionShorter women and IOLAC by vaginal dinoprostone compared to Foley balloon were independently predictive of composite of adverse outcome.

The Development and Evaluation of Alternative Communication Strategies to Facilitate Interactions with Refugees in Obstetric Triage: A Preliminary Study

Purpose: In this pilot study, we investigate the potential of pictographs to facilitate communication and accelerate care for non-English speaking birthing people in triage. The immigrant and refugee populations have been steadily increasing in the United States; reproductive age women are a large percentage of those who seek medical care. Barriers to care include timely access to interpreters, which can delay treatment. Pictographs have been used successfully in medicine in various situations such as pharmaceutical instruction and symptom description. We searched extensively for obstetric triage pictographs with little success. To address this, we created a pictograph sheet specifically for common obstetrical complaints. Methods: The most common reasons for visiting triage were ascertained. From these, key topics were identified for drawings. For each topic, the authors drafted scripts for a list of relevant actions. The actions for each topic were then represented by a professional illustrator in pictographs. Pictographs were developed using the following guidelines: focus on actions people should take, include prompts within pictures such as labels or arrows and exclude nonessential details such as room background and elaborate borders. After the pictographs were developed, its appropriateness, accuracy and relevance were reviewed and validated by two experts with experience in women’ care. The experts perceived that the drawings represented the actions well in a simple and clean manner. The following concerns were depicted: decreased fetal movement, abnormal vaginal discharge, rupture of membranes, vaginal bleeding, vision changes, shortness of breath, nausea, contractions, headaches, and overall assessment of wellbeing. Focus groups were developed collaboratively with Della Lamb, a resettlement agency. Inclusion criteria included women of reproductive age who are non-English speaking and currently pregnant. These focus groups were held at the University Health. Two focus groups were created: one with refugees from Afghanistan and one with refugees from the Congo. Each focus group was guided by a licensed medical interpreter of their native language: Dari and Swahili, respectively, and ranged from 3 to 4 participants. One by one the pictograms were introduced to the group. Each participant was asked what they think the illustration represents. For participants’ comfort, groups were not recorded; instead, notes were taken by observers during and after the discussion. The participants read the text and pictographs and were asked to identify if pictographs were clear, understandable, and acceptable. Results: Congolese Focus Group: Participants’ ages varied in their 30s. All had recently immigrated to the United States and lived in Missouri for less than 6 months. They were in the second trimester of their pregnancy and had at least one prenatal visit in the United States. They were all multiparous women with previous uncomplicated vaginal deliveries in their native country. All could read and write in Swahili but spoke no English. They all had no previous experience with the medical health system in the United States. Afghani Focus Group: Participants’ ages varied in their 20-30s. All had recently immigrated to the United States and lived in Missouri for less than 3 months. 3 women were in their second trimester, 1 was in her third trimester. Aside from 1, the rest (3) were multiparous women with previous uncomplicated vaginal deliveries in their native country. 3 of them could read and write in Dari but spoke no English. They all had no previous experience with the medical health system in the United States. Comprehension was significantly different between the two groups. Overall, the Congolese group of women misunderstood the purpose of the pictographs. No picture was understandable to the patients. It was also apparent that the patients did not realize these were issues for which to come to triage. There was also ambiguity regarding the color, i.e. they did not correlate green with nausea. The general prohibition sign was also absent in meaning for them. However, all of the patients expressed interest in learning what each picture meant and would like to have that option there if they came to triage and could not get an interpreter. The Dari group did not understand shortness of breath or nausea. However, they were familiar with the other symptoms and able to identify those as reasons to come to triage. The patients were also familiar with colors and scales. Conclusion: The pictograph-based approach might be an effective tool in developing health-care instructions for immigrant women with limited literacy skills. However, research is needed regarding limitations due to cultural backgrounds. Future research is also needed to compare the effect of pictograph-enhanced instructions with written text-based instructions on adherence to instructions and health outcomes.

Patient Decision Making Surrounding Epidural Use in Labor

Introduction/Objectives: Labor is thought to be one of the most painful experiences in a woman’s life, similar to pain caused by complex regional pain syndromes. Epidural analgesia has been proven to provide excellent pain relief, and many women in the United States choose this during their labor course. The decision to use, or not to use, neuraxial analgesia is complex and multifactorial, and has historically generated debate amongst patients and obstetric providers. In addition, many patients will also change their minds about desiring an epidural in labor during their admission to Labor &amp; Delivery based on various factors encountered. This study aimed to determine the number of patients who change their mind about epidural in labor. We also aimed to characterize the factors involved in patients’ decision about epidural analgesia during labor and to determine if these factors change throughout the labor and delivery course. Methods: This study was a single-center, non-randomized, cross-sectional study that was performed at Loyola University Medical Center in the Labor &amp; Delivery unit. The study population included all full-term nulliparous patients that were admitted to Labor &amp; Delivery for full term labor or induction of labor. Patients were eligible if they were 18 years of age or older, and able to read, speak, and complete the study questionnaire in English. Exclusion criteria included previous vaginal delivery, contraindication to vaginal delivery, no plan to deliver during admission, and contraindication to epidural analgesia. The patients completed one questionnaire about preferences for epidural and influencing factors prior to delivery, and one questionnaire after delivery with similar questions. Demographics were collected, as well as data about complications and details of their labor and delivery course. Results: A total of 199 patients completed the study. The epidural rate was higher in patients who planned to receive it (n = 141/144 or 97.9%) than in patients who did not plan to receive an epidural (n = 49/55 or 89.1%). Further, there was significant discordance between patients’ plans for an epidural and receipt of the medication. That is, only three (1.5%) patients who planned to receive an epidural did not receive one. Conversely, 49 (24.6%) patients who did not plan to receive an epidural received one. Compared to patients who did not plan to receive an epidural, those who planned to receive the medication reported that their OBGYN physician (OR = 3.31, 95% CI: 1.80 – 6.06; p &lt; .001), Anesthesiology physician (OR = 2.73, 95% CI: 1.50 – 4.96; p = .001), and labor nurse (OR = 2.50, 95% CI: 1.38 – 4.53; p =.002) were more important sources of information. Further, when compared to patients who did not plan to receive an epidural, those who planned to receive the medication reported they wanted to be more comfortable during the course of labor (OR = 4.84, 95% CI: 2.50 – 9.39; p &lt; .001), that receiving an epidural would make their labor experience more enjoyable (OR = 27.17, 95% CI: 11.72 – 63.00; p &lt; .001), and that getting an epidural was safe (OR = 5.91, 95% CI: 2.96 – 11.80; p &lt; .001). Conclusions: In conclusion, this study found that the majority of patients in our study population chose to receive an epidural in labor, regardless of their plans at the start of their admission. The most important factors in the decision were discussions with the OBGYN and Anesthesiology physicians. Patients who decided to receive an epidural, despite planning not to, reported that they wanted to be more comfortable during their labor course and that receiving an epidural would make their labor experience more enjoyable.

Trial of Labor versus Repeat Cesarean Delivery in Individuals with Morbid Obesity after Previous Cesarean Delivery.

This study aimed to compare adverse neonatal outcomes associated with the trial of labor after cesarean (TOLAC) at term in pregnancies according to maternal prepregnancy body mass index (BMI; kg/m2) and the presence of previous vaginal delivery (VD). This was a repeated cross-sectional analysis of individuals with singleton, cephalic, and term deliveries with a history of one or two cesarean deliveries in the Linked Birth/Infant Death data from 2011 to 2020. Outcomes were examined according to the BMI category including BMI <30, 30 to 39.9, and 40 to 69.9 kg/m2. The primary outcome was a composite neonatal outcome, defined as any presence of neonatal death, neonatal intensive care unit admission, assisted ventilation, surfactant therapy, or seizures. Outcomes were compared between TOLAC and elective repeat cesarean delivery (eRCD) after stratifying by BMI category and previous VD. Log-binomial regression was performed to obtain adjusted relative risk (aRR) with 99% confidence intervals, controlling for covariates. Of 4,055,440 individuals, 2,627,131 had BMI <30 kg/m2, 1,108,278 had BMI 30 to 39.9 kg/m2, and 320,031 had BMI 40 to 69.9 kg/m2. In individuals with no previous VD, VD rates after TOLAC were 66.7, 57.2, and 48.1%, respectively. In individuals with previous VD, VD rates after TOLAC were 81.4, 74.7, and 67.3%, respectively. In individuals without previous VD, compared with those who had an eRCD, those who had TOLAC were more likely to experience composite neonatal outcomes in individuals with BMI < 30 kg/m2 (5.0 vs. 6.5%; aRR = 1.33 [1.30-1.36]), BMI 30 to 39.9 kg/m2 (6.1 vs. 7.8%; aRR = 1.29 [1.24-1.34]), and BMI 40 to 69.9 kg/m2 (8.2 vs. 9.0%; aRR = 1.15 [1.07-1.23]). In individuals with previous VD, there was no difference in the composite neonatal outcomes in BMI < 30 kg/m2 (6.2 vs. 5.8%; aRR = 0.98 [0.96-1.00]), BMI 30 to 39.9 kg/m2 (7.4 vs. 7.1%; aRR = 0.99 [0.95-1.02]), and BMI 40 to 69.9 kg/m2 (9.4 vs. 8.7%; aRR = 0.96 [0.91-1.02]). TOLAC among obese individuals could be offered in selected cases. · TOLAC among obese individuals could be offered selectively, despite their reduced likelihood of attempting or succeeding at it.. · Higher BMI individuals show decreased rates of both attempting and achieving successful TOLAC.. · Despite these trends, attempting TOLAC after a previous vaginal delivery does not heighten neonatal complications..

Differing Approaches to Pain Management for Intrauterine Device Insertion and Maintenance: A Scoping Review.

Intrauterine devices (IUDs) are considered a reliable contraceptive option for women,but they can come with side effects. There is a disconnect in standard guidelines for IUD insertion within and without the U.S. The objective of this review was to address a gap in the literature regarding official procedures for pain management during IUD implantation.This scoping review was initiated using keywords to extract relevant articles from multiple databases: U.S. National Library of Medicine National Institutes of Health (PubMed), MEDLINE (Ovid), and Excerpta Medica dataBASE (EMBASE, Ovid). Initially, 457 articles were identified and after a rigorous screening and selection process, 37 articles were chosen to be further assessed to ascertain if they met the study's inclusion criteria. Those 37 articles were further evaluated fully to check for relevancy. From that process, 19 articles were chosen for the review, and all passed quality assessment evaluations using the JB Appraisal Tools. To best address the research question, the data from the 19 articles were divided into three categories: 1) circumstantial factors, 2) non-pharmacological methods, and 3) pharmacological methods. Circumstantially, women with previous vaginal deliveries experienced the lowest pain during the procedure, and nulligravid (never pregnant) women experienced the most pain. Lower pain scores were reported by lactating women compared to non-lactating. Black women experienced the most anticipated pain compared to other races. Regarding non-pharmacological methods, different insertion techniques, tools, and the use of a cold compress were found to not affect the level of pain during IUD insertion. Lastly, it was shown that pharmacological methods such as lidocaine gel, lidocaine paracervical block, and lidocaine combined with either diclofenac or prilocaine decreased pain scores at different time stamps of the procedure. Also, oral ketorolac and a vaginal combination of misoprostol and dinoprostone helped reduce pain.Findings from this scoping review revealed a lack of uniformity across practices when performing IUD insertions, possibly due to differences in procedures across circumstantial factors, non-pharmacological methods, and pharmacological methods. More research is needed to investigate the intricacies of pain with IUD insertion. Moving forward, especially following a potential increase in the use of IUDs after the reversal of Roe v. Wade, establishing this gap may lead to a more refined standardized protocol to mitigate pain with IUD insertions.

The association between unintended hysterotomy extensions with cesarean delivery and subsequent preterm birth

BackgroundAn increased risk of preterm birth has been observed among individuals with a previous second stage cesarean delivery compared with a previous vaginal delivery. One mechanism that may contribute to the increased risk of preterm birth following second stage cesarean delivery is the increased risk of cervical injury due to extension of the uterine incision (hysterotomy) into the cervix. Investigating the contribution of hysterotomy extension to the rate of preterm birth has not been well-studied and may shed light on the mechanisms underlying the observed relationship between mode of delivery and subsequent preterm birth. ObjectiveWe aimed to quantify the association between unintended hysterotomy extension and preterm birth in a subsequent delivery. Study designWe performed a retrospective cohort study using electronic perinatal data collected in two university-affiliated obstetrical centers. The study included patients with a primary cesarean delivery of a term, singleton live birth and a subsequent singleton birth in the same catchment (2005-2021). The primary outcome was subsequent preterm birth <37 weeks; secondary outcomes included subsequent preterm birth <34, <32 and <28 weeks. We assessed crude and adjusted associations between unintended hysterotomy extensions and subsequent preterm birth with log binomial regression models using rate ratios (RRs) and 95% confidence intervals (CIs). Adjusted models included several characteristics of the primary cesarean delivery such as maternal age, length of active labour, indication for cesarean delivery, chorioamnionitis, and maternal comorbidity. ResultsA total 4,797 patients met the study inclusion criteria. The overall rate of unintended hysterotomy extension in the primary cesarean delivery was 6.0% and the total rate of preterm birth in the subsequent pregnancy was 4.8%. Patients with an unintended hysterotomy extension were more likely to have a longer duration of active labour, chorioamnionitis, failed vacuum delivery attempt, second stage cesarean delivery, and persistent occiput posterior position of the fetal head in the primary cesarean delivery and higher rates of smoking in the subsequent pregnancy. Multivariable analyses controlling for several confounders showed that a history of hysterotomy extension is not associated with a higher risk of preterm birth <37 weeks gestation (adjusted RR 1.55, 95% CI 0.98-2.47), but is associated with preterm birth <34 weeks gestation (adjusted RR 2.49, 95% CI 1.06-5.42). ConclusionPatients with a uterine incision extension have a 2.5 times higher rate of preterm birth <34 weeks compared with patients who do not sustain this injury. This association was not observed for preterm birth <37 weeks. Future research should aim to replicate our analyses while incorporating additional data to minimize the potential for residual confounding.

Trial of labor after 2 previous cesareans: a multicenter study

Trial of labor after cesarean after 2 cesarean deliveries is linked to a lower success rate of vaginal delivery and higher rates of adverse obstetrical outcomes than trial of labor after cesarean after 1 previous cesarean delivery. This study aimed to investigate the factors associated with failed trial of labor after cesarean among women with 2 previous cesarean deliveries. This was a multicenter retrospective cohort study, which included all women with singleton pregnancies attempting trial of labor after cesarean after 2 previous cesarean deliveries between 2003 and 2021. This study compared labor, maternal, and neonatal characteristics between women with failed trial of labor after cesarean and those with successful trial of labor after cesarean. Univariate analysis was initially performed, followed by multivariable analysis (adjusted odds ratios with 95% confidence intervals). The study included a total of 1181 women attempting trial of labor after cesarean after 2 previous cesarean deliveries. Among these cases, vaginal birth after cesarean was achieved in 973 women (82.4%). Women with failed trial of labor after cesarean had higher rates of maternal and neonatal morbidities. Several factors were found to be associated with failed trial of labor after cesarean, including longer interpregnancy and interdelivery intervals, lower gravidity and parity, lower rates of previous successful vaginal delivery, smoking, earlier gestational age at delivery (38.3±2.1 vs 39.5±1.3 weeks), late preterm delivery (34-37 weeks of gestation), lower cervical dilation on admission, no use of epidural, and smaller neonatal birthweight. Our multivariable model revealed that late preterm delivery (adjusted odds ratio, 3.79; 95% confidence interval, 1.37-10.47) and cervical dilation on admission for labor <3 cm (adjusted odds ratio, 2.58; 95% confidence interval, 1.47-4.54) were associated with higher odds of failed trial of labor after cesarean. In the investigated population of women with 2 previous cesarean deliveries undergoing trial of labor after cesarean, admission at the late preterm period with a cervical dilation of <3 cm, which reflects the latent phase, may elevate the risk of failed trial of labor after cesarean and a repeated intrapartum cesarean delivery.

Unplanned cesarean sections in advanced maternal age: Apredictive model.

As maternal age during pregnancy is rising all over the world, there is a growing need for prognostic factors that determine maternal and perinatal outcomes in older women. This study is a retrospective cohort study of women aged 40 years or older at the time of delivery in four Santeon hospitals across the Netherlands between January 2016 and December 2019. Outcomes were compared between women of 40-44 years (advanced maternal age) and 45 years and older (very advanced maternal age). Primary outcome was unplanned cesarean section, secondary outcomes included postpartum hemorrhage and neonatal outcomes. Multivariate regression analysis was performed to analyze predictive factors for unplanned cesarean sections in women who attempted vaginal delivery. Subsequently, a predictive model and risk scores were constructed to predict unplanned cesarean section. A cohort of 1660 women was analyzed; mean maternal age was 41.4 years, 4.8% of the women were 45 years and older. In both groups, more than half of the women had not delivered vaginally before. Unplanned cesarean sections were performed in 21.1% of the deliveries in advanced maternal age and in 29.1% in very advanced maternal age. Four predictive factors were significantly correlated with unplanned cesarean sections: higher body mass index (BMI), no previous vaginal delivery, spontaneous start of delivery and number of days needed for cervical priming. A predictive model was constructed from these factors with an area under the curve of 0.75 (95% confidence interval 0.72-0.78). A sensitivity analysis in nulliparous women proved that BMI, days of cervical priming, age, and gestational age were risk factors, whereas spontaneous start of delivery and induction were protective factors. There was one occurrence of neonatal death. Women of advanced maternal age and those of very advanced maternal age have a higher chance of having an unplanned cesarean section compared to the general obstetric population in the Netherlands. Unplanned cesarean sections can be predicted through use of our predictive model. Risk increases with higher BMI, no previous vaginal delivery, and increasing number of days needed for cervical priming, whereas spontaneous start of labor lowers the risk. In nulliparous women, age and gestational age also increase risk, but induction lowers the risk of having an unplanned cesarean section.

Effect of prior cesarean delivery on the outcomes of intracytoplasmic sperm injection.

This study was conducted to investigate the impact of previous delivery mode on pregnancy outcomes in patients with secondary infertility after frozen-thawed embryo transfer. This prospective observational study included 140 patients experiencing secondary infertility. Of these, 70 patients had a previous cesarean delivery (CD), while the remaining 70 patients had a previous normal vaginal delivery (NVD). The primary outcome was the implantation rate. The secondary outcomes included rates of clinical pregnancy, chemical pregnancy, miscarriage, and ectopic pregnancy. The comparison of all fertility outcomes between the two groups revealed no statistically significant differences. The implantation rate was 40.4% in the CD group and 41.7% in the NVD group (p=0.842). The clinical pregnancy rate was 50% in the CD group and 49.3% in the NVD group (p=0.932), while the chemical pregnancy rate was 14.6% in the CD group and 19% in the NVD group (p=0.591). The miscarriage rates in the CD and NVD groups were 20% and 17.6%, respectively (p=0.803). One case of tubal ectopic pregnancy occurred in the NVD group (1.4%). The mode of prior delivery did not significantly impact pregnancy outcomes following frozen-thawed embryo transfer.

Reproductive outcomes after in vitro fertilization in women with cesarean section scar diverticulum: A retrospective study.

Some studies have suggested that cesarean section diverticulum may affect the pregnancy outcomes of assisted reproductive technology through a variety of mechanisms. This study aims to explore whether previous cesarean section and uterine scar diverticulum affect pregnancy outcomes after in vitro fertilization. This retrospective study included 954 infertile women with only one previous delivery who had in vitro fertilization treatment and underwent fresh embryo transplantation for the first time at our center between 2015 and 2019. We first divided the women into two groups by previous vaginal delivery (n = 557) or cesarean section delivery (n = 397), and the latter group included 88 women with cesarean diverticulum and 309 women without cesarean diverticulum. Baseline characteristics were compared and analyzed, and logistic regression analyses were performed to explore the different pregnancy outcomes among the above groups. Although the live birth rate, clinical pregnancy rate, and mean embryo implantation rate after in vitro fertilization were significantly reduced in patients with previous cesarean section (live birth rate: 26.45% vs. 43.99%, adjusted OR: 0.602, CI: 0.447-0.810; clinical pregnancy rate: 35.26% vs. 49.91%, adjusted OR: 0.724, CI: 0.544-0.962; mean embryo implantation rate: 0.227 ± 0.378 vs. 0.243 ± 0.397, adjusted OR: 0.860, CI: 0.514-1.439), there were no significant differences in pregnancy outcomes between the women with cesarean diverticulum and without cesarean diverticulum (p > 0.05) or between the two groups at different ages. The live birth and clinical pregnancy rates in the women with residual muscle thickness ≤2.2 mm or prolonged menstruation were reduced, but the difference was not statistically significant (p > 0.05). This study showed reduced pregnancy and live birth rates after in vitro fertilization in patients with previous cesarean section, while uterine scarring did not adversely affect pregnancy and delivery outcomes after in vitro fertiliazation.

Study of Childbirth with A Single Scar Uterus at the "Major Moussa Diakite" Reference Health Center in Kati, Mali

The management of childbirth in a scarred uterus is one of the most debated subjects in modern obstetrics, due to the considerable increase in caesarean section rates and many other risks of complication such as disunion of the old scar. Objective: To study childbirth with a single scar uterus at the Kati Reference Health Center. Method: This was a prospective cross-sectional study, which ran from 1 January to 31 December 2021. It focused on parturients with a single myometrial scar, a vertex presentation of the foetus, a clinically normal pelvis, a uterine height of less than 36 centimeters, a single foetal pregnancy and an intergenesic interval of more than one year. Results: Out of a total of 2521 deliveries, seventy (70) women met the criteria of our study, or a frequency of 28%. The average age of parturients was 30, with extremes ranging from 18 to 42. Only 20% of our parturients had completed four antenatal consultations. They were carried out in 78.5% of cases by qualified staff. Eight out of ten of our parturients (81.4%) came on their own, and in seven out of ten cases (70.0%) in the active phase of childbirth. Delivery was by natural route in almost seven out of ten cases (65.7%), compared with caesarean section in 34.3% of cases. The indications for caesarean section were dominated by dynamic dystocia (66.7%), followed by failure to engage (12.5%), acute foetal distress (12.5%) and umbilical cord prolapse (8.3%). Previous vaginal delivery prior to caesarean section was associated with a successful uterine test (P=0.019). Maternal complications were haemorrhage due to uterine atony (1 case) and disunion of the old caesarean scar (1 case). We recorded two macerated stillbirths and one case of early neonatal death linked to extreme prematurity, and six cases of neonatal suffering. Conclusion: Childbirth in a scar uterus is a high-risk delivery, and strict adherence to the conditions under which it is carried out is essential to improve the maternal and ....
