COMPARISON OF PPH IN INDUCED WITH PROSTAGLANDIN E2 VERSUS SPONTANEOUS LABOUR

Postpartum haemorrhage (PPH) remains a significant obstetric complication, leading to maternal morbidity and mortality. The impact of labour induction on the incidence of PPH compared to spontaneous labour is crucial for guiding clinical practices. Objective: To compare the incidence of postpartum haemorrhage in patients undergoing induced labour versus those experiencing spontaneous labour. Methods: A randomized controlled trial was conducted from April to September 2024 in the Obstetrics and Gynecology Department of DHQ Teaching Hospital, Mirpur AJK. A total of 70 patients with term singleton pregnancies were included, with 35 undergoing spontaneous labour and 35 experiencing labour induction. The incidence of PPH was recorded in both groups. Informed consent was obtained from all participants, and ethical approval was granted by the hospital's ethics committee. Results: Among 35 patients with spontaneous labour, 88.57% (n=31) had normal vaginal deliveries, 11.43% (n=4) underwent cesarean sections, and 8.5% (n=3) experienced PPH. In contrast, of the 35 patients induced into labour, 77.14% (n=27) had normal vaginal deliveries, 22.85% (n=8) underwent cesarean sections, and 31.43% (n=8) experienced PPH. The incidence of PPH was significantly higher in the induced labour group compared to the spontaneous labour group. Conclusion: Labor induction is associated with an increased frequency of postpartum haemorrhage. Induction should be reserved for cases with strong medical indications, and safer methods, such as prostaglandins, should be preferred over artificial rupture of membranes to minimize risks.

The Association of Serum Fibrinogen Levels With the Severity of Primary Postpartum Hemorrhage: A Prospective Study.

Postpartum hemorrhage (PPH) remains a major cause of maternal mortality and morbidity worldwide. Coagulation disorders are a major risk factor for PPH that have not been studied adequately. Fibrinogen, a plasma glycoprotein, is integral to hemostasis and is involved in the final process of the coagulation cascade. Fibrinogen levels increase with advancing pregnancy probably because of an increase in estrogen levels and reach a peak (~5g/L) in the third trimester of pregnancy. However, in the postpartum period, the fibrinogen concentration shows a decreasing trend. The purpose of the study was to study the serum fibrinogen levelin patients with PPH and to find its association with the severity of primary postpartum hemorrhage. Methodology: Patients were selected according to inclusion and exclusion criteria. Written and informed consents were taken. Routine investigations were done on admission and special investigations like red blood cell count, prothrombin time, international normalized ratio,activated partial thromboplastin time, and serum fibrinogen were done later when the patient developed PPH. Serial samples of all PPH patients for serum fibrinogen levels at0, 1, 2, 4, and 24 hours were taken to study the serum fibrinogen levels and data were analyzed. Result: The mean fibrinogen level on admission was 3.92 ± 0.92 g/lin non-severe PPH and 2.03 ± 0.97 g/l in the severe PPH group.Fibrinogen levels in the non-severe group remained < 4.46 g/l at 0, 1, 2, 4, and 24 hours. In the severe group, fibrinogen levels were < 2.89 g/l at 0, 1, 2, and 4 hours and it was 2.44 ± 1.06g/l in the 24-hour samples. Statistical significance was found in all the fibrinogen values among the two study groups (p = 0.001). Our results showed that zero-hour fibrinogen levels correlate significantly with the aggravation of PPH and levels <2 g/L can serve as a predictor for progression to severe PPH.

Nomogram based on clinical characteristics and ultrasound indicators for predicting severe postpartum hemorrhage in patients with anterior placenta previa combined with previous cesarean section: a retrospective case-control study

BackgroundPlacental accreta spectrum disorders (PAS) are a high-risk group for severe postpartum hemorrhage (SPPH), with the incidence of PAS increasing annually. Given that cesarean section and anterior placenta previa are the primary risk factors for PAS, therefore, our study aims to investigate the predictive value of clinical characteristics and ultrasound indicators for SPPH in patients with anterior placenta previa combined with previous cesarean section, providing a theoretical basis for early prediction of SPPH.MethodsA total of 450 patients with anterior placenta previa combined with previous cesarean section were retrospectively analyzed at Shengjing Hospital affiliated with China Medical University between January 2018 and March 2022. Clinical data and ultrasound indicators were collected. Patients were categorized into SPPH (blood loss >2000mL, 182 cases) and non-SPPH (blood loss ≤ 2000mL, 268 cases) groups based on the blood loss within 24 h postpartum. The population was randomly divided into training and validation cohorts at a 7:3 ratio. LASSO and multifactorial logistic regression analyses were utilized to identify independent risk factors for SPPH. Accordingly, a nomogram prediction model was constructed, the predictive performance was assessed using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA).ResultsAmong the 450 patients, 182 experienced SPPH (incidence rate, 40.44%). Preoperative systemic immune-inflammatory index, preoperative D-dimer level, preoperative placenta accreta spectrum ultrasound scoring system (PASUSS) score, and one-step-conservative surgery were identified as independent risk factors for SPPH in patients with anterior placenta previa combined with previous cesarean section. A nomogram was constructed based on these factors. The areas under the ROC curves for the training and validation cohorts were 0.844 (95%CI: 0.801–0.888) and 0.863 (95%CI: 0.803–0.923), respectively. Calibration curves and DCA indicated that this nomogram demonstrated good predictive accuracy.ConclusionsThis nomogram presents an effective and convenient prediction model for identifying SPPH in patients with anterior placenta previa combined with previous cesarean section. It can guide surgical planning and improve prognosis.

Comparison of Carbetocin and Oxytocin Efficacy in Preventing Postpartum Hemorrhage after C-Section

Introduction: Postpartum hemorrhage (PPH) is defined as a blood loss of more than 0.5 liters within 24 hours of birth, and a blood loss of more than 1 liter is considered a significant PPH. In low- and middle-income countries, PPH is a major factor causing maternal morbidity and mortality, whereas in high-income countries, the mortality is comparatively lower, but still PPH poses a major risk for postpregnancy complications. Uterine atony is the most frequent cause of the PPH, and it accounts for up to 80% of PPH cases. Aim: The aim of this study is to examine the prophylactic effects of oxytocin and carbetocin in preventing atonic PPH in individuals receiving recurrent elective CS under spinal anesthesia. Materials and Methods: A computerized, randomized, cross-sectional prospective comparative study was conducted on 100 pregnant women at Konaseema Institute of Medical Sciences and Research Foundation for the time period of an year, from October 2020 to October 2021. Inclusion Criteria: This study includes patients with singleton pregnancy, gestational age &gt;38 weeks, spinal anesthesia and repeated C.S with cephalic, breech, or any malpresentations. Exclusion Criteria: Patients with placenta previa and placental abruption, uterine myomata, congenital uterine anomalies, gestational age before 38 weeks, women having emergency cesarean section for fetal or maternal distress, and patients with hepatic or pre-existing bleeding disorder were excluded from the study. The patients included based on the above criteria were split into two equal groups. Group I received carbetocin as a single dose of 100 microgram slow intravenous, and Group II received oxytocin as 5 IU intravenous drip followed by 20 IU of oxytocin infusion on 500 ml saline or lactated ringer with a rate of 150 ml per hour. Results: When compared to the oxytocin group, the blood loss was considerably reduced in the carbetocin group. The levels of Hb and hematocrit [HCT] were evaluated pre- and postoperative in both the groups. The levels of preoperative Hb and HCT showed nonsignificant difference between the two groups, while the levels of postoperative Hb and HCT were significantly higher in carbetocin group than oxytocin group concluding that carbetocin showed the better results in controlling the blood loss and maintaining the levels of Hb and HCT volume and the carbetocin group showed less need for administration of uterotonic agents (20%) in comparison with (32%) in oxytocin group but with no statistically significant difference. Only 8 (16%) patients showed PPH in carbetocin treatment, whereas 14 (28%) showed PPH in patients on oxytocin treatment.

Risk factors for postpartum hemorrhage according to the Robson classification in a low-risk maternity hospital.

To evaluate the risk factors for postpartum hemorrhage (PPH) according to the Robson Classification in a low-risk maternity hospital. We conducted retrospective cohort study by analyzing the medical records of pregnant women attended in a low-risk maternity hospital, during from November 2019 to November 2021. Variables analyzed were: maternal age, type of delivery, birth weight, parity, Robson Classification, and causes of PPH. We compared the occurrence of PPH between pregnant women with spontaneous (Groups 1 and 3) and with induction of labor (2a and 4a). Chi-square and Student t-tests were performed. Variables were compared using binary logistic regression. There were 11,935 deliveries during the study period. According to Robson's Classification, 48.2% were classified as 1 and 3 (Group I: 5,750/11,935) and 26.1% as 2a and 4a (Group II: 3,124/11,935). Group II had higher prevalence of PPH than Group I (3.5 vs. 2.7%, p=0.028). Labor induction increased the occurrence of PPH by 18.8% (RR: 1.188, 95% CI: 1.02-1.36, p=0.030). Model including forceps delivery [x2(3)=10.6, OR: 7.26, 95%CI: 3.32-15.84, R2 Nagelkerke: 0.011, p<0.001] and birth weight [x2(4)=59.0, OR: 1.001, 95%CI:1.001-1.001, R2 Nagelkerke: 0.033, p<0.001] was the best for predicting PPH in patients classified as Robson 1, 3, 2a, and 4a. Birth weight was poor predictor of PPH (area under ROC curve: 0.612, p<0.001, 95%CI: 0.572-0.653). Robson Classification 2a and 4a showed the highest rates of postpartum hemorrhage. The model including forceps delivery and birth weight was the best predictor for postpartum hemorrhage in Robson Classification 1, 3, 2a, and 4a.

Uterine necrosis following uterine artery embolization as treatment for postpartum hemorrhage: A case report and literature review.

Uterine necrosis is a rare complication of uterine artery embolization for postpartum hemorrhage and most patients end up having a hysterectomy. Here we report a case in which the patient experienced a recurrent fever 28 days after uterine artery embolization as treatment for postpartum hemorrhage and had no response to antibiotics. Magnetic resonance imaging of the pelvis revealed a mass which was approximately 12-cm in size with air bubbles in the uterus, suggesting necrosis with infection. Transvaginal clamping of the uterine mass was performed and necrotic tissue removed under laparoscopic monitoring, which successfully spared the necessity for a hysterectomy. The patient's subsequent progress was favorable. In the present study we review the high-risk factors of uterine necrosis following uterine artery embolization and summarize the key points of early diagnosis. In addition, we propose a strategy to successfully spare the necessity for a hysterectomy without the spread of infection or uterine perforation.

Perioperative outcomes and causes of postpartum hemorrhage in patients undergoing cesarean delivery in Thailand: A comprehensive retrospective study.

This study aimed to identify the characteristics, causes, perioperative anesthetic, and obstetric outcomes of patients experiencing postpartum hemorrhage (PPH) after cesarean delivery. We retrospectively analyzed patients who underwent cesarean delivery at the largest university hospital in Bangkok, Thailand, during a 5-year period (January 1, 2016-December 31, 2020). PPH was defined as an estimated blood loss (EBL) of ≥ 1000 ml within 24 hours postpartum. Of 17 187 cesarean deliveries during the study period, 649 patients were included for analysis. The mean EBL was 1774.3 ± 1564.4 ml (range: 1000-26 000 ml). Among the patients, 166 (25.6%) experienced massive PPH (blood loss > 2000 ml). Intraoperative blood transfusions were necessary for 264 patients (40.7%), while 504 individuals (77.7%) needed intraoperative vasopressors. The analysis revealed uterine atony as the leading cause of PPH in 62.7% (n = 407) of the patients, with abnormal placentation following at 29.3% (n = 190). Abnormal placentation was associated with a significantly higher mean EBL of 2345.0 ± 2303.9 ml compared to uterine atony, which had a mean EBL of 1504.0 ± 820.7 ml (P < 0.001). Abnormal placentation also significantly increased the likelihood of blood transfusions and hysterectomies (P < 0.001 for both) and led to more intensive care unit admissions (P = 0.032). The risk of EBL exceeding 2000 ml was markedly higher in patients with abnormal placentation (odds ratio [OR] 5.12, 95% confidence interval [CI] 3.45-7.57, P < 0.001) and in cases involving trauma to the internal organs (OR 2.33, 95% CI 1.16-4.71, P = 0.018) than in patients with uterine atony. The study documented three instances of perioperative cardiac arrest, one of which was fatal. These findings highlight the importance of comprehensive perioperative management strategies, including the ready availability of adequate blood and blood products, particularly in scenarios predisposed to significant hemorrhage. Clinical trial registration: Clinicaltrial.gov registration number NCT04833556 (April 6, 2021).

Safety and efficacy of pelvic arterial embolization for primary postpartum hemorrhage in hemodynamically stable and hemodynamically unstable patients: Is it “time” for a paradigm change?

BackgroundPelvic artery embolization (PAE) is an effective and safe technique for treating postpartum hemorrhage (PPH) with hemodynamic stability. However, its use in hemodynamically unstable patients remains controversial. PurposeTo determine the safety and efficacy of pelvic arterial embolization (PAE) according to the hemodynamic state of primary postpartum hemorrhage (PPH) patients. MethodsThis cohort study was conducted retrospectively, using data from January 2004 to December 2021, in a resource-rich setting at a tertiary Level 1 trauma academic center. A total of 437 patients were diagnosed with PPH during the study period. Of these 437 patients, 161 with primary PPH who underwent PAE were enrolled in the study. The outcomes assessed included the clinical success rate, mortality, the overall success rate, predictive factors for failed PAE, and time-dependent changes in hemodynamic parameters, such as systolic blood pressure (SBP), heart rate (HR), and shock index (SI). Propensity score (PS) matching analysis was performed to assess the influence of specific variables or conditions on the outcomes. ResultsOf the 161 patients who underwent PAE for primary PPH (mean age, 32.9 ± 4.3 [SD]), 85 were retrospectively categorized as having hemodynamic stability (mean age, 32.6 ± 4.1 [SD]), while 76 were categorized as having hemodynamic instability (mean age, 33.3 ± 4.4 [SD]). This study showed PAE for primary PPH had a success rate of 91.9 %, with no significant difference in mortality rates between the groups. The clinical success rate was 98.8 % for patients with hemodynamic stability and 84.2 % for those with hemodynamic instability (p < .001). The overall success rate was 98.8 % for hemodynamic stability and 89.5 % for hemodynamic instability (p = .014). After propensity score matching, the clinical success rate was higher in hemodynamically stable patients than in unstable ones (100 % vs. 86.3 %, p = .013). However, there was no significant difference in the overall success rate (100 % vs. 90.2 %, p = .056). Among the PS-matched population, predictive factors for the failed PAE in primary PPH were hemodynamic instability (adjusted odds ratio [aOR] 21.22, 95 % CI 1.27-355.76; p = .034) and emergency Cesarean delivery with accompanying hemorrhag (aOR 54.00, 95 % CI 11.93-244.56; p = .008). In three groups within a PS-matched population — hemodynamically stable, unstable with successful outcomes, and unstable with unsuccessful outcomes, a generalized linear mixed model (GLMM) analysis for time-dependent changes in hemodynamic parameters revealed a statistically significant difference in SBP, HR, and SI at various time points. ConclusionPelvic arterial embolization of primary postpartum bleeding in hemodynamic instability has been identified as an alternative, safe, and effective life-saving procedure for multidisciplinary treatment in resource-rich environments even after the baseline characteristics are balanced by the PS matching, suggesting it is a primary care option.

336 Differences in pharmacologic management of postpartum hemorrhage in patients with and without thrombocytopenia

336 Differences in pharmacologic management of postpartum hemorrhage in patients with and without thrombocytopenia

"How I wish we could manage such things": A qualitative assessment of barriers to postpartum hemorrhage management and referral in Kenya.

Maternal mortality rates in Kenya have remained high, with the country reporting 342 deaths per 100,000 live births. A major contributor to this is postpartum hemorrhage (PPH), responsible for 40% of maternal deaths in Kenya and the leading cause globally, particularly in low- and middle-income countries. Timely and effective PPH care is crucial; however, challenges arise when referrals between facilities become necessary. Although Primary health care facilities (PHCs) in Kenya oversee many births and are crucial in PPH risk detection and management, they often fall short due to ill-equipped facilities and inefficient referral systems. This study traced PPH patients from tertiary institutions to their initial PHCs. Through qualitative interviews with healthcare providers, we aimed to examine the primary challenges in PPH management and referral decision-making. We found that, in addition to structural gaps, challenges in collaboration and communication between providers from different health facilities, which may also stem from inadequate training, greatly influenced referral efficacy. Our findings are pivotal for maternal health discourse and policy. Importantly, while many solutions focus on structural inputs, our study underscores the importance of communication between facilities in ensuring timely care. Our findings suggest a need for bolstered emergency preparedness, informed clinical decision-making, and strategic interventions where they are most impactful.

Randomized Trial of Early Detection and Treatment of Postpartum Hemorrhage

(N Engl J Med. 2023;389:11–21) Postpartum hemorrhage (PPH) remains the leading cause of maternal death worldwide despite published recommendations from the World Health Organization (WHO) on prevention and treatment. There are challenges in implementing the PPH recommendations. Delay in detection as well as delay in treatment of PPH are 2 reasons the maternal death rate is high. One reason for the delay in detection is due to the ongoing use of visual estimation of blood loss, which often inaccurately underestimates the amount of lost blood. More aggressive interventions for PPH may be delayed until earlier approaches have failed in stopping the blood loss. In some cases, no effective treatment is administered at all. Finally, although the WHO has given these recommendations, not all hospitals and/or medical professionals are implementing them. This study sought to understand whether a treatment bundle referred to as E-MOTIVE could improve early detection and treatment of PPH in patients with a vaginal birth.

Effects of endometriosis on pregnancy outcomes in Fujian province.

Endometriosis is a common gynecological disease, affecting 5 to 10% of women of childbearing age. We analyzed pregnancy complications and neonatal outcomes of patients with pregnancies complicated with endometriosis. The aim of the study was to explore the effects of endometriosis on pregnancy and to evaluate the potential pregnancy risks associated with this disease. The retrospective study included 3,809 parturients who were routinely examined, hospitalized and underwent cesarean section delivery in Fujian Maternal and Child Health Hospital from January 2014 to December 2020. Among them, 1,026 parturients were diagnosed with endometriosis after the cesarean section (endometriosis group), and 2,783 parturients without endometriosis comprised the control group. The endometriosis group was further divided into subgroups according to the severity of the disease: 882 parturients with stage Ⅰ or Ⅱ of endometriosis, and 144 parturients with stage Ⅲ or Ⅳ of endometriosis. General data of all patients and medical records of pregnancy complications and neonatal outcomes for each group were collected and retrospectively analyzed. There were no statistically significant differences in the age, gestational age, gestation, and parity times between all groups (p>0.05). The incidence of preeclampsia and placenta previa in the endometriosis group was higher than that in the control group (p<0.05). There was no significant difference in rates of other pregnancy complications, such as chronic hypertension with pregnancy, preeclampsia with chronic hypertension, hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, gestational diabetes mellitus (GDM), pregestational diabetes mellitus (PGDM), intrahepatic cholestasis of pregnancy (ICP), premature rupture of membranes or placental abruption between the two groups. The incidence of placenta previa in the group of patients with stage III/IV endometriosis was higher than in patients with stage I/II endometriosis (p<0.05). However, there was no significant difference in the incidence of other pregnancy complications. The amount of postpartum hemorrhage (1,000-1,500 ml) in the endometriosis group was greater than that in the control group, and the difference was statistically significant (p<0.05). However, there was no significant difference in the incidence of postpartum hemorrhage in patients with pregnancies complicated with endometriosis at different stages. In pregnant women, endometriosis is associated with an increased incidence of placenta previa that correlates with the severity of the disease. Pregnant women with endometriosis have higher rates of preeclampsia and postpartum hemorrhage, compared to women without endometriosis.

Factors associated with perioperative blood transfusion in women who had postpartum haemorrhage following caesarean delivery

Background: Caesarean delivery is associated with intraoperative blood loss and is a common risk factor for blood transfusion in obstetric practice. Delayed diagnosis and management of obstetric haemorrhage contributes greatly to maternal morbidity and mortality, but patient safety can be enhanced by identifying those at risk. Objective: To evaluate postpartum haemorrhage patients at greater risk for perioperative blood transfusion at caesarean delivery. Methods: A retrospective study was conducted over a two-year period from 1st June 2021 to 31st May 2023. The study population were all consecutive women who underwent caesarean delivery after 28 weeks of gestation, diagnosed as having postpartum haemorrhage (estimated blood loss ≥1000 ml). Women were considered as having the primary outcome if they had intraoperative blood transfusion and/or postoperative transfusion within 24 hours. Data were analyzed with SPSS for Windows version 23. Association between variables were determined using the Chi-square test or Fisher’s exact test as appropriate, and a p-value &lt;0.05 was considered significant. Results: Out of the study population, 55.6% had blood transfusion (43/76). These women received a total of 72 pints of whole blood, with 58.1% (25/43) receiving only one pint. There was a significant relationship between blood transfusion and the type of pregnancy, whether singleton or multiple gestation (P=0.032), placenta previa (P=0.002), and abruptio placenta (P=0.033). Conclusion: Among women who underwent caesarean delivery and had postpartum haemorrhage the prevalence of blood transfusion was high, and placenta previa and abruptio placenta were associated factors for perioperative blood transfusion.

Effiacy of nausicaa compression sutures in terms of PPH management

ABSTRACT;&#x0D; BACKGROUND:Postpartum haemorrhage(PPH) is the most importantr cause of maternal death in Pakistan.Over 125,000 maternal deaths have been reported each year due to PPH. Major causes of PPH include uterine atony and haemorrhage from the placental bed. There is a recent increase in the rate of cesarean section which has increased the incidence of Placenta previa as well as placenta accreta spectrum. Apart from medical management, there are various conservative surgical interventions before imparting to hysterectomy such as uterine compression sutures which effectively secure hemostasis. The Nausicaa compression suture has been a new technique which effectively controls PPH in patients with uterine atony, placenta previa and accrete spectrum.&#x0D; OBJECTIVE: The objective of this study is to determine the efficacy of Nausicaa compression sutures in patientswith PPH undergoing cesarean section.&#x0D; PATIENTS AND METHOD: This study was conducted in the Obstetrics and Gynaecology department of Sir Ganga Ram Hospital,Lahore from 1st September2020 to 30th June,2022. Total of 80 patients who had PPH during cesarean section due to uterine atony or placenta previa spectrum were enrolled after informed consent. Nausicaa compression suture was applied to the anterior, posterior and both uterine walls where required.Successful procedure was those where only Nausicaa compression suture was sufficient to control PPH.&#x0D; RESULTS:The average age of patients was 30.3±4.2 years. There were 24(30%) primigravidas, 28(35%) were G2P1+0 and 28(35%) were multigravidas. The mean gestational age of patients was 37.58 weeks. 46 patients were operated on for indication of placenta previa. 6 patients had placenta accrete. 28 patients had other indications of LSCS. In 9 patients Nausicaa sutures were applied to the anterior uterine wall while in 71 patients to anterior and posterior uterine walls. In 62 patients Nausicaa suture was sufficient to control PPH. 10 patients required other interventions, while 8 patients required emergency hysterectomy due to intractable hemorrhage.&#x0D; CONCLUSION: The Nausicaa compression suture is an effective suture to control postpartum hemorrhage in patients with placenta previa and atonic uterus. It is most effective when applied to anterior and posterior both uterine walls separately.&#x0D; KEY WORDS: Post partum hemorrhage(PPH), Nausicaa Compression suture, Cesarean section.&#x0D;

Clinical benefit of MKANDA SALAMA KIT in a real-world population with Postpartum Hemorrhage. A prospective observational study

Based on Tanzania administrative data and policy Implication report of 2018, revealed that Postpartum hemorrhage contributed to about 29% of all maternal deaths in Tanzania. MKANDA SALAMA KIT (MSK) is the new innovated technological device designed to stop Postpartum hemorrhage (PPH). To determine the effects of MSK on the clinical symptoms improvement, hemodynamic restoration, and bleeding stoppage in post- delivery mothers with PPH. The primary outcome was the composite of Postpartum hemorrhage maternal death and PPH rehospitalization within 42 days follow-up time; secondary outcomes were all causes of maternal death and the occurrence of rehospitalization for worsening PPH -data from 120 women with PPH aged from 13 to 39 years from December 2020 to May 2021 (6 months) at St. Francis referral hospital labor ward were included. Patients were grouped into mild PPH, moderate PPH, and severe PPH. A multinomial regression model was used to determine the associations between risk and outcomes using Statistical Package for Social Sciences software version 21.0". 23% had a previous history of PPH, 36% had maternal hypertension, 45% had anemia, and 12% had maternal diabetes. Mild PPH was 20%, moderate PPH was 37%, and severe PPH was 43%. MSK significantly improved clinical symptoms and signs of all PPH categories by 84%. A significant restoration to normal all hemodynamic parameters was observed to all patients by 79% MSK significantly stopped mild PPH by 100% within 10-20 minutes, while stopped moderate PPH by 70.3% within 10-20 minutes and stopped severe PPH by 63.5% within 10-20 minutes. There was no rehospitalization during follow-up time and no death was reported. MSK significantly improved clinical symptoms, hemodynamic parameters and stopped bleeding in PPH patients, timely application of MSK can significantly prevent PPH maternal death and PPH rehospitalization.

Effect of fibrinogen concentrate on the initial fibrinogen level in trauma and postpartum hemorrhage.

Massive hemorrhage is a serious event that threatens the lives of patients. Fibrinogen concentrate (FC) can control bleeding without causing viral complications and without volume loading, which can happen in transfusion-associated circulatory overload and transfusion-associated acute lung injury. FC application is easy and does not require dissolution or extra devices. It is a cost-effective agent when considering the blood and products used in large quantities. A total of 67 postpartum hemorrhage (PPH) and trauma patients' medical records, who had ASA I-III classification (The American Society of Anesthesiologists classification of physical status), were obtained. Patients were divided into two groups (fibrinogen level ≤ 100 mg/dl and ≥ 101 mg/dl). The following information was obtained from patient files: demographic parameters, history of operations, and laboratory findings (i.e., complete blood counts, coagulation tests, and fibrinogen levels). Also, the duration of intensive care unit stays and mechanical ventilation application days, the administration of fresh frozen plasma (FFP), erythrocytes, platelets, and FC numbers, and tranexamic acid infusion were recorded. There was no mortality in PPH patients in either group (fibrinogen level ≤ 100 mg/dl and ≥ 101 mg/dl). The mortality rate in trauma patients was significantly higher in the group with fibrinogen levels ≤ 100. A total of 170 g of FC were given to PPH patients and 92 g to trauma patients. There were statistically significant differences between the preoperative PT (prothrombin time), postoperative APTT (activated partial thromboplastin time), postoperative PT, and postoperative INR (international normalized ratio) levels of the patients in the group with fibrinogen levels ≤ 100. Mortality rates were also significantly higher, and hospital stays significantly longer in trauma patients in the group with fibrinogen levels ≤ 100. Therapy may be considered during massive bleeding and transfusion, as it can help to increase fibrinogen levels quickly and efficiently. Compared with FFP, fibrinogen concentrate may have some advantages in reducing the risk of fluid overload. FFP contains a range of clotting factors, including fibrinogen. It also contains other proteins and fluids that can lead to fluid overload, especially when given in large volumes during massive transfusions.

Diffusion kurtosis and intravoxel incoherent motion in predicting postpartum hemorrhage in patients at high risk for placenta accreta spectrum disorders.

Placenta accreta spectrum (PAS) disorder encompasses a spectrum of pathologies, from placenta accreta to placenta percreta, which is usually associated with postpartum hemorrhage (PPH). This cross-sectional study enrolled 109 patients suspected of having PAS disorders based on previous ultrasound results or clinical risk factors from November 2018 to March 2022 in Sichuan Provincial People's Hospital. Of the 109 patients, 34 had PPH and 75 did not have PPH. Magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI), intravoxel incoherent motion (IVIM), and diffusion kurtosis imaging (DKI) was performed for each patient and the apparent diffusion coefficient (ADC) from DWI, perfusion fraction (f), pure diffusion coefficient (D), and pseudo-diffusion coefficient (D*) from IVIM, and mean diffusion kurtosis (MK) and mean diffusion coefficient (MD) from DKI were measured and compared. The correlation between the DWI parameters and estimated blood loss (EBL) during surgery was identified using correlation analysis. The diagnostic performance for predicting PPH was compared between the two methods. The amount of bleeding during delivery was positively correlated with D [r=0.331, P<0.001, 95% confidence interval (CI): 0.170 to 0.477], D* (r=0.389, P<0.001, 95% CI: 0.207 to 0.527), f (r=0.222, P=0.02, 95% CI: 0.036 to 0.398), and MD (r=0.277, P=0.003, 95% CI: 0.108 to 0.439), but negatively correlated with MK (r=-0.280, P=0.003, 95% CI: -0.431 to -0.098). In predicting PPH, multivariate analyses showed the independent risk factors were placenta previa and D; the area under the curve (AUC) was 0.795 (95% CI: 0.711 to 0.878) when the two risk factors were combined together. IVIM and DKI parameters are correlated with EBL. The combined use of placenta previa and D are helpful for predicting PPH in patients at high risk of PAS disorders.

Analysis of risk factors associated with different degrees of postpartum hemorrhage in patients with pregnancy-induced hypertension and construction of a prediction model using line graph

Objective This study aims to analyze the risk factors associated with different degrees of postpartum hemorrhage in patients with pregnancy-induced hypertension and construct a prediction model using line graph. Methods The patients who were treated in our hospital for pregnancy-induced hypertension from January 2021 to December 2022 were enrolled as the study subjects. Their clinical data were collected, and the risk factors associated with postpartum hemorrhage in patients with pregnancy-induced hypertension were analyzed by single-factor and multi-factor logistic regression. The nomogram prediction model was constructed and validated internally, and the discrimination and consistency of the model were verified by the ROC curve and calibration graph. Results In this experiment, 125 out of the 482 patients with hypertensive disorder complicating pregnancy experienced different degrees of postpartum hemorrhage, with an incidence of 25.93%. Multivariate Logistic regression analysis showed that patients with severe disease (OR = 2.454), the degree of proteinuria +++ or ++++ (OR = 6.754, 7.206), fetal body mass ≥4000 g (OR = 5.972), uterine atony (OR = 11.789), abnormal HDL-C (OR = 3.174), abnormal LDL-C (OR = 8.812), and abnormal VEGF (OR = 7.702) had a higher risk of postpartum hemorrhage (p < .05). The risk of postpartum hemorrhage was lower in patients with onset gestational week ≥28 weeks (OR = 0.158, 0.025) and delivery gestational week ≥28 weeks (OR = 0.085, 0.152) (p < .05). Columnar line graph models for postpartum hemorrhage in patients with gestational hypertension were constructed based on nine independent risk factors, and the model differentiation (AUC 0.912 and 0.919, respectively) and precision (goodness of fit HL χ 2 = 8.441, p = .392, χ 2 = 7.741, p = .459) were better in the modeling and validation groups. Conclusion The severity of disease, the gestational week upon onset, the gestational week upon delivery, the degree of proteinuria, systolic blood pressure, diastolic blood pressure, uterine atony, HDL-C, LDL-C, VEGF are factors affecting the incidence of postpartum hemorrhage in patients with hypertensive disorder complicating pregnancy. The prediction model based on the above factors can accurately evaluate the risk of different degrees of postpartum hemorrhage in patients with hypertensive disorder complicating pregnancy.

Enhancing postpartum hemorrhage prediction in pernicious placenta previa: a comparative study of magnetic resonance imaging and ultrasound nomogram.

Objective: To explore the risk factors of postpartum hemorrhage (PPH) in patients with pernicious placenta previa (PPP) and to develop and validate a clinical and imaging-based predictive model. Methods: A retrospective analysis was conducted on patients diagnosed surgically and pathologically with PPP between January 2018 and June 2022. All patients underwent PPP magnetic resonance imaging (MRI) and ultrasound scoring in the second trimester and before delivery, and were categorized into two groups according to PPH occurrence. The total imaging score and sub-item prediction models of the MRI risk score/ultrasound score were used to construct Models A and B/Models C and D. Models E and F were the total scores of the MRI combined with the ultrasound risk and sub-item prediction model scores. Model G was based on the subscores of MRI and ultrasound with the introduction of clinical data. Univariate logistic regression analysis and the logical least absolute shrinkage and selection operator (LASSO) model were used to construct models. The receiver operating characteristic curve andision curve analysis (DCA) were drawn, and the model with the strongest predictive ability and the best clinical effect was selected to construct a nomogram. Internal sampling was used to verify the prediction model's consistency. Results: 158 patients were included and the predictive power and clinical benefit of Models B and D were better than those of Models A and C. The results of the area under the curve of Models B, D, E, F, and G showed that Model G was the best, which could reach 0.93. Compared with Model F, age, vaginal hemorrhage during pregnancy, and amniotic fluid volume were independent risk factors for PPH in patients with PPP (p < 0.05). We plotted the DCA of Models B, D, E, F, and G, which showed that Model G had better clinical benefits and that the slope of the calibration curve of Model G was approximately 45°. Conclusion: LASSO regression nomogram based on clinical risk factors and multiple conventional ultrasound plus MRI signs has a certain guiding significance for the personalized prediction of PPH in patients with PPP before delivery.

The association between body mass index and postpartum hemorrhage after cesarean delivery

We aimed to evaluate the association between obesity and postpartum hemorrhage (PPH) after cesarean delivery (CD). This was a retrospective cohort study using a multicenter database of 20 hospitals in the United States. We analyzed 27,708 patients undergoing CD from 2015 to 2019. The exposure of interest was BMI, and the primary outcome was PPH (estimated blood loss [EBL] ≥ 1000 mL). Simple logistic regression was used to evaluate the relationship between obesity and intrapartum complications. Multivariable logistic regression was used to adjust for any confounding demographic variables. Hosmer and Lemeshow’s purposeful selection algorithm was adapted to develop a multivariable logistic regression model of PPH. Analyses were conducted using STATA 16.1 (College Station, Texas) with p ≤ 0.05 considered significant. BMI exerted a significant effect on the frequency of PPH (p = 0.004). Compared to patients with BMI 18.5–24.9 kg/m2, patients with BMI between 25 and 59.9 kg/m2 had an increased odds of PPH. The odds of PPH in patients with BMI > 60 kg/m2 was not increased compared to patients with BMI 18.5–24.9 kg/m2. Obesity was associated with a decreased odds of blood transfusion (aOR 0.73, 95% CI 0.55–0.97). In conclusion, higher BMI was associated with PPH yet a lower odds of transfusion after CD.
