Care of late intrauterine fetal death and stillbirth: Green-top Guideline No. 55.

A combination of mifepristone and a prostaglandin preparation should usually be recommended as the first-line intervention for induction of labour (Grade B). A single 200 milligram dose of mifepristone is appropriate for this indication, followed by: 24+0-24+6 weeks of gestation - 400 micrograms buccal/sublingual/vaginal/oral of misoprostol every 3 hours; 25+0-27+6 weeks of gestation - 200 micrograms buccal/sublingual/vaginal/oral of misoprostol every 4 hours; from 28+0 weeks of gestation - 25-50 micrograms vaginal every 4 hours, or 50-100 micrograms oral every 2 hours [Grade C]. There is insufficient evidence available to recommend a specific regimen of misoprostol for use at more than 28+0 weeks of gestation in women who have had a previous caesarean birth or transmural uterine scar [Grade D]. Women with more than two lower segment caesarean births or atypical scars should be advised that the safety of induction of labour is unknown [Grade D]. Staff should be educated in discussing mode of birth with bereaved parents. Vaginal birth is recommended for most women, but caesarean birth will need to be considered for some [Grade D]. A detailed informed discussion should be undertaken with parents of both physical and psychological aspects of a vaginal birth versus a caesarean birth [Grade C]. Parents should be cared for in an environment that provides adequate safety according to individual clinical circumstance, while meeting their needs to grieve and feel supported in doing so (GPP). Clinical and laboratory tests should be recommended to assess maternal wellbeing (including coagulopathy) and to determine the cause of fetal death, the chance of recurrence and possible means of avoiding future pregnancy complications [GradeD]. Parents should be advised that with full investigation (including postmortem and placental histology) a possible or probable cause can be found in up to three-quarters of late intrauterine fetal deaths [Grade B]. All parents should be offered cytogenetic testing of their baby, which should be performed after written consent is given (GPP). Parents should be advised that postmortem examination can provide information that can sometimes be crucial to the management of future pregnancy [Grade B].

Perceptions and experiences with two no-test direct-to-patient telehealth medication abortion regimens in the USA: an exploratory study with mifepristone and misoprostol and misoprostol-only regimens

IntroductionTelehealth medication abortion (teleMAB) is an option for expanding abortion access in the USA. In this study, we compared the accessibility of two no-test, direct-to-patient teleMAB regimens: mifepristone and misoprostol,...

Reduced Misoprostol Regimen versus Standard Misoprostol Regimen for Induction of Second Trimester Abortion in Patients with Previous Cesarean Section Scar

Reduced Misoprostol Regimen versus Standard Misoprostol Regimen for Induction of Second Trimester Abortion in Patients with Previous Cesarean Section Scar

Risk Factors for Failure of Second-Trimester Termination with Misoprostol as a Single Agent.

Background: Understanding the potential risk factors for failure of pregnancy termination is crucial for informed clinical decision making. Such insights can assist clinicians in adjusting the dosage or route of various regimens, as well as in counseling patients and predicting the likelihood of successful outcomes. However, research on these risk factors has been limited, and existing studies have yielded inconsistent results. To address this gap, we conducted a study with a large sample size, focusing on identifying the potential risk factors for failure of second-trimester termination using misoprostol as a single agent, specifically between 14 and 28 weeks of gestation. Methods: A secondary analysis based on a database of second-trimester terminations was conducted. The inclusion criteria were a singleton pregnancy, gestational age between 14 and 28 weeks, an unfavorable cervix, no spontaneous labor pain, intact membranes, and termination with misoprostol alone. Potential risk factors for failure of termination, defined as no abortion within 48 h, were analyzed using univariate and multivariate analyses. Results: A total of 1094 cases were included in the analysis, consisting of 991 successful cases and 103 (9.4%) cases of failure. The significant risk factors for failure of termination included early gestational age, live fetuses, sublingual regimen of 400 mcg every 6 h, and high maternal pre-pregnancy BMI. Previous cesarean sections and lower Bishop scores tended to increase the risk but did not reach a significant level. Conclusions: Second-trimester termination with misoprostol as a single agent was highly effective, with a failure rate of 9.4%. The risk factors for failure included gestational age, fetal viability, misoprostol regimen, and maternal pre-pregnancy BMI, suggesting that these factors should be taken into consideration for second-trimester terminations with misoprostol.

Vaginal dinoprostone insert compared with two different oral misoprostol regimens for labor induction in nulliparous and multiparous women.

Labor induction exhibits considerable variations in protocols and medication regimens. Limited studies compare vaginal dinoprostone inserts with different oral misoprostol dosages, considering parity influence. This study explores the distinctions among 10 mg vaginal dinoprostone inserts and oral misoprostol 25 μg every 2 and every 4 h for labor induction, stratified by parity. This retrospective cohort study involved 607 participants across two hospitals. The primary outcome, time from induction to delivery, and secondary outcomes, including mode of delivery and maternal and fetal safety, were assessed. Patient characteristics revealed differences in indication for labor induction, with the dinoprostone cohort having fewer post-term and premature rupture of membranes cases but more intrauterine growth restriction/small-for-gestational age. Both oral misoprostol regimens showed a shorter time to delivery interval compared to the dinoprostone cohort (median: 1380 min [IQR 1381.0] and 1127.0 min [IQR 1214.0] versus 1631.5 [IQR 1736.2], p < 0.001 and p = 0.014). Only the difference between oral misoprostol q2h and vaginal dinoprostone remained significant for nulliparous but not multiparous women, losing significance over all the population after adjusting for confounding factors. The proportion of women giving birth within 24 h did not significantly differ between misoprostol q2h and dinoprostone after adjusting for confounders. When comparing misoprostol q4h with dinoprostone after confounder adjustment, an increased time to delivery interval for misoprostol q4h was found (p = 0.001). Both oral misoprostol regimens exhibited fewer meconium-stained liquor (miso q4h: OR 0.44, miso q2h: OR 0.34) and cesarean sections (miso q4h: OR 0.48, miso q2h: OR 0.53) compared to dinoprostone, even after adjustment for confounders. Our study suggests that oral misoprostol 25 μg q4h is less effective than 10 mg vaginal dinoprostone for labor induction if parity and indication for induction are adjusted for, particularly in multiparous women. In terms of side effects, oral misoprostol regimens seem superior to vaginal dinoprostone. Our data support the individualized use of different agents for labor induction according to parity, indication for induction, bishop score, and women's preference.

Comparison of No-Test Telehealth and In-Person Medication Abortion

In the US, access to medication abortion using history-based (no-test) eligibility assessment, including through telehealth and mailing of mifepristone, has grown rapidly. Additional evidence on the effectiveness and safety of these models is needed. To evaluate whether medication abortion with no-test eligibility assessment and mailing of medications is as effective as in-person care with ultrasonography and safe overall. Prospective, observational study with noninferiority analysis. Sites included 4 abortion-providing organizations in Colorado, Illinois, Maryland, Minnesota, Virginia, and Washington from May 2021 to March 2023. Eligible patients were seeking medication abortion up to and including 70 days' gestation, spoke English or Spanish, and were aged 15 years or older. Study groups reflected the model of care selected by the patient and clinicians and included: (1) no-test (telehealth) eligibility assessment and mailing of medications (no-test + mail) (n = 228); (2) no-test eligibility assessment and pickup of medications (no-test + pickup) (n = 119); or (3) in-person with ultrasonography (n = 238). Effectiveness, defined as a complete abortion without the need for repeating the mifepristone and misoprostol regimen or a follow-up procedure, and safety, defined as an abortion-related serious adverse event, including overnight hospital admission, surgery, or blood transfusion. Outcomes were derived from patient surveys and medical records. Primary analysis focused on the comparison of the no-test + mail group with the in-person with ultrasonography group. The mean age of the participants (N = 585) was 27.3 years; most identified as non-Hispanic White (48.6%) or non-Hispanic Black (28.1%). Median (IQR) gestational duration was 45 days (39-53) and comparable between study groups (P = .30). Outcome data were available for 91.8% of participants. Overall effectiveness was 94.4% (95% CI, 90.7%-99.2%) in the no-test + mail group and 93.3% (95% CI, 88.3%-98.2%) in the in-person with ultrasonography group in adjusted models (adjusted risk difference, 1.2 [95% CI, -4.1 to 6.4]), meeting the prespecified 5% noninferiority margin. Serious adverse events included overnight hospitalization (n = 4), blood transfusion (n = 2), and emergency surgery (n = 1) and were reported by 1.1% (95% CI, 0.4%-2.4%) of participants, with 3 in the no-test + mail group, 3 in the in-person with ultrasonography group, and none in the no-test + pickup group. This prospective, observational study found that medication abortion obtained following no-test telehealth screening and mailing of medications was associated with similar rates of complete abortion compared with in-person care with ultrasonography and met prespecified criteria for noninferiority, with a low prevalence of adverse events.

Effect of Maternal Age and Body Mass Index on Induction of Labor Using Oral Misoprostol in Late-Term Pregnancies: A Retrospective Cross-Sectional Study

Introduction: Several studies have shown that late- and post-term pregnancies are associated with an increased risk of perinatal morbidity and mortality. In this case, induction of labor is the recommended approach. For full-term pregnancies, various methods exist to prepare the cervix and/or commence labor. Prostaglandins serve the dual purpose of cervical ripening and labor induction, blurring the distinction between the two processes. The aim of this research was to evaluate the effect of maternal age and body mass index (BMI) on oral misoprostol induction of labor for late-term pregnancies. Methods: This was a retrospective cross-sectional study (ClinicalTrial ID: NCT06184139), including only late-term pregnancies in healthy nulliparous women carrying a single cephalic fetus with normal birthweight who underwent induction of labor with oral misoprostol. We used the oral misoprostol regimen proposed by the World Health Organization (WHO) for induction of labor in term singleton pregnancies in women who have not had a previous cesarean delivery and a Bishop score <7. The regimen was oral misoprostol in aqueous solution at the low dose of 25 μg every 2 h until a Bishop score ≥7, labor, or for a maximum of 8 doses. Results: One hundred and four pregnant women underwent induction of labor with oral misoprostol for late-term pregnancy on the 290th day of gestation. Study population was divided in two groups based on age (<35 and ≥35 years) and obesity (BMI <30 and ≥30). No statistically significant differences were recorded between younger and older women. Obese women reported a longer time between the last dose of misoprostol and cervical dilation of 6 cm (p = 0.01), a longer time between the last dose of misoprostol and delivery (p = 0.04), and a higher rate of grade II vaginal lacerations (p = 0.02). Conclusions: Maternal BMI is a factor negatively influencing the efficacy of oral misoprostol for induction of labor in late-term pregnancy.

Induction of abortion in the first trimester of pregnancy using letrozole and misoprostol combination versus misoprostol alone - A comparative observational study

Background: Medical abortion is safer than surgical abortion. Several studies have shown that combination of antiprogesterone drug mifepristone and prostaglandin misoprostol can increase complete abortion rate in medical management of first-trimester miscarriage compared to misoprostol alone. Letrozole, an aromatase inhibitor, has emerged as an alternative to mifepristone for induction of medical abortion as mifepristone is expensive and not registered in many countries. Aims and Objectives: The aim of the present study was to evaluate the safety and efficacy of combined regimen of letrozole and misoprostol in first-trimester medical abortion compared to misoprostol alone. Materials and Methods: It was a comparative observational study conducted at R. G. Kar Medical College, a tertiary care hospital in West Bengal, India. The study population was the antenatal mothers booked at antenatal clinic willing for termination of pregnancy at &lt;12 weeks of gestational age. Participants were allocated, 39 in each group in a non-randomized manner. Patients in one group (Group A) were posted for medical abortion with combination regimen of tablet letrozole (10 mg) once daily for 3 days followed by application of tablet misoprostol 800 mcg sublingually on day 4. In other group (Group B), patients were on misoprostol-only regimen with the application of tablet misoprostol 800 mcg sublingually. Results: Induction-abortion time was significantly less in the letrozole group (11±0.79 h) than the misoprostol group (13.23±0.81 h), P=0.0001. Complete abortion rate was significantly higher in the letrozole group compared to misoprostol group (84.62% and 64.10%, respectively, P=0.03). 15.38% patients in the letrozole group and 35.90% patients in the misoprostol group had excessive vaginal bleeding and the difference was statistically significant, P=0.03. The duration of vaginal bleeding was also significantly less in the letrozole group (2.45±0.29 days) than the misoprostol group (2.82±0.37 days), P&lt;0.0001. Incidence of side-effects was comparable and the severity of side-effects was not significantly different between the groups. Conclusion: Letrozole and misoprostol combination regimen leads to significant increase in complete abortion rate and also significant reduction of the duration of vaginal bleeding, induction-abortion time, and need for surgical intervention when compared to misoprostol regimen.

Experiences with misoprostol-only used for self-managed abortion and acquired from an online or retail pharmacy in the United States

ObjectivesThis study aimed to understand individual experiences with medication abortion using misoprostol-only among people living in the United States. Study designWe conducted 31 semistructured anonymous in-depth interviews with individuals who used misoprostol-only for self-managed medication abortion. Participants were recruited from Aid Access, an online telemedicine organization that provided prescriptions for misoprostol to eligible people in all 50 states in May and June 2020 when a combined mifepristone and misoprostol regimen was unavailable. We coded transcripts with a flexible coding approach and focused on perceptions and experiences with use. ResultsParticipants were knowledgeable about misoprostol. Previous abortion experiences shaped perceptions of misoprostol-only by allowing comparison to the mifepristone and misoprostol regimen. Most participants expressed an unwavering desire for an effective abortion method, regardless of the medications or regimen. Individual physical experiences with misoprostol, including bleeding, cramping, nausea, and diarrhea, varied in intensity and duration. Participants proactively managed symptoms with self-care strategies and drew extensively from their prior experiences with menstruation, miscarriage, abortion, and childbirth. Clear instructions and information on potential complications and what to expect throughout the abortion fostered a sense of preparedness, and personalized interactions with an online help desk brought comfort. ConclusionsMisoprostol offered an essential abortion method for study participants. This regimen was physically challenging for some, and there is potentially a greater need for communication and support for individuals using misoprostol-only regimens. Prior reproductive experiences informed participant’s knowledge, preparedness, pain management, and ability to both recognize and manage potential complications. ImplicationsAs restrictions on mifepristone continue, more people may use misoprostol-only regimens. All regimens can be supported with detailed instructions, clear expectations, information on signs of potential complications, and personalized support. To achieve reproductive autonomy, people must have access to a range of abortion care options that meet their needs.

Evaluation of a "smart" screening tool for asynchronous assessment of medication abortion eligibility: A pilot study

ObjectivesThis study aimed to assess the feasibility, safety, and acceptability of asynchronous screening for medication abortion eligibility using a programmed questionnaire. Study designFor this study, we developed an informational website about medication abortion with a linked questionnaire programmed to produce a conclusion regarding eligibility according to standard criteria. We enrolled people in Colorado and Minnesota who submitted questionnaires indicating eligibility. A study physician reviewed each questionnaire and medical records if available and determined whether the responses warranted treatment without a synchronous clinical consultation or ultrasound. If so, the physician prescribed a standard regimen of mifepristone and misoprostol. We collected posttreatment data on abortion outcome, adverse events, and satisfaction. ResultsWe received questionnaires from 197 individuals, of whom 160 remained in the study until the physician made a final treatment decision. Physicians prescribed medication abortion to 156 (97.5%) individuals based on the questionnaire responses, whereas four needed further assessment to confirm eligibility. Of the 156 individuals, 130 had sufficient follow-up to assess abortion outcome, and 123 (95%) had complete medication abortions without additional treatment. One participant was hospitalized for bleeding, and one expelled a 15-week fetus; however, it is not clear that conventional synchronous history-based screening would have averted these events. Of the 197 questionnaires, 42% were submitted outside business hours. On satisfaction questionnaires, 134 (96%) of 144 participants said they would recommend the study to a friend who needed an abortion. ConclusionsData from this pilot project suggest that providing medication abortion based only on a self-administered, programmed questionnaire is likely to be effective, safe, efficient, and acceptable. ImplicationsA programmed self-administered patient questionnaire to assess eligibility for medication abortion could reduce the cost of the service, augment clinic efficiency, improve quality of care, and enhance access to abortion.

Prior Cesarean Birth and Risk of Uterine Rupture in Second-Trimester Medication Abortions Using Mifepristone and Misoprostol: A Systematic Review and Meta-analysis.

To assess the risk difference of uterine rupture when using current mifepristone and misoprostol regimens for second-trimester abortion among individuals with prior cesarean birth compared with those without prior cesarean birth. We searched the terms second trimester, induction, mifepristone, and abortion in PubMed, EMBASE, POPLINE, ClinicalTrials.gov , and Cochrane Library from inception until December 2022. We included randomized trials and observational studies including a mixed cohort, with and without uterine scar, of individuals at 14-28 weeks of gestation who used mifepristone and misoprostol to end a pregnancy or to manage a fetal death. We excluded case reports, narrative reviews, and studies not published in English. Two reviewers independently screened studies. Absolute risks with binomial CIs were calculated from pooled data. Using R software, we estimated total risk difference by the Mantel-Haenszel random-effects method without continuity correction. For studies with zero events, a continuity correction of 0.5 was applied for individual risk differences and plotted graphically with forest plots. Statistical heterogeneity was assessed with Higgins I2 statistics. Funnel plot assessed for publication bias. Of 198 articles identified, 22 met the inclusion criteria: seven randomized trials (n=923) and 15 observational studies (n=6,195). Uterine rupture risk with prior cesarean birth was 1.1% (10/874) (95% CI 0.6-2.1) and without prior cesarean birth was 0.01% (2/6,244) (95% CI 0.0-0.12). The risk difference was 1.23% (95% CI 0.46-2.00, I2 =0%). Of the 12 reported uterine ruptures, three resulted in hysterectomy. Uterine rupture with mifepristone and misoprostol use during second-trimester induction abortion is rare, with the risk increased to 1% in individuals with prior cesarean birth.

Society of Family Planning Clinical Recommendation: Medication abortion between 14 0/7 and 27 6/7 weeks of gestation: Jointly developed with the Society for Maternal-Fetal Medicine.

The objective of this Clinical Recommendation is to review relevant literature and provide evidence-based recommendations for medication abortion between 14 0/7 and 27 6/7 weeks of gestation, with a focus on mifepristone-misoprostol and misoprostol-only regimens. We systematically reviewed PubMed articles published between 2008 and 2022 and reviewed reference lists of included articles to identify additional publications. See Search Strategy for more details. Several randomized trials of medication abortion between 14 0/7 and 27 6/7 weeks of gestation demonstrate that mifepristone 200 mg orally before misoprostol increases effectiveness (complete abortion at 24 or 48 hours) compared to misoprostol only. Studies continue to evaluate different doses, routes, and dosing intervals for misoprostol. If mifepristone is unavailable, several misoprostol regimens with individual doses of at least 200 mcg or more are effective. Adjunctive osmotic dilators are of limited benefit. It is important to individualize care, with consideration to reducing misoprostol dose in low-resource settings or at 24 0/7 weeks of gestation or later (or equivalent uterine size). Misoprostol in the setting of two or more previous cesarean sections is associated with increased risk of uterine rupture compared to one or none, but risk remains low. Most contraceptives can be started during or immediately following abortion. Appropriately trained and credentialed advanced practice clinicians can provide medication abortion between 14 0/7 and 27 6/7 weeks of gestation with appropriate backup within the confines of local regulations and licensure.

The efficacy and safety of 25 μg or 50 μg oral misoprostol versus 25 μg vaginal misoprostol given at 4- or 6-hourly intervals for induction of labour in women at or beyond term with live singleton pregnancies: A systematic review and meta-analysis.

Misoprostol is widely used for cervical ripening and labour induction as it is heat-stable and inexpensive. Oral misoprostol 25 μg given 2-hourly is recommended over vaginal misoprostol 25 μg given 6-hourly, but the need for 2-hourly fetal monitoring makes oral misoprostol impractical for routine use in high-volume obstetric units in resource-constrained settings. To compare the efficacy and safety of oral misoprostol initiated at 25 or 50 μg versus 25 μg vaginal misoprostol given at 4- to 6-hourly intervals for labor induction in women at or beyond term (≥ 37 weeks) with a single viable fetus and an unscarred uterus. We identified eligible randomized, parallel-group, labor-induction trials from recent systematic reviews. We additionally searched PubMed, Cochrane CENTRAL, Epistemonikos, and clinical trials registries from February 1, 2020 to December 31, 2022 without language restrictions. Database-specific keywords for cervical priming, labor induction, and misoprostol were used. We excluded labor-induction trials exclusively in women with ruptured membranes, in the third trimester, and those that initiated misoprostol at doses not specified in the review's objectives. The primary outcomes were vaginal birth within 24 h, cesarean section, perinatal mortality, neonatal morbidity, and maternal morbidity. The secondary outcomes were uterine hyperstimulation with fetal heart rate changes, and oxytocin augmentation. Two or more authors selected studies independently, assessed risk of bias, and extracted data. We derived pooled weighted risk ratios with 95% confidence intervals (CIs) for each outcome, subgrouping trials by the dose and frequency of misoprostol regimens. We used the I2 statistic to quantify heterogeneity and the random-effects model for meta-analysis when appropriate. We used the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach to assess certainty (confidence) in the effect estimates. Thirteen trials, from Canada, India, Iran, and the US, randomizing 2941 women at ≥37 weeks of gestation with an unfavorable cervix (Bishop score <6), met the eligibility criteria. Five misoprostol regimens were compared: 25 μg oral versus 25 μg vaginal, 4-hourly (three trials); 50 μg oral versus 25 μg vaginal, 4-hourly (five trials); 50 μg followed by 100 μg oral versus 25 μg vaginal, 4-hourly (two trials); 50 μg oral, 4-hourly versus 25 μg vaginal, 6-hourly (one trial); and 50 μg oral versus 25 μg vaginal, 6-hourly (two trials). The overall certainty in the evidence ranged from moderate to very low, due to high risk of bias in 11/13 trials (affecting all outcomes), unexplained heterogeneity (1/7 outcomes), indirectness (1/7 outcomes), and imprecision (4/7 outcomes). Vaginal misoprostol probably increased vaginal deliveries within 24 h compared with oral misoprostol (risk ratio [RR] 0.82, 95% CI 0.70-0.96; 11 trials, 2721 mothers; moderate-certainty evidence); this was more likely with 4-hourly than with 6-hourly vaginal regimens. The risk of cesarean sections did not appreciably differ (RR 1.00, 95% CI 0.80-1.26; 13 trials, 2941 mothers; very low-certainty evidence), although oral misoprostol 25 μg 4-hourly probably increased this risk compared with 25 μg vaginal misoprostol 4-hourly (RR 1.69, 95% CI 1.21-2.36; three trials, 515 mothers). The risk of perinatal mortality (RR 0.67, 95% CI 0.11-3.90; one trial, 196 participants; very low-certainty evidence), neonatal morbidity (RR 0.84, 95% CI 0.67-1.06; 13 trials, 2941 mothers; low-certainty evidence), and maternal morbidity (RR 0.83, 95% CI 0.48-1.44; 6 trials; 1945 mothers; moderate-certainty evidence) did not differ appreciably. The risk of uterine hyperstimulation with fetal heart rate changes may be lower with oral misoprostol (RR 0.70, 95% CI 0.52-0.95; 10 trials, 2565 mothers; low-certainty evidence). Oxytocin augmentation was probably more frequent with oral compared with vaginal misoprostol (RR 1.29, 95% CI 1.10-1.51; 13 trials, 2941 mothers; moderate-certainty evidence). Low-dose, 4- to 6-hourly vaginal misoprostol regimens probably result in more vaginal births within 24 h and less frequent oxytocin use compared with low-dose, 4- to 6-hourly, oral misoprostol regimens. Vaginal misoprostol may increase the risk of uterine hyperstimulation with fetal heart changes compared with oral misoprostol, without increasing the risk of perinatal mortality, neonatal morbidity, or maternal morbidity. Indirect evidence indicates that 25 μg vaginal misoprostol 4-hourly may be more effective and as safe as the recommended 6-hourly vaginal regimen. This evidence could inform clinical decisions in high-volume obstetric units in resource-constrained settings.

Comparing the Effects of Misoprostol/Letrozole and Misoprostol/Placebo on Medical Abortion Success Rate: A Randomized Clinical Trial

Background: Abortion is the medical or surgical termination of pregnancy before the 20th week. However, dilation and curettage have been associated with hazards such as uterine rupture, heavy bleeding, and infection. Therefore, in recent decades, pharmacological therapies have become more widely accepted. Objectives: This research compared the medical abortion success rates of misoprostol/letrozole versus misoprostol/placebo. Methods: This randomized clinical study was conducted at Mashhad University of Medical Sciences hospitals between 2018 and 2019, involving pregnant women who were candidates for medical abortion. The study population was divided into two groups based on whether they had undergone cesarean section (CS). Each group was randomly assigned to either a control or an intervention group. In the CS group, there were 52 patients in the intervention group and 52 in the control group. The control group received a regimen of misoprostol and placebo, while the intervention group received a combination of misoprostol and letrozole. Results: There was no statistically significant difference in age (31.59 ± 5.6 vs. 31.06 ± 4.6, P value = 0.605), gestational age by ultrasound (11.20 ± 3.3 vs. 10.29 ± 2.6, P value = 0.135), or blood pressure between the control and intervention groups. However, the analysis showed a statistically significant difference in the rate of complete abortion (12 (23.5%) vs. 28 (54.9%), P value = 0.001) between the two groups. In the non-CS group, there was a significant difference in age between the control and intervention groups. The study analyses also revealed a significant difference in the rate of complete abortion between the two groups (24 (46.2%) vs. 36 (72.0%), P value = 0.008). Conclusions: Letrozole is recommended in combination with misoprostol for medical abortions because it increases the likelihood of complete abortion and reduces the duration of the abortion process.

Comparison between different dose regimens of misoprostol in termination of early pregnancy

Objective: compares efficacy &amp; side effects of vaginal put of 400 or 600 microgram of cytotic in repeated doses in termination of first trimester gestational age. Desgn: Randomized prospect study. Setting and duration of study: Maternity teaching hospital in Sulaimani from 1st of January to the end of June 2009. Patients and methods: This study was included 90 pregnant women admitted during first trimester of gestation, requiring termination of pregnancy because of fetal demise. These patient are divided into two groups: (45) women received 600 mcg of misoprostol vaginally and other group 45 were received 400 mcg of it also vaginally. Misoprostol was given every 6hr for three doses. They were observed and evaluated in 24 hours.Result: Group1 had a complete abortion rate of 35.6% while group2 abortion rate of 13.3% this was significant. The time interval from put abortion was 8.04 ± 4.280 hours in group1 and 9.62 ± 5.237 hours in group2. Side effects such as diarrhea, nausea and headache showed no statistically significant difference in both patients.

Availability of medical abortion medicines in eight countries: a descriptive analysis of key findings and opportunities

BackgroundIn recent years a growing number of manufacturers and medical abortion products have entered country markets and health systems, with varying degrees of quality and accessibility. An interplay of factors including pharmaceutical regulations, abortion laws, government policies and service delivery guidelines and provider’s knowledge and practices influence the availability of medical abortion medicines. We assessed the availability of medical abortion in eight countries to increase understanding among policymakers of the need to improve availability and affordability of quality-assured medical abortion products at regional and national levels.MethodsUsing a national assessment protocol and an availability framework, we assessed the availability of medical abortion medicines in Bangladesh, Liberia, Malawi, Nepal, Nigeria, Rwanda, Sierra Leone and South Africa between September 2019 and January 2020.ResultsRegistration of abortion medicines—misoprostol or a combination of mifepristone and misoprostol—was established in all countries assessed, except Rwanda. Mifepristone and misoprostol regimen for medical abortion was identified on the national essential medicines list/standard treatment guidelines for South Africa as well as in specific abortion care service and delivery guidelines for Bangladesh, Nepal, Nigeria, and Rwanda. In Liberia, Malawi, and Sierra Leone—countries with highly restrictive abortion laws and no abortion service delivery guidelines or training curricula—no government-supported training on medical abortion for public sector providers had occurred. Instead, training on medical abortion was either limited in scope to select private sector providers and pharmacists or prohibited. Community awareness activities on medical abortion have been limited in scope across the countries assessed and where abortion is broadly legal, most women do not know that it is an option.ConclusionUnderstanding the factors that influence the availability of medical abortion medicines is important to support policymakers improve availability of these medicines. The landscape assessments documented that medical abortion commodities can be uniquely impacted by the laws, policies, values, and degree of restrictions placed on service delivery programs.

A Comparison of Two Dosing Regimens of Misoprostol in Labour Induction: A Randomised Controlled Trial

Objective: To compare the effectiveness and safety of 50μg of sublingual misoprostol administered six (6) hourly to that of 50μg of vaginal misoprostol administered four (4) hourly. Methodology: A non-blinded, randomized controlled trial conducted from Sept 1, 2014, to Nov 31, 2014, at a tertiary hospital in Ghana. Hundred and sixty women with medical or obstetric indications for labour induction were randomized into two groups. Results: The rate of vaginal delivery, caesarean section, uterine tachysystole and uterine hyperstimulation were similar in both groups. Sixty-three (78.8%) and 66 (82.5%) mothers in the vaginal and sublingual groups delivered vaginally. More (10.0%) mothers in the vagina group required emergency caesarean for foetal distress. Six (vaginal group) and 8 (sublingual group) of the mothers required emergency caesarean for cephalopelvic disproportion. Three mothers from each group had an emergency caesarean section due to failed labour induction. Almost the same number of mothers had uterine tachysystole in both groups. More (3.8%) mothers in the vaginal group had uterine hyperstimulation. Differences in the mean induction delivery interval and the need for oxytocin augmentation were not significant. No differences were found in the intrapartum passage of meconium, blood loss in the third stage of labour, 5-minute Apgar score &lt;7, and neonatal intensive care unit admissions. Conclusion: The sublingual regimen was as effective and safe as the vaginal regimen in achieving vaginal delivery.

Comparison of mifepristone plus misoprostol with misoprostol alone for first trimester medical abortion: A systematic review and meta-analysis.

To compare mifepristone plus a misoprostol-combined regimen with misoprostol alone in the medical abortion of first trimester pregnancy. An internet-based search of available literature was performed using text words contained in titles and abstracts. PubMed/Medline, Cochrane CENTRAL, EMBASE, and Google scholar were used to locate English-based articles published until December 2021. Studies fulfilling the inclusion criteria were selected, appraised, and assessed for methodological quality. The included studies were pooled for meta-analysis, and the results were presented in risk ratio at a 95% confidence interval. Nine studies comprising 2,052 participants (1,035 intervention and 1,017 controls) were considered. Primary endpoints were complete expulsion, incomplete expulsion, missed abortion, and ongoing pregnancy. The intervention was found to more likely induce complete expulsion irrespective of gestational age (RR: 1.19; 95% CI: 1.14-1.25). The administration of misoprostol 800 mcg after 24 h of mifepristone pre-treatment in the intervention group more likely induced complete expulsion (RR: 1.23; 95% CI: 1.17-1.30) than after 48 h. The intervention group was also more likely to experience complete expulsion when misoprostol was used either vaginally (RR: 1.16; 95% CI: 1.09-1.17) or buccally (RR: 1.23; 95% CI: 1.16-1.30). The intervention was more effective in the subgroup with a negative foetal heartbeat at reducing incomplete abortion (RR: 0.45; 95% CI: 0.26-0.78) compared with the control group. The intervention more likely reduced both missed abortion (RR: 0.21; 95% CI: 0.08-0.91) and ongoing pregnancy (RR: 0.12; 95% CI: 0.05-0.26). Fever was less likely to be reported (RR: 0.78; 95% CI: 0.12-0.89), whereas the subjective experience of bleeding was more likely to be encountered (RR: 1.31; 95% CI: 1.13-1.53) by the intervention group. The review strengthened the theory that a combined mifepristone and misoprostol regimen can be an effective medical management for inducing abortions during first trimester pregnancy in all contexts. Specifically, there is a high-level certainty of evidence on complete expulsion during the early stage and its ability to reduce both missed and ongoing pregnancies. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42019134213, identifier CRD42019134213.

Tech-ing the Trade: Notes on Reformulating Abortion and Its History.

Tech-ing the Trade: Notes on Reformulating Abortion and Its History Kelly O’Donnell (bio) In the introduction to her 2014 treatise Pro: Reclaiming Abortion Rights, feminist author Katha Pollitt confessed that in the face of mounting legal restrictions and the degrading landscape of abortion care in many parts of the country, she found herself daydreaming, there is something, some substance already in common use, that women could drink after sex or at the end of the month, that would keep them unpregnant with no one the wiser. Something you could buy at the supermarket, or maybe several things you could mix together, items so safe and so ordinary they could never be banned, that you could prepare in your own home, that would flush your uterus and leave it pink and shiny and empty without you ever needing to know if you were pregnant or about to be. A brew of Earl Grey, Lapsang Souchong, and ground cardamom, say. Or Coca-Cola with a teaspoon of Nescafé and a dusting of cayenne pepper. Things you might have on your shelves right now, just waiting for some clever person to put them together, some stay-at-home mother with a chemistry degree rattling around her kitchen late at night.1 Such a substance, she claimed, would subvert “the whole elaborate panopticon that governs abortion today.” This was partially the promise, Pollitt observed, of mifepristone, otherwise known as RU-486—but “the French abortion pill” had as yet failed to deliver. Few doctors were prescribing it, the law regulated it just as heavily as surgical abortions, and it was still fairly difficult to obtain.2 The allure of the abortifacient lingered, but no pregnancy-ending panaceas seemed forthcoming. By 2020, only a few years later, the landscape of abortion care in the United States had changed dramatically. Hastened in part due to the COVID-19 pandemic and its many disruptions of routine medical practice, medication abortion suddenly accounted for more than half of all [End Page 57] abortions in the country, jumping from 39 percent in 2013 to 54 percent in 2020 according to Centers for Disease Control and Prevention data (as reported recently by the Guttmacher Institute). Approved for use up to ten weeks of pregnancy, the combined regimen of misoprostol and mifepristone pills, taken sequentially over a series of a few days, is now the procedure of choice for early pregnancy termination.3 That same year, the American College of Obstetricians and Gynecologists (ACOG) issued an updated practice bulletin regarding the use of medication abortion, outlining its safe use for up to seventy days of gestation. The organization found that “patients can safely and effectively” use or administer medication abortion at home, and that “routine in-person follow-up is not necessary after uncomplicated medication abortion.” However, the Food and Drug Administration’s regulatory guidance around one of the drugs—mifepristone—required that it be administered in person, under the guidance of a medical professional. After taking this part of the regimen, patients could then self-manage the procedure at home using the remaining dose. ACOG found this risk and evaluation mitigation strategy (REMS) unnecessary and urged the FDA to remove this requirement in order to broaden access.4 The following year, as pandemic-era telemedicine flourished and the Supreme Court heard Dobbs—a case that was widely expected to challenge if not overthrow core tenets of Roe v. Wade—access to medication abortion was significantly expanded. In December 2021, the FDA moved to permanently allow access to mifepristone by mail.5 As ACOG had suggested, the agency altered its REMS Program for the drug, removing the “in-person dispensing requirement,” thus allowing for greater autonomy in self-management.6 In March, JAMA Internal Medicine reported new data showing that pandemic-era data collections proved that a physical exam was unnecessary prior to prescription of the drug in the overwhelming [End Page 58] majority of situations.7 An editorial in the same issue explicitly called for a new, freer standard in the use of medication abortion, heralding a new consensus emerging among clinicians.8 When the draft of the majority opinion of Dobbs v. Jackson Women’s Health Organization...
