Posterior Reversible Encephalopathy Syndrome in a Late Postpartum Patient With a Rare Complication of Subarachnoid Hemorrhage.

Posterior reversible encephalopathy syndrome (PRES) is considered a neuroclinical syndrome of headache, confusion, visual changes, and seizures associated with neuroimaging findings of posterior cerebral white matter edema. Although the incidence of the syndrome is largely unknown, this condition is becoming increasingly recognized. The prognosis is generally good with most symptoms resolving within one week and lesions on imaging resolving in two weeks. Death and significant neurological disability have been reported but are relatively rare. In this report, we present a 10-day postpartum patient with an atypical history of headache and seizure-like activity. Neuroimaging revealed findings consistent with PRES as well as a rare complication of subarachnoid hemorrhage. This case highlights the importance of clinicians considering preeclampsia/eclampsia-induced PRES when encountering a postpartum patient with headache and hypertension to further reduce morbidity and mortality in this patient population.

Exploring the Utility of remimazolam in cesarean sections under general anesthesia: A preliminary retrospective analysis and Implications for future study.

Background: Remimazolam has recently been introduced as a maintenance agent for general anesthesia. However, the effect of remimazolam on peripartum prognosis has not been reported. Therefore, this study aimed to compare the effects of remimazolam and propofol for uterotonic drugs following cesarean section. Methods: The electronic medical records of 51 adult women who underwent elective cesarean sections by single obstetrician under general anesthesia were collected. Participants were categorized into two groups: the propofol group and the remimazolam group. General anesthesia was maintained by continuous infusion of propofol or remimazolam after delivery. The number of uterotonic drugs administered during the cesarean section, the estimated blood loss (EBL), and length of hospital stay (LOS) after delivery were assessed. Results: Of the 51 patients included in the study, 35 were in the propofol group and 16 in the remimazolam group. In the remimazolam group, five patients (31.3%, 5/16) received more uterotonics than the standard regimen. Conversely, in the propofol group, 19 patients (54.3%, 19/35) were injected with more uterotonics than the standard regimen. Logistic regression analysis showed that abnormal positioning of the placenta (P = 0.079) and not using remimazolam (P = 0.100) were the most relevant factors associated with the increased use of uterotonics. There was no significant difference in EBL between the two groups. The use of remimazolam was clinically relevant with a shorter LOS (P = 0.059). Conclusions: The use of remimazolam as a maintenance agent did not result in significantly higher use of intrapartum uterotonics compared to the use of propofol. These results cannot exclude all adverse effects of remimazolam during cesarean delivery. Further randomized controlled trials must be conducted to obtain high-quality evidence.

Prognosis of subsequent pregnancy in uterine necrosis after uterine artery embolization.

In an 8-year period at two medical center, 138 patients underwent uterine artery embolization, and 11 of them were diagnosed with uterine necrosis. Among them, three were successfully conceived. However, one of them developed an arteriovenous malformation after an artificial abortion, and another experienced complications, including placenta previa and placenta accreta spectrum, which resulted in early preterm delivery and recurrent postpartum hemorrhage, necessitating subtotal hysterectomy. Therefore, it is crucial to prepare for potential adverse pregnancy outcomes in subsequent pregnancies for patients with a history of uterine necrosis.

Evidence-based Cesarean Delivery: Preoperative Management (Part 7).

The preoperative preparation for cesarean delivery is a multistep approach for which protocols should exist at each hospital system. These protocols should be guided by the findings of this review. The interventions reviewed and recommendations made for this review have a common goal of decreasing maternal and neonatal morbidity and mortality related to cesarean delivery (CD). The preoperative time period starts prior to the patient's arrival to the hospital and ends immediately prior to skin incision. Skin cleansing in addition to CDC recommendations of showering with either soap or an antiseptic solution at least the night prior to a procedure has not been shown to further decrease rates of infection. Hair removal at the cesarean skin incision is not necessary, however if preferred by the surgical team then clipping or depilatory creams should be used rather than shaving. Preoperative enema is not recommended. A clear liquid diet may be ingested up to 2 hours prior and a light meal up to 6 hours prior to CD. Consider giving a preoperative carbohydrate drink to non-diabetic patients up to 2 hours prior to planned CD. Weight-based intravenous (IV) cefazolin is recommended 60 minutes prior to skin incision: 1-2g IV for patients without obesity and 2g for patients with obesity or weight ≥ 80kg. Adjunctive azithromycin 500mg IV is recommended for patients with labor or rupture of membranes. Preoperative gabapentin can be considered as may decrease pain scores with movement in the postoperative period. Tranexamic acid (1g in 10-20mL of saline or 10mg/kg IV) is recommended prophylactically for patients at high-risk of postpartum hemorrhage, and can be considered in all patients. Routine use of mechanical venous thromboembolism prophylaxis is recommended preoperatively and is to be continued until the patient is ambulatory. Music, active warming of the patient, and adequate operating room temperature improves outcomes for the patient and neonate, respectively. Noise levels should allow clear communication between teams, however a specific decibel level has not been defined in the data. Patient positioning with left lateral tilt decreases hypotensive episodes compared to right lateral tilt, which is not recommended. Manual displacers result in fewer hypotensive episodes than left lateral tilt. Both vaginal and skin preparation should be performed with either chlorhexidine (preferred) or povidone-iodine. Placement of an indwelling urinary catheter is not necessary. Non-adhesive drapes are recommended. Cell salvage, while effective for high-risk patients, is not recommended for routine use. Maternal supplemental oxygen does not improve outcomes. A surgical safety checklist (including a timeout) is recommended for all CDs.

Clinical Analysis of Risk Factors and Perinatal Outcomes in Recurrent Pre-Eclampsia with Severe Features.

To analyze the differences in risk factors and pregnancy outcomes between recurrent and initial pre-eclampsia(PE) with severe features. Data from recurrent (n = 128) and initial (n = 904) PE with severe features who terminated their pregnancy or gave birth at 20 weeks of gestation or later at the tertiary teaching hospital (Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital) from January 2016 to December 2022 were collected. Risk factors for recurrent PE with severe features and differences in pregnancy outcomes between the two groups were assessed using the chi-square test, student t-test, or nonparametric test. Independent risk factors for recurrent PE with severe features were further analyzed by logistic regression. (1) Logistic regression analysis identified 3 independent risk factors for recurrent PE with severe features: history of cesarean section, rural residence and chronic hypertension. In addition, assisted reproductive technology (ART) is an independent risk factor for initial PE with severe features; (2) The incidence of oligohydramnios, chorioamnionitis, preterm birth, stillbirth, fetal growth restriction (FGR) and abnormal umbilical blood flow was higher in the recurrent PE with severe features group than in the initial PE with severe features group(P < 0.05). In contrast, the incidence of premature rupture of membrane (PROM) and postpartum hemorrhage (PPH) was higher in the group of initial PE with severe features(P < 0.05); (3) In the recurrent PE with severe features group, gestational age(GA) of birth and birth weight were lower than those in the initial PE with severe features group(P < 0.05). Also, the incidence of mild asphyxia, the rate of neonatal intensive care unit (NICU) hospitalization, length of stay in NICU, and the rate of abandoning treatment in the recurrent PE with severe features group were higher than those in the initial PE with severe features group(P < 0.05). 3 independent risk factors was identified for recurrent PE with severe features: history of cesarean section, rural residence and chronic hypertension. Women with recurrent PE with severe features are more likely to have adverse perinatal outcomes than those with initial PE with severe features.

The virtual reality classroom: a randomized control trial of medical student knowledge of postpartum hemorrhage emergency management.

Objective: To investigate the use of a virtual reality learning environment (VRLE) to enhance medical student knowledge of postpartum hemorrhage (PPH) emergency management and insertion of a postpartum balloon. Methods: A randomized control trial involving medical students from University College Dublin, Ireland. Participants were randomly allocated to the intervention group (VRLE tutorial) or control group (PowerPoint tutorial on the same topic). All participants completed pre-learning experience and post-learning experience surveys. Both groups were timed and assessed on postpartum balloon insertion technique on a model pelvis. The primary outcome was assessment of student knowledge. Secondary outcomes included confidence levels, time taken to complete the task, technique assessment, satisfaction with the learning environment, and side effects of VR. Results: Both learning experiences significantly (p < 0.001) enhanced student performance on the post-learning experience multiple choice questionnaire, with no difference between the intervention and control groups. In the intervention group, time for task completion was significantly less compared to the control group (1-2 min vs. 2-3 min, p = 0.039). Both learning experiences significantly (p < 0.001) enhanced student confidence, with no significant difference between intervention and control groups. 100% of the students using the VRLE enjoyed the experience, and 82.4% were very likely to recommend use of VRLE in medical education. 94.1% of the students felt the VRLE was beneficial over didactic teaching. Conclusion: Receiving formal instruction, regardless of format, enhances students' knowledge and confidence of the topic covered. Students who received instruction via the VRLE assembled the postpartum balloon faster than students who received didactic teaching. VR may be beneficial in teaching hands-on procedural skills in obstetrics and gynecology education.

Characteristics and treatment for severe postpartum haemorrhage in different midwifery hospitals in one district of Beijing in China: an institution-based, retrospective cohort study.

OBJECTIVE: To identify the characteristics and treatment approaches for patients with severe postpartum haemorrhage (SPPH) in various midwifery institutions in one district in Beijing, especially those without identifiable antenatal PPH high-risk factors, to improve regional SPPH rescue capacity. DESIGN: Retrospective cohort study. SETTING: This study was conducted at 9 tertiary-level hospitals and 10 secondary-level hospitals in Haidian district of Beijing from January 2019 to December 2022. PARTICIPANTS: The major inclusion criterion was SPPH with blood loss ≥1500 mL or needing a packed blood product transfusion ≥1000 mL within 24 hours after birth. A total of 324 mothers with SPPH were reported to the Regional Obstetric Quality Control Office from 19 midwifery hospitals. OUTCOME MEASURES: The pregnancy characteristics collected included age at delivery, gestational weeks at delivery, height, parity, delivery mode, antenatal PPH high-risk factors, aetiology of PPH, bleeding amount, PPH complications, transfusion volume and PPH management. SPPH characteristics were compared between two levels of midwifery hospitals and their association with antenatal PPH high-risk factors was determined. RESULTS: SPPH was observed in 324 mothers out of 106 697 mothers in the 4 years. There were 74.4% and 23.9% cases of SPPH without detectable antenatal PPH high-risk factors in secondary and tertiary midwifery hospitals, respectively. Primary uterine atony was the leading cause of SPPH in secondary midwifery hospitals, whereas placental-associated disorders were the leading causes in tertiary institutions. Rates of red blood cell transfusion over 10 units, unscheduled returns to the operating room and adverse PPH complications were higher in patients without antenatal PPH high-risk factors. Secondary hospitals had significantly higher rates of trauma compared with tertiary institutions. CONCLUSION: Examining SPPH cases at various institutional levels offers a more comprehensive view of regional SPPH management and enhances targeted training in this area.

Uterine arteriovenous malformation: a case of challenges in diagnosis and management of a patient with a history of misdiagnosed hemorrhage.

Introduction: Uterine arteriovenous malformations (AVMs) are a rare cause of obstetrical hemorrhage. It can be congenital due to a defect during embryogenesis or acquired. Uterine AVMs can cause life threatening postpartum hemorrhage, and is most frequently misdiagnosed. This case highlights the diagnostic challenges posed by uterine arteriovenous malformation, a rare vascular anomaly that poses significant challenges in diagnosis and management. Case presentation: This case report details the clinical presentation, diagnostic challenges, and treatment approach for a 39-year-old woman. In the absence of a medical history indicative of pre-existing ailments, the individual in question has undergone two emergency cesarean sections as documented in her surgical history, in addition to two previous dilation and curettage D&C operations. The patient presented with heavy vaginal bleeding 6 months after a cesarean section. The patient's clinical presentation, imaging findings, and intraoperative observations collectively substantiate the diagnosis of uterine AVMs. Discussion: Women who have had uterine instrumentatio surgery, such as a cesarean section or dilatation and curettage (D&C) are more likely to develop acquired uterine AVMs. The absence of uterine artery embolism options compelled the use of alternative diagnostic methods, including contrast MRI, which successfully detected abnormal vascular lesions. The choice for hysterectomy was influenced by the patient's completion of childbearing and the presence of large vessels in proximity to critical regions. Conclusion: This case emphasizes the significance of adapting treatment plans based on local resource constraints and the need for ongoing efforts to enhance diagnostic capabilities in undeserved regions.

Induction of labor in term pregnancies with isolated polyhydramnios: Is it beneficial or harmful?

OBJECTIVE: To compare rates of adverse pregnancy outcomes in term pregnancies complicated by polyhydramnios between women who had induction of labor (IOB) versus women who had expectant management. METHODS: This multicenter retrospective study included term pregnancies complicated by isolated polyhydramnios. Patients who underwent IOB were compared with those who had expectant management. The primary outcome was defined as a composite adverse maternal outcome, and secondary outcomes were various maternal and neonatal adverse outcomes. Univariate analyses were followed by multivariate logistic regression. RESULTS: A total of 865 pregnancies with term isolated polyhydramnios were included: 169 patients underwent IOB (19.5%), while 696 had expectant management and developed spontaneous onset of labor (80.5%). Women who underwent IOB had significantly higher rates of composite adverse maternal outcome (23.1% vs 9.8%, P < 0.01), prolonged hospital stay, perineal tear grade 3/4, intrapartum cesarean, postpartum hemorrhage, blood products transfusion, and neonatal asphyxia compared with expectant management. While the perinatal fetal death rate was similar between the groups (0.6% vs 0.6%, P = 0.98), the timing of the loss was different. Four women in the expectant management group had a stillbirth, while in the induction group one case of intrapartum fetal death occurred due to uterine rupture. Multivariate analyses revealed that IOB was associated with a higher rate of composite adverse maternal outcome (adjusted odds ratio, 2.22 [95% CI, 1.28-3.83]; P < 0.01). CONCLUSION: IOB in women with term isolated polyhydramnios is associated with higher rates of adverse maternal outcomes in comparison to expectant management. Further research is needed to determine the optimal approach for the management of isolated polyhydramnios at term.

Causal associations between Helicobacter pylori infection and pregnancy and neonatal outcomes: a two-sample Mendelian randomization study.

Background: Observational studies have reported that Helicobacter pylori (H. pylori) infection is associated with a series of pregnancy and neonatal outcomes. However, the results have been inconsistent, and the causal effect is unknown. Methods: A two-sample Mendelian randomization (MR) study was performed using summary-level statistics for anti-H. pylori IgG levels from the Avon Longitudinal Study of Parents and Children Cohort. Outcome data for pregnancy (miscarriage, preeclampsia-eclampsia, gestational diabetes mellitus, placental abruption, premature rupture of membranes, postpartum hemorrhage) and neonates (birthweight, gestational age, and preterm birth) were sourced from genome-wide association meta-analysis as well as the FinnGen and Early Growth Genetics Consortium. Causal estimates were calculated by five methods including inverse variance weighted (IVW). The heterogeneity of instrumental variables was quantified by Cochran's Q test, while sensitivity analyses were performed via MR-Egger, MR-PRESSO, and leave-one-out tests. Results: IVW estimates suggested that genetically predicted anti-H. pylori IgG levels were significantly associated with increased risks of preeclampsia-eclampsia (odds ratio [OR] = 1.12, 95% confidence interval [CI] 1.01-1.24, P = 0.026) and premature rupture of membranes (OR = 1.17, 95% CI 1.05-1.30, P = 0.004). Similar results were obtained for preeclampsia-eclampsia from the MR-Egger method (OR = 1.32, 95% CI 1.06-1.64, P = 0.027) and for premature rupture of membranes from the weighted median method (OR = 1.22, 95% CI 1.06-1.41, P = 0.006). No significant causal effects were found for other outcomes. There was no obvious heterogeneity and horizontal pleiotropy across the MR analysis. Conclusion: Our two-sample MR study demonstrated a causal relationship of H. pylori infection with preeclampsia-eclampsia and premature rupture of membranes. The findings confirm the epidemiological evidence on the adverse impact of H. pylori in pregnancy. Further studies are needed to elucidate the pathophysiological mechanisms and assess the effectiveness of pre-pregnancy screening and preventive eradication.

Maternal mortality review in a major tertiary referral hospital in Liberia, 2018-2021.

Objectives: Anecdotal evidence showed increased maternal deaths at the major tertiary hospital over the past two years (2020-2021). We reviewed the maternal death audit data, identified the main causes of maternal death, and associated risk factors. Findings were shared with policymakers to help reduce maternal mortality. Study design: We conducted a secondary data review and descriptive analysis of maternal death at the tertiary hospital located in Monrovia. Method: The maternal death data were extracted from patient medical records, including death certificates and maternal audit records. The record of live births was obtained from the delivery register. Data were analyzed using Epi Info version 7.2 Maternal mortality ratio (MMR) was estimated, the leading direct and indirect causes of maternal death were identified, and the factors associated with maternal death were explored using logistic regression at a 5% level of significance. Results: There are a total of 233 maternal deaths and 14, 879 live births giving a maternal mortality ratio (MMR) of 1565 per 100,000 live births during the period under review. The median age of the mothers at death was 29 (14-45) years. About 40.3% (94/233) of cases died within <1 day of admission, referrals accounted for 59% (137/233) of the cases. Direct causes of death accounted for 66% (147/223). Hemorrhage [30.6% (45/147)], Eclampsia [(30/147) 20.6%] and Sepsis [(30/147) 20.6%] were the main direct causes of death while cardiovascular-related [18.4% (14/76)] and HIV/AIDS [16% (12/76)] were the leading indirect cause of death. Patients from referred other facilities were 7.9 times more likely to die as compared to non-referral (pOR:7.9, 95%CI: 5.9-10.6, p < 0.001). Conclusion: The maternal mortality ratio remained high. Referrals were done late. The Liberia Ministry of Health should equip more secondary-level health facilities and tertiary hospitals to handle maternal emergencies and sensitize the populace and healthcare workers on prompt identification and referral of obstetric emergencies. The MoH also needs to improve the blood transfusion services to help in the management of postpartum hemorrhage.

Amniotic Fluid Embolism Coagulopathy Guided by the Point-of-Care Quantra QStat® Hemostasis System: A Case Report.

Amniotic fluid embolism (AFE) is a rare pregnancy complication associated with high maternal mortality that occurs during labor or in the early postpartum period. The diagnosis of AFE is challenging because signs and symptoms are common to other obstetric complications. Early identification and management of profound coagulopathy associated with AFE is essential to improve patient survival. We present a case of a 31-year-old woman with placenta previa and clinical suspicion of AFE after cesarean section. Immediately after delivery, the parturient presented hypotension, hypoxia, coagulopathy, and severe postpartum hemorrhage. We hereby discuss the role of the most recently developed point-of-care viscoelastic testing device, the Quantra QStat® system (Stago Group Company; HemoSonics LLC, Durham, NC), for early detection of acute obstetric coagulopathy and guided hemostatic treatment.

Risk of Postpartum Hemorrhage in Hypertensive Disorders of Pregnancy: Stratified by Severity.

We aimed to determine the composite maternal hemorrhagic outcome (CMHO) among individuals with and without HDP, stratified by disease severity. Additionally, we investigated the composite neonatal adverse outcome (CNAO) among individuals with HDP who had versus did not have PPH. Our retrospective cohort study included all singletons who delivered at a Level IV center over two consecutive years. The primary outcome was the rate of CMHO, defined as blood loss ≥ 1000 mL, use of uterotonics, mechanical tamponade, surgical techniques for atony, transfusion, venous thromboembolism, ICU admission, hysterectomy, or maternal death. A subgroup analysis was performed to investigate the primary outcome stratified by 1) cHTN, 2) gHTN and preeclampsia without severe features, and 3) preeclampsia with severe features. A multivariable regression analysis was performed to investigate the association of HDP with and without PPH on a CNAO which included APGAR <7 at 5min, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, seizures, neonatal sepsis, meconium aspiration syndrome, ventilation > 6 hours, hypoxic-ischemic encephalopathy or neonatal death. Of 8,357 singletons, 2,827 (34%) had HDP. Preterm delivery <37 weeks, induction of labor, prolonged oxytocin use, and MgSO4 usage were more common in those with versus without HDP (p<0.001). CMHO was higher among individuals with HDP than those without HDP (26% vs.19%; aRR 1.11, 95% CI 1.01-1.22). In the subgroup analysis, only individuals with preeclampsia with severe features were associated with higher CMHO (n=802; aRR 1.52, 95% CI 1.32-1.75). There was a higher likelihood of CNAO in individuals with both HDP and PPH compared to those with HDP without PPH (aRR 1.49, 95% CI 1.06-2.09). CMHO was higher among those with HDP. After stratification, only those with preeclampsia with severe features had an increased risk of CMHO. Among individuals with HDP, those who also had a PPH had worse neonatal outcomes than those without hemorr.

Risk Factors of Patients with Postpartum Acute Kidney Injury: An Observational Study.

Postpartum acute kidney injury (AKI) is a condition characterized by a sudden and rapid decline in kidney function that occurs shortly after childbirth. Several risk factors may be associated with postpartum acute kidney injury (AKI). Understanding the possible risk factors is essential for timely intervention and improved maternal healthcare. The aim of the study was to assess the risk factors of postpartum acute kidney injury patients. This prospective observational study took place at Mymensingh Medical College Hospital, from March 2020 to April 2021. It was carried out in the Departments of Nephrology and Departments of Obstetrics & Gynecology, where 153 postpartum acute kidney injury (AKI) patients were enrolled through purposive sampling. The study collected data on patient demographics, etiology and presentation. Statistical analysis was conducted using SPSS (Statistical Package for the Social Sciences) version 26.0, with a significance threshold set at p<0.05 for all tests. Among participants, puerperal sepsis (77.8%) and toxemia of pregnancy (58.8%) were prevalent risk factors. Intrauterine death was rare (1.3%). Other risk factors such as postpartum hemorrhage 22.2%, HELLP syndrome 11.1%, and antepartum hemorrhage 15.0% were found. A statistically significant difference in postpartum hemorrhage prevalence (p=0.038) was noted between hemodialysis and non-hemodialysis patients. Puerperal sepsis is the most common risk factor for postpartum acute kidney injury, closely followed by toxemia of pregnancy. Intrauterine death is rare, while postpartum hemorrhage significantly affects subjects, with variations noted between hemodialysis and non-hemodialysis patients.

Relationship between the natural cessation time of umbilical cord pulsation in full-term newborns delivered vaginally and maternal-neonatal outcomes: a prospective cohort study.

BACKGROUND: To analyze the impact of the time of natural cessation of the umbilical cord on maternal and infant outcomes in order to explore the time of clamping that would be beneficial to maternal and infant outcomes. METHODS: The study was a cohort study and pregnant women who met the inclusion and exclusion criteria at the Obstetrics and Gynecology Department of Qilu Hospital of Shandong University from September 2020 to September 2021. Analysis using Kruskal-Wallis rank sum test, Pearson's Chi-squared test, generalized linear mixed model (GLMM) and repeated measures ANOVA. If the difference between groups was statistically significant, the Bonferroni test was then performed. A two-sided test of P < 0.05 was considered statistically significant. RESULTS: A total of 345 pregnants were included in this study. The subjects were divided into the ≤60 seconds group (n = 134), the 61-89 seconds group (n = 106) and the ≥90 seconds group (n = 105) according to the time of natural arrest of the umbilical cord. There was no statistically significant difference in the amount of postpartum hemorrhage and the need for iron, medication, or supplements in the postpartum period between the different cord spontaneous arrest time groups for mothers (P > 0.05). The weight of the newborns in the three groups was (3316.27 ± 356.70) g, (3387.26 ± 379.20) g, and (3455.52 ± 363.78) g, respectively, and the number of days of cord detachment was 12.00 (8.00, 15.75) days, 10.00 (7.00, 15.00) days and 9.00 (7.00, 13.00) days, respectively, as the time of natural cessation of the cord increased. The neonatal lymphocyte ratio, erythrocyte pressure, and hemoglobin reached a maximum in the 61-89 s group at (7.41 ± 2.16) %, (61.77 ± 8.17) % and (194.52 ± 25.84) g/L, respectively. Lower incidence of neonatal hyperbilirubinemia in the 61-89 s group compared to the ≥90s group 0 vs 4.8 (P < 0.05). CONCLUSIONS: In full-term singleton vaginal births, maternal and infant outcomes are better when waiting for 61-89 s after birth for the cord to stop pulsating naturally, suggesting that we can wait up to 90s for the cord to stop pulsating naturally, and if the cord does not stop pulsating after 90s, artificial weaning may be more beneficial to maternal and infant outcomes.

Clinical analysis of complete uterine rupture during pregnancy.

BACKGROUND: Uterine rupture in pregnant women can lead to serious adverse outcomes. This study aimed to explore the clinical characteristics, treatment, and prognosis of patients with complete uterine rupture. METHODS: Data from 33 cases of surgically confirmed complete uterine rupture at Chenzhou No.1 People's Hospital between January 2015 and December 2022 were analyzed retrospectively. RESULTS: In total, 31,555 pregnant women delivered in our hospital during the study period. Of these, approximately 1‰ (n = 33) had complete uterine rupture. The average gestational age at complete uterine rupture was 31+4 weeks (13+1-40+3 weeks), and the average bleeding volume was 1896.97 ml (200-6000 ml). Twenty-six patients (78.79%) had undergone more than two deliveries. Twenty-five women (75.76%) experienced uterine rupture after a cesarean section, two (6.06%) after fallopian tube surgery, one (3.03%) after laparoscopic cervical cerclage, and one (3.03%) after wedge resection of the uterine horn, and Fifteen women (45.45%) presented with uterine rupture at the original cesarean section incision scar. Thirteen patients (39.39%) were transferred to our hospital after their initial diagnosis. Seven patients (21.21%) had no obvious symptoms, and only four patients (12.12%) had typical persistent lower abdominal pain. There were 13 cases (39.39%, including eight cases ≥ 28 weeks old) of fetal death in utero and two cases (6.06%, both full term) of severe neonatal asphyxia. The rates of postpartum hemorrhage, blood transfusion, hysterectomy were 66.67%, 63.64%, and 21.21%. Maternal death occurred in one case (3.03%). CONCLUSIONS: The site of the uterine rupture was random, and was often located at the weakest point of the uterus. There is no effective means for detecting or predicting the weakest point of the uterus. Rapid recognition is key to the treatment of uterine rupture.

Labor Induction in Women with Isolated Polyhydramnios at Term: A Multicenter Retrospective Cohort Analysis.

Background: With the increasing popularity of elective induction after 39 + 0 weeks, the question of whether induction of labor (IOL) is safe in women with isolated polyhydramnios has become more relevant. We aimed to evaluate the pregnancy outcomes associated with IOL among women with and without isolated polyhydramnios. Methods: This was a multicenter retrospective cohort that included women who underwent induction of labor at term. The study compared women who underwent IOL due to isolated polyhydramnios to low-risk women who underwent elective IOL due to gestational age only. The main outcome measure was a composite adverse maternal outcome, while the secondary outcomes included maternal and neonatal adverse pregnancy outcomes. Results: During the study period, 1004 women underwent IOL at term and met inclusion and exclusion criteria; 162 had isolated polyhydramnios, and 842 had a normal amount of amniotic fluid. Women who had isolated polyhydramnios had higher rates of the composite adverse maternal outcome (28.7% vs. 20.4%, p = 0.02), prolonged hospital stay, perineal tear grade 3/4, postpartum hemorrhage, and neonatal hypoglycemia. Multivariate analyses revealed that among women with IOL, polyhydramnios was significantly associated with adverse composite maternal outcome [aOR 1.98 (1.27-3.10), p < 0.01]. Conclusions: IOL in women with isolated polyhydramnios at term was associated with worse perinatal outcomes compared to low-risk women who underwent elective IOL. Our findings suggest that the management of women with polyhydramnios cannot be extrapolated from studies of low-risk populations and that clinical decision-making should take into account the individual patient's risk factors and preferences.

Implementing a Bundle for Evidence-based Cesarean Delivery May Not Be As Beneficial as Expected: A Multi-center, Pre- and Post- Study.

BACKGROUND: Standardization of procedures improves outcomes. Though systematic reviews have summarized the evidence-based steps (EBS) of cesarean delivery (CD), their bundled implementation has not been investigated. OBJECTIVE: In this pre- and post-implementation trial, we sought to ascertain if bundled EBS of CD, compared to surgeon's preference, improves outcomes. STUDY DESIGN: A StaRI (Standards for Reporting Implementation Studies) compliant, multi-center pre- and post-implementation trial at 4 teaching hospitals was conducted. The pre-implementation period consisted of CD done based on the physicians' preferences for 3 months; educational intervention (e.g., didactics, badge cards, posters, video) occurred at the 4th month. CDs in post-implementation period employed the bundled EBS. A pre-planned 10% randomized audit of both groups assessed adherence and uptake of EBS. The primary outcome was a composite maternal morbidity (CMM), which included estimated blood loss > 1,000 mL, blood transfusion, endometritis, post-partum fever, wound complications, sepsis, thrombosis, ICU admission, hysterectomy, or death. The secondary outcome was a composite neonatal morbidity (CNM) and some of its components were 5-min Apgar score < 7, positive pressure oxygen use, hypoglycemia, or sepsis. A priori Bayesian sample size calculation indicated 700 CD in each group was needed to demonstrate 20% relative reduction (from 15% to 12%) of CMM with 75% certainty. Bayesian logistic regression with neutral priors was used to calculate likelihood of net-improvement in adjusted relative risk (aRR) with 95% credible intervals (CrI). RESULTS: A total of 1,425 consecutive CD (721 in pre- and 704 in post-implementation group) were examined. Audited data indicated that the baseline EBS utilization rate during the pre-implementation period was 79%; after the implementation bundled EBS of CD the audited adherence was 89%-an uptake of 10.0% of the EBS. In four aspects, the maternal characteristics differed significantly in the pre- and post-implementation periods: race/ethnicity, hypertensive disorder, and the relative contribution of the 4 centers to the cohorts and the gestational age at delivery, but the indications for CD and whether its duration was < versus > 60 min did not. The rates of CMM in the pre- and post-implementation groups were 26% and 22%, respectively (aRR, 0.88; 95% CrI, 0.73-1.04), with a 94 % Bayesian probability of a reduction in CMM. The CNM occurred in 37% of the pre- and in 41% of the post-implementation group (aRR, 1.12; 95% CrI 0.98-1.39), with a 95% Bayesian probability of worsening in CNM. When CMM were segregated by preterm (<37 wks) and term (> 37 weeks) CD, the improvement in maternal outcomes persisted; when CNM were segregated by gestational age subgroupsthe potential for worsening neonatal outcomes persisted as well. CONCLUSIONS: Standardization of the evidence-based bundled steps of cesarean delivery resulted in a modest reduction of the composite maternal outcome; however, a paradoxical increase in neonatal composite morbidity was noted. Although individual evidence-based steps may be of value, while awaiting additional intervention trials a formal bundling of such steps is currently not recommended.

Clinical outcomes and future fertility after uterine artery embolization for postpartum and post-abortion hemorrhage.

BACKGROUND: Postpartum hemorrhage (PPH) and post-abortion hemorrhage (PAH) are life-threatening conditions. PURPOSE: To evaluate the efficacy and safety of uterine arterial embolization (UAE) for PPH and PAH and to investigate future fertility after UAE. MATERIAL AND METHODS: This study included 57 consecutive patients (mean age = 34 years) who underwent UAE for PPH (n = 46) and PAH (n = 11) at our institution between January 2011 and December 2022. Technical success, non-visualization of the peripheral portion of bilateral uterine arteries on angiography, and clinical success, complete hemostasis after UAE, were assessed. UAE-associated complications and factors related to clinical success were analyzed. Pregnancy outcomes after UAE and complications during subsequent pregnancy were investigated in 16 patients who desired fertility and were followed up for >1 year. RESULTS: The technical and clinical success rates were 100% and 84.2%, respectively. Sepsis (n = 1) and uterine empyema (n = 1) were observed as severe complications. Placental disorder, bleeding within 24 h after delivery or abortion, ≥1.5 shock index, ≥6 units of transfusion erythrocytes, and ≥8 obstetrical disseminated intravascular coagulation score were significantly associated with unfavorable clinical outcomes. In total, 16 pregnancies were observed in 12 patients after UAE, three of which were miscarriages and 13 were successful live births. During pregnancy, uterine rupture (n = 1) and accreta (n = 1) were observed. CONCLUSION: UAE is an effective treatment for PPH and PAH. Although UAE could preserve future fertility, careful attention should be paid to perinatal management for unusual complications.

A rare case of fundal intramural ectopic pregnancy associated with previous B-Lynch sutures.

BACKGROUND: Intramural ectopic pregnancy is a rare form of ectopic pregnancy that occurs within the myometrium. It is challenging to diagnose it early because of its nonspecific clinical presentation, and there is no consensus or guideline on the optimal management among gynecologists. CASE PRESENTATION: We report a case of a 34-year-old woman who developed fundal intramural ectopic pregnancy after a previous caesarean section with B-Lynch suture. The B-Lynch suture was performed at 38 weeks of gestation for postpartum hemorrhage caused by refractory uterine atony about 8 years ago. Since then, the patient had oligomenorrhea. The diagnosis of intramural ectopic pregnancy was not confirmed by magnetic resonance imaging or ultrasound. An exploratory laparoscopy and hysteroscopy was performed to remove the gestational sac without significant bleeding. The surgery was successful and the patient recovered well. The patient was advised to monitor her ß-HCG levels regularly until they returned to normal, and a follow-up pelvic ultrasound showed no complications. However, she has not been able to conceive or have an ectopic pregnancy so far. CONCLUSIONS: This case illustrates the difficulty of diagnosing intramural ectopic pregnancy, especially when it is associated with previous uterine surgery and B-Lynch suture. It also demonstrates the feasibility and safety of laparoscopic surgery for treating complete IUP, especially when the gestational sac is located close to the uterine serosa. However, the risk of uterine rupture and hemorrhage should be considered, and the patient should be informed of the possible complications and alternatives. Gynecologists should be familiar with various management strategies and customize the treatment plan according to the patient's clinical situation and preferences.
