Analysis of uterine rupture at university teaching hospital Pakistan

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.

Survival Status and Predictors of Mortality Among Women with Uterine Rupture at Public Hospitals of Eastern Ethiopia. Semi-Parametric Survival Analysis

Background

Uterine rupture is the most dangerous complication of labor and contributes to high maternal mortality. Despite efforts to improve basic and comprehensive emergency obstetric treatment, women continue to suffer from disastrous maternal outcomes.

Purpose

This study aimed to assess the survival status and predictors of mortality among women with uterine rupture at public hospitals in the Harari Region, Eastern Ethiopia.

Patients and Methods

We conducted a retrospective cohort study among women with uterine rupture in public hospitals in Eastern Ethiopia. All women with uterine rupture were followed for 11 years retrospectively. Statistical analysis was conducted with STATA version 14.2. Kaplan-Meier curves together with a Log rank test were used to estimate the survival time and show the presence of differences among groups. Cox Proportion Hazard (CPH) model was used to determine the association between independent variables and survival status.

Results

There were 57,006 deliveries in the study period. We found that 10.5% (95% CI: 6.8-15.7) of women with uterine rupture have died. The median recovery and death time for women with uterine rupture were 8 and 3 days with interquartile range (IQR) of 7-11 days and 2-5 days, respectively. Antenatal care follow-up (AHR: 4.2, 95% CI: 1.8-9.79), education status (AHR: 0.11; 95% CI: 0.02-0.85), visiting health center (AHR: 4.89; 95% CI: 1.05-22.88), and admission time (AHR: 4.4; 95% CI: 1.89-10.18) were the predictors of survival status of women with uterine rupture.

Conclusion

One out of ten study participants died due to uterine rupture. Factors including not having ANC follow-up, visiting health centers for treatment, and being admitted during the night time were predictors. Thus, a great emphasis has to be given to the prevention of uterine rupture and the linkage within health institutions has to be smooth to improve the survival of patients with uterine rupture with the help of different professionals, health institutions, health bureaus, and policymakers.

Rupture Uterus in a Tertiary Care Centre: A Descriptive Cross-sectional Study

INTRODUCTION

Rupture uterus is an obstetric catastrophe with poor maternal and fetal outcome. The objective of the study is to determine the prevalence of rupture uterus in pregnancy.

METHODS

This was a descriptive cross sectional study conducted in a tertiary care centre from January 2016 to December 2016 after taking ethical approval (Approval No. F-NMC-510/76/77) from Institutional Review Committee. Convenience sampling method was used. Data were entered in the Microsoft Excel sheet and obtained data was analysed using Statistical Package for Social Sciences version 18 software for central tendency and frequencies.

RESULTS

Out of total 1559 deliveries, prevalence of rupture uterus was found to be 12 (0.0077%). Previous lower segment caesarean scar rupture was the most common risk factor noted in 7 (58.3%) cases. A total of seven patients (58.3%) required intensive care unit admission and blood transfusion. Other maternal complications were surgical site infection 2 (16.67%), sepsis 2 (16.67%), paralytic ileus 1 (8.3%), pelvic collection 1 (8.3%) and vesico vaginal fistula 1 (8.3%). Two maternal deaths (16.67%) and perinatal death was noted in 8 (66.66 % ) cases.

CONCLUSIONS

Rupture uterus most commonly occurred in scarred uterus. Identification of high risk pregnancy, judicious caesarean section, proper labor monitoring, early diagnosis and prompt management are essential in reducing its occurrences.

Burden of Uterine Rupture and Its Determinant Factors in Ethiopia: A Systematic Review and Meta-analysis

Background. Uterine rupture is a life-threatening obstetrical emergency, which results in serious undesired maternal and perinatal complications in resource-limited countries, mainly in Ethiopia. The prevalence, determinants, and outcomes of uterine rupture described by different studies were highly inconsistent in Ethiopia. Therefore, this systematic review and meta-analysis is aimed at estimating the pooled prevalence, determinants, and adverse outcomes of uterine rupture in Ethiopia. Methods. Studies were searched from international databases (PubMed/MEDLINE, HINARI, Cochrane library, Google Scholar, and web of science) and Ethiopian universities’ digital libraries (Addis Ababa University, University of Gondar, and Harameya University). All observational studies were included. A total of 15 studies that fulfill the inclusion criteria were included in this meta-analysis. Data were extracted by two reviewers and exported to STATA version 11 for analysis. The $I^2$ statistics were used to assess heterogeneity across the studies. Publication bias was examined by using Egger’s test and funnel plot. The pooled prevalence of uterine rupture and its outcomes were estimated by using a random effects model. The associations between determinants and uterine rupture were evaluated by using both random and fixed-effect models. Results. In this meta-analysis, a total of 15 studies with 92,394 study participants were involved. The pooled prevalence of uterine rupture was 2.37% in Ethiopia. Obstructed labor ( $\text{OR}=3.03$ ; $95\%\text{CI}=2.52,3.63$ ), lack of antenatal care follow-up ( $\text{OR}=5.79$ ; $95\%\text{CI}=2.47,13.61$ ), duration of $\text{labor}>24$ hours ( $\text{OR}=3.75$ ; $95\%\text{CI}=2.24,6.29$ ), grand multipara ( $\text{OR}=10.79$ ; $95\%\text{CI}=4.77,24.40$ ), and being rural residency ( $\text{OR}=7.17$ ; $95\%\text{CI}=3.90,13.16$ ) were significantly associated with uterine rupture. Conclusion. The overall prevalence of uterine rupture was high in Ethiopia. Obstructed labor, lack of antenatal care follow-up, duration of $\text{labor}>24$ hours, grand multipara, and rural residency were determinants of uterine rupture. This study implies the need to develop plans and policies to improve antenatal care follow-up and labor and delivery management at each level of the health system.

Oxytocin and emergency caesarean section in a mediumsized hospital in Pakistan: A cross-sectional study

INTRODUCTION

One of the most common complications during labor is prolonged labor (dystocia), which is associated with risks for the mother and fetus. Dystocia is usually treated with oxytocin, which is also used to induce labor. Oxytocin may not have the desired effect of progress and can negatively affect the fetus, thus resulting in an emergency caesarean section (CS). The aim of this study was to describe obstetric practice, use of oxytocin and its association with an emergency CS.

METHODS

A cross-sectional retrospective register study was conducted that included all women who gave birth during 2014 and 2015 at a hospital in a large city in Pakistan.

RESULTS

A total of 6652 women gave birth to 6767 newborns, 66.8% were multiparous and 33.2% primiparous women. Of the primiparous women, 78.9% had a spontaneous vaginal birth, 1.2% an elective CS and 14.4% an emergency CS. Of the multiparous women, 81.9% had a spontaneous vaginal birth, 8.0% an elective CS and 6.7% an emergency CS. Operative vaginal birth was 2.1% among primiparous and 0.2% among multiparous women. Oxytocin for induction or augmentation was administered to 60.0% of primiparous and 30.5% of multiparous women. Oxytocin during the first stage of labor was associated with an increased risk for emergency CS for both primiparous and multiparous women.

CONCLUSIONS

Despite the association between oxytocin and emergency CS, the CS rate was low in this hospital. The majority of the women gave birth vaginally, even with a breech presentation. Few operative vaginal births were performed.

Outcome of uterine rupture and associated factors in Yirgalem general and teaching hospital, southern Ethiopia: a cross-sectional study

Background

The occurrence of uterine rupture has dropped significantly in high income countries. It continues, however, to be a major public and clinical health problem in low income countries including Ethiopia. Aim of this study was to assess management outcomes of uterine rupture and associated factors in Yirgalem General and Teaching Hospital in South Ethiopia.

Methods

Institution-based cross-sectional study was conducted to examine medical records of women with uterine rupture between January 1, 2012, and Decem”ber 31, 2017. Data were collected based on a checklist. Descriptive statistics and logistic regression analyses were performed.

Results

Incidence of uterine rupture was 345 in 13,500 live births (25.5 in 1000 live births) in the study period. Of these, 331 cases were included. Poor maternal outcome occurred in 224 (67.7%) women. There were 13 (3.7%) maternal deaths and 320 (96.7%) stillbirths. Wound site infection (131; 39.6%) and anemia (129; 39%) were the most common post-operative complications. Prolonged duration of labor (more than 24 h) (adjusted odds ratio (aOR) 3.6; 95% CI 1.7–7.4), women with sepsis on admission (aOR 2.9; 95% CI 1.4–6.1), hemoglobin level < 7 g/dl prior to surgical intervention (aOR 4.5; 95% CI 1.1–17.8), delayed surgical intervention after hospitalization (4 h or more before surgery) (aOR 3.8; 95% CI 1.8–8), women who did not receive blood transfusion (aOR 4.0; 95% CI 2.1–7.9) and prolonged intraoperative time (aOR 5.5; 95% CI 2.8–10.8) were all factors associated with poor maternal outcome of uterine rupture.

Conclusion

Poor maternal outcome of uterine rupture was high in the study area as compared to other studies. Proper management of anemia, prompt surgical treatment, proper labor progress monitoring, surgical skills, improved infection prevention, maximizing blood transfusion availability and improving the quality of maternal healthcare all play a significant role in reducing uterine rupture and enhancing the chance of good outcomes.

Incidence and factors associated with outcomes of uterine rupture among women delivered at Felegehiwot referral hospital, Bahir Dar, Ethiopia: cross sectional study

Background

Maternal mortality is a major public health challenge in Ethiopia. Uterine rupture is an obstetrical emergency with serious undesired complications for laboring mothers resulting in fatal maternal and neonatal outcomes. Uterine rupture has been contributing to high maternal morbidity and mortality. However, there is limited research on the factors and management outcomes of women with uterine rupture. Understanding the factors and management outcomes might delineate strategies to support survivors. Therefore the aim of this study is to assess the incidence and factors associated with outcomes of uterine rupture among laboring mothers at Felegehiwot Referral Hospital in Bahir Dar City, Northwest Ethiopia.

Methods

This is a cross sectional study with retrospective facility based data collection technique. All pregnant women who were managed for ruptured uterus at Felegehiwot referral hospital from September 11 2012 to August 30 2017 were included. The chart numbers of the women collected from operation theatre registers. Their case folders retrieved from the medical records room for analysis. Using structured check list, information on their sociodemography, booking status, clinical features at presentation and the place of attempted vaginal delivery was extracted. Data on the intraoperative findings, treatment, and associated complications and outcomes also collected. The collected data cleaned, coded and entered into EPI- Info version (7.1.2.0) and then exported in to SPSS Version 20.0 for analysis. Statistical comparison was done using chi square (X²). Strength of association between the explanatory variables and outcome variables described using odds ratio at 95% CI and P value less than 0.05. The results presented in tables.

Results

We studied 239 cases of uterine rupture in the 5 years period. Mothers without previous cesarean delivery including eight primigravidas took 87% of the cases. From all study participants, 54 of mothers (22.6%) developed undesired outcomes whereas 185(77.4%) discharged without major sequel. More than half (56.9%) arrived in hypovolemic shock. Total abdominal hysterectomy was the commonest procedure accounting for 61.5%. Duration of surgery was less than 2 h in 67.8% of the procedures. Anemia is the commonest complication (80.3%) followed by wound infection and VVF (11.7% each). There were 5 maternal deaths (2.1%). Mothers who had prolonged operation time (> 2 h) (AOR: 2.2, 95% CI: 1.10, 4.63) were significantly associated with undesired maternal outcomes after management of uterine rupture.

Conclusion

Incidence of ruptured uterus and its complications were high in the study area. It reflects the need for improvement in obstetric care and strong collaboration with referring health facilities to ensure prompt referral and management.

Evaluation of obstetricians' surgical decision making in the management of uterine rupture

Background

Uterine rupture is an obstetric calamity with surgery as its management mainstay. Uterine repair without tubal ligation leaves a uterus that is more prone to repeat rupture while uterine repair with bilateral tubal ligation (BTL) or (sub)total hysterectomy predispose survivors to psychosocial problems like marital disharmony.

This study aims to evaluate obstetricians’ perspectives on surgical decision making in managing uterine rupture.

Methods

A questionnaire-based cross-sectional study of obstetricians at the 46th annual scientific conference of Society of Gynaecology and Obstetrics of Nigeria in 2012. Data was analysed by descriptive and inferential statistics.

Results

Seventy-nine out of 110 obstetricians (71.8%) responded to the survey, of which 42 (53.2%) were consultants, 60 (75.9%) practised in government hospitals and 67 (84.8%) in urban hospitals, and all respondents managed women with uterine rupture. Previous cesarean scars and injudicious use of oxytocic are the commonest predisposing causes, and uterine rupture carries very high incidences of maternal and perinatal mortality and morbidity. Uterine repair only was commonly performed by 38 (48.1%) and uterine repair with BTL or (sub) total hysterectomy by 41 (51.9%) respondents. Surgical management is guided mainly by patients’ conditions and obstetricians’ surgical skills.

Conclusion

Obstetricians’ distribution in Nigeria leaves rural settings starved of specialist for obstetric emergencies. Caesarean scars are now a rising cause of ruptures. The surgical management of uterine rupture and obstetricians’ surgical preferences vary and are case scenario-dependent. Equitable redistribution of obstetricians and deployment of medical doctors to secondary hospitals in rural settings will make obstetric care more readily available and may reduce the prevalence and improve the outcome of uterine rupture. Obstetrician’s surgical decision-making should be guided by the prevailing case scenario and the ultimate aim should be to avert fatality and reduce morbidity.
