Wound infections and other post-operative complications represent a frequent morbidity which may be improved with an understanding of local risk factors. Objective: This project used a retrospective analysis of cesarean section incision complications and infection events along with patient chart information to identify potential risk factors associated with incisional wound complications at our institution. Methods: ICD9 codes identified 618 cesarean sections from July 2012 through June 2013. Of these, 59 were excluded. Twelve different data elements were examined and complications were divided into two categories: presence of infection and presence of seroma/hematoma. Statistics included univariate analysis and multiple logistic regressions to identify an odds ratio for associations using P < 0.05 as significant. Results: 73 (13.1%) of 559 patients developed a post-partum incision complication. Five logistic variables were included in amultiple logistic regression model for all incision complications. Three of the five variables had a significant odds ratio: emergent cesarean section, stapled skin closure, and preeclampsia. Five logistic variables were included in another multiple logistic regression model for all wound infections. Two of the five variables had a significant odds ratio: BMI > 33.4 and preeclampsia. Conclusions: Cesarean section rates account for approximately 30% of deliveries, with significant maternal morbidity associated with incisional wound complications. This study found multiple significant risk factors for both wound complications and infections. Preeclampsia was an independent risk factor for both wound complications and infections.展开更多

In the Saudi context, there is lack of local data to aid decision-making regarding the timing of elective repeat cesarean delivery. Objectives: To estimate the rate of spontaneous onset of labor before the planned gestational age for repeat cesarean section in women who were booked at gestational age of (39 0/7 - 39 6/7) weeks (W39) versus (38 0/7 - 38 6/7) weeks (W38) and to compare the rate of maternal composite outcome between these groups. Design: Retrospective cohort. Setting: This study was conducted at King Abdulaziz Medical City, Jeddah, KSA. Method: Delivery registry books were reviewed to identify all deliveries from 1 January 2014 to 31 December 2016 (3 years). All low-risk pregnant women who had 2 or more cesarean deliveries and who met the inclusion criteria were included. Results: A total of 440 women were included of whom 318 (72.3%) were planned for elective cesarean section at W38 gestational age and 122 women at W39 gestational age. Mothers planned at W39 had higher rate of emergency cesarean deliveries versus those planned at W38 (18.0% versus 10.4%, p = 0.030;RR = 13.06), most frequently due to early onset of contractions (16.4% versus 8.2%, p = 0.012;RR = 12.17) or cervical dilatation (11.6% versus 5.4%, p = 0.024, RR = 16.15). No difference in the incidence of individual or composite maternal complications was noted between the two groups. Mother’s age (OR 0.93, p = 0.018) and schedule date at W39 (OR = 1.94, p = 0.028) were independently associated with spontaneous onset of labor before the scheduled gestational age, while no association was found with parity, previous number of spontaneous vaginal deliveries, number of previous cesarean deliveries or interval from last cesarean delivery. Conclusion: Elective cesarean section scheduled at 39 weeks of gestation or beyond carries a higher risk of emergency cesarean section, with no significant increase in maternal complications. The identification of factors associated with spontaneous onset of labor before the planned gestational age should be carefully identified to determine the optimal timing.展开更多

Induction of labor in women with prior cesarean delivery is an alternative to mitigate the rising cesarean rates. Objectives: To compare the VBAC success rate between two vaginal forms of dinoprostone for labor induction in women with prior cesarean section. Material and Methods: A pilot study was conducted at a large Governmental Hospital, Dhahran, Saudi Arabia, including 200 women with prior cesarean section and planned for labor induction. Participants were randomly allocated into two groups. Group A (n = 100) received dinoprostone 1.5 mg vaginal tablet. Group B (n = 100) received 10 mg dinoprostone sustained release vaginal pessary. Primary outcome was vaginal delivery rate. Secondary outcomes included maternal and neonatal outcomes. Results: The dinoprostone vaginal tablet and dinoprostone vaginal pessary had a comparable vaginal delivery rate (67% and 64%, respectively;p = 0.78). The median patient satisfaction with the birth process was superior in the dinoprostone vaginal pessary group (p = 0.04). Maternal and neonatal outcomes were similar in both groups. Conclusion: Both forms of dinoprostone were effective methods for labor induction in women with prior cesarean section. However, the patient satisfaction with the birth process was in favor of the dinoprostone sustained release vaginal pessary.展开更多

Previous efforts have been exerted in trials to predict the success rates of TOLAC according to specific parameters related to previous cesarean section and before TOLAC. We aimed to investigate the different indications of previous cesarean delivery as independent predictors for successful vaginal birth. Methods: A retrospective study was conducted in Armed Forces Hospitals of the Southern Region between December 15, 2019, and July 1, 2020. The included 566 patients with previous cesarean section who were willing to undergo a trial of labor were divided into two groups according to the success of vaginal birth (VBAC). Results: The nonrecurring indications for previous cesarean delivery were higher in the successful group (fetal distress 54.7% vs 41.1%, malpresentation 26% vs 21.4%, multifetal pregnancy 3.8% vs 2.7%). Additionally, the successful VBAC group had a significantly higher percentage of previous successful VBAC (47.7% vs 21.9%) and prior vaginal deliveries (58.5% vs 44.2%) and less coincidence of medical disorders and meconium-stained liquor (18.1% vs 26.3% and 3.2% vs 8.2%, respectively) than the unsuccessful group. Conclusion: During counseling regarding trial of labor after cesarean section, indications for previous cesarean section not related to arrest of labor can predict higher success of VBAC. Moreover, previous successful vaginal delivery or VBAC improves the success rates.展开更多

Guidelines for Vaginal birth after cesarean (VBAC) indicate that TOLAC offers women with no contraindications and one previous transverse low-segment cesarean. The objective of the current study was to study the outcome of trial of labour after caesarean section (TOLAC), the indications for emergency repeat cesarean section and to determine the maternal and fetal prognosis in vaginal birth after caesarian section (VBAC) at Tshikaji Mission Hospital. Patients, Material and Methods: This is a retrospective study of the records of 126 women were selected to undergo the TOLAC in the department of gynecology and obstetrics at the Tshikaji Mission Hospital over the period from January 1<sup>st</sup> to December 31<sup>st</sup>, 2021. The data on demography, antenatal care, labour and delivery and outcomes were collected from the maternity unit of this hospital. The data were analyzed using SPSS version 2.0. Results: The TOLAC in 126 studied women. The course of work allowed vaginal delivery 107 parturient women, a success rate of successful VBAC of 85% after the TOLAC. The repeat emergency cesarean section was necessary for delivery in 15% of cases for failed TOLAC. There was no maternal mortality, but we recorded one fetal death or 0.8% of perinatal mortality, 2 cases of cicatricial dehiscence, the incidence of 1.6%. Maternal morbidity after delivery on cicatricial uterus was dominated by postpartum hemorrhages, with 19 cases or 15.1% of cases. Cervical dilatation of more than 3 cm at the time of admission, the parity more than 3 and were the significant factors in favor of a successful VBAC. Birth weight of more than 3500 g, fetal distress and malpresentation were associated with a lower success rate of VBAC. The TOLAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas. Conclusion: Pregnancy on a cicatricial uterus represents a high-risk pregnancy. Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas. There is a significantly high vaginal birth after caesarian section (VBAC) success rate among selected women undergoing trial of scar in Tshikaji Hospital. TOLAC remains the option for childbirth in low resource settings as Kasai region in DRC. Adequate patient education and counselling in addition to appropriate patient selection for TOLAC remain the cornerstone to achieving high VBAC success rate.展开更多
