ObjectiveTo investigate the factors affecting the results of vaginal birth after cesarean (VBAC). MethodsWe retrospectively analyzed the data from 80 pregnant women of prior cesarean section with intention of vaginal delivery between October 2012 and July 2013. According to the final way of delivery, the 80 women were divided into two groups, the VBAC group (40 cases) and repeated cesarean section (RCS) group (40 cases). The clinical characteristics of the two groups were compared and further multi-variant analysis was conducted. Besides, 40 women with successful repeated vaginal delivery were included as controls. The delivery time and bleeding volume were compared between the VBAC group and the control group. ResultsThe three determinant factors associated with the present VBAC were: Arrested labor as the indication of prior cesarean section [OR=1.601, 95%CI (1.025, 2.469), P=0.04], Bishop Score [OR=3.757, 95%CI (1.437, 8.772), P=0.01] and infant weight [OR=1.391, 95%CI (1.124, 2.583), P=0.03]. The VBAC group presented a higher Episiotomy rate than the RCS group. No significant difference was found between the VBAC and the control group regarding the delivery time [(6.71±2.94) vs. (5.88±2.47) hours, P=0.176] and bleeding volume [(259.13± 75.31) vs. (230.36±67.44) mL, P=0.076]. ConclusionVBAC presents a better and faster recovery with a shorter hospital stay. But the indication of VBAC should be strictly followed to ensure the safety of both mothers and babies.
Objective To review the adverse event of hysterectomy caused by postoperative infection after cesarean section, formulate prevention and control strategies in combination with risk assessment tools, promote the standardization of perioperative management, reduce the medical burden on pregnant women, and improve patient satisfaction. Methods The two adverse events of hysterectomy caused by postoperative infection after cesarean section that occurred in the obstetrics ward between October and November 2024 were selected as the research objects. A root cause analysis and risk assessment team composed of personnel from multiple departments was established. Through interviews, observations, and data review, the potential failure modes and causes were sorted out. The risk priority number (RPN) was calculated to determine the high-risk factors. Improvement strategies were formulated and implemented. After two-month implementation, the RPN scores and the compliance of various measures before and after the implementation were compared. Results Before the improvement, the total RPN of the healthcare failure mode and effects analysis was 367.8. When rechecked in January 2025, the total RPN after the improvement dropped to 105.7, and no serious adverse events occurred again. The compliance and passing rates of various operations significantly increased: the intervention rate for maternal malnutrition rose from 17.5% to 48.6%, the passing rate of appropriate timing for prophylactic use of antimicrobial agents before surgery increased from 50.5% to 81.0%, the compliance rate of scrubbing the vagina with disinfectant before surgery increased from 15.0% to 60.0%, the implementation rate of standardized skin disinfection during surgery rose from 66.7% to 95.2%, the passing rate of aseptic techniques and hand hygiene operations during surgery increased from 75.0% to 95.2%, and the timely submission rate of specimens from infected patients increased from 29.4% to 47.6%, and all these differences were statistically significant (P<0.05). Conclusion The combination of healthcare failure mode and effect analysis and root cause analysis can effectively improve adverse events during the perioperative period, optimize the perioperative management of cesarean section, and reduce the risk of infection.

Methods Clinical data of 1 157 cases of prolonged pregnancy were retrospectively analyzed during June 2008 to June 2009.They were divided into three groups according to the time of pregnancy.Group A: 449 cases, pregnant age 40+1 - 40+3 week; Group B:358 cases, pregnant age 40+4 - 40+6 weeks; Group C:350 cases, pregnant age 41 - 41+6 weeks. The incidence of amniotic fluid turbidity, the rate of cesarean section and the neonatal prognosis were compared among three groups. Results With the extension of time of pregnancy, the incidence of amniotic fluid turbidity and the rate of cesarean section were statistically different among three groups (Plt;0.05), neonatal score was low, and the number of cases who needed specialist treatment increased. Conclusion Prolonged pregnancy is a high-risk pregnancy.The monitoring and detection means for prolonged pregnancy should be strengthened.Termination of pregnancy should be considered if necessary.

Methods A total of 1200 cases who need cesarean section were randomly divided into 3 groups (400 cases in each group): simple local anesthesia group (group L), droperidolfentanyl strengthen local anesthesia group (group F) and analgestic and amnestic anesthesia group (group J). Group L was only local anesthesia. Group F was local anesthesia supplemented by droperidol 500 mg, fentanyl 015 mg. Group J was supplemented with ketamine on the basis of group F. Then the time from anesthesia to the fetus delivery, Neonatal Apgar score of one and five minutes, the blood pressure fluctuations, amount of bleeding in or after surgery and the satisfaction of anesthesia were all observed. Results Compared with group L and F, the delivery time was no significant difference, Apgar score increased, blood pressure fluctuations in pregnant women was not obviously varied, amount of bleeding in or after surgery had no significantly increase, and the satisfaction of anesthesia improved markedly all in group J. Conclusions The analgestic and amnestic anesthesia assisted by lowdose ketamine, in cesarean section, is better than local anesthesia and strengthen local anesthesia by droperidolfentanyl, which is worthy to be popularized, especially in emergency caesarean section.
ObjectiveTo evaluate the effect of different rehydration strategies on the incidence of spinal anesthesia-induced hypotension and neonatal outcomes during elective cesarean section.MethodsWe searched PubMed, Embase, the Cochran Library, China National Knowledge Internet, VIP database, Wanfang database, and China Biology Medicine database from inception to January 2018, to collect randomized controlled trials (RCTs) about the incidence of spinal anesthesia-induced hypotension during elective cesarean section and neonatal outcomes of preloading or coloading. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the study. Meta-analysis was conducted using RevMan 5.3 software.ResultsA total of 11 RCTs were included, including 894 parturients, of whom 448 cases in the preload group and 446 cases in the coload group. Comparing with the preload group, the incidence of spinal anesthesia-induced hypotension during cesarean section in the coload group significantly decreased [risk ratio (RR)=1.27, 95% confidence interval (CI) (1.13, 1.43), P<0.000 1]. Subgroup analysis showed that in the crystalloid fluid group, the difference in the incidence of hypotension between the preload group and the coload group was statistically significant [RR=1.48, 95%CI (1.26, 1.73), P<0.000 01]; while in the colloidal fluid group, the difference in the the incidence of hypotension between the preload group and the coload group was not significant [RR=1.00, 95%CI (0.85, 1.17), P=0.96]. The lowest systolic blood pressure, the incidence of nausea and vomiting, and neonatal outcomes had no significant difference between the two groups.ConclusionsComparing with preloading crystalloid fluid, rapid infusion of crystalloid fluid at the same time implementation of spinal anesthesia could significantly reduce the incidence of hypotension during cesarean section while there was no superiority in infusion of colloid fluid. There was no significant effect on the severity of hypotension, nausea and vomiting, and neonatal outcomes. Due to the limitation of the quantity and quality of the included studies, the above conclusions need to be verified by more high-quality studies.
