The aim of this meta-analysis was to quantify the effectiveness of aromatherapy for laboring women. We searched five electronic databases till November 15th 2013 including those Chinese and English language articles. A total of 4 eligible studies were identified. Aromatherapy was effective in reducing the length of labor, but there were no statistically significant effects in the use of pharmacological analgesia, spontaneous vaginal delivery, caesarean delivery and assisted vaginal birth. Due to the limited number of articles identified, the evidence is not sufficiently convincing that aromatherapy is an effective therapy for laboring women.展开更多
目的探究不同剂量缩宫素(oxytocin,OT)对剖宫产术后再次妊娠经阴道试产(trial of labor after cesareansection,TOLAC)孕妇产程进展、凝血功能和母婴结局的影响。方法回顾性分析138例TOLAC孕妇临床病历资料,根据产程中OT总用量分为低剂...目的探究不同剂量缩宫素(oxytocin,OT)对剖宫产术后再次妊娠经阴道试产(trial of labor after cesareansection,TOLAC)孕妇产程进展、凝血功能和母婴结局的影响。方法回顾性分析138例TOLAC孕妇临床病历资料,根据产程中OT总用量分为低剂量组61例、中剂量组45例和高剂量组32例,比较三组的产程进展、凝血功能、分娩方式、妊娠结局及围产儿结局。结果三组第一产程、第二产程、第三产程及总产程比较,差异均无统计学意义(P>0.05);与用药前比,三组用药后凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)均降低,纤维蛋白原(FIB)水平均升高,差异有统计学意义(P<0.05),三组间用药后PT、APTT、FIB比较差异无统计学意义(P>0.05)。低剂量组及中剂量组孕产妇的胎盘早剥、新生儿高胆红素血症发生率均低于高剂量组,差异有统计学意义(P<0.05)。结论OT可增强TOLAC孕妇子宫收缩力,改善凝血功能,但大剂量OT可能增加胎盘早剥及新生儿高胆红素血症发生风险。展开更多

Objective: Our study aimed to investigate the demographic and associated factors influencing vaginal birth after one cesarean (VBAC-1) success focusing on variables like pre-pregnancy BMI, diabetes, hypertension, education, and smoking. Study Design and Methods: In this retrospective study, we analyzed 285 cases (81 unsuccessful VBAC-1, 204 successful VBAC-1) from San Juan City Hospital (Puerto Rico) between January 1, 2019, and December 31, 2020. We used odds ratios and model selection comparison to assess the impact of variables on successful VBAC-1, using a significance threshold of 95% CI. Model selection assessed binomial model combinations using a generalized linear approach to identify key risk factors. Results: Unsuccessful VBAC-1 (a repeat cesarean), was associated with diabetes (OR: 0.376, p = 0.086), hypertension (OR: 0.23, p = 0.006), and university-educated women (OR: 1.372, p = 0.711). High school-educated women had an OR of 3.966 (p = 0.105), while overweight women were 0.481 times more likely to have unsuccessful VBAC-1 (p = 0.041). Significant associations were not found with obesity (OR: 0.574, p = 0.122), underweight/normal (OR: 1.01, p = 0.810), or smoking (OR: 1.227, p = 0.990). Conclusion: Results revealed women with higher education levels, hypertension, or diabetes are less likely to have a successful VBAC-1. Understanding the complex interactions affecting these outcomes is aimed at establishing guidelines for healthcare professionals to conduct systematic risk/benefit assessments. This study lays a foundation for evidence-based practices and policies, offering initial insights into VBAC-1 success factors in Puerto Rico.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
