At 8 cm cervical dilatation she experienced spontaneous rupture of membrane with clear liquor. Cord prolapse was detected and was prepared for caesarian section meanwhile she was kept in knee chest position and bladder was filled with normal saline 0.9%. 30 min before operation she was fully dilated with signs of Non reassuring fetal status, vacuum extraction was done to assist delivery as soon as possible. The APGAR score was 6 and 10 in the first and fifth minutes respectively. Mother and the baby were discharged the next day in good condition.展开更多
目的:探讨联合使用胎儿头围、腹围和产程进展角(angle of progression,AOP)预测阴道助产术(胎头吸引术和产钳助产术)难度的价值。方法:采用前瞻性观察性研究,选取2017年5月—2022年7月在广西壮族自治区人民医院产科行阴道助产术的足月...目的:探讨联合使用胎儿头围、腹围和产程进展角(angle of progression,AOP)预测阴道助产术(胎头吸引术和产钳助产术)难度的价值。方法:采用前瞻性观察性研究,选取2017年5月—2022年7月在广西壮族自治区人民医院产科行阴道助产术的足月单胎初产妇共64例。收集孕妇入院后的临床资料,超声测量胎儿头围和腹围,助产前采用经会阴超声测量AOP(宫缩间期和宫缩期AOP均值分别记为AOP1、AOP2)。按助产结局分组,有下列1种及以上情况纳入困难或失败组(A组):需要3次及以上牵引;中途更换助产器械后助产牵引成功(胎头吸引术失败转产钳助产术);阴道助产失败转剖宫产终止妊娠;术者主观评估助产失败可能性高,行剖宫产终止妊娠;新生儿产伤;会阴Ⅲ度或Ⅳ裂伤。其余纳入成功且容易组(B组)。将胎儿头围、腹围、AOP1和AOP2进行不同组合建立4个多因素Logistic回归模型,使用受试者操作特征(receiver operator characteristic,ROC)曲线评估4个模型对助产难度的区分度,选出ROC曲线下面积(area under the curve,AUC)最大者。Hosmer-Lemeshow检验评估最优模型的校准度,并利用Bootstrap重复取样(1000次)的方法进行内部验证。结果:2组间阴道指检胎头位置、末次牵引时长、末次牵引不同初始牵引方向占比、胎儿腹围、AOP1、AOP2、脐动脉血气pH值和新生儿窒息率比较差异有统计学意义(均P<0.05)。同时纳入胎儿头围、胎儿腹围、AOP1和AOP2建立的模型AUC最大(AUC=0.917,95%CI:0.821~0.972,Z=11.676,P<0.001),Hosmer-Lemeshow检验显示χ2=5.873,P=0.661,模型区分度和校准度均良好。内部验证结果表明模型有较好的一致性。结论:联合应用胎儿头围、腹围、AOP1和AOP2建立的简单模型能较好地预测阴道助产术难度,为临床决策提供一定依据。展开更多

There was lack of published data in Chinese population particularly on studying the risk of OASIS for nonrotational outlet forceps. This study was to determine the incidence and risk factors of OASIS. Methods： This is a retrospective cohort study carried out in a tertiary referral hospital in Hong Kong. The control group was selected randomly. Univariate and multivariate logistic regression analysis was performed to evaluate the influence of potential risk factors on OASIS. This study reviewed the obstetric records of OASIS women and random control from January 2011 to June 2014. Univariate and multivariate logistic regression analysis was performed to evaluate the influence of potential risk factors on OASIS. Results： Of 15,446 women delivered, 49 had OASIS. The percentage of OASIS increased from 0.3% （2011） to 0.38% （2014）. There was an increasing trend of OASIS in attempted spontaneous vaginal delivery without episiotorny （P 〈 0.01）~ but it did not increase the OASIS risk （P = 0.46）. Univariate analysis of 49 cases and 438 control subjects showed that forceps delivery （odds ratio [OR] -8.73, P 〈 0.01 ）, prolong second stage of labor （OR = 1.43, P 〈 0.01） increased the risk lbr OASIS. In multivariate regression models, only lbrceps delivery （OR = 6.28, P 〈 0.01） proved to be independent risk factor. Conclusions： The incidence of OASIS in Chinese women was increased alter 2012, but still lower than the reported figures in the literature. Outlet forceps delivery could be a possible associated risk factor.展开更多
