Abstract:
Objective To investigate the causes of failure of manually rotating fetal head technology and its delivery outcomes.Methods One hundred and Ninety-eight cases with persistent occipito transverse position or persistent occipitoposterior position admitted to our hospital form January 2008 to December 2010 were enrolled as our subjects.According to the result of manually rotating fetal head technology,these patients were divided into the success group (126 cases) and the failure group (72 cases).The information related to delivery was recorded.Results The proportion of fetal weight ≥ 3500 g in the failure group was 76.4％ (55/72),higher than that of the success group(31.7％ (40/126)),and there has statistic significant difference (x2 =30.177,P =0.001).The proportion of uterine inertia in the failure group(58.3％ (42/72)) was higher than that of the success group(38.1％ (48/126)),and there has statistic significant difference (x2 =7.569,P =0.006).The proportion of critical or low-grade narrow birth canal in the failure group(38.9％ (28/72)) was significantly higher than that of the success group (23.8％ (30/126)),and there has statistic significant difference (x2 =5.030,P =0.002).The proportion of the improper time for manually rotating fetal head (opening of cervix was less than 6 cm,and fetal head was above ischial spine and opening of cervix was 8-10 cm,fetal head reach to more than 2 cm lower of ischial spine) in the failure group was 61.1％ (44/72),which was significantly higher than that of the success group (38.9 ％ (49/126)),and there has statistic significant difference (x2 =9.084,P =0.003).The proportion of maternal and neonatal complications (postpartum hemorrhage,puerperal morbidity,fetal distress,neonatal asphyxia) in the failure group were significantly higher than those of the success group (x2 =9.586,P =0.002 ; x2 =9.334,P =0.002 ; x2 =5.910,P =0.015 ; x2 =5.240,P =0.022).The proportion of cesarean section in the failure group(72.2％ (52/72)) was significantly higher than that of the success group(34.1％ (43/126)),and there has statistic significant difference(x2 =26.641,P =0.001).Conclusion The manually rotating fetal head technology can transform from dystocia to normal delivery and decrease the rate of cesarean section.It is necessary to prevent and deal with the failure causes of manually rotating fetal head technology.And it must be cautious to perform the follow-up correction and trial production after the failure of previous correction.
