初产头浮与难产

RELATIONSHIP BETWEEN PRIMIPARA WITH FLOATING HEAD AND DYSTOCIA

为分析妊娠末期和产前难产因素，提高围产期质量，本文对182例初产头浮孕产妇进行综合分析。初产头浮组脐带异常119例，占65．4％（P＜0．01）；其中78例剖宫分娩，占66．4％（P＜0．05）。初产头浮组与对照组中胎儿宫内窘迫的发生分别为61：28（P＜0．01）。初产头浮组中巨大儿87例（47．8％），对照组42例（23．1％）P＜0．01。初产头浮组骨盆异常的发生高于对照组（46：34）。初产头浮组总产程明显长于对照组（19．6±1．78：1．5±1．90）P＜0．01。发现初产头浮主要与脐带缠绕、巨大胎儿、骨盆异常和胎盘低置有关，且增加难产和剖宫产机率。

In ordor to make sure the dystocia factors in the term and pre-labor patients for the improvement of the quality of perintal period, we analysed synthetically 182 cases of primipara with floating head (PFH)through statistics. Out of 119 (65. 4 % )cases with abnormal cord in the PHF, 78 accepted Cesarean Section(CS)accounting for 66. 4% (P<0. 01). 61 cases suffering from fetal distress in PFH showed a sharp contrast with 28 in the control group(P<0.01 ); 87 (47. 8% )cases with macrosomia in PHF again formed contrast with 42 (23.1%) in the control (P<0.01),and the rate of abnormal pelvis in PFH was also higher than that in the control (46: 34). In addation,the general stage of labor in PFH was markedly prolonged compared with that in the con-trol (19. 6± 1. 78: 11. 5±1. 90, P<0.05 ). It is concluded that PFH is obviously related with umbilical cord around body,macrosomia,abnormal pelvis and placenta low implantation,and this may lead to a higher rate of dystocia and CS consequently.
