本文通过266例持续性枕后位产程处理分析表明,其发生率为1.42%,手术产率为87.59%,其中剖宫产率为31.58%。孕周>40周、胎儿体重≥3500g、潜伏期≥8h者剖宫产可能性明显增加,自然分娩机会减少。本组校正围产儿病死亡率为0,新生儿窒息率18%,新生儿窒息率随活跃期增长、第二产程延长而增加;新生儿体重≥3500g者窒息率明显高于体重<3500g者,而高体重儿剖宫产窒息率较阴道分娩者为低;合并胎儿宫内窘迫者较无窘迫者窒息率增高,但与分娩方式关系不大。
In this paper, 266 consecutive cases of sustained posterior occipital birth process analysis showed that the incidence was 1.42%, the surgical yield was 87.59%, of which cesarean section rate was 31.58%. Gestational age> 40 weeks, fetal weight ≥ 3500g, latent period ≥ 8h significantly increased the possibility of cesarean section, reduce the chance of natural childbirth. The correction of perinatal mortality in this group was 0, neonatal asphyxia 18%, neonatal asphyxia increased with the active period, prolonged the second stage of labor increased; neonatal weight 3500g asphyxia was significantly higher than those weighing <3500g, The cesarean section rate of asymptomatic children with high birth weight was lower than those with vaginal delivery. The asphyxia rate of those with fetal distress was higher than those without. However, it was not related to the mode of delivery.
