脐带异常影响胎儿、胎盘血液循环。轻者引起胎儿宫内发育迟缓,重者引起胎儿宫内窘迫,猝死、新生儿窒息。本文总结1990年5月至1991年7月间分娩的627例新生儿,其中204例脐带异常,现分析如下: 资料分析一、资料 627例新生儿中脐带异常204例,发生率32.5％,其中缠绕151例,扭转47例、脱垂3例,打结2例,过短9例,过长41例(两种情况并存分别统计),正常组423例,脐带长度平均为50.6±20cm,异常组脐带长度平均为57±42.9cm,脐带过长并发脐带绕颈的32/41例,发生率为78％,较邹玲报告的(72％)高,脐带缠绕151例,其中绕颈一周者119例,占78.8％;绕颈二周者26例占17.2％,绕
Umbilical cord abnormalities affect the fetus, placental blood circulation. Light caused by intrauterine growth retardation, severe fetal distress caused by sudden death, neonatal asphyxia. This article summarizes the birth of 627 cases between May 1990 to July 1991 627 cases of newborns, of which 204 cases of umbilical cord abnormalities, are analyzed as follows: Data Analysis First, the data of 627 newborn cases of umbilical cord in 204 cases, the incidence rate of 32.5%, of which 151 cases were entangled, 47 cases were reversed, 3 cases were prolapsed, 2 cases were knotted, 9 cases were too short and 41 cases were too long (statistical coexistence in two cases). In normal group, 423 cases had an average cord length of 50.6 ± 20cm. The average length of the umbilical cord was 57 ± 42.9 cm. The incidence of umbilical cord circumference was 32/41 (78%), which was higher than that reported by Zouling (72%). Umbilical cord wound around 151 cases, of which around the neck 119 cases, accounting for 78.8%; 26 cases around the neck two weeks accounted for 17.2%, around
