胎膜破裂前后羊水及脐血厌氧菌培养68例分析

对６８例胎膜早破、临产后破膜及胎膜未破的孕产妇，在剖宫产术中取羊水及脐血作厌氧菌培养。结果：普通培养（＋）１５例次，厌氧培养（＋）２０例次，阳性结果在胎膜早破组和临产破膜组比较无明显差异（Ｐ〉０．０５）；两破膜组与胎膜未破组比较有显著差异（Ｐ〈０．００１）；感染组与非感染组比较，前者破膜距手术时间较后者明显延长（Ｐ〈０．００１）。胎膜未破组也有阳性结果出现。认为：①产科感染中厌氧菌感染占半数以上；

Anaerobic culture of amniotic fluid and umbilical cord blood before and after the rupture of fetal membranes:Analysis of 68 cases.

Objective:To determine the correlation between the obstetrical infection and the rupture of fetal membranes.Design:Anaerobic culture was performed in amniotic fluid and umbilical cord blood in 68 labour women (including 18 cases of premature rupture of fetal membranes,19 parturient rupture and 31 unrupture).Results:The results showed that 15 cases were positive in ordinary culture and 20 in anaerobic culture.There was not significant difference between the positive result of parturient rupture group and premature rupture group(P<0.005).Positive results of the two ruptured groups were much higher than that of the unruptured group(P<0.01).The duration from the rupture of fetal membrane to operation in infective group was much longer than that in the uninfective group(P<0.001).Conclusion:(1)Pregnancy should be terminated as soon as possible after the rupture of fetal membrane to reduce the infection;(2)Anaerobic infection accounts for 50% or more in obstetrical infection;(3)Antibiotics and metronidazoli should be used in cesarean section to avoid infection \ \
