If a pregnant woman has premature rupture of membranes during labor and finds amniotic fluid contamination, if the degree of contamination is not particularly serious, it is once contaminated, and the fetal heart rate is good or the labor is progressing smoothly, closely monitor the labor and fetal heart rate changes, if the labor is progressing smoothly, the labor can be ended by normal delivery; if the amniotic fluid fecal contamination is serious or the fetal heart rate is not good, it is recommended to end the labor by cesarean section in time. Amniotic fluid fecal contamination can easily cause neonatal asphyxia, therefore, in case of amniotic fluid fecal contamination, we should closely observe the change of fetal heart rate, end the labor in time, and give penicillin or vitamin K1 intramuscular injection after the delivery of the newborn to prevent the occurrence of aspiration syndrome and prevent neonatal infection.
