目的:通过对水中分娩新生儿脐动脉血气分析,评价水中分娩对胎儿的安全性。方法:对362例水中分娩新生儿生后立即采取脐动脉血进行血气分析,并与同期传统阴道分娩349例新生儿脐动脉血气进行比较。结果:水中分娩组平均脐动脉血pH值与对照组各为(7.29±0.11)及(7.22±0.17),差别有显著性意义(P<0.05),水中分娩组脐动脉血pH≤7.20者占9.4%,对照组脐动脉血pH≤7.20者占11.7%,差别无显著性意义(P>0.05)。结论:水中分娩不增加新生儿窒息及酸中毒的危险性,对胎儿是安全的。
OBJECTIVE: To evaluate the safety of childbirth in fetuses by analyzing the umbilical arterial blood gas of newborns in water. Methods: The umbilical artery blood was taken immediately after birth in 362 newborn infants who were born in water and compared with the umbilical arterial blood gases of 349 newborns in the traditional vaginal delivery. Results: The average umbilical arterial blood pH in water delivery group was (7.29 ± 0.11) and (7.22 ± 0.17) respectively, with significant difference (P <0.05). The umbilical arterial blood pH in water delivery group was less than or equal to 7.20 9.4%, control group umbilical artery blood pH≤7.20 accounted for 11.7%, the difference was not significant (P> 0.05). Conclusion: Childbirth does not increase the risk of neonatal asphyxia and acidosis and is safe for the fetus.
