[摘要] 目的 初步探讨对阴道试产中诊断为胎儿窘迫而采取不同助产方式对新生儿脐动脉血血气的影响。 方法 选择2012年4～5月在本院经阴道试产分娩的足月新生儿217例，该217例新生儿在阴道分娩过程中均诊断为胎儿窘迫，而分别采取了会阴侧切术、胎头吸引术及产钳术助产。在胎儿娩出后1 min行脐动脉血血气分析。 结果 会阴侧切率为29.49%，胎头吸引器助产率为36.87%，产钳助产率为33.64%。经会阴侧切术娩出新生儿脐动脉血血气pH值≥7.10且< 7.20为32例(50.00%)，pH < 7.10为7例(10.93%)；经胎头吸引器助产新生儿脐动脉血血气pH值≥7.10且< 7.20为39例(48.75%)，pH < 7.10为6例(7.50%)；经产钳助产新生儿脐动脉血血气pH值≥7.10且< 7.20为16例(21.92%)，pH < 7.10为4例(5.48%)。 结论 合适的助产方式可以减少因分娩过程中出现胎儿窘迫而引起的新生儿脐动脉血血气pH值的降低。解决胎儿窘迫急需分娩者，产钳术比胎头吸引术安全可靠。

[Abstract] Objective To primary investigate the influence of the neonatal umbilical arterial blood gas between the different way of vaginal assistant in fetal distress. Methods Two hundred and seventeen full—term neonates that diagnosis of fetal distress with vaginal delivery and suffered lateral episiotomy， vacuum extraction or obstetric forceps delivery were collected from April to May 2012， and the neonatal umbilical arterial blood gas were detected within one minute after fetus delivery. Results Rate of lateral episiotomy， vacuum extraction and obstetric forceps delivery was 29.49%， 36.87%， and 33.64% respectively； the number of 7.10 ≤ pH < 7.20 in lateral episiotomy， vacuum extraction and obstetric forceps delivery were 32 cases (50%)， 39 cases (48.75%)， and 16 cases (21.92%) respectively； the number of pH < 7 ......
