评价胎儿健康状况,过去曾用切胎儿皮肤间断测毛细管血pH值或连续监测组织pH法均有创伤性。本文拟在无并发症分娩时无创伤地连续测定经皮肤二氧化碳张力(tcPCO_2)的正常范围及酸中毒新生儿的tcPCO_2变化。本文共监测孕36～42周的122名产妇:76名初产妇,46名经产妇。和龄年龄27岁。第一产程平均503分(90～1,040),第二产程平均29分(2～120分)。剖宫产11例,胎头吸引29例,余为顺产。当宫口扩张>4cm且破膜者用吸附电极固定在胎头上,监测器与胎心产力监护仪连接并同时记录。产后立刻取脐动、静脉血做血气分析。分别用41℃和44℃电极于子宫颈每扩张1cm监测一次tcPCO_2
Evaluation of fetal health status, in the past had cut fetal skin intermittent measured capillary blood pH or continuous monitoring of tissue pH method are traumatic. This article intends to continuously determine the normal range of transcutaneous carbon dioxide tension (tcPCO_2) and the change of tcPCO_2 in neonates with acidosis without complications at delivery. This paper monitors a total of 122 maternal 36 to 42 weeks pregnant: 76 primipara, 46 maternal. And age 27 years old. The first stage of labor average 503 points (90 ~ 1,040), the second stage of labor average 29 points (2 ~ 120 points). Cesarean section in 11 cases, fetal head to attract 29 cases, more than for the delivery. When the cervix expansion> 4cm and the rupture of the membrane with electrodes fixed in the fetal head, monitor and fetal heart rate monitor connected and recorded at the same time. Obstetric immediately take the umbilical artery and venous blood to do blood gas analysis. The tcPCO_2 was monitored at 1 cm per cervix with 41 ° C and 44 ° C electrodes respectively
