Transcutaneous scalp oxygen tension (tcPO2) was measured during labour in 40 fetuses, using a modified Clark electrode (Radiometer, Copenhagen). In 24 of the fetuses the recordings were of good quality during the second stage of labour. After delivery the acid-base status and oxygenation of the umbilical cord blood was measured. A correlation was found between the tcPO2 and umbilical artery oxygen saturation (r = 0.56, p less than 0.01) and umbilical artery PO2 (r = 0.56, p less than 0.01). Furuthermore, a positive correlation was found between the area beneath the recorded tcPO2 curve during the last 10 minutes and the umbilical artery pH (r = 0.50, p less than 0.05). The data suggest that continuous transcutaneous PO2 measurement may be of value in monitoring high risk patients during labour.
使用改良的克拉克电极(Radiometer,哥本哈根)对40例胎儿在分娩过程中进行经皮头皮氧分压(tcPO2)测量。其中24例胎儿在第二产程中的记录质量良好。分娩后测量脐血的酸碱状态和氧合情况。发现tcPO2与脐动脉氧饱和度(r = 0.56,p < 0.01)以及脐动脉PO2(r = 0.56,p < 0.01)之间存在相关性。此外,在最后10分钟记录的tcPO2曲线下面积与脐动脉pH之间存在正相关(r = 0.50,p <
