由于剖宫产时麻醉往往可影响子宫胎盘循环。本文将７０例剖宫产孕妇分为两组，于麻醉后分娩前分别给予吸氧或不吸氧，通过传感器放置不同位置，对胎儿娩出后１－１０分钟和１５分钟进行连续ＳＰＯ２监测，得出分娩前吸氧产妇的新生儿较不吸氧产妇的新生儿１－４分钟内的ＳＰＯ２显著为高。说明分娩前吸氧对预防或纠正胎儿缺氧是极为有益的，并可作为新生儿复苏的一项指标以验证复苏的效果。 Anesthesia during cesarean delivery can often affect uteroplacental circulation. This article will be 70 cases of cesarean section pregnant women were divided into two groups before giving birth anesthesia were given oxygen or not, respectively, through the sensor placed in different locations, 1-10 minutes after delivery of the fetus and 15 minutes for continuous SPO2 monitoring Newborn infants who gave birth before delivery had a significantly higher SPO2 within 1-4 minutes than newborns who did not receive oxygen. Description of oxygen before delivery is very beneficial to prevent or correct fetal hypoxia, and can be used as an indicator of neonatal resuscitation to verify the effect of resuscitation.
