The fetal heart rate was monitored during 30 deliveries by Caesarean section. General anaesthesia, but not epidural analgesia, caused a loss of beat-to-beat variation, but appeared to have no other adverse effects on fetal heart rate. The loss of beat-to-beat variation occurred after intravenous thiopentone and was most marked when atropine was used as premedication.
在30例剖宫产分娩过程中对胎儿心率进行了监测。全身麻醉而非硬膜外镇痛导致逐搏变化消失，但似乎对胎儿心率没有其他不良影响。逐搏变化的消失发生在静脉注射硫喷妥钠之后，且在使用阿托品作为术前用药时最为明显。
