Forty-six American Society of Anesthesiologists Class I and II adults were randomly assigned to one to two study groups. Each subject received 0.7 microgram/kg of fentanyl and a titrated dose of midazolam. One group received 100% supplemental oxygen (O2) while another group received 50% nitrous oxide (N2O) and 50% O2. End-tidal carbon dioxide (EtCO2) and O2 saturation (SpO2) were measured at 5-min intervals throughout the procedure. We conclude that there was no significant difference in EtCO2 or O2 saturation between the two groups.
46名美国麻醉医师协会I级和II级成年患者被随机分配到一至两个研究组。每位受试者接受0.7微克/千克的芬太尼和滴定剂量的咪达唑仑。一组接受100%的补充氧气(O2),而另一组接受50%的氧化亚氮(N2O)和50%的O2。在整个过程中每隔5分钟测量呼气末二氧化碳(EtCO2)和氧饱和度(SpO2)。我们得出结论,两组之间的EtCO2或氧饱和度没有显著差异。
