Abstract

The frequency, severity, and duration of oxygen desaturation during oral surgical procedures in outpatients was measured. Sixty patients divided into six groups received either lidocaine; lidocaine, diazepam, and meperidine; lidocaine, diazepam, meperidine, and headphone music; lidocaine, diazepam, meperidine, and nitrous oxide; lidocaine, diazepam, meperidine, methohexital, and nitrous oxide; or lidocaine and nitrous oxide. Forty-three percent of the 30 patients who did not receive supplemental oxygen experienced clinically significant oxygen desaturation (greater than 5%) with a mean duration of 4.6 minutes. Only 13% of the patients who received supplemental oxygen had significant desaturation ranging from ten seconds to 12.3 minutes with a mean duration of 1.4 minutes. An unexpected finding was hypoxia in patients receiving only lidocaine anesthesia.

摘要

对门诊患者口腔外科手术期间氧饱和度降低的频率、严重程度和持续时间进行了测量。60名患者被分为六组，分别接受利多卡因；利多卡因、地西泮和哌替啶；利多卡因、地西泮、哌替啶和头戴式耳机播放的音乐；利多卡因、地西泮、哌替啶和一氧化二氮；利多卡因、地西泮、哌替啶、甲己炔巴比妥和一氧化二氮；或利多卡因和一氧化二氮。在未接受补充氧气的30名患者中，43%出现了临床上显著的氧饱和度降低（大于5%），平均持续时间为4.6分钟。接受补充氧气的患者中，只有13%出现了从10秒到12.3分钟不等的显著饱和度降低，平均持续时间为1.4分钟。一个意外发现是仅接受利多卡因麻醉的患者出现了缺氧。
