Nitrous oxide analgesia is a safe alternative to parenteral narcotics for outpatient surgical procedures. This type of analgesia is effective, well tolerated by most age groups, easily administered, rapidly reversible and associated with a low incidence of serious side effects. Hypoxia can be prevented by using fail-safe equipment, by observing prescribed limitations on nitrous oxide concentrations and by administering 100 percent oxygen on termination of nitrous oxide administration.
氧化亚氮镇痛法是门诊外科手术中肠外麻醉药的一种安全替代方法。这种镇痛法效果显著，大多数年龄组都能很好耐受，易于给药，作用迅速可逆，且严重副作用发生率低。通过使用故障安全设备、遵守规定的氧化亚氮浓度限制以及在停止使用氧化亚氮后给予100%的氧气，可以预防缺氧。
