The reliability of "leak" as a criterion for elective extubation of children with croup treated with nasotracheal intubation was studied during the three month "croup epidemic" in Ontario of September 1, 1983 to November 30, 1983. Twenty-eight patients experienced 36 extubations; 31 planned and five accidental. Three of 23 (13 per cent) planned extubations with "leak" required reintubation whereas three of eight (38 per cent) children electively extubated after seven days of intubation without "leak" required reintubation. "Leak" is a helpful but not absolute prognostic indicator of a successful extubation.
1983年9月1日至1983年11月30日安大略省为期三个月的“哮吼流行期”期间，对以“漏气”作为经鼻气管插管治疗的哮吼患儿择期拔管标准的可靠性进行了研究。28例患者经历了36次拔管；31次为计划拔管，5次为意外拔管。23例（13%）有“漏气”情况的计划拔管中有3例需要重新插管，而8例插管7天后无“漏气”情况而择期拔管的患儿中有3例（38%）需要重新插管。“漏气”是拔管成功的一个有用但非绝对的预后指标。
