Emergency airway management represents an event with high acuity but unpredictable frequency and therefore presents a challenge for adequate staffing. Given circadian and seasonal variations, we hypothesized that the majority of emergency airway events happen after normal working hours and during the winter months.
A retrospective analysis of 1,482 intubations by an emergency airway team over a 3-y period was performed. The data were obtained from hospitalized patients who required emergency airway management in a large academic medical center. A database of emergency airway consultations was analyzed for intubation time and date information, as well as geographic location within the hospital.
A greater percentage of emergency intubations occurred during day shift hours (7 am to 7 pm) compared with night shift hours, 57% and 43%, respectively (P < .01). The monthly frequency of intubations was not uniformly distributed across the year (P < .01). The greatest percentage of intubations was performed in February (10.9%), with the lowest being recorded in August (4.7%).
Emergency airway service utilization is highest during daytime hours, with seasonal variations composed of higher consults in the winter and lower consults in the summer.
紧急气道管理是一种高急症但频率不可预测的事件，因此对充足的人员配备构成挑战。考虑到昼夜节律和季节变化，我们假设大多数紧急气道事件发生在正常工作时间之后和冬季。
对一个紧急气道团队在3年期间进行的1482次插管进行回顾性分析。数据来自一家大型学术医疗中心需要紧急气道管理的住院患者。分析了一个紧急气道会诊数据库，以获取插管时间和日期信息以及医院内的地理位置。
与夜班时间相比，白班时间（上午7点至晚上7点）进行的紧急插管比例更高，分别为57%和43%（P < .01）。插管的月度频率在全年分布不均（P < .01）。插管比例最高的是2月（10.9%），最低的是8月（4.7%）。
紧急气道服务的使用率在白天最高，存在季节性变化，冬季会诊较多，夏季会诊较少。
