Intubation is an essential, life-saving skill but associated with a high risk for adverse outcomes. Intubation protocols have been implemented to increase success and reduce complications, but the impact of protocol conformance is not known. Our study aimed to determine association between conformance with an intubation process model and outcomes.
An interdisciplinary expert panel developed a process model of tasks and sequencing deemed necessary for successful intubation. The model was then retrospectively used to review videos of intubations from 1 February, 2014, to 31 January, 2016, in a paediatric emergency department at a time when no process model or protocol was in existence.
We evaluated 113 patients, 77 (68%) were successfully intubated on first attempt. Model conformance was associated with a higher likelihood of first attempt success when using direct laryngoscopy (OR 1.09, 95% CI 1.01 to 1.18). The use of video laryngoscopy was associated with an overall higher likelihood of success on first attempt (OR 2.54, 95% CI 1.10 to 5.88). Thirty-seven patients (33%) experienced adverse events. Model conformance was the only factor associated with a lower odds of adverse events (OR 0.94, 95% CI 0.88 to 0.99).
Conformance with a task-based expert-derived process model for emergency intubation was associated with a higher rate of success on first intubation attempt when using direct laryngoscopy and a lower odds of associated adverse events. Further evaluation of the impact of human factors, such as teamwork and decision-making, on intubation process conformance and success and outcomes is needed.
插管是一项至关重要的救命技能,但也存在很高的不良后果风险。为了提高成功率并减少并发症,已经实施了插管规程,但规程的遵守情况的影响尚不清楚。我们的研究旨在确定遵守插管过程模型与结果之间的关联。
一个跨学科的专家小组制定了一个被认为是成功插管所必需的任务和顺序的过程模型。然后,该模型被用于回顾 2014 年 2 月 1 日至 2016 年 1 月 31 日期间在一家儿科急诊室进行的插管视频,此时没有过程模型或规程。
我们评估了 113 例患者,其中 77 例(68%)在首次尝试时成功插管。当使用直接喉镜时,模型的一致性与首次尝试成功率更高相关(OR 1.09,95%CI 1.01 至 1.18)。使用视频喉镜与首次尝试总体成功率更高相关(OR 2.54,95%CI 1.10 至 5.88)。37 例(33%)患者发生不良事件。只有模型的一致性与不良事件的可能性降低相关(OR 0.94,95%CI 0.88 至 0.99)。
在使用直接喉镜进行紧急插管时,遵守基于任务的专家衍生过程模型与首次插管尝试的成功率更高相关,与相关不良事件的可能性降低相关。需要进一步评估人为因素(如团队合作和决策制定)对插管过程一致性和成功率以及结果的影响。
