A cricothyroidotomy is a life-saving procedure, performed as a final option to emergency airway algorithms, and is essential for all clinicians who perform emergency airway management. The bougie-assisted cricothyroidotomy (BAC) is a novel technique that may be performed faster and with fewer complications than other traditional approaches. There is no established standard set of steps to guide the instruction of BAC performance. This study sought to systematically develop a BAC checklist for novice instruction using a modified Delphi methodology and international airway experts.
A literature review informed the creation of a preliminary BAC checklist. A three round, modified Delphi method was used to establish a BAC checklist intended for novice-level instruction. The consensus level for each step and the final checklist were predefined at 80%. Participants were international airway experts identified by study personnel and snowball sampling.
Fourteen international airway experts across six acute care specialities participated in the study. The checklist was refined using a seven-point rating scale for each item and participant comments. A 17-item checklist was developed with expert consensus achieved after three rounds. Internal consistency, measured with Cronbach's α, was 0.855 (95% confidence interval 0.73-0.94).
This modified Delphi-derived checklist is the first systematically developed list of essential steps for guiding BAC instruction for novice learners. This tool serves to standardize BAC skill instruction and provide learners with a structured and consistent set of steps for deliberate practice.
环甲膜切开术是一种救生程序,作为紧急气道算法的最终选择,对于所有进行紧急气道管理的临床医生来说都是必不可少的。球囊引导的环甲膜切开术(BAC)是一种新的技术,可能比其他传统方法更快且并发症更少。目前还没有一套既定的标准步骤来指导 BAC 操作的教学。本研究旨在使用改良 Delphi 方法和国际气道专家系统地为初学者制定 BAC 检查表。
文献复习为初步 BAC 检查表的创建提供了信息。使用三轮改良 Delphi 法建立了针对初学者教学的 BAC 检查表。每个步骤和最终检查表的共识水平预先设定为 80%。参与者是由研究人员和雪球抽样确定的国际气道专家。
来自六个急症护理专业的 14 名国际气道专家参加了这项研究。使用七点量表对每个项目和参与者的意见进行了细化,对检查表进行了修订。经过三轮,制定了一个包含 17 个项目的检查表,达成了专家共识。内部一致性用 Cronbach's α 测量,为 0.855(95%置信区间 0.73-0.94)。
本研究通过改良 Delphi 法制定的检查表是指导初学者 BAC 教学的基本步骤的首个系统制定的清单。该工具用于标准化 BAC 技能教学,并为学习者提供一套结构化和一致的步骤,以便进行刻意练习。
