Cricothyroidotomy is an excellent emergency procedure for airway obstruction which cannot be relieved by oral or nasal intubation. Important factors for a device for emergency cricothyroidotomy include selective airways, an airway lumen of sufficient size to permit suctioning or adequate airflow during spontaneous breathing, and the ability to assess depth and angle of penetration. An instrument that is simple to insert, offers protection against overpenetration, minimizes bleeding, and provides an airway offering a variety of lumens is described. It appears to provide an ideal means of accomplishing an emergency cricothyroidotomy for airway obstruction.
环甲膜切开术是一种用于无法通过口插管或鼻插管缓解的气道梗阻的出色急救手术。用于紧急环甲膜切开术的器械的重要因素包括选择性气道、足够大的气道腔以允许在自主呼吸期间进行吸引或有足够的气流，以及评估穿刺深度和角度的能力。本文描述了一种易于插入、可防止过度穿刺、使出血最小化并提供具有多种腔道的气道的器械。它似乎为完成气道梗阻的紧急环甲膜切开术提供了一种理想的方法。
