Upper airway obstructions are usually acute emergencies. Coniotomy is the last option to secure the airway and can be supported by sonography. The aim of this study was to establish a training program to teach these skills.
The training consisted of theoretical training with an additional video presentation (10 minutes each) and practical training (45 minutes). Evaluations were completed before (T1) and after (T2) the training to measure prior experience and satisfaction with the training as well as subjective and objective competence levels. At T2, a practical test was also completed by n=113 participants. A standardized evaluation form was used to document the results of the practical test.
A large proportion of the participants had neither seen a coniotomy (64.6%) nor performed one independently (79.6%). Significant improvement (T1 to T2) was measured with regard to the subjective assessment of competence (p<0.001). The training received positive ratings for all items tested (scale ranges 1-2). During practical tests, the participants achieved an average of 89.2% of the possible points and needed a mean of 101 ±23 seconds to identify the conic ligament.
Structured training for sonographic identification of the conic ligament leads to significant improvement in the subjective assessment of competence and a high objective competence level in a short period of time. This type of training should be standardized in head and neck ultrasound training in the future.
上呼吸道梗阻通常是急性紧急情况。环甲膜切开术是确保气道通畅的最后手段，超声检查可为其提供支持。本研究的目的是建立一个培训项目来教授这些技能。
培训包括理论培训及额外的视频演示（各10分钟）和实践培训（45分钟）。在培训前（T1）和培训后（T2）进行评估，以衡量先前经验、对培训的满意度以及主观和客观能力水平。在T2时，n = 113名参与者还完成了一项实践测试。使用标准化评估表记录实践测试结果。
很大一部分参与者既未见过环甲膜切开术（64.6%），也未独立进行过该操作（79.6%）。在能力的主观评估方面（T1至T2）有显著改善（p < 0.001）。培训在所有测试项目上均获得了积极评价（评分范围为1 - 2）。在实践测试中，参与者平均获得了可能分数的89.2%，识别圆锥韧带平均需要101±23秒。
针对超声识别圆锥韧带的结构化培训可在短时间内显著改善能力的主观评估并达到较高的客观能力水平。这种类型的培训未来应在头颈超声培训中标准化。
