Abstract

The purpose of this study was to assess whether the low frequency/critically high skill set of cricothyrotomy can be taught to emergency medicine residents at various levels of training. Our study was prospective in design, involving a brief survey concerning years of training, prior experience with cricothyrotomy, sense of comfort with procedure and number witnessed. Participants were emergency medicine residents PGY 2-5. After the survey, participants watched a demonstration video. Cricothyrotomy was then performed by participants on a mannequin using a preassembled cricothyrotomy kit, up to a maximum of 10 attempts. Successful performance was defined as 40 seconds or less as per the training model of Wong et al. When participants were pooled by attempt, the overall reduction in time performance reached a plateau by the 5th attempt. This plateau is identical to the plateau described by Wong in his study of cricothyrotomy training in anesthesiologists. When success was operationally defined as less than or equal to 40 seconds per attempt, the success threshold was definitely reached by the 2nd attempt and reached a plateau by the 5th attempt. Statistical significance of less than p= 0.01 was reached by the second attempt and reached a plateau (p=0.001) by the 5th attempt.
环甲环甲切开术关键技能假人训练
本研究的目的是评估环甲环切开术的低频率/临界高技能是否可以在不同级别的培训中教授给急诊住院医师。我们的研究在设计上是前瞻性的,包括一个简短的调查,关于训练的年数,以前的环甲环切开术的经验,对手术的舒适度和目睹的数量。参与者为急诊住院医师PGY 2-5。调查结束后,参与者观看了一段演示视频。然后由参与者使用预组装的环甲环切开术试剂盒在人体模型上进行环甲环切开术,最多可进行10次尝试。根据Wong等人的训练模型,成功的表现被定义为40秒或更短。当参与者按尝试分组时,时间表现的总体下降在第五次尝试时达到平稳状态。这个平台与Wong在麻醉师环甲环切开术训练研究中描述的平台相同。当成功在操作上定义为每次尝试少于或等于40秒时,成功阈值肯定在第二次尝试时达到,并在第五次尝试时达到平稳。第二次尝试达到统计学意义小于p= 0.01,第5次尝试达到平台期(p=0.001)。
