The use of transesophageal echocardiogram (TEE) during cardiac arrest in the emergency department (ED) is a newer concept. TEE provides dynamic evaluation of chest compressions and rhythm analysis. Hand placement using external landmarks can result in maximal compression over the aorta, rather than the ventricles of the heart. We present the initial case of TEE performed in the out of hospital setting in an ambulance to facilitate cardiac arrest resuscitation using a disposable TEE probe. This case is a proof of concept that TEE can be successfully performed and contribute to clinical care of cardiac arrest in the out of hospital setting. Further research needs to be performed to determine the clinical benefit, indications, and curriculum for emergency providers to successfully deliver this potentially valuable resource prior to widespread adoption.
经食管超声心动图（TEE）在急诊科（ED）心脏骤停期间的使用是一个较新的概念。TEE 提供了对胸部按压和节律分析的动态评估。使用外部标志进行手部放置可导致主动脉上的最大压缩，而不是心脏的心室。我们介绍了在救护车外院环境中使用一次性 TEE 探头进行 TEE 的初始病例，以促进心脏骤停复苏。该病例证明 TEE 可以成功进行，并有助于外院心脏骤停的临床治疗。需要进一步研究以确定临床益处、适应症以及急诊提供者在广泛采用之前成功提供这一潜在有价值资源的课程。
