# Transesophageal echocardiogram contributes to high-quality cardiopulmonary resuscitation: a case report

## TL;DR

A transesophageal echocardiogram helped guide high-quality CPR during a cardiac arrest, leading to a full recovery in a patient.

## Contribution

This case report demonstrates the utility of TEE in guiding prolonged CPR during perioperative cardiac arrest.

## Key findings

- TEE assisted in high-quality CPR during a 90-minute resuscitation effort.
- The patient regained spontaneous circulation and had no long-term complications.
- TEE's use during CPR may improve outcomes in prolonged cardiac arrest cases.

## Abstract

Difficulties to identify the cause of cardiac arrest in a short period of time lead to prolonging the time for cardiopulmonary resuscitation (CPR) and to poor survival. Transesophageal echocardiogram (TEE) can assist CPR of long duration and improve outcome.

In this case report, a 50-year-old man was scheduled to undergo a endoscopic cervical discectomy under general anesthesia. The patient suffered a sudden cardiac arrest during the operation, and a high-quality CPR was performed with the the help of TEE. Although the exact etiology of cardiac arrest remained unclear and the CPR was performed for up to 90 min, the patient returned to spontaneous circulation, and was discharged after a month of treatment and rehabilitation, resuming his daily activities. After a one year of follow-up, he still was without any sequelae.

Perioperative cardiac arrest is unpredictable and catastrophic, so high-quality CPR is essential. TEE’s excellent features make it ideal for use on resuscitation and can improve the outcome of cardiac arrest.
