Objective:

To investigate the clinical value of emergency bedside echocardiography in the etiological diagnosis of sudden cardiac arrest (SCA) and during the implementation of cardiopulmonary resuscitation (CPR).

Methods:

A retrospective analysis of 16 SCA patients given CPR was performed. All patients underwent emergency bedside echocardiography. The clinical data and the statistics of cardiac structure

systolic function as well as intracardiac flow dynamic status acquired by echocardiography were recorded.

Results:

Of 16 patients

15 cases were detected with abnormalities of cardiac structure and functions by emergency bedside echocardiography

only one case showed no significant

abnormality. The cardiac diseases detected by echocardiography were the cause of cardiac arrest in 12 cases

not the cause of cardiac arrest in 1 case

not sure if the cause of cardiac arrest in 2 cases. Echocardiography was performed in 4 cases during CPR and 12 afterwards. Four cases were performed echocardiography equal to or more than twice. The success ratio for the first CPR was 75% (12/16). And the final survival ratio was 50% (8/16).

Conclusion:

Emergency bedside echocardiography has quite important clinical value in the process of treating cardiac arrest. It can help promptly identify the status of cardiac structures and functions

imply the primary cardiac diseases and the relationship with the onset of cardiac arrest

guide the implementation of CPR and evaluate the prognosis of patients.
