The aim of this study was to use cardiac sonography as a diagnostic method for the treatment of patients with cardiac arrest and asystole and PEA rhythm by emergency physicians and, if possible, taking therapeutic measures based on specific etiology.
Design
Randomized, parallel group clinical trial
Settings and conduct
In the present study, all adult patients who entered the emergency department of Alzahra and Kashani hospitals with cardiac arrest are divided into two groups using a randomized blocking method. In the first group, the patient undergoes ultrasound during the resuscitation and in the second group, the standard resuscitation is performed.
Participants/Inclusion and exclusion criteria
Inclusion criteria: All patients with cardiopulmonary arrest without organized rhythm. Exclusion criteria: Failure to perform ultrasound resuscitation.
Intervention groups
During resuscitation, without interference in resuscitation measures, an ultrasound probe placed in the subxiphoid area by an emergency medicine specialist or a senior assistant. The resuscitation team leader will be informed the ultrasound performer 5 seconds before the check pulse so that he takes a four-chamber view of the heart within 10 seconds of checking the pulse. In the first time, cardiac organized contraction and pericardial effusion are checked and recorded. In the second check pulse, the presence of hypovolemia (right ventricle collapse) and pulmonary embolism (right ventricular enlargement with left ventricular collapse) is checked and recorded, and in the third check pulse, a pneumothorax is checked in the event of a strong clinical suspicion of it.
Main outcome variables
The main outcome of the study is to determine and cure the reversible causes of cardiac arrest and its impact on the final outcome of the patients.

Intervention groups

Description
Intervention group: Sonography during resuscitation in the check pulse period. During resuscitation, an ultrasound curved array probe (2–4 MHz) placed in the subxiphoid area. The resuscitation team leader will be informed the ultrasound performer 5 seconds before the check pulse so that he takes a four-chamber view of the heart within 10 seconds of checking the pulse. In the first time, cardiac organized contraction and pericardial effusion are checked and recorded. In the second check pulse, the presence of hypovolemia (right ventricle collapse) and pulmonary embolism (right ventricular enlargement with left ventricular collapse) is checked and recorded, and in the third check pulse, a pneumothorax is checked in the event of a strong clinical suspicion of it.
