Abstract
Objective: Cardiopulmonary arrest is a devastating outcome of some clinical situations
and requires strict implementation of cardiopulmonary resuscitation (CPR) protocols.
Since ultrasound is one of the recommended tools to determine the presence of cardiac
movements and may be a predictor of the outcome, this study examined the relationship
between echocardiographic findings during CPR with patients’ outcomes.
Methods: This cross-sectional prospective observational study was conducted on patients
with cardio-respiratory arrest in the emergency department of Shariaty hospital during
2019. sampling method was random. Echocardiography was done at the patient’s bedside
during the CPR process in accordance with the last advanced cardiac life support (ACLS)
guidelines, on two points, after the end of the second and 10th minutes from the start of
CPR. The echocardiography findings (cardiac movement vs standstill) were recorded, and
patient outcomes were followed. Thirty-two patients enrolled in this study with a mean
age of 56.9±15.3 years. Chi-square and Mann-Whitney U tests were used to calculate the
association between heart contractions during resuscitation and the outcomes via SPSS
V.22. Fisher’s exact test and Kruskal-Wallis test were used to evaluate the relationship
between heart rhythm in the second and tenth minutes with the outcomes of CPR.
Results: The presence of cardiac movement in the 10th minute of CPR, in contrast to the
findings of the second minute, had a significant correlation with the success rate of CPR
and outcomes (P<0.05). Moreover, patients with ventricular tachycardia (VT)/ventricular
fibrillation (VF) cardiac rhythm had a better resuscitation rate, 24-hour survival rate, and
better outcome than patients with other cardiac rhythms and asystole (P<0.05).
Conclusion: Echocardiographic findings in the 10th minute of the CPR process can be
used as a prognostic factor for cardiac arrest
