Relationship between cardiac ultrasound findings during cardiopulmonary resuscitation with the outcome of patients

Cardiopulmonary arrest is a devastating outcome of some clinical situationsand requires strict implementation of cardiopulmonary resuscitation (CPR) protocols.Since ultrasound is one of the recommended tools to determine the presence of cardiacmovements and may be a predictor of the outcome, this study examined the relationshipbetween echocardiographic findings during CPR with patients’ outcomes. This cross-sectional prospective observational study was conducted on patientswith cardio-respiratory arrest in the emergency department of Shariaty hospital during2019. sampling method was random. Echocardiography was done at the patient’s bedsideduring 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 ofCPR. The echocardiography findings (cardiac movement vs standstill) were recorded, andpatient outcomes were followed. Thirty-two patients enrolled in this study with a meanage of 56.9±15.3 years. Chi-square and Mann-Whitney U tests were used to calculate theassociation between heart contractions during resuscitation and the outcomes via SPSSV.22. Fisher’s exact test and Kruskal-Wallis test were used to evaluate the relationshipbetween heart rhythm in the second and tenth minutes with the outcomes of CPR. The presence of cardiac movement in the 10th minute of CPR, in contrast to thefindings of the second minute, had a significant correlation with the success rate of CPRand outcomes (P<0.05). Moreover, patients with ventricular tachycardia (VT)/ventricularfibrillation (VF) cardiac rhythm had a better resuscitation rate, 24-hour survival rate, andbetter outcome than patients with other cardiac rhythms and asystole (P<0.05). Echocardiographic findings in the 10th minute of the CPR process can beused as a prognostic factor for cardiac arrest
