The Cardiopulmonary Resuscitation Success Rate and Its Related Factors in Patients Referred to Dr. Heshmat Hospital in Rasht, Iran

Abstract

Background: Cardiopulmonary Resuscitation (CPR) is an emergency procedure for the return of spontaneous circulation in patients with cardiac arrest. Many factors can affect the success of CPR. Objective: This study aims to investigate the success rate of CPR and its related factors in patients referred to Dr. Heshmat Hospital in Rasht, Iran. Methods: In this retrospective cohort study, participants were 1008 patients who had underwent CPR in Dr. Heshmat Hospital in Rasht, Iran. Data were collected from April 2016 to March 2019 using the Utstein style standard form, which assesses related factors and the times related to CPR. The association between CPR outcome and demographic/clinical factors was examined using independent samples t-test, chi-square test, and multiple logistic regression analysis. Results: The CPR success rate was 34.8%. The CPR success rate was higher in patients with no asystole rhythm, short CPR duration, and in-hospital cardiac arrest. Compared to patients in CCU ward, those received CPR in other wards (except ICU) were more likely to have successful CPR. Furthermore, in patients with in-hospital cardiac arrest, the odds of successful CPR decreased with the increase of age. Conclusion: Since patients with asystole rhythm had the lowest success rate of CPR and this rhythm occurs due to delay in initiation of treatment at the end of cardiac arrest, early treatment of patients with cardiac arrest caused by ventricular tachycardia or ventricular fibrillation can increase the chances of a successful CPR.

Investigating the outcomes of cardiopulmonary resuscitation and factors affecting it: A cross‐sectional study at Dr. Moaven Hospital, Sahneh City from 2014 to 2021

“…25 According to the findings of a study conducted by Moghadam Nia et al, there is not a statistically significant relationship between age and the success rate of CPR. 26 There was not a significant relationship between the history of resuscitation and the results of CPR in 8% of the patients who were resuscitated more than once, which was in contrast to the study of Alizadeh et al in which it was discovered that as the number of resuscitations for each patient increases, the final success rate reduces significantly, and this can be ascribed to complications produced by resuscitation. 15 68.2% of cases of cardiorespiratory arrest occurred inside the hospital and 31.8% outside the hospital, and according to the χ 2 test, there was no significant statistical difference between the place of the cardiorespiratory arrest (inside and outside the hospital) and the outcome of resuscitation.…”

“…Lima et al discovered that younger patients have a higher chance of survival and spontaneous recovery of blood circulation after a shorter period of resuscitation 25 . According to the findings of a study conducted by Moghadam Nia et al, there is not a statistically significant relationship between age and the success rate of CPR 26 . There was not a significant relationship between the history of resuscitation and the results of CPR in 8% of the patients who were resuscitated more than once, which was in contrast to the study of Alizadeh et al in which it was discovered that as the number of resuscitations for each patient increases, the final success rate reduces significantly, and this can be ascribed to complications produced by resuscitation 15 .…”
