OUTCOMES OF CARDIOPULMONARY RESUSCITATION (CPR) IN EMERGENCY DEPARTMENT OF AFIC & NIHD. OUT-OF-HOSPITAL VERSUS WITNESSEDCARDIAC ARREST: A COMPARATIVE STUDY

Abstract

Objective: To compare the clinical characteristics and outcome of cardiopulmonary resuscitation (CPR)in patients
with out-of-hospital cardiac arrest and witnessed-cardiac arrest in Emergency Department of AFIC & NIHD.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Emergency Department of Armed Forces Institute of Cardiology & National
Institute of Heart Diseases Rawalpindi, from 1stNovember 2016 till 31stJanuary 2017.
Material and Methods: All the patients, presented with out-of-hospital cardiac arrest and witnessed-cardiac
arrest, in emergency department during our study time period were included. Center of disease studies (CDC)
registry for CPR was modified and modified/adapted as a data collection tool.
Results: A total number of 163 patients were recruited in our study, upon which CPR were performed in the
emergency department. The mean age of the patients was 61.7±10.3 years. Mean duration of CPR was 32.1±2.3
minutes. Total number of CPR performed for witnessed cardiac arrest (in hospital) were 61(37.4%) while CPR
performed upon the patients with out-of-hospital cardiac arrest were 102(62.5%).Reasons for CPR were found to
be VT, VF, asystole, heart block, cardiac and respiratory arrest (p=0.03). The most common underlying disease
was acute left ventricular failure (LVF), in 22(21.5%) patients, followed by dilated cardiomyopathy (DCM)
19(18.6%) and acute myocardial infarction in 17(16.6%) patients (p=0.01). About 59(96.7%) patients revived out of
63 patients, who were given CPR after witnessed-cardiac arrest while 71(69.6%) patients revived out of 102

Conclusion: Our study results yielded that witnessed-cardiac arrest patients have more survival as compared to
out-of-hospital cardiac arrest patients.
