Factors affecting survival and neurological outcomes for patients who underwent cardiopulmonary resuscitation

Abstract

Objective: To determine the impact of arrest location, arrest reason, the return of spontaneous circulation positivity, duration of cardiopulmonary resuscitation, chest compression method, and cardiac rhythm at the time of hospital admission on survival rates and neurological outcome in cardiac arrest cases.

Methods: The retrospective study was conducted at Bolu Abant Izzet Baysal Training and Research Hospital, Turkey, and comprised data related to the period from January 1, 2016, to June 31, 2018, of patients who received cardiopulmonary resuscitation at the Emergency Department. Demographic characteristics of the patients, the return of spontaneous circulation, and 6-month survival rates were evaluated with the use of a modified Rankin scale. Data was analysed using SPSS 25.

Findings: Of the 177 cases, 109(61.58%) were male. The return of spontaneous circulation was noted in 72(40.68%) patients. In-hospital, cardiac arrest developed in 80(45.20%) patients, and chest compression wasperformed on 105(59.32%) with the use of a mechanical chest compression device. A non-shockable rhythm state was observed in 150(84.75%) patients, and 18(10.17%) survived at the end of the sixth month.

Conclusions: The return of spontaneous circulation rate was higher and the neurological prognosis was more positive in patients on whom cardiopulmonary resuscitation was performed for a shorter time period and who had a shockable cardiac rhythm at the time of admission.
