Impact of Cardiopulmonary Resuscitation Duration on the Neurological Outcomes of Out-of-Hospital Cardiac Arrest

Abstract

Background: Patients experiencing cardiac arrest outside medical facilities are at greater risk of death and might have negative neurological outcomes. Cardiopulmonary resuscitation duration affects neurological outcomes of such patients, which suggests that duration of CPR may be vital to patient outcomes.Objectives: The study aims to evaluate the impact of cardiopulmonary resuscitation duration on neurological outcome of patients who have suffered out-of-hospital cardiac arrest.Methods: Data were collected from emergency cases handled by a secondary hospital in industrial Jubail, Saudi Arabia, between 2015 and 2020. There were 257 out-of-hospital cardiac arrest cases, 236 of which resulted in death.Results: Bivariate analysis showed no significant association between cerebral performance category (CPC) outcomes and duration of CPR, gender and cause of death whereas there is statistically significant between CPC and age. (p = 0.001). However, a good CPC outcome was reported with a (mean) limited duration of 8.1 min of CPR; whereas, poor CPC outcomes were associated with prolonged periods of CPR, 13.2 min (mean). Similarly, youthfulness was associated with good CPC outcomes as revealed by the mean age of 5.8 years, whereas a mean rank of 14.9 years was aligned with a poor CPC outcome.Conclusion: Cardiopulmonary Resuscitation Duration out-of-hospital cardiac arrest does not significantly influence the patient neurological outcome in the current study hospital. Other variables may have a more significant effect.
