Outcomes of Out-of-Hospital Cardiac Arrest during the Coronavirus disease 2019 pandemic

Abstract

Introduction: Research into the variables influencing successful out-of-hospital cardiac arrest (OHCA) resuscitation is crucial for developing a pre-hospital emergency care system.

Objective: To evaluate the survival rate and factors of emergency medical services that affect the outcome of OHCA patients.

Method: Using retrospective descriptive research as the method. From January 1st, 2020, to December 31st, 2021, all medical records of OHCA patients transported by the emergency medical team to Maharat Nakhon Ratchasima Hospital were analyzed.

Result: A study of 221 patients revealed that the return of spontaneous circulation rate was 50.68%, the survival rate to admission was 33.94%, and the survival rate to discharge was 2.26%. The majority of the survivors (65.61%) were male. Age on average: 61.60±15.59 years. A considerably higher survival rate was observed in patients with diabetes, malignancy, cardiac arrest due to hypoxia, and a total CPR time of fewer than 30 minutes. In addition, intravenous fluid administered before hospital arrival significantly impacted patient survival (adjusted RR 2.15, 95% CI 1.04–4.60).

Conclusion: The ROSC rate was high, but the survival rate to discharge was poor. Furthermore,

pre-hospital intravenous fluid infusion improves the survival rates for OHCA patients.
