Intravenous Fluid Administration and the Survival of Pre hospital Resuscitated out of Hospital Cardiac Arrest Patients in Thailand

Introduction: Out of Hospital Cardiac Arrest (OHCA) is a leading cause of death worldwide. The Emergency Medical Service (EMS) provides early care to critical OHCA patients. Pre hospital intervention has been improving OHCA survival rate, however it is still unclear for the recommendation of routine infusion of Intravenous (IV) fluids during cardiac arrest resuscitation. Aim: This study aimed to determine whether IV fluid administration was associated with increasing survival of resuscitated OHCA patients and to assess the survival rate of resuscitated OHCA patients. Materials and Methods: This cross-sectional analytical study was conducted among 33,006 resuscitated OHCA patients who received emergency medical service in Thailand. Data set from the EMS Registry of the OHCA patients who received Advanced Life Support (ALS) and Cardiopulmonary Resuscitation (CPR) during January 2011 to December 2015 was enrolled as per inclusion criteria. Data were analysed by using both descriptive statistic and multiple logistic regression. Results: The result indicated that 27,270 OHCA patients (82.62%:95%CI=82.121-83.030%) survived until they reached hospital. In addition, after adjusting for effect modifiers and covariates, it was found that adult (≥18 years) with IV fluid administration were more likely to survive (adjusted OR=4.389; 95% CI: 3.911-4.744) when compared to children (
