Using Sodium Bicarbonate During Prolonged Cardiopulmonary Resuscitation in Prehospital Setting; a Retrospective Cross-sectional Study.

Introduction: Although the 2020 American Heart Association (AHA) guidelines recommend that sodium bicarbonate (SB) be avoided during routine cardiopulmonary resuscitation (CPR) a limited number of studies have examined the effects of SB injection during prolonged CPR (>15 min) in prehospital setting. The present study aimed to examine the effects of prehospital SB use during prolonged CPR on patients' outcome.

Methods: In this retrospective cross-sectional study adult patients aged >18 years who experienced a non-traumatic, out-of-hospital cardiac arrest (OHCA) were compared regarding three outcomes, namely return of spontaneous circulation (ROSC), ROSC > 20 minute, and survival to discharge, based on receiving or not-receiving SB during CPR.

Sustained Return of Spontaneous Circulation Following Out-of-Hospital Cardiac Arrest; Developing a Predictive Model Based on Multivariate Analysis.

Introduction: Identifying the predictive factors of sustained return of spontaneous circulation (ROSC) following out-of-hospital cardiac arrest (OHCA) will be helpful in management of these patients. This study aimed to develop a predictive model in this regard.

Methods: In a retrospective observational study, data of adult patients with OHCA, were collected from Vajira emergency medical services patient care report.

Predictive Factors of Outcome in Cases of Out-of-hospital Cardiac Arrest Due to Traffic Accident Injuries in Thailand; a National Database Study.

Introduction: Traffic accident injury is one of the global leading causes of death and an important public health problem. This study aimed to evaluate the predictive factors of return of spontaneous circulation (ROSC) at the scene in out-of-hospital cardiac arrest (OHCA) due to traffic accidents.

Methods: This retrospective cross-sectional study was conducted on cases of OHCA due to traffic accident, who were resuscitated at the scene by emergency medical services (EMS) in Bankok, Thiland, from January 1, 2020, to December 31, 2020 (1 year).
