Factors Related to Resuscitation Success and Prognosis of Cardiopulmonary Arrest Cases

Abstract

Background: In cases where return of spontaneous circulation (ROSC) is provided in the Emergency Department (ED) after cardiopulmonary arrest (CA), it is important to investigate the parameters affecting ROSC rates, to determine the factors affecting the survival status and prognosis in the short and medium term, and to determine to what extent these factors affect the prognosis. Materials and methods: This is a cross-sectional study that retrospectively investigates the factors affecting the success of resuscitation over a 5-year period in out-of-hospital cardiopulmonary arrest (OHCA) cases. Results: We determined that ROSC was achieved in 26.1% of 1616 adult cardiopulmonary arrest cases, 14.8% survived the first 24 hours, and 3.8% were discharged from the hospital. Conclusion: We determined that ROSC decreased by 21% with a 1-mg increase in the amount of adrenaline used, by 98% with a 1 mmol/L increase in HCO3 (std) value, by 27% with a 1 mmol/L increase in BE (B) value, and by 15% with a 1 mmol/L increase in lactate value. In terms of short-term survival, we found that a 1 mmol/L increase in lactate value reduced the probability of survival by 12%, and a 1 mEq/L increase in K value decreased the probability by 29%. With regard to the probability of survival in the medium term, we determined that the growth in age by 1 year decreased the probability by 4%, and the increase in K value by 1 mEq/L decreased the probability by 35%.
