Abstract

Background
In-hospital cardiac arrest is a common situation in hospital settings. Therefore, health-care providers should understand the reasons that could affect the results of cardiopulmonary resuscitation. We aimed to determine the independent predictors for poor outcomes after the return of spontaneous circulation in In-hospital cardiac arrest patients, and also look for a relationship between patient’s background parameters and the status at intensive care unit.

Methods
We did a retrospective cohort study using cardiac arrest patients admitted to the intensive care unit after successful cardiopulmonary resuscitation between 2011–2015. Patients’ data were gathered from hospital database. Estimated probabilities of survival were computed using the Kaplan-Meier method. Cox proportional hazard models were used to determine associated risk factors for mortality.

Results
In total 197 cardiac arrest patients were admitted to anesthesia intensive care unit after successful cardiopulmonary resuscitation in a 4-years period. Of 197 patients, 170 (86.3%) died in intensive care unit. Median of survival days was 4 days. Comorbidity (p =  0.01), higher duration of cardiopulmonary resuscitation (p =  0.02), lower Glasgow Coma Score (p =  0.00), abnormal lactate level (p =  0.00), and abnormal mean blood pressure (p =  0.01) were the main predictors for increased mortality in cardiac arrest patients after intensive care unit admission.

Conclusion
The consequent clinical status of the patients is affected by the physiological state after return of spontaneous circulation. Comorbidity, higher duration of cardiopulmonary resuscitation, lower arrival Glasgow Coma Score, abnormal lactate level, and abnormal mean blood pressure were the main predictors for increased mortality in patients admitted to the intensive care unit after successful cardiopulmonary resuscitation.
