Therapeutic hypothermia as a treatment option after out-ofhospital cardiac arrest: our experience.

Abstract

Aim To examine the effects of therapeutic hypothermia on the outcome of patients with the diagnosis of out-of-hospital cardiac arrest (OHCA). Methods The study included 76 patients who were hospitalised at the Medical Intensive Care Unit (MICU) of the Clinical Centre University of Sarajevo, with the diagnosis of out-of-hospital cardiac arrest, following the return of spontaneous circulation. Therapeutic hypothermia was performed with an average temperature of 33oC (32.3 - 34.1o C) on the patients who had coma, according to the Glasgow Coma Scale (GCS). Results Multiple organ dysfunction syndrome (MODS) significantly affected survival (p=0.0001), as its presence reduced patients' survival by 96%. In addition, ventricular fibrillation (VF) as the presenting rhythm, also significantly affected survival (p=0.019). A degree of patient's coma, as measured by the GCS, significantly affected survival (p=0.011). For each increasing point on the GCS, the chance for survival increased twice. Moreover, other physiological factors such as the pH and the lactate serum levels significantly affected patients' survival (p=0.012 and p=0.01, respectively). Conclusion In patients with the diagnosis of OHCA who underwent to the treatment with therapeutic hypothermia, verified VF as a presenting rhythm was a positive predictive factor for their outcome. Therefore, therapeutic hypothermia represents an option of therapeutic modality for this type of patients.
