Neurological Outcomes of Normothermia versus Targeted Temperature Management in Post-cardiac Arrest Syndrome.

Abstract

To determine the neurological outcome of targeted temperature management (TTM)for patients scoring lower than 8 on the Glasgow coma scale (GCS) upon return of spontaneous circulation (ROSC) after cardiac arrest. Retrospective cohort study. Department of Anaesthesiology and Reanimation, Sakarya University Education And Research Hospital, Sakarya, Turkey from January 2018 to October 2019. Data of patients hospitalised in the AnaesthesiaIntensive Care unit for cardiac arrest receiving TTM and standard supportive therapy were analysed. Neurological outcome was evaluated with cerebral performance category (CPC) scores. Hospital stay and 30-day mortality was also noted. Data from 58 patients were analysed; 31 had received standard supportive therapy (non-TTM group) and 27 were treated with TTM (TTM group). There was no significant difference in hospital stay and patients' 30-day mortality between the two groups. The number of patients in the TTM group with CPC scores of 1 and 2, rated as a good neurological result, was significantly higher (n=11,40.7%) than in the non-TTM group (n=2, 6.5%;p=0.002). The number of patients with CPC scores of 3 and 4, rated as having a neurological disability,was higher in the non-TTM group (n = 9, 29%) than in the TTM group (n=1, 3.7%). Neurological results were better in the TTM group of patients with ROSC. However, there was no significant difference in mortality between the TTMand non-TTM groups.
