Impact of coma duration on functional outcomes at discharge and long-term survival after cardiac arrest.

ABSTRACT:

Introduction

Awakening from coma is crucial for survivors of cardiac arrest, though coma duration is variable. We tested the association of coma duration with short-term functional recovery and long-term survival after cardiac arrest.

Methods

In this retrospective cohort study, we identified post-arrest patients who were comatose on presentation but awakened during hospitalization. We recorded demographics, arrest characteristics, days from arrest to awakening, and modified Rankin Scale (mRS) at hospital discharge. We compared discharge mRS between patients with short and long coma duration dichotomized at its median, 3, and 6 days. We compared long-term survival between patients with short and long coma duration who survived to hospital discharge. Finally, we used Cox regre
