Abstract

Purpose: Temperature targets in patients with cardiac arrest and return of spontaneous circulation (ROSC) have changed. Changes to higher temperature targets have been associated with higher breakthrough fevers and mortality. A post-ROSC normothermia bundle was developed to improve compliance with temperature targets.

Methods: In August 2021, "ad hoc" normothermia at the discretion of the attending intensivist was initiated. In December 2021, a post-ROSC normothermia protocol was implemented, incorporating a rigorous, stepwise approach to fever prevention (temperature ≥ 37.8). We conducted a before-after cohort study of all adult patients post-ROSC who survived to intensive care unit admission between August 1, 2021, and April 1, 2022. They were divided into "ad hoc" and "protocol" groups. Clinical outcomes compared included fevers, active cooling, and paralytic use.

Results: Fifty-eight post-ROSC patients were admitted; 24 in the "ad hoc" and 34 in the "protocol" groups. Patient demographics were similar between groups. The "ad hoc" group had more shockable rhythms (67% vs 24%, P = .001) and cardiac catheterizations (42% vs 15%, P = .03). The "protocol" group were significantly less likely to have a fever at 40 h (6% vs 40%, P < .001) and 72 h (14% vs 65%, P ≤ .001). Patients in the normothermia "protocol" used significantly less neuromuscular blocking agents (24% vs 50%, P = .05). The normothermia "protocol" resulted in similar mortality (56% vs 58%, P = 1.0).

Conclusion: Use of a normothermia "protocol" resulted in fewer fevers and less neuromuscular blocker administration compared to "ad hoc" management. A protocolized approach for improved quality of care should be considered in institutions adopting normothermia.
