Early-Phase Computed Tomography Bowel Diameter and Neurological Outcomes Post-Extracorporeal Cardiopulmonary Resuscitation
By Hiyama S, Inoue M, Inoue K and 3 others.
Abstract
Aim
We aimed to conduct an exploratory investigation on the association between bowel diameter on early-phase abdominal computed tomography (CT) and neurological outcomes in patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA).
Methods
This observational study included patients who underwent ECPR for OHCA and abdominal CT before intensive care unit admission between January 2015 and December 2021 at a tertiary emergency medical center. Maximum bowel diameter was measured with a picture archiving and communication system by an investigator blinded to outcomes. The primary endpoint was unfavorable neurological outcomes at 1 month, defined as Cerebral Performance Category 3-5. The discriminatory ability of bowel diameter was assessed using the area under the receiver operating characteristic curve (AUC).
