Hidden gut risk after CPR: new study investigates colon damage
NCT ID NCT07359313
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how often colon damage (ischemia) happens in people who survive cardiac arrest and receive CPR. Researchers will perform a bedside colonoscopy 24-36 hours after CPR to check for colon injury. The goal is to better understand this complication and improve care for future patients.
