Read our Colorectal Neoplasms research guide →After major abdominal surgery, many patients have trouble breathing deeply because of pain from their incision. This study uses ultrasound to measure how well your diaphragm (the main muscle that controls breathing) contracts before surgery and one hour after surgery. The researchers want to understand which pain relief methods—such as IV medications, epidural catheters, or nerve blocks—help your breathing muscle work best during recovery.
Difficulty breathing after abdominal surgery is a common problem that can slow down recovery. By comparing how different pain relief methods affect your breathing muscle, doctors hope to find the best ways to help patients breathe easier and recover faster after surgery.
You will have ultrasound scans of your diaphragm (breathing muscle) taken before your surgery and again about one hour after surgery. The ultrasound is painless and non-invasive—the technician will place a probe on your skin to take measurements as you breathe in and out. Your participation is focused on these measurements and doesn't require you to do anything beyond standard surgical care and the pain relief method assigned by the study team.
