Heart Rate Variability to Detect Complications After Scheduled Colorectal Surgery for Cancer or Inflammatory Disease

What this Trial Is About

Researchers are studying how variations in heart rate, known as heart rate variability, relate to complications after scheduled colorectal surgery. The study focuses on how the autonomic nervous system, which controls heart rate through sympathetic and parasympathetic activity, affects recovery. Specifically, the research explores how a failure to return to normal heart rate variability in the postoperative period may be linked to complications in colorectal surgery patients. This observational study uses heart rate variability measurements collected from patients undergoing scheduled colorectal surgery for conditions such as cancer, diverticulitis, or chronic inflammatory bowel disease. Heart rate and RR interval data are analyzed using specialized software called KUBIOS. The study does not involve any treatment but monitors patients heart rate variations from Day 1 to Day 7 after surgery. Participants will have their heart rate variability monitored daily from the first day after surgery up to seven days or until hospital discharge. Researchers will evaluate how heart rate variability correlates with various postoperative complications, including anastomotic fistula, abscesses, infections, hemorrhagic shock, and death rate. The study involves standard clinical assessments and data collection during the hospital stay, with outcome measurements focused on the first week after surgery.
