Monitoring heart rate variability in patients undergoing major surgery
Monitoring Functional Capacity Through Heart Rate Variability Within the Multimodal Rehabilitation Program in Adult Surgery
This study is testing if monitoring heart rate changes can help doctors understand how ready patients are for major surgery and improve their recovery.

What this trial studies
This observational cohort study investigates the use of heart rate variability (HRV) monitoring through the Analgesia Nociception Index (ANI) in adult patients scheduled for major surgery as part of a multimodal rehabilitation program. The study aims to correlate HRV indices with functional capacity, physiological reserve, and frailty during the prehabilitation phase. HRV will be assessed at two key points: during the initial pre-anesthesia consultation and one week prior to surgery, with results compared to various functional and frailty assessments.
Who should consider this trial
Good fit: Ideal candidates include adults over 18 years scheduled for major surgery who can provide informed consent.
Not a fit: Patients requiring urgent surgery, those with severe cognitive impairment, or those with cardiac arrhythmias may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance preoperative care by optimizing patient rehabilitation and reducing postoperative complications.
How similar studies have performed: While the use of HRV monitoring in surgical settings is emerging, this specific approach within a multimodal rehabilitation context is relatively novel.
