Frailty in Adult Surgery Clinical Trial
Official title:
Monitoring Functional Capacity Through Heart Rate Variability Within the Multimodal Rehabilitation Program in Adult Surgery
This prospective, observational cohort study investigates heart rate variability (HRV) monitoring using the Analgesia Nociception Index (ANI) monitor in adult patients undergoing major surgery within a multimodal rehabilitation program. The objective is to correlate HRV indices with functional capacity, physiological reserve, and frailty during the prehabilitation phase.
The study evaluates HRV using the ANI monitor to determine adaptation to training load, optimize analgesic and anesthetic dosing, and predict postoperative complications. The HRV indices of Energy (SDNN) and ANI (HFnu) are monitored at two points: the initial pre-anesthesia consultation and one week before surgery. Results will be compared with the 6-minute walk test, MUST nutrition screening scale, and clinical frailty and FRAIL scales. ;
