NCT06619977

Brief Summary

Thу goal of this study was to learn whether intraoperative analgesia nociception monitoring (ANI) could be beneficial during intraoperative monitoring for patients undergoing living donor liver resections. The main questions it aims to answer are:

  • Could it impact the average dose of intraoperative fentanyl used?
  • Could it impact the occurrence of postoperative nausea and vomiting? Patients who were included in this study underwent living liver donor resections with fentanyl infusion and thoracic epidural analgesia. Two groups of patients were analysed - the ANI group (n = 24), in which fentanyl dose was adjusted with ANI monitoring, and the retrospective control group (n = 25) with a standard practice without ANI monitoring.

Outcome Measures

Primary Outcomes (1)

  • Postoperative Nausea and Vomiting

    from enrollment to the first 48 hours postoperatively

Study Arms (2)

Standard practice retrospective group

NO INTERVENTION

Patients undergoing living liver donor resections with general anesthesia without ANI monitoring.

ANI guided group

EXPERIMENTAL

Patients undergoing living liver donor resections with general anesthesia with ANI nociception monitoring.

Device: Analgesia nociception monitoring (ANI)

Interventions

Analgesia nociception index (ANI; MetroDoloris Medical Systems, Lille, France) is a noninvasive tool for monitoring the intraoperative state of the autonomic nervous system, in particular - the parasympathetic nervous system. The ANI algorithm uses data from one lead ECG trace. Heart rate variability, or the beat-to-beat alterations in heart rate, is a well-known and recognised noninvasive indicator of autonomic nervous system activity.
