Intraoperative Fentanyl Consumption Guided by Analgesia Nociception Index

Status Completed

Clinical Trial Summary

Balanced anesthesia needs optimization of hypnotic, relaxant, and narcotic. Administration of hypnotic drugs can be monitored by bispectral index score (BIS), while the dosage of muscle relaxants can be guided by train-of four (TOF). However, administration of narcotics lacks objective monitor. Overdosage of narcotic may lead to delayed awakening, while underdosage may lead to high degree of postoperative pain. Recently, there is a monitor, Analgesic Nociceptive Index (ANI) monitor, designed to guide the administration of narcotics. There are many descriptive studies supporting the correlation of ANI score and pain score but there are still very few randomized control studies which report the efficacy of ANI in clinical practice.

Clinical Trial Description

Objective: To evaluate the efficacy of ANI to guide the administration of intraoperative fentanyl.

Methods: Sixty female patients undergoing breast surgery with balanced anesthesia will be randomized into 2 groups. The first group will receive fentanyl according to standard practice of attending anesthesiologists. The second group will receive fentanyl according to ANI score protocol.

Primary outcome: Postoperative pain numeric rating scale (NRS) score during 60 minutes in postanesthetic care unit (PACU).

Secondary outcomes: Total intraoperative dose of fentanyl and postoperative nausea/vomiting and sedation score in PACU. ;
