Overview
The main objective of this study is to study the impact of intravenous dexmedetomidine combined with locoregional anesthesia on postoperative pain in children undergoing surgery.
Secondary objectives was to compare beetwen groups : Post-operative pain; opioid consumption; incidence of emergence delirium, post-operative behavioral disorders, length of stay in the PACU, adverse events , parental satisfaction and quality of life.The goal of this clinical trial is to assess intravenous dexmedetomidine to prevent post-operative pain in children undergoing surgery.
This study is prospective and children will be randomized in one of the following arm:
- Dexmedetomidine (experimental treatment)
- Placebo The experimental treatment or placebo will be administrated at one time point at the time of incision.
Participants and their legal representative will have to respond to questionnaires at several time points following the surgery: Day 1, Week 1, Month 3 and Month 6.
Description
Postoperative pain, which can develop into chronic pain in children, can have a significant impact on the quality of life of the child and their parents. Management of acute postoperative pain is crucial to prevent chronic pain, and perioperative opioid sparing aims to reduce opioid side effects. The emergence of postoperative delirium (ED) is also a concern, as it can cause intense agitation and diagnostic difficulties. Dexmedetomidine, in addition to its sedative and analgesic effects, has been shown to prolong the duration and effectiveness of regional anesthesia (LAR), thereby reducing the need for opioids and attenuating the severity of postoperative delirium. Its use in these settings could improve pain management and reduce complications associated with pediatric surgery, thus offering a promising therapeutic option.
