Variation in the Effect of Dexamethasone Associated With Axillary Plexus on the Occurrence of Rebound Pain

VEDR
Start date: March 15, 2023
Phase:
Study type: Observational

The study will evaluate pain and recovery after a single injection axillary plexus block combined with an intravenous dose of 0.1 mg/kg dexamethasone in ambulatory patients undergoing upper extremity bone surgery. The investigators will try to identify the risk factors involved in a decrease in the efficacy of dexamethaxone for the prevention of RP. The hypotheses are that : - The interindividual variability may modulate the preventive effect on "rebound pain" after axillary block, of pre-incisional administration of an anti-inflammatory dose of dexamethasone (0.1 mg/kg max 10 mg). - Patients with increased preoperative anxiety or underlying catastrophizing will experience more postoperative pain as the axillary PNB dissipates. - Elevated preoperative salivary lipocortin 1 and cortisol levels result in a lesser preventive effect of dexamethasone on the development of rebound pain.
