Filter by: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.
80 American Society of Anesthesiologists (ASA) grade I-II patients, 18-60 years old,scheduled for elective upper limb orthopaedic surgery under supraclavicular brachial plexus block, were included in this prospective study. The patients were randomly assigned to group R (Ropivacaine alone) and group RD (Ropivacaine and dexmedetomidine) (40 patients in each group). Group R received Ropivacaine 0.50% (30 cc) + placebo and group RD received Ropivacaine 0.50% (30 cc) + dexmedetomidine 1 µg/kg.
Adding dexamethasone to local anesthetic will significantly prolong duration of brachial plexus anesthesia and analgesia.
