Dexamethasone as a bupivacaine adjuvant for ultrasound-guided interscalene brachial plexus block: a prospective randomized study
Tóm tắt
Finding adjuvants to local anesthetic used in interscalene block that could efficiently extend the analgesia duration has recently been the focus of researchers. The aim of the work was to determine whether the addition of perineural dexamethasone to bupivacaine in-ultrasound guided interscalene block would prolong the duration of sensory analgesia in patients undergoing shoulder surgery.
This prospective, randomized, double-blinded study comprised 50 patients. They were randomly subdivided into 2 groups: group C [control] and group D [dexamethasone]. We noted a significant difference regarding the timing for the first rescue analgesia being shorter in group C than in group D with a
We concluded that the addition of 8 mg of perineural dexamethasone to 30 ml of 0.5% bupivacaine showed improvement in the postoperative analgesia in shoulder surgery without obvious complications.
