Randomized Controlled Trial
Electromyographic assessment of dexamethasone in treatment of post-tonsillectomy pain: randomized, placebo-controlled trial.
Surface electromyographic (sEMG) study of post-tonsillectomy swallow-evoked muscular reactions was performed to assess analgesic properties of dexamethasone. ⋯ If dexamethasone is administered, the reduction of the postoperative pain could be secondary to the reduction of edema. The sEMG might be used for quantitative evaluation of analgesics via assessment of neuromuscular reactions to analgesia.
