The document discusses a study that evaluated the effects of dexmedetomidine on postoperative pain and opioid consumption in patients undergoing abdominal hysterectomy. The study found that patients who received dexmedetomidine intraoperatively required less opioids in the first 24 hours after surgery and experienced less pain compared to patients who did not receive dexmedetomidine. Dexmedetomidine was well tolerated with few side effects reported.
