Implication

Randomized trial finds no difference in postoperative opioid needs between normothermic and hypothermic patients undergoing hysterectomy, indicating mild hypothermia does not alter analgesic demands.

Key Points

To determine whether intraoperative hypothermia alters postoperative opioid requirements and pain scores in patients undergoing lower abdominal surgery.
Prospective randomized trial involving 59 patients undergoing subtotal hysterectomy assigned to intraoperative forced-air warming or conventional blanket insulation without active warming.
Postoperative analgesia was delivered via patient-controlled analgesia with ketobemidone, monitoring analgesic demands, total consumption, pain scores, and core tympanic temperature for 48 hours.
Actively warmed patients maintained an up to 1 °C higher core temperature from 0.5 hours after anesthesia induction until nearly 2 hours postoperatively, but showed no differences in postoperative analgesic requirements or pain intensity compared to hypothermic controls.
Intraoperative blood loss was significantly reduced in actively warmed patients compared with hypothermic patients (186 ± 27 mL vs. 308 ± 47 mL; P < 0.05).
