概要
OBJECTIVE
To evaluate the prophylactic use of dexamethasone for reducing postoperative nausea and vomiting (PONV) and analgesic use after gynecological laparoscopic surgery.
METHODS
In a prospective randomized, double-blind, placebo-controlled trial, 90 women received either intravenous placebo, 4 mg dexamethasone or 8 mg dexamethasone at the end of surgery. PONV and analgesic requirements were evaluated.
RESULTS
The rate of patients experiencing PONV within 24 h after anesthesia was 53% in the 4 mg dexamethasone group (P=0.3) and 20% in the 8 mg dexamethasone group (P=0.001), compared with the placebo group (63%). Requests for indomethacin to relieve intolerable pain were less in patients in the 8 mg dexamethasone group compared with the 4 mg dexamethasone (P=0.047) or placebo (P=0.029) groups.
CONCLUSIONS
Prophylactic use of 8 mg dexamethasone is effective for reducing PONV and analgesic requirements after gynecological laparoscopic surgery.
