Dexamethasone Reduces the Incidence of Postoperative Nausea and Vomiting in Children Undergoing Endoscopic Adenoidectomy under General Anesthesia Without Increasing the Risk of Postoperative Hemorrhage.
BACKGROUND Postoperative nausea and vomiting (PONV) is a common complication of pediatric anesthesia, but the overall incidence of PONV in patients undergoing adenoidectomy is unknown. The aim of this controlled study was to compare the effect of dexamethasone administration with placebo to reduce PONV in children undergoing endoscopic adenoidectomy under general anesthesia. MATERIAL AND METHODS A randomized placebo-controlled study included 118 pediatric patients who underwent elective endoscopic adenoidectomy under general anesthesia. ⋯ In the first 24 hours following surgery, in Group D, the incidence of nausea and vomiting was 13% and 7%, respectively; in Group C, without pharmacological prophylaxis, the incidence of postoperative nausea and vomiting was 37%, and 21%, respectively. CONCLUSIONS A prospective controlled study in children undergoing endoscopic adenoidectomy under general anesthesia showed that dexamethasone (0.15 mg/kg) significantly reduced the incidence of PONV without increasing the risk of postoperative hemorrhage. Dexamethasone is a safe method for the prevention of PONV that may be recommended in pediatric anesthesiology.
