Does perioperative intravenous dextrose reduce postoperative nausea and vomiting? A systematic review and meta-analysis.

Perioperative dextrose-containing fluid administration has been used as a non-pharmacologic preventive measure against postoperative nausea and vomiting (PONV), a common and distressing complication of anesthesia. However, its efficacy remains unclear as previous studies reported inconsistent results. Our objective was to compare dextrose-containing fluid with non-dextrose-containing fluid in terms of PONV for 24 hours after surgery under general anesthesia. The effects of dextrose according to different types of surgery and the fluid volume were also examined.
