Letter to the Editor: Effect of preoperative carbohydrate drink and postoperative chewing gum on postoperative nausea and vomiting in patients undergoing day care laparoscopic cholecystectomy: A randomized controlled trial.

A letter to the editor of the World Journal of Surgery discusses a randomized controlled trial that examined the effects of preoperative carbohydrate drinks and postoperative chewing gum on postoperative nausea and vomiting (PONV) in patients undergoing day care laparoscopic cholecystectomy. The study found that these interventions significantly reduced the severity of PONV and the need for antiemetics. However, the letter raises concerns about the methodology and results of the study, including the lack of information on preoperative risk factors, intraoperative fluid volumes, and the use of analgesics and antiemetics. The authors argue that addressing these issues would improve the interpretation of the study's results. [Extracted from the article]
