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]

A letter to the editor of the World Journal of Surgery discusses a recent study comparing the effects of different endotracheal tubes on postoperative sore throat (POST) in patients undergoing thyroidectomy. The study found that a neural integrity monitor electromyography endotracheal tube (NIM-EMG-ETT) resulted in a higher incidence and severity of POST compared to a standard endotracheal tube. However, the letter raises questions about the methodology and results of the study, including the lubrication of the tubes, the use of nerve blocks for analgesia, and the assessment of analgesic medication for POST. The letter also highlights the need to evaluate other outcomes, such as patient recovery and satisfaction, in future studies. [Extracted from the article]
