Ảnh hưởng của uống dung dịch giàu carbohydrate trước phẫu thuật đến tồn dư dịch dạ dày, đường máu và nôn - buồn nôn sau phẫu thuật lồng ngực

Abstract

Objective: To evaluate the effects of oral preoperative carbohydrates solutions up to 2 hours before surgery on gastric juice residues, blood sugar, and vomiting-nausea after thoracic surgery. Subject and method: A randomized controlled clinical trial on 120 patients undergoing thoracic surgery at Bach Mai Hospital. Eligible patients were randomly assigned to 2 groups: Group I received 2 bottles of carbohydrate-rich solution, and group II fasted from 22 hours the previous day and drank the solution > 2 h before surgery. Gastric residual volume after induction of anesthesia, blood glucose, and postoperative nausea and vomiting were assessed and recorded. Result: Preoperative carbohydrate solution supplementation did not make a difference in the amount of gastric residual fluid before surgery compared with fasting alone (p>0.05). Levels of thirst, blood sugar in the study group were lower than those in the control group at the time points before surgery/30 minutes after induction of anesthesia and 2 hours after surgery (p<0.05). Symptoms of vomiting and nausea did not differ between the two groups at the time before surgery and after surgery (p>0.05). Conclusion: Drinking a carbohydrate-rich solution before thoracic surgery is safe, does not increase gastric residual fluid, reduce thirst, vomiting-nausea, and does not increase blood sugar after surgery.
