Preoperative Carbohydrate Loading in Diabetic Patients Undergoing Elective Abdominal Surgery

Summary

This study evaluates the effect of preoperative carbohydrate loading on early postoperative recovery in patients with type 2 diabetes mellitus undergoing elective abdominal surgery. Traditionally, patients fast before surgery, which can increase insulin resistance, delay recovery, and worsen postoperative outcomes. Preoperative carbohydrate drinks may reduce surgical stress and improve recovery, but concerns exist regarding blood glucose control and gastric emptying in diabetic patients.

In this randomized, double-blind clinical trial, 120 eligible patients will be assigned to three groups: nondiabetic control, nondiabetic with carbohydrate load, and diabetic with carbohydrate load. Patients will receive either a carbohydrate-rich drink or control solution before surgery. Preoperative gastric residual volume will be measured using ultrasound to assess aspiration risk. Blood glucose levels will be measured before and after carbohydrate intake. Postoperative outcomes including metabolic and inflammatory response, nausea and vomiting, length of hospital stay, and time to independent ambulation will be recorded.

The study aims to determine whether preoperative carbohydrate loading is safe and beneficial for diabetic patients undergoing elective abdominal surgery.

Conditions

Interventions

BEHAVIORAL

Standard Preoperative Fasting With Water

Participants receive 100 ml yogurt mixed with approximately 42 g honey at midnight before surgery. Two hours before induction of anesthesia, they receive 200 ml of clear water. No carbohydrate-rich clear drink is administered preoperatively. This represents the standard preoperative fasting protocol used in the control group.

BEHAVIORAL

Preoperative Oral Carbohydrate Loading

Participants receive 100 ml yogurt mixed with approximately 42 g honey at midnight before surgery. Two hours before induction of anesthesia, they receive 200 ml of a clear carbohydrate drink consisting of 200 ml water with two spoonfuls (approximately 42 g) of honey dissolved. This intervention is administered preoperatively to reduce perioperative insulin resistance and improve metabolic response.
