Study summary

This randomized controlled trial aims to compare the effect of preoperative carbohydrate loading versus standard overnight fasting on postoperative recovery time in patients undergoing elective abdominal surgery. A total of 144 admitted patients will be randomly assigned to either receive a preoperative carbohydrate drink or follow routine fasting protocols. The primary objective is to evaluate differences in postoperative recovery time between the two groups. Secondary outcomes include length of hospital stay, postoperative complications, and patient comfort. The findings of this study may help optimize preoperative fasting guidelines and improve patient recovery outcomes.

Read the detailed description

Preoperative fasting has traditionally been practiced to reduce the risk of aspiration during anesthesia; however, prolonged fasting may lead to increased insulin resistance, patient discomfort, and delayed postoperative recovery. Recent evidence suggests that preoperative carbohydrate loading may improve metabolic response and enhance recovery after surgery.

This single-center randomized controlled trial will be conducted on 144 patients admitted for elective abdominal surgery. Eligible participants will be randomly allocated into two groups: the intervention group will receive a standardized preoperative carbohydrate drink within a defined time before surgery, while the control group will follow conventional fasting guidelines.

The primary outcome of the study is postoperative recovery time, assessed using clinically relevant recovery parameters. Secondary outcomes include length of hospital stay, incidence of postoperative complications, and patient-reported comfort measures.

Data will be collected prospectively during hospital stay and analyzed to determine whether preoperative carbohydrate loading provides significant benefits over standard fasting protocols. The results of this study may contribute to improving perioperative care practices and updating fasting guidelines in surgical patients.

Study arms

  • Experimental
    Pre operative carbohydrate Loading group

    Patients in this group will receive a preoperative carbohydrate-rich clear liquid drink before elective abdominal surgery to reduce insulin resistance, improve postoperative recovery, and decrease discomfort associated with prolonged fasting.

    Dietary Supplement: Patients will be given 400 mL of a carbohydrate-rich clear drink (10% daxtrosewater) approximately 2-3 hours before induction of anesthesia, according to ERAS guidelines.

  • Active comparator
    Standard preoperative fasting group

    Patients in this group will follow the routine preoperative fasting protocol as per hospital practice, including overnight fasting from solids and clear liquids according to standard anesthetic guidelines before elective abdominal surgery. No preoperative carbohydrate drink will be administered. Postoperative recovery outcomes will be compared with the intervention group receiving preoperative carbohydrate loading.

    Other: Standard pre operative fasting

    Most previous studies have evaluated preoperative carbohydrate loading in mixed surgical populations or in settings outside Pakistan. Limited local data exist specifically for elective abdominal surgery patients in a single-center Pakistani tertiary care hospital setting. Thisstudy focuses on comparing a standardized carbohydrate loading dose with conventional fasting and assessing its direct impact on postoperative recovery time in your local population. surgery patients specifically It uses a standardized carbohydrate loading dose It compares against the routinely practiced prolonged fasting protocol It is conducted in a single-center local hospital population, where local evidence is limited It focuses on postoperative recovery time as the primary clinical outcome

What researchers measure

Primary outcomes

  1. Post operative insuline resistance

    To evaluate the effect of preoperative oral carbohydrate loading compared with standard fasting on postoperative insulin resistance in patients undergoing elective abdominal surgery. Insulin resistance will be assessed by measuring fasting blood glucose and serum insulin levels preoperatively and postoperatively, and calculating insulin resistance using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).

    Time frame: 24 hours after surgery

Secondary outcomes

  1. Time to first oral intake

    To compare the duration from completion of surgery until the patient tolerates first oral intake (clear fluids or oral diet) between the preoperative carbohydrate loading group and the standard fasting group. This outcome reflects early postoperative gastrointestinal recovery and readiness for oral feeding.

    Time frame: 24 hours after surgery
