NCT07519057

Brief Summary

The aim of the study is to evaluate the effect of preoperative oral carbohydrate loading on postoperative outcomes in liver transplant recipients. The results of this study may contribute to improving recovery after liver transplantation and shortening postoperative hospital stay in these patients. Participants will be randomly assigned to either the study group or the control group. Patients assigned to the study group will receive 400 mL of a carbohydrate beverage (Nutricia preOp®), to be consumed up to 2 hours before the anesthesia induction. Patients assigned to the control group will receive 400 mL of a placebo administered in an identical manner as in the study group. Participants will not be informed which group they have been assigned to. In the postoperative period, routine laboratory and imaging tests will be performed, and their results will be used to assess the effects of the intervention. Follow-up of the patient's clinical course is planned for up to 30 days after surgery. The schedule of follow-up visits will not differ from standard clinical practice.

Outcome Measures

Primary Outcomes (1)

  • Hospital-Free Days at 30 (HFD30)

    The number of days a patient is both alive and discharged from the hospital within the first 30 days after transplantation.

    From the date of liver transplantation up to 30 days post-surgery

Secondary Outcomes (5)

  • Time to First Oral Intake

    From the end of surgery up to hospital discharge, assessed up to 30 days

  • Time to Return of Gastrointestinal Function

    From the end of surgery up to hospital discharge, assessed up to 30 days

  • Incidence of Postoperative Infections

    From the date of liver transplantation up to 30 days post-surgery

  • Length of ICU Stay

    From the date of ICU admission until transfer to a surgical ward or hospital discharge (up to 30 days)

  • Incidence and Severity of Postoperative Complications

    From the date of liver transplantation up to 30 days post-surgery

Study Arms (2)

Preoperative Oral Carbohydrate Loading Group

EXPERIMENTAL

Participants will receive 400 mL of a preoperative oral carbohydrate drink (Nutricia preOp®), with intake completed 2 hours prior to anesthesia induction.

Dietary Supplement: Preoperative Oral Carbohydrate Loading

Placebo Group

PLACEBO COMPARATOR

Participants will receive 400 mL of a water-based, sensory-similar placebo drink, with intake completed 2 hours prior to anesthesia induction. The placebo contains a low concentration of sugar for flavoring to mimic the taste of the carbohydrate drink.

Dietary Supplement: Placebo

Interventions

Preoperative Oral Carbohydrate Loading will be administered as 400 mL of Nutricia preOp® beverage. It is an iso-osmolar, maltodextrin-based carbohydrate solution containing 12.6 g of carbohydrates per 100 mL.

Preoperative Oral Carbohydrate Loading Group
PlaceboDIETARY_SUPPLEMENT

A water-based solution (400 mL) containing a low concentration of sugar for flavoring to match the taste of the experimental intervention, with no intended therapeutic or nutritional effect.

Placebo Group
