Is this trial a fit for you?

Likely a good fit

Adults (18+) undergoing elective liver transplantation at the Medical University of Warsaw with grafts from brain-dead donors and MELD < 35.

Probably not a fit

Patients with acute liver failure, insulin-dependent diabetes, gastroparesis, mechanical bowel obstruction, or recent liver retransplantation may not benefit.

What this trial studies

In this randomized, controlled trial, adults undergoing elective liver transplantation are assigned to receive a 400 mL carbohydrate drink (Nutricia preOp) up to two hours before anesthesia or a placebo. The primary question is whether preoperative carbohydrate loading improves postoperative recovery and shortens ICU stay and time to oral intake and GI function. Participants are followed for 30 days after surgery with routine labs and imaging to assess outcomes. Randomization is 1:1 with a pre-specified 434-patient sample size; blinding is maintained for participants and study staff. No biological samples are collected for this trial.

Why it matters

Potential benefit: If successful, patients may experience faster recovery and shorter hospital stays after liver transplantation.

How similar studies have gone: Other perioperative carbohydrate loading studies in surgical populations have shown potential benefits; applicability to liver transplant patients requires confirmation.
