Maltodextrin vs Sugar Water for Pre-Surgery Carbohydrate Loading in Older Adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind trial compares two preoperative carbohydrate drinks in adults aged 60 and above scheduled for elective lower limb orthopedic surgery under neuraxial anesthesia. Participants receive 400 mL of either maltodextrin or sugar water 2 hours before anesthesia, with gastric volume measured by ultrasound and blood glucose monitored at specified times. The study aims to see which drink alters gastric fluid and glucose responses more favorably, within a controlled, parallel-group design. Outcomes include gastric volume before and after drinking, and glucose levels up to 6 hours post-surgery, alongside basic perioperative data. The trial is conducted at a hospital in Denpasar, Indonesia, with double-blinding maintained through identical containers and labeling.
