Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients randomised to the intervention arm of the study will be asked to drink 800ml of the CHO (Nutrica PreOp [registered trademark] solution) between 1900 and 2400 hours on the night before surgery and to have no solid food from midnight. The beverage is a clear fluid with 50 kcal per 100 ml, 290 mOsm/kg, and a pH of 5.0). In accordance with the RBWH protocol, other clear fluids may be taken during the night. At 0500 hours on the morning of surgery, patients will be asked to drink a further 400mls of the solution and to record any side-effects caused by the drink. No further fluids are permitted before surgery.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
If a patient meets all inclusion and no exclusion criteria, the research nurse will obtain group allocation via a telephone service.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use a computer generated randomised list to determine allocation sequence.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Summary
Brief summary
The literature suggests that a carbohydrate rich
beverage before surgery positively affects postoperative recovery and improves subjective patient wellbeing.
The positive effect of carbohydrate rich oral fluid intake on perioperative urine output and fluid and electrolyte balance has also been shown. Although the metabolic and electrolyte advantages of using a carbohydrate rich
preoperative beverage have been demonstrated, there is less information about whether these advantages translate into improved postoperative clinical outcomes, such as whether preloading with a carbohydrate drink reduces hospital length of stay. The current study has been designed to establish the efficacy of preoperative
carbohydrate drink in shortening time to discharge in a prospective randomised clinical trial for gastroenterology patients undergoing elective bowel surgery.
