Fluid diet - preoperative oral diabetes

This document is part of the ACI Diet Specifications for Adult Inpatients. It is not to be used for patient education.

Aim

To continue oral fluids for people with diabetes until 2 hours before a procedure to replace or maintain the body’s water balance and leave minimal residue in the stomach.

Characteristics

Only fluids that are rapidly cleared from the stomach. All liquids containing fat, protein, and insoluble fibre are excluded. Carbohydrate containing fluids are also excluded to improve perioperative glycaemic control.

Indications

Preparation of patients with diabetes for procedures involving anaesthesia or sedation. This diet can be used up to 2 hours prior to the procedure. Pre-operative oral fluids can improve postoperative wellbeing and clinical outcomes.

Nutritional adequacy

This diet is inadequate in all nutrients and should not be used for more than 12 hours.

Precautions

Patients may not receive a menu. This diet is not suitable for patients on thickened fluids.

Patients without diabetes should be ordered Fluids - Preoperative Oral.

Some patients with diabetes may require small amounts of carbohydrate-containing oral fluids to correct hypoglycaemia.

This should be determined on a case-by-case basis following local protocols.

Paediatrics

Suitable for use in paediatrics when combined with an age-appropriate diet.
