preOp A ready-to-drink, lemon flavoured carbohydrate drink for pre-operative dietary management of patients undergoing elective surgery. Suitable for use as part of Enhanced Recovery After Surgery (ERAS) programs: carbohydrate loading before surgery is recommended to improve patient outcomes including shorter length of stay and reduced post-operative insulin resistance. Safe to use up until 2 hours prior to anaesthesia: shortens pre-operative fasting period and improves patient wellbeing by reducing feelings of thirst, hunger and weakness pre- and post-operative. 25.2g carbohydrate/bottle (100% energy): induces insulin release during pre-operative carbohydrate feeding which promotes anabolic state and results in reduction in post-operative insulin resistance. Maltodextrin polymer composition: lower osmolality than pure glucose or other monomer solutions and contributes to increased gastric emptying rate.
