Background Carbohydrate loading is a main component included in many ERAS protocols to attenuate the body's metabolic stress response during surgery. There are several different doses of carbohydrates and times of administration of the carbohydrate drink currently in practice.
Objectives Scoping review evaluating the dosing and administration of carbohydrate drinks prior to abdominal surgery.
Search methods Search conducted in Cochrane Library, PubMed, CINAHL Complete, Medline Complete, and Joanna Briggs Institute.
Selection criteria Systematic reviews, randomized controlled trials, quasi-experimental studies, and retrospective observational studies available in full text, English language, published between January 2002 and December 2022, peer reviewed, and only human subjects. All studies had to include dose of carbohydrates.
Data collection and analysis 27 studies found that matched with inclusion criteria. Studies were reviewed, placed into a table, and synthesized.
Main results Most common carbohydrate dose was a morning dose of 400 mL 2 hours prior to induction of anesthesia. 400 mL 2-3 hours or 3 hours prior to induction of anesthesia was also common. Positive results showing attenuation of the metabolic stress response were seen over multiple doses and times, showing it can be advantageous to provide any level of carbohydrates prior to surgery.
Authors' conclusions Carbohydrate loading is a safe, feasible, and effective implementation to improve the comfort of patients and attenuate the metabolic response during surgery. | |
