Key result
Carbohydrate-glutamine beverage yields similar 120-minute residual gastric volume compared to carbohydrate alone or fasting.
Why the study?
Does adding glutamine to a carbohydrate-enriched beverage increase residual gastric volume in healthy volunteers?
RCT (n=20)
crossover
Does adding glutamine to a carbohydrate-enriched beverage increase residual gastric volume in healthy volunteers?
Absolute Event Rate: 15.63% vs 16.32%
p-value: p=>0.05
Adding glutamine to a preoperative carbohydrate beverage does not delay gastric emptying or increase residual gastric volume compared to fasting or carbohydrate alone.
No takes yet. Share an insight, caveat, or question.
Supports glutamine addition to preoperative carbohydrate drinks without aspiration risk; extends ERAS safety data in healthy volunteers.
Gomes et al. (2017) conducted an RCT in healthy volunteers (n=20). Carbohydrate plus glutamine (CHO-GLN) beverage vs. Carbohydrate (CHO) beverage alone (12.5% maltodextrin) was evaluated on Residual gastric volume at 120 minutes (p=>0.05). Ingestion of a carbohydrate-glutamine beverage resulted in a residual gastric volume at 120 minutes (15.63 mL) similar to carbohydrate alone (16.32 mL) and an 8-hour fast (13.56 mL; P>0.05).
