COMPARISON OF GASTRIC FLUID VOLUME AFTER INGESTION OF MALTODEXTRIN 12,5% 1 HOUR AND 2 HOURS IN CHILDREN

Abstract

Background: Allowing children to ingest clear fluids up to 1 hour before surgery instead of 2 hours has not yet reached a consensus worldwide. Studies on gastric residual volume after 1 hour of drinking clear liquid in children have shown different results.

Objective: Determine the gastric fluid volume and the proportion of children with stomachs at high risk of aspiration at 1 hour and 2 hours after ingesting maltodextrin 12.5%.

Methods: Prospective cohort study on children from 3 to 12 years old who fasted before the elective procedure. Children ingested 3 ml/kg maltodextrin 12,5% and had stomach ultrasound after 1 hour and 2 hours to qualitatively and quantitatively assess the residual gastric fluid.

Results: A total of 76 children were included in the analysis. The mean gastric fluid volume after 1 hour of ingestion was 0.7 ± 0.2 ml/kg, and after 2 hours was 0.6 ± 0.2 ml/kg. The proportion of children with stomachs at high risk of aspiration at 1 hour and 2 hours after ingesting maltodextrin 12.5% is 0%.

Conclusion: In healthy children who ingested 3 ml/kg of 12.5% maltodextrin, the gastric fluid volume at 1 hour after ingestion was 0.7 ± 0.2 ml/kg, and at 2 hours after ingestion was 0.6 ± 0.2 ml/kg. The proportion of children with stomachs at high risk of aspiration was 0% at both times.
