Randomized Controlled Trial Comparative Study Clinical Trial
Gastric residual volumes in critically ill paediatric patients: a comparison of feeding regimens.
This study examined the effect of gastric feeding regimens, either continuous or intermittent, on fourth hourly gastric residual volumes (GRV) in a group of critically ill paediatric patients where delayed gastric emptying is defined as a GRV greater than 5ml/kg. A randomised controlled trial was conducted in a tertiary paediatric intensive care unit (PICU), with 45 participants being randomly assigned to either the continuous (n=22) or intermittent (n=23) gastric feeding groups. Participants remained in the assigned group for the duration of the study and, fourth hourly, GRV were assessed to monitor the incidence of delayed gastric emptying. ⋯ The provision of enteral nutrition via the gastric route is a common treatment in the PICU, and GRV are frequently used as a measure of gastric tolerance. The result of this analysis provides some support for the theoretical definition of delayed gastric emptying being >5ml/kg. However, further work is required to confirm this finding and to determine its relevance when providing enteral nutrition to the critically ill paediatric patient.
