Three-Part Question:
In [children with gastro-enteritis] is [gradual introduction of feeding better than immediate normal feeding] with regards to [symptom control and time to resolution]?
Clinical Scenario:
A mother with her 11 month old daughter attends the surgery. The child has gastro-enteritis and is mildly dehydrated. Mum has been starving the child the last 24 h as "everything comes back up". She has read this and also to avoid milk feeds in her health manual at home. Having read a paper once on continueous milk feeding as opposed to gradual regrading of milk, I decide to look which approach would be better.
Search Strategy:

Dugdale A, Lovell S, Gibbs V, et al. 1982, Australia 59 inpatients older than 6 months (average 22 months) with acute gastro enteritis were given clear fluids and then allocated either to half strength milk for 24 h and then full strength milk and food or immediate normal milk and food RCT Weight During first 24 h of refeeding immediate group lost 0.02 (0.25) kg and the graduated group lost 0.14 (0.21) p> 0.05 Small numbers

Complications No significant diffences re complications
Author Commentary:
Nearly all studies show no significant difference in length of symptoms and hospital stay. Two larger studies showed a significant increase in weight in the initial stages with immediate full strenth feeding. One larger study also showed an increase in severity but not in length of diarrhoea with immedaite feeding. This was associated with faster weight gain. One study showed benefit of lactose free feeds in severe dehydrating gastroenteriris. One smaller study showed more complicated clinical courses with immediate feeding, this was a small study and 20% of the children needed intravenous hydration possibly related to a more severe illness. In two smaller studies children had solids as well and did not do worse.
Bottom Line:
In children with gastroenteritis, gradual reintroduction of feeding is not better than immediate normal feeding with regards to time to resolution and symptom control.
