Effect of not monitoring residual gastric volume on ventilator-associated pneumonia

Reignier 2013 trial design and results
Design Multicentre randomised non-inferiority trial
Treatment No monitoring of residual gastric volume
Control Routine monitoring of residual gastric volume
Population 449 adults receiving mechanical ventilation and early enteral feeding
Follow-up 90 days
Primary endpoint Ventilator-associated pneumonia
Result Ventilator-associated pneumonia occurred in 38 of 227 (16.7%) in the no-monitoring group and 35 of 222 (15.8%) in the monitoring group — difference 0.9%, 90% CI -4.8% to 6.7%, meeting non-inferiority.
Secondary endpoints Vomiting, calorie delivery, feeding intolerance, mortality

Among adults requiring mechanical ventilation and receiving early enteral nutrition, the absence of gastric volume monitoring was not inferior to routine residual gastric volume monitoring in terms of development of VAP.

How it has aged

A de-implementation result that removes a nursing ritual performed millions of times a day worldwide. Not monitoring also improved calorie delivery, since residuals were the usual reason feeds were stopped.
