When to Check Gastric Residuals in Preterm Infants

December 1, 2017 7:00 am

A recent study (A Riskin et al. J Pediatr 2017; 189: 128-34) indicates that routine testing of gastric residual volumes is not needed. In this study of preterm infants ≤34 weeks gestation 239 infants were studied prior and 233 studied after dropping routine checks of gastric residuals.

Key findings:

• Selective evaluation of gastric residuals was associated with achieving full enteral nutrition 1 day earlier
• The rate of NEC (stage ≥2) was actually lower in the selective evaluation group (1.7% vs 3.3%) compared to the historic control group

Selective checking of gastric residuals was prompted by the following:

• abdominal distention
• vomiting or large regurgitation
• bilious regurgitation or emesis
• abnormal behaviors: restlessness, somnolence or apathy
• increased apnea/bradycardia
• change in vital signs

While checking gastric residuals had been used to determine feeding intolerance and/or development of necrotizing enterocolitis, this study indicates that routine evaluation is not necessary.

My take: This study challenged a common NICU practice and found that routine assessment of gastric residuals is not needed; selective checking of gastric residuals is sufficient.
