Which factor is a major risk factor related to gastric content?

• A. Persistent high gastric residual volumes
• B. Age
• C. Tracheal intubation
• D. Large diameter feeding tubes

Answer: (A)

High residual volumes mean the stomach isn’t emptying properly, leaving more gastric content that can regurgitate into the esophagus and be aspirated into the lungs during feeding. This direct link to the amount of contents in the stomach makes persistent high gastric residual volumes the major risk factor related to gastric content. Age and tracheal intubation influence aspiration risk through other pathways, and large diameter feeding tubes don’t inherently increase the risk of gastric content in the same direct way. When GRV stays high, clinicians often pause feeds per protocol and consider prokinetics or a switch to post-pyloric feeding to reduce aspiration risk.
