Summarize findings from published research regarding the clinical variables that contribute to aspiration risk in tube-fed critically ill patients.
Conducted a targeted literature search evaluating potential risk factors for pulmonary aspiration in tube-fed, critically ill populations.
Assessed factors including patient level of consciousness, supine positioning, nasogastric tube presence and bore size, tracheal intubation, and continuous versus bolus feeding delivery.
Decreased level of consciousness and sustained supine body positioning were consistently identified as major, independent risk factors for aspiration.
Evidence regarding the influence of nasogastric tubes and tube bore size remained equivocal, with insufficient data to justify routine use of small-bore tubes for aspiration prevention.
Continuous formula delivery demonstrated stronger evidentiary support than bolus or intermittent feedings for reducing aspiration complications in high-risk patients.
