Proper regulation of the physiologic process during feeding is critical for an effective response to the demands of oral feeding. For high-risk infants, oral feeding can be physiologically stressful and often associated with cardiovascular distress. This stress response can lead to a physiologic circulatory redistribution diverting blood away from the gastrointestinal (GI) tract and toward the vital organs, such as the brain, which may cause difficulties with digestion, poor gut motility, and increased feeding intolerance. Near-infrared spectroscopy has been used for the noninvasive determination of mesenteric hemodynamic changes related to various physiologic and pathological conditions; however this measure has not been investigated in relation to oral feeding.

Learning Objectives:

At the conclusion of this presentation, the learner will be able to:

Understand physiologic challenges high-risk infants experience during oral feeding
Describe patterns of splanchnic and cerebral oxygenation that are associated with feeding stress in high-risk infants
List three infant biological functions associated with different patterns of splanchnic and cerebral oxygenation
Summarize how splanchnic and cerebral oxygenation can be used as a clinical tool to assess problematic feeding in high-risk infants
