What complication can arise from OG/NG tube feeding?

Tube occlusion is a known complication that can arise from orogastric (OG) and nasogastric (NG) tube feeding. This occurs when the feeding tube becomes blocked, interrupting the flow of nutrition and hydration to the patient. Factors contributing to tube occlusion may include the use of viscous feeding formulas, inadequate flushing of the tube, or the presence of medication residues. If a tube becomes occluded, it may require replacement or specific interventions to clear the blockage, ultimately leading to a delay in feeding and potential adverse nutritional consequences for the patient.

Other options, while relevant in broader contexts, are not typically recognized as direct complications of tube feeding in the same way. For example, gastrointestinal perforation can occur in rare and severe cases but is not a common complication associated with tube feeding. Kidney dysfunction and elevated blood pressure are more systemic issues that are generally outside the direct effects of feeding tube placement or function. Therefore, tube occlusion is most closely linked to the process of providing nutrition via an OG or NG tube.
