If "coffee ground" material is noted in an NG tube, what does this indicate?

When "coffee ground" material is observed in an NG tube, it indicates the presence of altered blood. The term "coffee ground" describes the appearance of digested blood that has been in contact with gastric acid, which changes its color and texture. This typically suggests that there has been some bleeding in the upper gastrointestinal tract, such as from a peptic ulcer or gastritis. The blood has been partially digested, giving it a dark, granular appearance reminiscent of coffee grounds.

In contrast, normal digestive fluids would not have this characteristic appearance, and inadequate suctioning would not typically result in coffee ground-like material. Additionally, an infection would not specifically produce this type of material, as it is more associated with bleeding rather than infectious processes. Recognizing the significance of “coffee ground” material is crucial in nursing care as it necessitates further investigation and appropriate medical intervention.
