What defines a low output fistula in terms of daily output?

A low output fistula is typically defined as one that produces less than 200 mL of fluid per day. This definition is significant for several reasons. Low output fistulas can often be managed more conservatively in terms of fluid replacement and nutritional support. In clinical practice, recognizing the volume of output is essential because it informs the care plan and the strategies used to promote healing and prevent complications such as dehydration or electrolyte imbalances.

While any output volume can indicate varying needs for management and intervention, outputs below 200 mL are generally considered low and suggest a different level of urgency as compared to outputs of 500 mL or more, which are classified as high output. Understanding these classifications is crucial for healthcare providers, particularly in the context of caring for patients with ostomies and fistulas, as it influences decisions about wound care, nutritional support, and the overall approach to managing these patients.
