What type of infiltration is considered the most severe in a dialysis context?

In the context of dialysis, venous infiltration is considered the most severe type of infiltration. This is primarily because it involves the disruption of blood flow returning to the heart via the veins, which can lead to more serious systemic complications compared to other types. Venous infiltration can result in significant hematoma formation and can increase the risk of complications like infection, prolonged bleeding, and even thrombosis in the affected area.

Furthermore, since the veins are responsible for carrying deoxygenated blood back to the heart, any leakage in this system can lead to a compromised hemodynamic state for the patient, requiring careful monitoring and potential intervention. The severity of venous infiltration demands more immediate medical attention compared to arterial or capillary infiltrations, which may not have as profound an impact on overall circulation.

Understanding the implications of venous infiltration helps healthcare professionals prioritize management strategies to prevent complications and ensure patient safety during dialysis.
