Which type of infiltration is considered the worst during treatment?

Venous infiltration is considered the worst type during treatment because it can lead to significant complications in patients, especially in the context of fluid management. Infiltration refers to the inadvertent administration of a solution into the surrounding tissue rather than into the intended vein. With venous infiltration, the potential for swelling and tissue damage is heightened due to the high volume of blood that is typically returned from veins and the potential impact of fluid overload.

In the case of venous infiltration, the patient's overall cardiovascular status can be compromised, with the risk of edema occurring rapidly. If the infiltrated fluid contains medications or solutions that are irritants, this can result in further tissue irritation or necrosis.

In contrast, while arterial and capillary infiltrations can also lead to complications, they typically do not pose as immediate a systemic risk as venous infiltration. Arterial infiltration is usually more serious because it can compromise blood flow, but it is less common in practice compared to venous infiltration when administering treatments like IV fluids or medications. Capillary infiltration usually refers to smaller vessels and does not generally cause severe systemic issues. Lymphatic infiltration, while it can indicate fluid accumulation, is less directly related to the issues caused by intravenous therapy.

Thus, venous
