What indicates the presence of thrombosis in an extremity?

The presence of thrombosis in an extremity can be indicated by slowed or stopped infusion along with tenderness. When a thrombus forms in a vein, it can obstruct blood flow, leading to issues with the infusion of IV fluids or medications. The tenderness felt in the area where the thrombus is located is also a significant symptom, as the surrounding tissues may become inflamed or irritated due to the blockage and the resultant changes in blood flow.

Increased temperature in the area may suggest inflammation or infection, but it is not specific to thrombosis. Bruising and swelling can be associated with various conditions, including trauma or venous insufficiency, rather than specifically indicating thrombosis alone. Elevated blood pressure does not directly relate to the presence of thrombosis in an extremity and can be influenced by numerous other factors unrelated to venous occlusion. Thus, the combination of a slowed or stopped infusion pattern and tenderness provides a clear indication that thrombosis may be present.
