What might swelling at the IV site indicate?

Swelling at the IV site is a significant sign that may suggest potential infiltration, which occurs when IV fluid leaks into the surrounding tissue instead of staying within the vein. Infiltration typically happens when the catheter is not properly positioned within the vein, which leads to fluid accumulation in the interstitial space. This can lead to discomfort for the patient, and if it continues, may also result in skin damage or tissue injury.

While other answers may refer to aspects of IV therapy, they don't accurately capture the implications of swelling. Proper fluid administration and successful venous access generally do not present with swelling; instead, they are indicated by adequate blood return and an absence of discomfort. Therefore, when swelling is observed, it is essential to assess for infiltration and take appropriate actions to address it, such as discontinuing the IV line and possibly relocating the IV access site.
