When assessing an IV site, what does redness and warmth indicate?

Redness and warmth at an IV site are commonly associated with phlebitis, which is inflammation of the vein. This condition often occurs as a reaction to the catheter or the infusate, leading to localized symptoms such as redness (erythema), warmth, swelling, and sometimes pain. These signs are indicative of the body's inflammatory response to irritation or trauma in the vein, which can be triggered by factors such as the type of catheter used, the duration of IV therapy, or the nature of the fluid being infused.

Recognizing these symptoms is vital for timely intervention, as untreated phlebitis may progress to more severe conditions, including thrombophlebitis or systemic infections. It’s important to assess the IV site regularly and to take appropriate action if phlebitis is suspected, such as discontinuing the IV and applying warm compresses to the area.
