What is a common sign of infiltration?

Swelling and hardness at the insertion site is a common sign of infiltration. Infiltration occurs when intravenous fluid or medication leaks into the surrounding tissues instead of being delivered into the bloodstream as intended. This leads to localized edema or swelling, as the escaped fluid collects in the tissue. Additionally, the area may become firm or hard to the touch due to the accumulation of fluid.

Recognizing these signs is crucial for prompt intervention, as untreated infiltration can lead to more serious complications, such as damage to surrounding tissues or even necrosis. Monitoring the infusion site for changes, such as swelling or hardness, is an important practice in intravenous therapy to ensure patient safety and effective treatment.
