What is a common symptom of extravasation?

Swelling around the catheter site is a common symptom of extravasation, which occurs when intravenous fluids or medications leak into the surrounding tissue instead of the intended vascular space. This leakage can lead to a localized inflammatory response, resulting in swelling, redness, and sometimes pain or discomfort at the site. The accumulation of fluid in the interstitial space causes the characteristic swelling, making it a key indicator of extravasation.

In this context, while rapid heartbeat, chest pain, and fatigue may be symptoms associated with various medical conditions or reactions, they are not typically linked to extravasation specifically. Instead, these symptoms are more commonly associated with systemic responses or complications, whereas swelling at the catheter site directly indicates the localized issue of fluid leakage. Understanding this distinction is important for effective monitoring and management of patients receiving intravenous therapy.
