What is the primary risk associated with extravasation?

The primary risk associated with extravasation is skin irritation and blistering. Extravasation occurs when intravenous fluid or medication inadvertently leaks into the surrounding tissue instead of flowing into the bloodstream through the vein. This leakage can lead to localized tissue damage as the substance, particularly if it's a vesicant (a substance that can cause blistering), irritates the surrounding tissues.

When extravasation occurs, the body's response can include inflammation and localized damage, leading to symptoms such as redness, swelling, skin irritation, and potentially blistering as the tissue integrity is compromised. The severity of the damage may depend on the type of fluid that has extravasated, the volume, and the duration of the exposure. Consequently, managing extravasation promptly is crucial to minimize tissue injury and promote healing.
