Extravasation, the escape of intravenous fluids or medications into the surrounding tissue, occurs when a blood vessel is compromised. This commonly manifests as localized swelling, discomfort, and potentially bruising at the injection site. For instance, if a chemotherapy drug intended for intravenous delivery leaks into the subcutaneous space, it can cause significant tissue damage.
Recognizing and promptly managing extravasation is crucial to minimize patient discomfort and prevent more serious complications, such as tissue necrosis or compartment syndrome. Historically, the consequences of this occurrence were often overlooked, leading to prolonged patient suffering and, in some cases, requiring surgical intervention. Awareness and established protocols have improved patient outcomes significantly.
