injection site reaction

Also found in: Acronyms.

injection site reaction

An allergic, histaminic, or traumatic response of the skin and subcutaneous tissues to any substance introduced with a needle.

Patient care

The injection site should be carefully monitored for redness, swelling, necrosis, or purulence. The size of any injury should be measured and the patient's level of pain assessed. Management may depend on the nature of the introduced substance. In mild cases, topical application of a cold pack may alleviate symptoms. When a reaction occurs at the site of a vesicant injection (e.g., in patients receiving cancer chemotherapy), close monitoring by a physician or the injection of local antidotes may be required. Reactions that result in infection or necrosis may need to be treated with antibiotics or with surgical débridement.
