Identification of an extravasal injection
- A burning, stinging pain or other acute change of the puncture site.
- Local redness or inflammation of the skin around the puncture site.
- The infusion rate slows/stops.
- Swelling of the puncture site.
Extravasation has probably also occurred if blood cannot be aspirated, resistance is felt on the plunger when a syringe is used, and/or there is no current if the drug is infused.
