An IV, short for “intravenous,” is a familiar medical device used by doctors and nurses to administer various medications and other fluids to patients by inserting a needle or tube directly into the patient’s vein. Once the IV is inserted into the vein, it typically is taped to the skin to prevent it from moving or otherwise coming loose. If an IV becomes dislodged from the vein but stays under the patient’s skin, the medication being dispensed can be harmful to the surrounding tissue. This is called an IV extravasation.
If the patient is awake when the extravasation occurs, they usually feel immediate pain or discomfort and can quickly notify a doctor or nurse of the problem before significant harm is caused. However, if the extravasation occurs while the patient is unconscious (for example due to anesthesia or other sedation), the harmful medication can be dispensed into the patient’s tissue for a long period of time, causing significant injury to the patient, including tissue damage and necrosis (death of the tissue).
As a result, it is important that when a patient who has an IV is unconscious, the doctors and nurses regularly check the IV to ensure that no extravasation has occurred and quickly stop the dispensation of medication if it does occur.
