Medicine and fluids are often given directly into a blood vessel through an I.V. (intravenous) tube, or catheter. Extravasation (say "ex-truh-vuh-SAY-shun") is leakage of fluid in the tissues around the I.V. site. It happens when the catheter has come out of the blood vessel but is still in the nearby tissue. It may also happen if the blood vessel leaks because it is weak or damaged. The fluids collect in the tissues around the I.V. site rather than staying in the blood vessel. The buildup of fluid can cause tissue damage at the site. The leakage also prevents the medicine or fluid from being sent into the bloodstream for treatment as intended.
Symptoms of I.V. extravasation include:
To treat I.V. extravasation, the nurse will remove the I.V. and clean the site. If needed, another I.V. will be inserted at a new site elsewhere on the body.
The I.V. site will be raised above the level of the body, if it's on the arm or leg. This keeps the fluid from pooling in one place and helps prevent tissue damage.
The I.V. site will be watched for signs of tissue damage or infection. With treatment, the swelling should go down day by day.
