T80-T88: Complications of surgical and medical care, not elsewhere classified

T80: Complications following infusion, transfusion and therapeutic injection

The group of conditions classified under "Complications following infusion, transfusion and therapeutic injection" encompass a range of situations that can occur after medical treatments such as receiving an intravenous (IV) drip, a blood transfusion or a medical injection. These complications can span from allergic responses and infections to poor reactions at the site where the treatment was given. Allergic reactions may appear as rash, itchiness, swelling or difficulty in breathing immediately or a few hours after the treatment. Infections could be due to the entry of germs at the treatment site, causing fever, redness, swelling or pus. Reactions at the treatment site might include inflammation, bleeding, or discomfort. These conditions can manifest abruptly after treatment or arise after a period of time, and they can affect various body systems based on the nature and severity of the complication.
