Y48.4: Anaesthetic, unspecified

Anaesthetic complications are medical conditions that transpire due to the use of anesthesia, be it local, regional, or general, during medical procedures or surgical operations. These complications can occur because of an individual's unique physiological response to anaesthetics or due to an error in the administration of the anaesthetic. Complications may present with various symptoms such as nausea, vomiting, sore throat, confusion, and, in some rare cases, severe reactions like breathing difficulties or allergic reactions. These symptoms might occur immediately during the anesthesia administration or might present postoperatively. The severity of the reaction can vary, from transient and mild symptoms, that resolve without intervention, to severe, life-threatening reactions like anaphylactic shock or malignant hyperthermia. Note that anaesthetic complications are not classified by the type of anaesthetic used but rather the response of the patient to the anesthesia.
