Review[Allergic reactions and pseudoallergies in surgical interventions with general anesthesia].
The Spanish Societies of Allergology and Anesthesiology have established a protocol for action for the performance of allergy tests for anesthesia. The protocol was published by the General Directorate of INSALUD, along with an informed consent form for general and loco-regional anesthesia, on 30 June 1994. Despite this, demands for care and requests for allergologic and anesthetic studies have increased. ⋯ Prevention should begin with the selection of less potent drugs, such as histamine releasing agents. Slow administration of drugs, as opposed to bolus administration, has been demonstrated to be more effective. The use of combined H1 and H2 antihistamines as a preanesthetic medication can significantly reduce tachycardia/bradycardia, hypotension, skin response, and even gastric pH changes induced by histamine release.
