Anaphylactic Bronchospasm during Induction of General Anaesthesia: A Case Report

Bronchospasm represents the clinical manifestation of bronchial muscles contraction resulting in reduced alveolar air flow. Non-allergic mechanisms or anaphylaxis underlie the genesis of perioperative bronchospasm, a potential anaesthetic disaster. Early recognition and treatment are crucial. We report a rare incident of anaphylactic bronchospasm without hypotension during general anaesthesia. Urticaria appeared in chest and abdomen suggesting anaphylaxis. After the event resolved with bronchodilators, surgery continued uneventfully. Vecuronium was the most probable culprit but confirmation was not possible as the patient was lost to follow up. Rarely, perioperative anaphylaxis presents only with bronchospasm that requires prompt attention to avoid adverse outcome. Keywords: allergy; anaphylaxis; bronchial spasm; general anesthesia.
