Anaphylaxis in general anaesthesia occurs with a frequency of 1:5000-1:20000. This clinical summary reports on the use of an effective risk management strategy employing second line anaesthesia agents and alternative endotracheal intubation tools in a patient with a recent history of an intra-operative anaphylaxis to an unknown anaesthetic agent. A 71-year-old male presented for a repeat biopsy of corpus callosum 4 days following the cancellation of the procedure for a presumed anaphylactic reaction to an unknown anaesthetic agent. During the repeat care episode, the decision was made to proceed based on the urgent need for tissue diagnosis to facilitate further treatment and lack of feasibility for more definitive identification of the causative agent(s). A consideration was made of the optimum ways to manage and mitigate risk in this setting. The airway was managed using flexible endoscopic intubation in a spontaneously ventilating awake patient. Continuous remifentanil infusion was maintained throughout the case. Anaesthesia was maintained with sevoflurane at less than one MAC, with an uneventful completion of the biopsy of corpus callosum. All of the anaesthetic agents used during the prior care episode, with the exception of remifentanil, were avoided. In cases of an anaphylaxis to an unknown anaesthetic allergen, anaesthetic strategy consists of careful risk mitigation and deployment of second agent approaches. Awake flexible endoscopic intubation and remifentanil infusion are viable alternatives to standard induction techniques.
