A rare cause of oxygen failure

At the recent Winter Scientific Meeting of the Association, the lecture by Professor Nimmo regarding anaphylactic reactions during anaesthesia provoked the following question regarding pre-operative assessment. Would it not be better to look for safe anaesthetic agents, rather than test for agents to which the patient is likely to react? A patient with a previous anaphylactic reaction during anaesthesia or other drug administration or with a marked history of allergy could be assessed for a number of drugs that could be safely used during anaesthesia. One might test for etomidate, fentanyl and vecuronium by patch testing, and thus identify agents with which one could safely anaesthetise the patient. Adopting this procedure would indicate which drugs were safe rather than those that were dangerous, thus reducing the risk during the anaesthetic.
