No anaesthetic is without risk but most patients do not suffer anaesthetic complications. When they do occur, complications vary from the mild and inconvenient (headache, nausea, sore throat, hoarse voice, drip site bruising) to the severe but very rare, such as major allergic reactions.
One of the purposes of the pre-anaesthetic consultation is to provide an opportunity for the discussion of risks and complications. This is an ideal time for you to ask any questions about your anaesthetic. This opportunity may not arise before emergency procedures.
