Anaesthetic pre-assessment
It is important to be aware that patients who are susceptible to MH may not develop the condition every time they have a general anaesthetic, even when that anaesthetic includes the triggering drugs. A history of uneventful previous anaesthetics therefore does not exclude the possibility of MH in future anaesthetics. This is why every patient attending the anaesthetic preassessment clinic should be asked about a family history of anaesthetic problems.
