In the last hospital I worked in , in Australia, first line drug for fitters was midazolam. It seemed the ideal drug, very fast working, so you can titrate it to effect with less timelag /overkill. Another advantage is that it wears off more quickly so that a patient can be assessed alert with less of that diazemuls/lorazepam twilight zone, where you are wondering whether this is post-ictal, effect, benzos or head injury. I have not found overdosage and consequent respiratory problems to be an issue. Paul Ransom
