An average of 10 syringes are used per anaesthetic; the saving in operating theatre time (costed at £20 per minute) from not having to draw syringes up at the start is particularly beneficial. Prefilled syringes can be instantly available; a recent report concerned a patient who became hypotensive and died during transfer to the ICU when a noradrenaline infusion syringe ran out. Prefilled Syringes of noradrenaline 4/8/16/32 mg in 50 ml are commercially available.
