It is recommended that you have the following emergency drugs drawn up, labelled and ready to use before any case:
Suxamethonium (100mg in 2 ml)
Atropine (1mg in 1 ml)
In addition to this many anaesthetists also prepare vasopressor agents for use in hypotension which may be associated with induction or spinal/epidural anaesthesia:
Ephedrine (30 mg in 10 mls of saline)
Metaraminol (10 mg in 20 mls of saline)
