The original purpose of muscle relaxants in anaesthesia was to relax abdominal muscles during surgery without the need to saturate patients with ether. With the passage of time, the indications have expanded to include the provision of relaxation for various examinations under anaesthetic, to facilitate passage of endotracheal tubes, to allow the conduct of artificial respiration, and—by suppressing reflex movements to painful stimuli when small doses are given—to reduce the total quantity of anaesthetic needed for any particular operation.
