The ethyl chloride and rectal ether technique.

This film shows the induction and maintenance of anaesthesia by ethyl cloride and rectal ether.A middle-aged male patient is roused from his semi-conscious state, an attendant is shown holding an alarm clock indicating with its second hand how quickly this occurs. A blackboard with chalked up details of the patient is shown. This indicates that the patient is 'tough' (to anaethetise). A second patient is shown profoundly anaesthetised; his eyelids are drawn back. He is roused. The equipment is shown functioning in detail.
