The anaesthesia ofthe part continues until the proximal bandage is reestablishment of the circulation is rapidly followedby a return of the sensation. 254 ANESTHESIA The method may prove serviceable for emergency am-putations in situations where a general anaesthetic is forone or more reasons contraindicated. The method appears more thorough and reliable thanthat offered by surface anaesthesia, for the solution injectedinto the vein reaches and anaesthetizes the deepest struc-tures at a single injection. This method has been used more than 500 times bydifferent operators who report success in about 90 per cent,of their cases.
