Planocaine in Spinal Anæsthesia

Siij,?May I point out, to any who feel reluctant to use percaine on account of the waste of time entailed in keeping the patient in the prone position for ten minutes after injection, that the prone position is now considered unnecessary. I now give percaine, the usual hypoboric solution, with the patient sitting up. Depending upon the height of anaesthesia required, the patient is allowed to sit up from twenty to forty seconds after the commencement of the injection. He can then be placed in the dorsal position, with the table tilted downward by the head through an angle of 15?, the tilt being reduced by 5? after five minutes.
