The method for inducing continuous spinal anesthesia introduced by Lemmon1 in 1940 has transferred the procedure for obtaining subarachnoid block to the category of controllable methods. This has greatly increased its adaptability and safety. Recently we2 described a continuous drop method for maintaining subarachnoid analgesia.

TECHNIC  In addition to the special mattress, malleable needle, tubing and stopcock of Lemmon, the equipment includes a 250 cc. leveling flask and tubing fitted with a Murphy dropper, a regulating valve and a glass adapter (fig.). After the lumbar puncture is accomplished and the patient turned to the recumbent position, the initial dose of anesthetic solution is given, as would be done with the fractional method of administration. For this dose we use 2.5 per cent procaine hydrochloride in a 2.5 per cent solution of dextrose in isotonic solution of sodium chloride. The size of the initial dose depends on the height
