THE CONTROL OF STRYCHNINE CONVULSIONS BY INTRASPINAL INJECTIONS OF MAGNESIUM SULPHATE.

We feel that the results obtained in the human case and in our animal experiments justify the supposition that magnesium sulphate may be of use in controlling cases of poisoning by strychnine. It is a method easily available not only in large hospitals but in private practice, and requires no elaborate technique. The amount of magnesium sulphate to be used should follow the advice of Meltzer (19) in tetanus cases: intraspinally 1 cc. of a 25 per cent solution to each 20 pounds of body weight in adults, and one-half the dose in young children. Should this not control the convulsions a small amount of ether may be used. In order to hasten the excretion of strychnine, 200 to 300 cc. of salt solution should be given intravenously.(6) In the event of the return of the convulsions, the intraspinal dose may be repeated, always taking precautions to keep the head elevated. Meltzer's apparatus for intrapharyngeal insufflation and a 2.5 per cent solution of calcium chloride should always be on hand in case of respiratory failure following an overdose of the magnesium salts (Meltzer (19)).
