The patients hand is held by 328 REGIONAL ANESTHESIA the operator in such a way that one of his fingers may control theposition of the point of the needle at any time during the procedureand thus prevent it from piercing the skin of the palmar region. NeedleNo. 2 (5 cm.), attached to the syringe filled with the 1 per cent, solu-tion, is passed through wheals 5 and 6 in succession and the solutiondistributed fanwise in the interosseous space, against the metacarpalbone. The needle is then inserted through 5 and 7 and advanced towardA in the palm of the hand, and the solution distributed subcutaneously
