Fig. 112.—Method of dilating rectum with hand in cone shape. By drawing out the skin of this region with one hand the tissuesare put upon the stretch, and all folds and creases obhterated (), making it less likely to transfix a fold causing pain; the solutionis injected as the needle is advanced; for each re-insertion of the 4i6 LOCAL ANESTHESIA needle

(From Braun.) Anesthesia results almost immediately, at most after a delay of afew minutes, when dilatation may be begun and can be as thoroughlycarried out as under a general anesthetic. A graphic illustration of the method of making these injectionsis shown in Fig. in. The author always prefers to use the hand asa dilating medium, which is less likely to tear or lacerate the parts,using soap as the lubricating medium; first one finger is passed, thentwo and three, and, finally, the whole hand in a cone-shape is rotatedaround in a screw-like fashion (Fig. 112) until dilatation is is the method always used by Prof. Matas for dilatation and issuperior to any other.
