CHAPTER X.. Directions for Locating and Injecting the Brachial Artery.

Directions for Locating and Injecting the Brachial Artery.

The course of the Brachial Artery is in a line drawn from the outer side of the armpit to the center of the bend of the elbow, and along the inner edge of the Biceps or largest muscle of the upper part of the arm (see illustration). This artery will be found just at the inner edge of the Biceps, at a point midway between the elbow and shoulder—sometimes a little under the edge of the muscle in very muscular subjects. Hold the arm out from the side of the body, twisting it a little outwards, and make the incision at the edge of the muscle. By reference to the plate illustrating the location of this artery, you will see the point marked for the incision. Having taken up the artery, make the slit and secure the syringe in it, the point directed towards the shoulder, and proceed according to the general directions already given for the Carotid Artery injection.
