The chief advantage of this anesthetic shield (Fig. 1) is that it is not attached to the table, and consequently it can be arranged for various operative positions. It consists of a plate of steel 20 inches long, 8 inches wide and one-eighth inch thick with an upright rod 7½ inches high at each end. The shield portion is composed of four bars, separated 3 inches at the highest point, which gradually converge and are inserted in the upright rods by a screw device which enables the adjustment of the shield at various levels to suit the thickness of the patient's chest. The plate is placed under the pillow or between the pillow and the pad covering the table.

Figure 2 shows the shield in position for the majority of operations.

Figure 3 shows the shield placed diagonally across the corner of the table for breast and shoulder operations.
