To the Editor:—  Often stuck syringes are encountered and there are no special devices available to loosen them. Unless hopelessly stuck, they may easily be loosened with materials found in any physician's office. The smallest syringe at hand, a tuberculin or a 2 cc. syringe, is filled half full of water and a one-half inch hypodermic needle is attached. The needle is passed through a thickness of rubber, such as a rubber band, and then inserted firmly into the tip of the stuck syringe. Pressure is then made on the plunger of the syringe containing water, which in turn is transmitted to the stuck plunger, forcing it loose. The smaller the area of the end of the free plunger to that of the stuck plunger, the greater the hydraulic advantage obtained. Some care should be used in attempting to free badly stuck syringes by this method.601 State Office Building.
