The operating room and the patient; a manual of pre- and post-operative treatment . cting tube is used with asecond tube leading back to the can thisrestriction is not essential, as the returntube ensures accurate regulation of thequantity of fluid administered, regularity offlow, and prevents overdistention of thebowel. By using a Y-shap:d tube the resultis practically a slow Kemps irrigation of thelarge intestine with the absorption of all ofthe fluid. In case a Y-shaped tube is notused it is essential that a large inflow tubebe used and that the rectal tip have numer-ous openings to provide for the suddenreturn of the flow into the can when thepatient strains, wishes to expel fluid or voidgas. Any attempt to constrict the tube and thus control the flowwill result in the expulsion of the fluid alongside the tube and theconsecpent soiling of the bed. The lowest level and the shortestinflow tube give the best results. A saline drop regulator ofwhich several have been devised and of which that devised byE. C. RyalP (Fig. 148) is a type, is useful though not Fig. 148.—Dropregulator for use inproctoclysis. 1 Lancet, Xov. 18, 1911. GENERAL CONSIDERATIONS IN THE AFTER-TREATMENT 209 The barrel is made of toughened annealed glass and nickel-plated metal mounts at either end for attaching the tubesecurely cemented with metallic solder so that the appartuscan be sterilized. The stopcock allows of the regulationof the number of drops; three drops per second, is the rateadvised by Murphy. Instruments of this kind also allowof a short length of tubing between the saline receptacleand the rectum as the rate of flow can be controlled by theapparatus and the receptacle need not be raised or lowered. Itis necessary that the nurse note the rate of flow such an apparatus is used, however, it is best to use it inconjunction with the Y-shaped return tube already mentioned.
