STOMACH TUBE ADMINISTRATION
—In certain diseases and emergencies, feeding and drug administration by stomach or duodenal tube may become necessary. When, for instance, the patient is unconscious, or for one reason or another unwilling or unable to swallow, food as well as medicine may be placed in the stomach by means of a tube, a procedure known as gavage. Under these circumstances, it is usually easier to pass the tube through the nose than through the mouth. It is less apt to enter the trachea, and the mouth does not have to be pried and kept open by instruments. A tube the diameter of a no. 20 French catheter is employed. For infants, a no. 10 catheter suffices. For adults, the tube should be more than 45 cm. long, as, for example, a duodenal tube; and, if difficulty is encountered in its passage, it may be stiffened
