~Total Abstinence.~--No food is given for twenty-four hours following the operation (1) on account of the nausea and vomiting which so often follows the giving of an anesthetic--ether particularly--and (2) because the entire organism is better for a complete rest. ~Routine Treatment.~--The routine treatment in uncomplicated cases is rest, then water, very hot or iced, or carbonated, or vichy in spoonful doses, then albumen water, broth, etc., then milk, buttermilk, koumiss, etc., after which the semi-solids, etc., until a normal diet is reached. After a week or more the character of the operation certainly determines the dietetic treatment. To quote Dr. Thomas S. Brown,[106] "To give the same diet after pyloroplasty, gastro-enterostomy, gall bladder operation, or gastric resection as we would after operations for fracture of the thigh or cancer of the breast shows a basic ignorance of the pathologic physiology of the former group of cases." "We should remember that hyperacidity remains long after the underlying cause has been removed and it is tempting providence, to say the least, to ply these patients with tomato soup, salad dressing, and coarse food in the early stages of their convalescence." ~Character of Diet.~--It must be kept in mind that the character of the diet is of vital importance, especially in the after-treatment of operations upon the stomach. In gastro-enterostomy, for example, the food mass passes from the stomach directly into the upper part of the small intestine through the new opening. Thus the semi-liquid food highly acid in character comes in direct contact with the delicate intestinal walls which are accustomed, not to the acid, but to a neutral or alkaline medium. ~Adjusting Diet to Disease.~--Thus it is demonstrated that unless care is used in selecting the diet this portion of the intestinal tract will be injured; hence the nurse must understand which foods are liable to stimulate an excess flow of acid in the stomach and avoid them. She must also keep in mind that the foods given must be in a semi-liquid or very finely divided condition, since the mechanical efforts made by the musculature of the gastric organ act as a direct stimulant to the secretory cells of that organ. * * * * * Much of the responsibility thus rests upon the nurse whose business it is to administer the diet. The efforts of the best surgeon in the world may be entirely overcome by a careless, thoughtless, or ignorant nurse.
