Clear-fluid diet
This is an allowance of tea, coffee or coffee substitute, and fat-free broth. Ginger ale, fruit juices, flavored gelatin, fruit ices, and water gruels are sometimes given. Small amounts of fluid are offered every hour or two to the patient.
The diet is used for 24 to 48 hours following acute vomiting, diarrhea, or surgery.
The primary purpose of this diet is to relieve thirst and to help maintain water balance. Broth provides some sodium, and fruit juices contribute potassium. Carbonated beverages, sugar, and fruit juices, when used, furnish a small amount of carbohydrate.
Full-fluid diet
This diet consists of liquids and foods that liquefy at body temperature. It is used for acute infections of short duration and for patients who are too ill to chew. It may be ordered as the first progression from the clear-fluid diet following surgery or in the treatment of acute gastrointestinal upsets.
The diet is offered in six feedings or more. Initially, amounts smaller than those represented by the plan below are given. To increase the caloric intake, 1 pt light cream may be substituted for 1 pt milk. The protein level of the full-fluid diet may be increased by adding nonfat dry milk to fresh milk, cream soups, cereal gruels, or custards. Strained meats may be added to broth or to hot tomato juice.
