DISTRIBUTION OF WATER LOSSES AMONG FLUID COMPARTMENTS OF TISSUES UNDER THERMAL DEHYDRATION IN THE RAT

Dehydration amounting to about 10% of body weight was induced in adult male rats by exposure to a hot, dry environment (D.B.T., 36 degrees C; R.H., 20%) over 6 to 8 hr. The volumes of total water (TW), extracellular fluid (ECF), and plasma (PV) were determined both on individual tissues and on the whole body [...]

INGESTION OF COLD FLUIDS: RELATED TO ONSET OF ARRHYTHMIAS?

Although the results of this study provide too limited a database for establishing definitive guidelines for practice, they underscore the need for critical care nurses to focus observations on patients' responses to iced fluid restriction. It is important to determine whether and to what extent limiting ingestion of iced fluids induces patient stress, a factor [...]

EFFECT OF SALT INTAKE ON RENAL EXCRETION OF WATER IN HUMANS

Two studies were performed to determine the quantitative relationship between salt intake and urinary volume (U(v)) in humans. In study 1, 104 untreated hypertensives were studied on the fifth day of a high- and a low-salt diet. The 24-hour U(v) was 2.2 L (urinary sodium [U(Na)] 277 mmol) on the high-salt diet and decreased to [...]

EFFECTS OF FLUID, ELECTROLYTE AND SUBSTRATE INGESTION ON ENDURANCE CAPACITY

The availability of carbohydrate (CHO) as a substrate for the exercising muscles is known to be a limiting factor in the performance of prolonged cycle exercise, and provision of exogenous CHO in the form of glucose can increase endurance capacity. The present study examined the effects of ingestion of fluids and of CHO in different [...]
