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 [...]
ACUTE CONFUSIONAL STATES AND DEMENTIA IN THE ELDERLY: THE ROLE OF DEHYDRATION/VOLUME DEPLETION, PHYSICAL ILLNESS AND AGE
A prospective study was undertaken to investigate the incidence and aetiology of acute confusional states in physically ill old people. The subjects were 71 patients aged 70 years or over who were admitted as emergencies to a general medical unit. Mental testing revealed that: (a) one in six patients had an acute confusional state on [...]
PROBLEM: THIRST, DRINKING BEHAVIOR, AND INVOLUNTARY DEHYDRATION
The phenomenon of involuntary dehydration, the delay in full restoration of a body water deficit by drinking, has been described extensively but relatively little is known about its physiological mechanism. It occurs primarily in humans when they are exposed to various stresses including exercise, environmental heat and cold, altitude, water immersion, dehydration, and perhaps microgravity, [...]
EFFECT OF DRINK FLAVOR AND NACL ON VOLUNTARY DRINKING AND HYDRATION IN BOYS EXERCISING IN THE HEAT
This study was intended to assess the influence of drink flavor and composition on voluntary drinking and hydration status in children exercising intermittently at 35 +/- 1 degrees C and 45-50% relative humidity. Twelve boys (9-12 yr) performed three 3-h identical sessions (four 20-min cycling bouts at 50% maximal O2 uptake followed by 25-min rest). [...]
