Urine colour as an index of hydration in critically ill patients

In order to test the hypothesis that urine colour can be used as an index of hydration in critically ill patients, we selected 40 intensive care and high-dependency patients and correlated urine colour (scored on an eight-point scale) with various indices of hydration: urine:plasma sodium, osmolality and urea ratios, urine output and central venous pressure. In addition, we compared the colour-chart score with scores made by intensive care nurses (without the benefit of a colour chart) in [...]

Effects of solution osmolality on absorption of select fluid replacement solutionsin human duodenojejunum.

These experiments examined relationships between initial osmolality and carbohydrate (CHO) composition of an infused solution and osmolality and water and CHO absorption in a test segment. A triple-lumen tube with a 10-cm mixing segment and a 40-cm test segment was passed into the duodenojejunum. The infusion port was approximately 10 cm beyond the pyloric sphincter. [...]

Metabolic and thermodynamic responses to dehydration-induced reductions in muscle blood flow in exercising humans

1. The present study examined whether reductions in muscle blood flow with exercise-induced dehydration would reduce substrate delivery and metabolite and heat removal to and from active skeletal muscles during prolonged exercise in the heat. A second aim was to examine the effects of dehydration on fuel utilisation across the exercising leg and identify factors related to fatigue. 2. Seven cyclists performed two [...]

THERMOREGULATORY RESPONSES AND HYDRATION PRACTICES IN HEAT-ACCLIMATIZED ADOLESCENTS DURING PRESEASON HIGH SCHOOL FOOTBALL

Previous researchers have not investigated the thermoregulatory responses to multiple consecutive days of American football in adolescents. OBJECTIVE: To examine the thermoregulatory and hydration responses of high school players during formal preseason football practices. DESIGN: Observational study. SETTING: Players practiced outdoors in late August once per day on days 1 through 5, twice per day [...]

PHYSICAL ACTIVITY, FOOD INTAKE, AND BODY WEIGHT REGULATION: INSIGHTS FROM DOUBLY LABELED WATER STUDIES

Body weight and energy balance can be maintained by adapting energy intake to changes in energy expenditure and vice versa, whereas short-term changes in energy expenditure are mainly caused by physical activity. This review investigates whether physical activity is affected by over- and undereating, whether intake is affected by an increase or a decrease in [...]

EXERCISE IN A HOT ENVIRONMENT: COMPARISON OF TWO DIFFERENT FLUID INTAKE PATTERNS

Aim. Extensive research has been undertaken in the area of exercise and hydration. Most work has focused on prehydration. Less is known about different fluid intake patterns during exercise and its effect in thermoregulatory variables in hot environments. This study attempted to determine if ingesting fluid either in a single bolus or intermittently during exercise [...]

HYDRATION, HYDRATION, HYDRATION

Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at-risk workers. Management of [...]

FUNCTIONAL SKIN ADAPTATION IN INFANCY – ALMOST COMPLETE BUT NOT FULLY COMPETENT

Early postnatal life is a period of active functional reorganization and cutaneous physiological adaptation to the extrauterine environment. Skin as the outermost organ of mammalians is endowed of multiple functions such as protection, secretion, absorption and thermoregulation. Birth stimulates the epidermal barrier maturation and the skin surface acidification especially in premature infants. In full-term infants [...]

INFLUENCE OF GENDER AND BODY COMPOSITION ON HYDRATION AND BODY WATER SPACES

BACKGROUND & AIMS: Hydration disorders are frequent in clinical practice and can be a life threatening issue in frail patients. Mild dehydration (1-2% loss of body weight) appears to impair cognitive and muscular performance. There is, however, no infallible indicator of correct hydration, and of hydration disorders. This study aim at describing total body water [...]
