Dehydration in the elderly: a short review.

DehydrationÂ is the most common fluid and electrolyte problem among theÂ elderly. The usual causes of water loss are frequently absent in dehydratedÂ elderlyÂ patients. Age-related changes in total body water, thirst perception, renal concentrating ability, and vasopressin effectiveness probably predispose toÂ dehydration.Â DehydrationÂ related to infection, high-protein tube feedings, cerebral vascular accidents, and medication-related hypodypsia are particularly relevant forÂ elderlypatients. Appropriate treatment [...]

Fluid and electrolyte balance in ultra-endurance sport.

It is well known that fluid and electrolyte balance are critical to optimal exercise performance and, moreover, health maintenance. Most research conducted on extreme sporting endeavour (>3 hours) is based on case studies and studies involving small numbers of individuals. Ultra-endurance sportsmen and women typically do not meet their fluid needs during exercise. However, successful [...]

Dehydration: biological considerations, age-related changes and risk factors in older adults

Maintenance of water balance is essential to normal physiologic function and vigorous aging.Â OlderÂ adults, however, frequently experience alterations in fluid homeostasis, which result inÂ dehydration. This article describes the physiology of water balance,Â age-relatedÂ changesÂ that influence fluid regulation, and associatedÂ riskÂ factorsÂ forÂ dehydrationÂ inÂ olderÂ adults. Fluid hygiene is an important health promotion activity for this age group, but when efforts to prevent imbalance are [...]

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. [...]

Human hydration indices: acute and longitudinal reference values.

It is difficult to describe hydration status and hydration extremes because fluid intakes and excretion patterns of free-living individuals are poorly documented and regulation of human water balance is complex and dynamic. This investigation provided reference values for euhydration (i.e., body mass, daily fluid intake, serum osmolality; M +/- SD); it also compared urinary indices [...]

Volume repletion after exercise-induced volume depletion in humans: replacement of water and sodium losses.

Sodium and water loss during, and replacement after, exercise-induced volume depletion was investigated in six volunteers volume depleted by 1.89 +/- 0.17% (SD) of body mass by intermittent exercise in a warm, humid environment. Subjects exercised in a large, open plastic bag, allowing collection of all sweat secreted during exercise. For over 60 min beginning [...]

Sodium loading aids fluid balance and reduces physiological strain of trained men exercising in the heat.

PURPOSE: This study was conducted to determine whether preexercise ingestion of a highly concentrated sodium beverage would increase plasma volume (PV) and reduce the physiological strain of moderately trained males running in the heat. METHODS: Eight endurance-trained (.VO2max: 58 mL.kg(-1).min(-1) (SD 5); 36 yr (SD 11)) runners completed this double-blind, crossover experiment. Runners ingested a [...]

Urinalysis: a comprehensive review.

A complete urinalysis includes physical, chemical, and microscopic examinations. Midstream clean collection is acceptable in most situations, but the specimen should be examined within two hours of collection. Cloudy urine often is a result of precipitated phosphate crystals in alkaline urine, but pyuria also can be the cause. A strong odor may be the result [...]

Swallowing, nutrition, and hydration during acute stroke care.

Dysphagia occurs in up to half of patients after anÂ acute strokeÂ and may cause dehydration, undernutrition, and aspiration pneumonia. Current evidence suggests that a systematic program of diagnosis and treatment of dysphagia in anÂ acute strokeÂ management plan may yield dramatic reductions in aspiration pneumonia rates. There is also some evidence thatnutritionalÂ supplementation and properÂ hydrationÂ may reduce morbidity and mortality [...]
