Dehydration and venous thromboembolism thromboembolism after acute stroke.

BACKGROUND:Although it is widely assumed that dehydration predisposes to venous thromboembolism (VTE), there are no clinical studies to support this. Aim: To evaluate the relationship between biochemical indices of dehydration and VTEafter acute ischaemic stroke (AIS). DESIGN: Prospective observational study. METHODS: Unselected AIS patients (n = 102) receiving standard thromboprophylaxis with aspirin and graded compression stockings, underwent serial measurements of serum urea, creatinine and osmolality, and [...]

WATER, HYDRATION, AND HEALTH

This review examines the current knowledge of water intake as it pertains to human health, including overall patterns of intake and some factors linked with intake, the complex mechanisms behind water homeostasis, and the effects of variation in water intake on health and energy intake, weight, and human performance and functioning. Water represents a critical [...]

Dehydration in hospital-admitted stroke patients: detection, frequency, and association.

BACKGROUND AND PURPOSE: We aimed to determine the frequency of dehydration, risk factors, and associations with outcomes at hospital discharge after stroke.METHODS:nWe linked clinical data from stroke patients in 2 prospective hospital registers with routine blood urea and creatinine results. Dehydration was defined by a blood urea-to-creatinine ratio >80. RESULTS:nOf 2591 patients registered, 1606 (62%) [...]

Water: a neglected nutrient in the young child? A South African perspective

Water is considered an essential nutrient because the body cannot produce enough water itself, by metabolism of food, to fulfil its need. When the quantity or quality of water is inadequate, health problems result, most notably dehydration and diarrhoea. As a result of contaminated water and poor hygiene, related infections are still a serious problem. Indeed, in theSouth African setting water availability and sanitation are critical issues because [...]

Fluid balance in elderly patients following stroke.

We studied the relationship between plasma osmolality, arginine vasopressin (AVP), and fluid input in patients during the acute phase of a first stroke. Fifteen consecutive patients were studied (median age 79) and their blood sampled on days 0, 1, 2, 3, 7 and 14. Plasma osmolality was related to fluid input over days 0-3 (p = 0.0013) and AVP over 14 days (p less [...]

Diarrhoea in the critically ill

PURPOSE OF REVIEW: The purpose of this review is to update the knowledge on diarrhoea, a common problem in critically ill patients. Epidemiological data will be discussed, with special emphasis on diarrhoea in tube-fed patients and during antibiotic therapy. The possible preventive and therapeutic measures will be presented. RECENT FINDINGS: The need for concise definitions of diarrhoea was recently re-emphasized. The use [...]

Comparison of 3 methods to assess urine specific gravity in collegiate wrestlers.

OBJECTIVE: To investigate the reliability and validity of refractometry, hydrometry, and reagent strips in assessing  urine specific gravity in collegiate wrestlers. DESIGN AND SETTING: We assessed the reliability of refractometry, hydrometry, and reagent strips between 2 trials and among 4 testers. The validity of hydrometry and reagent strips was assessed by comparison with refractometry, the [...]

Comparison between normal saline and a polyelectrolyte solution for fluid resuscitation in severely dehydrated infants with acute diarrhoea

The optimal intravenous solution for rehydration of infants and children with severe dehydration is debated. AIM: The aim was to compare the efficacy of a polyelectrolyte solution (group PS) with sodium chloride 0.9% solution (group NS) in rapid parenteral rehydration of severely dehydrated infants with acute diarrhoea. METHODS: Primary outcomes were volume and time to hydration. Secondary outcomes were urea, creatinine, electrolytes, glucose, arterial pH and bicarbonate levels. Patients were [...]

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 [...]
