Body water balance in hemodialysis patients reflects nutritional, circulatory, and body fluid status
In 219 recreational male runners, we investigated changes in body mass, total body water, haematocrit, plasma sodium concentration ([Na(+)]), and urine specific gravity as well as fluid intake during a 100-km ultra-marathon. The athletes lost 1.9 kg (s = 1.4) of body mass, equal to 2.5% (s = 1.8) of body mass (P < 0.001), 0.7 kg (s = 1.0) of predicted skeletal muscle mass (P < 0.001), 0.2 kg (s...
Chuckwalla lizards (genus Sauromalus) may accumulate substantial quantities of body fluid in extracoelomic, lateral abdominal spaces called accessory lymph sacs. The lymph sac fluid (LSF) of S. hispidus is similar to that of serum in Na+, K+ and Cl- concentrations, but the total protein content (3.58 +/- 0.20 g dl-1) is only half that measured in serum (7.05 +/- 0.26 g dl-1). These analyses con...
OBJECTIVE To present a practical approach to the management of osmolar disorders by considering the mechanisms involved in their development. DATA SOURCES Articles and published peer-review abstracts on the mechanisms and management of disorders of plasma osmolality. SUMMARY OF REVIEW In health, plasma osmolality is determined largely by the concentration of sodium and its accompanying anio...
for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day -1 . Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h -1 , and fluid loss at this rate si...
Nurses must know about effect and indication ofl.V-Fluid Therapy. Priciples of WMuid therapy consist of:Appropriate solutions and the rate of administration of fluid, types of parenteral solutions and the factors that indicate whether a solution is appropriate or not, definition of smolarity andm smolality and how to use the standard formula. Knowing a pateint's body fluid concentration , or fl...
