EFFECT OF SALT AND WATER BALANCE ON RECOVERY OF GASTROINTESTINAL FUNCTION AFTER ELECTIVE COLONIC RESECTION: A RANDOMISED CONTROLLED TRIAL
BackgroundnnLow concentrations of albumin in serum and long gastric emptying times have been returned to normal in dogs by salt and water restriction, or a high protein intake. We aimed to determine the effect of salt and water balance on recovery of gastrointestinal function after elective colonic resection in human beings.nMethodsnnWe randomly allocated ten patients [...]
INHALED MANNITOL IMPROVES THE HYDRATION AND SURFACE PROPERTIES OF SPUTUM IN PATIENTS WITH CYSTIC FIBROSIS
The airway mucus in patients with cystic fibrosis (CF) is dehydrated and adhesive and accumulates in the airways, resulting in chronic inflammation, infection, and progressive loss of lung function. Inhaled mannitol improves mucus clearance and, when administered over 2 weeks, it improves lung function in CF (Jaques et al. Chest. 2008;133(6):1388-1396). The changes in the [...]
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 [...]
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 [...]
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 [...]
HOW TO ENSURE PATIENT OBSERVATIONS LEAD TO EFFECTIVE MANAGEMENT OF OLIGURIA
Fluid balance is essential for normal functioning of the body. Oliguria (poor urine output) is usually associated with low circulatory blood volume (hypovolaemia), and can be a sign that a patient is acutely ill and deteriorating.
THREE PERCENT HYPOHYDRATION DOES NOT AFFECT THE THRESHOLD FREQUENCY OF ELECTRICALLY-INDUCED CRAMPS
PURPOSE:: Dehydration is hypothesized to cause exercise-associated muscle cramps (EAMC). The theory states that dehydration contracts the interstitial space thereby increasing the pressure on nerve terminals and cramps ensue. Research supporting this theory is often observational and fatigue is rarely controlled. Inducing cramps with electrical stimulation minimizes many of the confounding factors associated with exercise-induced [...]
HEART RATE RESPONSES AND FLUID BALANCE OF COMPETITIVE CROSS-COUNTRY HANG GLIDING PILOTS
PURPOSE: To evaluate the physiological challenges of competitive cross-country hang gliding. METHODS: Seventeen experienced male pilots (age=41+/-9 y; mean+/-SD) were fitted with a monitor that recorded heart rate and altitude at 0.5 Hz throughout a competitive flight. Fluid losses were evaluated by comparing pilot pre- and postflight mass. RESULTS: The pilots' displacement was 88.4+/-43.7 km [...]
THE ROLE OF HYDRATION IN VOCAL FOLD PHYSIOLOGY
PURPOSE OF REVIEW: Increased vocal fold hydration is a popular target in the prevention and management of voice disorders. Current intervention strategies focus on enhancing both systemic (internal) and superficial (surface) hydration. We review relevant bench and human research on the role of hydration in vocal fold physiology. RECENT FINDINGS: Bench and human studies provide [...]
