FLUID AND ELECTROLYTE BALANCE: THE IMPACT OF GOAL DIRECTED TEACHING
Background & aimsnWe aimed to determine if a structured workshop on fluid and electrolyte balance for junior surgical trainees led to an improvement in knowledge on the subject and to evaluate the perceived helpfulness of such a workshop.nnMethodsnSurgical trainees attended an interactive lecture-based workshop on fluid and electrolyte balance. Participants had online access to the [...]
REDUCED THIRST AFTER WATER DEPRIVATION IN HEALTHY ELDERLY MEN
To determine whether responses to dehydration are altered with age, we investigated the thirst, fluid and electrolyte responses, and hormonal responses to 24 hours of water deprivation in seven healthy active elderly men (67 to 75 years old) and seven healthy young men (20 to 31 years old) who were matched for weight loss during [...]
FLUID CONSUMPTION AND SWEATING IN NATIONAL FOOTBALL LEAGUE AND COLLEGIATE FOOTBALL PLAYERS WITH DIFFERENT ACCESS TO FLUIDS DURING PRACTICE
CONTEXT: Considerable controversy regarding fluid replacement during exercise currently exists. OBJECTIVE: To compare fluid turnover between National Football League (NFL) players who have constant fluid access and collegiate football players who replace fluids during water breaks in practices. DESIGN: Observational study. SETTING: Respective preseason training camps of 1 National Collegiate Athletic Association Division II (DII) [...]

THE HISTORY OF 0.9% SALINE
BACKGROUND & AIMS: We aimed to trace the historical origins of 0.9% saline, how it came to be used so commonly today, and to consider whether its continued use can be justified. METHODS: We searched the Medline, Science Citation Index, ScienceDirect and Google databases using the key words saline, physiological, salt solution, sodium chloride, 0.9%, [...]
THIRST AND FLUID REGULATORY RESPONSES TO HYPERTONICITY IN OLDER ADULTS
To assess the fluid regulatory responses in aging adults, we measured thirst perception and osmoregulation during and after infusion of hypertonic NaCl) saline in older (72 +/- 2 yr, n = 6) and younger (26 +/- n = 6) subjects. Hypertonic saline was infused at 0.1 min-1.kg-1 for 120 min. On a separate day, the [...]
THE TREATMENT OF HYPONATREMIA
Virtually all investigators now agree that self-induced water intoxication, symptomatic hospital-acquired hyponatremia, and hyponatremia associated with intracranial pathology are true emergencies that demand prompt and definitive intervention with hypertonic saline. A 4- to 6-mmol/L increase in serum sodium concentration is adequate in the most seriously ill patients and this is best achieved with bolus infusions [...]
MECHANISM OF ATTENUATED THIRST IN AGING: ROLE OF CENTRAL VOLUME RECEPTORS
To test the hypothesis that the inhibitory action of central blood volume expansion on thirst and renal fluid regulation is attenuated with aging, we monitored the drinking and renal responses of dehydrated older (70 +/- 2 yr, n = 6) and younger (24 +/- 1 yr, n = 6) subjects during 195 min of head-out [...]
THIRST AND HYDRATION: PHYSIOLOGY AND CONSEQUENCES OF DYSFUNCTION
The constant supply of oxygen and nutriments to cells (especially neurons) is the role of the cardiovascular system. The constant supply of water (and sodium) for cardiovascular function is the role of thirst and sodium appetite and kidney function. This physiological regulation ensures that plasma volume and osmolality are maintained within set limits by initiating [...]
