BACKGROUND & AIMS: Previous studies have suggested that oral or intravenous glucose enhances salt and water retention following a saline load. To test this, we studied the effects of an oral glucose load on urinary sodium and water excretion and serum biochemistry in response to a 2l intravenous infusion of 0.9% saline in normal subjects. [...]
AIMS AND OBJECTIVES: The aim of this prospective study was to examine whether preoperative face-to-face counselling about a child's fasting and active preoperative nutrition have an effect on thirst, hunger and postoperative oral intake in paediatric ambulatory tonsillectomy. Families, whose child was admitted for ambulatory tonsillectomy, participated in the study (n = 116; 58/58). BACKGROUND: [...]
Background & aimsnNasogastric feeding may result in gastro-oesophageal reflux and, therefore, increase the risk of aspiration. This may be greater when feeds are administered via a bolus than by infusion. We aimed to measure gastric emptying time and quantify gastro-oesophageal reflux in healthy volunteers given a liquid feed via an oral bolus (OB), a nasogastric [...]
The purpose of this study was to examine the effects of fluid ingestion on pacing strategies and performance during intermittent-sprint exercise in the heat. Nine male rugby players performed a habituation session and 2 50-min intermittent-sprint protocols at a temperature of 31°C, either with or without fluid. Participants were informed of a third session (not [...]
OBJECTIVES: To investigate the drinking behavior of the participants in a multi-day mountain bike (MTB) cross-country competition, to monitor its effect on the body's fluid compartments and body mass, and to evaluate the prevalence of exercise-associated dysnatremia. DESIGN: Descriptive field study. SETTING: The Jeantex Bike Transalp Competition 2008 (8 stages; 665.40 km; 21 691 m [...]
BACKGROUND: The study investigators conducted a vigorous screening protocol for delirium in rural long-term care (LTC) facilities for a period of 28 days focusing on Bioelectrical Impedance Analysis (BIA) and other hydration parameters as risk factors. METHODS: A two-stage cluster sampling procedure was used to randomly select participants (n = 313) from 13 LTC facilities [...]
Hyponatraemia is a commonly encountered electrolyte abnormality in hospitalised patients and is associated with significant morbidity and mortality. The fact that most cases of hyponatraemia are the result of water imbalance rather than sodium imbalance underscores the role of antidiuretic hormone (ADH) in the pathophysiology. Hyponatraemia can be classified according to the measured plasma osmolality [...]
INTRODUCTION: Water intoxication is a rare cause of coma. The leading causes of excessive hydration are endurance exercise, drug abuse, iatrogenic, cerebral salt wasting, or psychiatric conditions. Self-induced water intoxication in an otherwise healthy person is exceedingly rare. METHODS: Single patient case report and review of the literature. RESULTS: We describe a previously fit and [...]
The case histories are presented of four athletes taking part in a 95-mile ultra-endurance foot race in Scotland who were hospitalised after developing exercise-associated hyponatraemia and rhabdomyolysis. Exercise-associated hyponatraemia is relatively uncommon in temperate climates. Risk factors disposing to this disorder are discussed. Exercise-associated hyponatraemia is thought to be due to overconsumption of hypotonic fluid [...]
The use of oral rehydration solution (ORS) has revolutionized the management of acute diarrhea. The implementation of the standard World Health Organization ORS (WHO-ORS) has resulted in decreased mortality associated with acute diarrheal illnesses in children, although in general stool volume and diarrhea durations are not reduced. Decreased morbidity and mortality have occurred because of [...]
