Filter by:For more than 15 years, traditional fasting regimens prior to scheduled surgeries have been called into question, yet prolonged preoperative fasting remains common practice. While prolonged fasting is aimed at reducing the risk of pulmonary aspiration, prolonged fasting is uncomfortable, has an inconsistent effect on gastric volumes and acidity and may lead to dehydration without a clear reduction in the incidence of aspiration. Fasting by itself decreases hepatic glycogen stores, induces a state of insulin resistance and impairs cardiovascular function. Yet, prolonged preoperative fasting remains common. Preoperative oral carbohydrate (CHO) consumption improves insulin sensitivity and decreases the time to return of gut function without increasing gastric volumes or acidity compared to other clear liquids and fasting. Previous work has shown oral CHO consumption improves patient well-being to a greater degree than placebo drink (water or flavored water) and fasted controls. Oral CHO also outperforms a similar volume of intravenous glucose supplementation. These benefits have reduced hospital stays in a variety of surgical models by as much as 20%. Further, preoperative CHO supplementation improved postoperative patient hunger, thirst, anxiety, fatigue and nausea. The purpose of this research study is to determine if drinking a high carbohydrate beverage before cesarean section surgery can improve patient well-being, compared to patients who drink a low carbohydrate beverage or fast before surgery.
The study will explore in vivo lens dehydration rates across a 12hr wear period for the study lenses.

One of the leading health issues among patients, particularly children, presenting for care in low- and middle-income countries is dehydration. When oral rehydration is not sufficient or is clinically inappropriate, rehydration often occurs intravenously. An alternative to intravenous rehydration is subcutaneous infusion and - with or without hyaluronidase enzyme (or Hylenex) - has been shown in several robust trials in high-income countries to be as effective and even safer than intravenous infusion. In this study in western Kenya, the investigators propose a first-ever randomized controlled trial to evaluate whether hyaluronidase-facilitated subcutaneous infusion can be as effective and safe as IV therapy among moderate-to-severely dehydrated patients in low- and middle-income countries.
Acute gastroenteritis is a common cause of hospital admission and health office visits and have a huge burden on the economy of developing countries. The investigators proposed this observational prospective study during summer period in a community and tertiary care hospital in a rural area of Lebanon to investigate the etiologies and age distribution of admitted cases to general pediatric floor from the age of 1 month up to the age of 14 years.
The main purpose of this study is to assess and compare the hydration status of medical and nursing staff and to investigate the relationship between the hydration status, cognitive function and serum cortisol (marker of stress). We hypothesise that a significant proportion of doctors and nurses will be dehydrated at the end of their working day. Some, as in other occupations, may be dehydrated at the start of their working day. This is likely to be associated with impairment in cognitive performance at the end of the working day compared to the beginning and expected to be more pronounced after a night shift. There may be less noticeable difference amongst nursing staff given the protected break time. Dehydration and associated impairment in cognition is of important clinical value as it can impact patient care. participants will be involved in the study for two shifts (one day and one night), aiming at 15 medical and 15 surgical nurses as well as 15 medical (total 15 day and 15 night shifts from each group) and surgical doctors (total 15 day and 15 night shifts from each group). Those that do not work both day and night shifts will participate for only one shift and a new participant will be recruited until target number of shifts is achieved.
The study will aim to determine normal daily variation of the individual hydration level in longitudinal study on elderly in assisted living facility and assess a range of variation of individual hydration baselines for elderly in a normal physiologically hydrated state.
The study will aim to evaluate the correlation between changes in ultrasound velocity and measures of hydration status including urine specific gravity, plasma and urine osmolality in male and female young adults after undergoing an acute dehydration and rehydration. The study will also test the hypothesis that body dehydration is a generalized physiological process equally affected all body muscles by comparing the data obtained on calf and biceps muscles.
The investigators studied laboratory measurements and previously identified risk factors to identify factors predictors of early deterioration following stroke. A prospective observational study of 196 patients with first-time acute ischemic stroke was performed. Following multivariate analysis, only a Bun/Cr >15 was independent predictor of SIE. These patients were 3.41-fold more likely to have SIE (P=0.008). The elevated Bun/Cr ratio indicates relative dehydration of the patients. An immediate intervention for such patients should be the maintenance of proper hydration.
The purpose of this study is to examine and compare the rehydration effect of Essentia Water, an electrolyzed high-pH bottled water, with industry-standard bottled water purified by reverse osmosis with minerals added, on (1) whole blood viscosity, (2) plasma osmolality, (3) bioelectrical impedance analysis, and (4) body mass change, using serial measurements in apparently healthy adults following exercise-induced dehydration in a controlled environment.
