We examined the effects of active dehydration by exercise in a hot, humid environment on anaerobic muscular power using a test-retest (euhydrated and dehydrated) design. Seven subjects (age, 27.1 +/- 4.6 years; mass, 86.4 +/- 9.5 kg) performed upper and lower body Wingate anaerobic tests prior to and after a 1.5-hour recovery from a heat [...]
OBJECTIVE: To describe the frequency of dehydration as a medical cause of acute abdomen. DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: The study was conducted at Combined Military Hospital, Malir Cantonment Karachi between March 1, 2000 to March 1, 2002. SUBJECTS AND METHODS: All the patients reporting with abdominal pain to the surgical [...]
AIM: This article reviews the literature on how important water is to the world's elderly population. BACKGROUND: Water is a finite resource, so we must preserve the water that we have. Physiological aspects and what water requirements our bodies maintain sum up this essential nutrient for life. Dehydration is a concern in the elderly. CONCLUSIONS: [...]
Dehydration in clinical practice, as opposed to a physiological definition, refers to the loss of body water, with or without salt, at a rate greater than the body can replace it. We argue that the clinical definition for dehydration, ie, loss of total body water, addresses the medical needs of the patient most effectively. There [...]
OBJECTIVE: To study the effects of dehydration, by using the indices of prerenal azotemia and orthostasis, on the rehabilitation outcomes of elderly orthopedic patients. DESIGN: Prospective, pilot study. SETTING: Regional inpatient rehabilitation center. PARTICIPANTS: A consecutive sample of 39 patients (29 women, 10 men), ranging in age from 58 to 94 years (mean, 78y), of [...]
This study examined the effects of ingesting beverages of varying electrolyte-carbohydrate (ECHO) composition on hydration, sensory response, physiological function, and work performance during 4 hours of simulated industrial work for subjects wearing impermeable protective clothing (PC). Male subjects (N=18) completed four separate work sessions. Each session consisted of 30 min of treadmill walking with intermittent [...]
INTRODUCTION: The aim of this study is to investigate the amount of water loss and percentage dehydration experienced during 1 hour of paddling on the kayak ergometer so as to help coaches and athletes tailor a suitable and adequate rehydration regime. Also, rehydration efficacy between water and a well established, commercially available sports drink (Gatorade, [...]
The authors used a quasi-experimental treatment and control group design with 49 participants from four nursing homes to test the effectiveness of an 8-week hydration intervention in reducing hydration-linked events (HLEs). A Kaplan Meier survival curve with log rank test was calculated to determine incidence and time to occurrence of a HLE. Incidence of and [...]
Several reports during the past 15 years have described hyponatremia as a result of excessive water intake by athletes during endurance races. The high rates of fluid consumption have been attributed to the desire of athletes to prevent heat injury. The military has adopted guidelines for programmed drinking to maintain performance and minimize the risk [...]
The purpose of this pilot study was twofold: 1) to determine whether there was a statistically significant difference in nursing-sensitive patient outcome ratings from admission to discharge, and 2) to describe nursing interventions used to care for children admitted with a primary diagnosis of dehydration to a 272-bed Midwestern community hospital. Twenty-nine patient care records [...]
