Dehydration. Evaluation and management in older adults. Council on Scientific Affairs, American Medical Association

OBJECTIVE--To review published literature regarding dehydration in older individuals and formulate a consensus on the evaluation and treatment of this unrecognized cause of hospitalizations, morbidity, and mortality. DATA SOURCES AND STUDY SELECTION--The literature concerning dehydration in the elderly population from MEDLINE was reviewed from 1976 through 1995. Search terms included dehydration, elderly, evaluation, hospitalization, and [...]

CRITERIA FOR MEASUREMENT OF DEHYDRATION.

This Position Stand provides guidance on fluid replacement to sustain appropriate hydration of individuals performing physical activity. The goal of prehydrating is to start the activity euhydrated and with normal plasma electrolyte levels. Prehydrating with beverages, in addition to normal meals and fluid intake, should be initiated when needed at least several hours before the [...]

Dehydration reduces cardiac output and increases systemic and cutaneous vascular resistance during exercise

This investigation determined the manner in which the cardiovascular system copes with the dehydration-induced reductions in cardiac output (Q) during prolonged exercise in the heat. On two separate occasions, seven endurance-trained subjects (maximal O2 consumption 4.70 +/- 0.41 l/min) cycled in the heat (35 degrees C) for 2 h, beginning at 62 +/- 2% maximal [...]

Modern management of acute diarrhea and dehydration in children.

Advances in clinical and laboratory knowledge have led to new concepts in the management of acute infectious diarrhea in children. The major advance has been the development of oral rehydration therapy, which is effective for the treatment of diarrhea of any etiology in patients of any age. Optimal management of acute infectious diarrhea includes the [...]

DEVELOPING A QUICK AND PRACTICAL SCREEN TO IMPROVE THE IDENTIFICATION OF POOR HYDRATION IN GERIATRIC AND REHABILITATIVE CARE

Dehydration has been associated with increased morbidity and mortality. Dehydration risk increases with advancing age, and will progressively become an issue as the aging population increases. Worldwide, those aged 60 years and over are the fastest growing segment of the population. The study aimed to develop a clinically practical means to identify dehydration amongst older [...]

Hypernatremic dehydration in breast-fed infants.

Three cases highlight the association between elevated breast milk sodium and hypernatremic dehydration in the infant. All three mothers, breast-feeding exclusively, had sodium levels in breast milk elevated significantly above normal. Severe hypernatremic dehydration in otherwise normal infants who are exclusively breast fed can be due to elevated sodium levels in breast milk. PMID: 7778332 [...]

Hydration status of geriatric patients in a psychiatric hospital.

Dehydration negatively impacts geriatric hospitalization outcomes. The purpose of this study was to investigate the hydration status of psychogeriatric inpatients and explore possible factors for dehydration. A descriptive, retrospective chart review of patients discharged from a psychogeriatric unit was completed. Clinical and biochemical information was collected at three time points (admission, mid-point, and discharge). Results [...]

Influence of graded dehydration on hyperthermia and cardiovascular drift during exercise.

This investigation determined the effect of different rates of dehydration, induced by ingesting different volumes of fluid during prolonged exercise, on hyperthermia, heart rate (HR), and stroke volume (SV). On four different occasions, eight endurance-trained cyclists [age 23 +/- 3 (SD) yr, body wt 71.9 +/- 11.6 kg, maximal O2 consumption 4.72 +/- 0.33 l/min] [...]
