Disordered water metabolism: hyponatremia.

Normal osmoregulation is maintained by the proper function and interplay of factors influencing thirst, renal water metabolism, and vasopressin secretion. In pathophysiologic states, body water homeostasis is disrupted and hyponatremia ensures. Hyponatremia associated with cardiac failure, hepatic failure, respiratory failure, diabetes mellitus, the postoperative state, and other disorders is commonly found in the critical care [...]

EARLY ORAL HYDRATION AFTER CESAREAN DELIVERY PERFORMED UNDER REGIONAL ANESTHESIA.

OBJECTIVE: To establish an early, safe, and well-tolerated time to start oral hydration after cesarean delivery. METHODS: A prospective randomized trial of women delivered by cesarean under regional anesthesia at Alanya Research and Medical Center, Turkey, between 2005 and 2006. A clear liquid drink was given to 100 women in the early oral intake (EOI) [...]

Assessment of hormonal disorders of water metabolism.

Clinical disorders of water regulation are relatively common and occur with severity ranging from profound and easily recognizable disturbance of body water balance to mild and often clinically inapparent. The development of sensitive and specific radioimmunoassay procedures capable of quantitating the level of AVP in plasma and urine has allowed elucidation of the pathophysiology of [...]

Water distribution in the foetus and newborn infant.

A short survey is given over changes in water metabolism from early foetal life to infancy. The close connection between water metabolism and body composition is described as well as the changes taking place after birth. The impact of intrauterine malnutrition, delivery and postnatal nutrition is discussed. PMID: 6351536 [PubMed - indexed for MEDLINE

EFFECT OF VARIOUS STATES OF HYDRATION ON PLASMA ADH AND RENIN IN MAN

To investigate the interaction between antidiuretic hormone (ADH) and renin-angiotensin system, plasma ADH and plasma renin activity (PRA) were determined in normal subjects (n = 10) under various hydrated states. Four experimental conditions, i.e., water loading, infusion of hypertonic saline, acute dehydration induced by furosemide and postural changes, were chosen. 1. Upright posture decreased plasma [...]

Water–the major nutrient

Water metabolism is a major problem in infants of very low birth weight. Their surface is proportionally larger, they have a relatively low intracellular water volume and a high extracellular and total body volume. Kidney function is immature compared to bigger infants, and the neuroendocrine function is also immature. Finally the large surface and the [...]

MILD DEHYDRATION INDUCES ECHOCARDIOGRAPHIC SIGNS OF MITRAL VALVE PROLAPSE IN HEALTHY FEMALES WITH PRIOR NORMAL CARDIAC FINDINGS

This study was designed to investigate the hypothesis that mitral valve prolapse (MVP) can be induced after diuresis in women without the abnormality who have characteristic body habitus. Fifteen tall, slim, healthy female volunteers with a normal cardiac findings, echocardiogram, and history were investigated after mild diuresis with furosemide and after placebo. All subjects lost [...]
