Purpose: To study the effects on the water, electrolyte, and acid-base balances in rabbits submitted to antegrade enema with different solutions through appendicostomy. Methods: Forty male New Zealand rabbits were submitted to appendicostomy, and distributed in 4 groups, according to the antegrade enema solution: PEG group, polyethylene glycol electrolyte solution (n=10); ISS group, isotonic sa...

INTRODUCTION Although experience within Peru suggests clinical and physiological benefits of treating dehydration caused by diarrhoea with Lactated Ringer's solution (LR) over sodium chloride 0.9%, (NaCl) there is little documented scientific evidence supporting this view. It is important to clarify this issue and determine the best solution for use during epidemics. METHODOLOGY Forty patient...

AIM Dysnatremic cases are frequently faced in clinical practice and the macroscopic effects of it and its consequences are well known, but microscopic effects of it are not well defined, this research tries to reveal the effects of dysnatremia at the cellular level. MATERIAL AND METHODS By using an action potential simulation, the effects of the extracellular sodium concentration on the sodiu...

AIM The aim of work was presentation of several socio-demographic, clinical and laboratory characteristics of gastroenteritis caused by rotavirus. THE EXAMINEES AND METHODS The examinees were children under the age of five years treated at the Pediatric Clinic due to acute gastroenteritis caused by rotavirus. Rotavirus is isolated by method chromatographic immunoassay by Cer Test Biotec. RE...

The purpose of the present study was to determine whether Na(+)-H+ and Na(+)-Ca2+ exchanges modulate postischemic recovery of excitation-contraction coupling. Experiments were performed in 43 isolated isovolumic dog hearts perfused with blood (pH 7.40, 141 mmol/L Na+, 34 degrees C, paced at 2 Hz). A 3 x 3-mm region at the left ventricular (LV) apex was loaded with aequorin for monitoring [Ca2+]...

140 hypernatermic dehydrated infants aged 2-24 months, were hospitalized during at 21 month period. they were treated with oral electrolyte solutions a and b in which the concentration of sodium and potassium was equal (50 mmol/l sodium and 30 mmol/l potassium) but he sodium bicarbonate content differed. the serum sodium concentration returned to normal 48 hours after treatment. seven cases bec...

BACKGROUND About 1% of patients admitted to the Emergency Department (ED) have hypernatremia, a condition associated with a mortality rate of 20 to 60%. Management recommendations originate from intensive care unit studies, in which patients and medical diseases differ from those in ED. METHODS We retrospectively studied clinical characteristics, treatments, and outcomes of severely hypernatr...
