Avaliação de solução eletrolítica isotônica administrada por sonda nasogástrica em bovinos adultos hígidos ou desidratados experimentalmente

Abstract

The aim of this study was to investigate the effects of composition and volume of an isotonic electrolyte solution enteral administered via small-bore nasogastric tube in continuous flow on body weight, waist circumference, moisture from feces, hematocrit, total protein, sodium, potassium , chloride, total calcium, ionized calcium, magnesium and urine specific gravity in healthy cattle experimentally or dehydrated. Four adult cattle, crossbred females were assessed and divided into two treatments in a randomized crossover. The electrolyte solution used in enteral and headquarters SEHig treatments contained 5.27g of NaCl, 3.78g of NaHCO3 and 0.3 g of KCl dissolved in 1,000mL of water. Enteral hydration was administered at a dose of 10 L h-1 for 12 hours in continuous flow. Regardless of treatment, the infusion of electrolyte solution caused an increase in body weight and abdominal circumference, decreased hematocrit, total plasma protein, potassium, total and ionized calcium, and polyuria and hyposthenuria.
