Summary: | In the present study, the effects of four different electrolyte solutions on the packed cell volume (PCV), plasma volume and plasma concentrations of total protein, sodium, potassium, chloride, total magnesium, and ionized calcium in healthy and experimentally dehydrated horses were evaluated. Four crossbred horses, two males and two females were used. In experiment 1 (E1Des) the animals were experimentally dehydrated, while in the second experiment (E2Hig) healthy equines were used. In both experiments the animals were subjected to the following treatments: SE--isotonic electrolyte solution; SEGlu--glucose-enriched SE; SEMalt--maltodextrine-enriched SE and SEMg--magnesium sulphateenriched SE. The electrolyte solutions used in all treatments were administered at 15mL [kg.sup.-1] [h.sup.-1] during 12h through small-bore nasoesophagus tube by continuous flow. The treatments with the electrolyte solutions resulted in an increase of plasma volume and a decrease in total plasma protein, hematocrit, while the electrolytes remained within the reference values. Key words: horse, fluid therapy, electrolytes, glucose, maltodextrine, magnesium sulfate. No presente estudo, foram avaliados os efeitos de solucoes eletroliticas administradas via sonda nasoesofagica de pequeno calibre sobre o hematocrito, o volume plasmatico e as concentracoes plasmaticas de proteinas totais, sodio, potassio, cloreto, magnesio total e calcio ionico de equinos higidos e desidratados experimentalmente. Foram utilizados quatro equinos adultos, mesticos, dois machos e duas femeas. No experimento 1 (E1Des), os animais foram desidratados experimentalmente, enquanto no 2 (E2Hig) foram utilizados equinos higidos. Os animais foram submetidos a cada um dos seguintes tratamentos: SE--solucao eletrolitica isotonica; SEGli - solucao eletrolitica isotonica + glicose; SEMalt--solucao eletrolitica isotonica + maltodextrina e SEMg--solucao eletrolitica isotonica + sulfato de magnesio. A solucao eletrolitica foi administrada na dose de 15mL [kg.sup.-1] [h.sup.-1], durante 12h via sonda nasoesofagica por fluxo continuo. Os tratamentos com as solucoes eletroliticas ocasionaram expansao do volume plasmatico, ocasionando a reducao nos valores das proteinas plasmaticas totais e do hematocrito, enquanto os valores dos eletrolitos avaliados permaneceram na faixa de referencia. Palavras-chave: equinos, hidratacao, eletrolitos, glicose, maltodextrina, sulfato de magnesio. |
