Lactated Ringer's solution or 0.9% sodium chloride as fluid therapy in pigeons (Columba livia) submitted to humerus osteosynthesis

Abstract

The study aimed to compare the effects of intraosseous infusion of lactated Ringer's and 0.9% sodium chloride solutions on the electrolytes and acid-base balance in pigeons submitted to humerus osteosynthesis. Eighteen pigeons were undergoing to isoflurane anesthesia by an avalvular circuit system. They were randomly assigned into two groups (n=9) receiving lactated Ringer's solution (LR) or 0.9% sodium chloride (SC), in a continuous infusion rate of 20mL/kg/h, by using an intraosseous catheter into the tibiotarsus during 60-minute anesthetic procedure. Heart rate (HR), and respiratory rate (RR) were measured every 10 min. Venous blood samples were collected at 0, 30 and 60 minutes to analyze blood pH, PvCO2, HCO3 -, Na+ and K+. Blood gases and electrolytes showed respiratory acidosis in both groups during induction, under physical restraint. This acidosis was evidenced by a decrease of pH since 0 min, associated with a compensatory response, observed by increasing of HCO3 - concentration, at 30 and 60 min. It was not observed any changes on Na+ and K+ serum concentrations. According to the results, there is no reason for choosing one of the two solutions, and it could be concluded that both fluid therapy solutions do not promote any impact on acid-base balance and electrolyte concentrations in pigeons submitted to humerus osteosynthesis.

“…Burung yang berada di dalam kondisi teranestesi akan mengalami penurunan metabolisme sehingga suhu tubuhnya harus dijaga agar tetap stabil tidak sampai di bawah 38 °C (Lierz dan Korbel, 2012;Doneley, 2016). Terapi cairan diberikan untuk mencegah hipovolemia dan dehidrasi akibat kehilangan darah ketika operasi (Carregaro et al, 2015). Volume cairan infus yang direkomendasikan untuk Psittacine adalah 100 ml/kg per hari sedangkan untuk bayinya membutuhkan sekitar 2 -3 kali lebih banyak dibandingkan burung dewasa (Tully, 2011).…”
