Avaliação da função glomerular de cães sadios e nefropatas sob estimulação dopaminérgica

Dopamine is an endogenous compound widely used in intensive care. It has a broad spectrum of action, on the cardiovascular system and urinary tract. Increased glomerular filtration rate, renal blood flow and fractional excretion of sodium and phosphorus are expected renal effects in normal individuals, but are poorly explored in veterinary medicine. This study was conducted to evaluate the glomerular function of dogs with renal disease submitted to continuous infusion of dopamine. Different doses of dopamine were administered in healthy and nephropathic dogs. Laboratory evaluations of creatinine clearance and urinary protein/creatinine ratio were performed during and after treatments. Creatinine clearance showed dose-dependent increase in healthy dogs. In dogs with renal disease, the dose of 1μg/kg/min GFR increased slightly, without changing the urine P/C and blood pressure, while the dose of 3μg/kg/min increased urinary protein excretion.

Mau Funcionamento do Sistema de Circulação Extracorpórea: Relato de Caso

Background and objectives: The introduction of extracorporeal circulation in clinical practice was decisive for the development of modern cardiovascular surgery. Addition of new procedures and equipment, however, brings inherent risks and complications. The objective of this report is to describe a malfunction of the oxygenation system and emphasize the importance of the interaction among the medical team members to prevent errors and complications. Case Report: During valve replacement and IVC correction surgery, we observed a darker shade of red in the blood on the exit of the oxygenator. Laboratory tests demonstrated severe acidosis and hypoxemia. The entire system was evaluated, but the cause of the malfunction was not found. Measures to reduce damage were successfully instituted. After the surgery, the whole system underwent technical evaluation. Conclusions: Interaction among the medical team members, early diagnosis, and immediate intervention were fundamental for a favorable outcome. © 2011 Elsevier Editora Ltda.

Indicadores na estimativa do fluxo de digesta em bovinos de corte

single and double marker methods were compared in seven Nellore steers with average body weight 250 kg, and previously canullated in the rumen and duodenum. The animals were fitted with continuous-infusion pump that administered CoEDTA solutions intraruminally. In addition, a capsule containing Cr 2O 3, and other, containing external n-alkanes C 32, C 36 were inserted into the rumen of each steer. Internal markers indigestible neutral-detergent fiber and acid-detergent fiber (iNDF and iADF after 144 h in situ incubation) and internal n-alkanes C 31, C 33, C 35 were components of the diet. Steers were fed with palisade grass (Brachiaria brizantha cv. marandu) in two age of regrowth, 30 and 60 days. The duodenal flow experimental design was a factorial 2×2×12 while omasal experimental design was a factorial 2×2×4. Markers iNDF, CoEDTA and the combination Co+iNDF were efficacious to estimate duodenal dry matter flow whereas iNDF, iADF and the Co+iADF combination were all efficacious to predict omasal dry matter flow. In conclusion, the double marker method for estimation of omasal and duodenal dry matter flow was the most appropriate considering the ruminal fiber digestibility.
