Universidade Estadual Paulista, Via de acesso Paulo Donato Castelane, Jaboticabal, SP 14884‑900, Brazil. E-mail: singaretti@fcav.unesp.br The objective of this research was to determine in necropsied dogs the best time for fixation in ethylic alcohol (EA) and preservation in 30% sodium chloride aqueous solution (SCAS 30%), aiming micro-surgical training. Five groups of necropsied dogs (G1 to G5) were fixed with EA, and put in boxes containing EA for 30 (G2), 60 (G3), 90 (G4) or 120 days (G5). After that, each group was preserved in SCAS 30% for 120 days. The control group (G1) was composed by cadavers without fixation/preservation. At the end of each period, two fragments of external jugular vein per cadaver were collected, for traction test. Immediately after the collection, the cadavers femoral veins were evaluated (by 2 people) regarding the suture quality in binocular surgical microscope, and attributed scores from 0 (bad) to 5 (excellent), regarding the fresh samples. The average at the maximum rupture strength of the G3 fixation end (21.51N), such as the average of the G2 preserving end (21.62N) remained closer to the control group (19.98N) and the G2 was the group with the best score for venous suture training. The EA was efficient as a fixative just like SCAS as a dog cadavers’ preservative. The small change of the traction test values, together with the best suture score, indicated the group kept for 30 days in EA and SCAS (G2) as the best for venous micro-surgical training.

RESUMO.- Pelógia M.E.S., Cerqueira E.S.F., Silveira C.P.B., Rolim G.S., Fechis A.D.S., Rocha T.A.S.S., Laus J.L. & Oliveira F.S. 2018.

E-mail: singaretti@fcav.unesp.br O objetivo deste trabalho foi determinar, em cadáveres de cães, o melhor tempo para fixação em álcool etílico (AE) e conservação em solução aquosa de cloreto de sódio (SACS) a 30% visando o treinamento microcirúrgico. Cadáveres de cinco grupos (G1 a G5) foram fixados com AE e colocados em caixas contendo AE por 30 (G2), 60 (G3), 90 (G4) ou 120 days (G5). Depois, cada grupo foi conservado em SACS 30% por 120 dias. O grupo controle (G1) foi composto de cães sem fixação/conservação. Ao final de cada período, 2 fragmentos da veia jugular externa por cadáver foram coletados para o teste de tração. Imediatamente após a coleta, as veias femorais foram avaliadas (por 2 pessoas) em relação à qualidade da sutura em microscópio cirúrgico binocular, e atribuídos escores de 0 (péssimo) à 5 (excelente), em relação às amostras frescas. A média da força máxima de ruptura no G3 no final da fixação (21,51N), assim como a média do G2 no final da conservação (21,62N) foram as que mais se mantiveram próxima do grupo controle (19,98N) e o G2 foi o grupo com o melhor escore para treinamento da sutura venosa. O AE foi eficiente como fixador assim como a SACS foi efetiva na conservação de cadáveres de cães. A pequena alteração nos valores do teste de tração, junto com o melhor escore para sutura, indicaram o grupo mantido por 30 dias em AE e SACS (G2) como o melhor para treinamento venoso microcirúrgico.


#2 - Avaliação hemogasométrica em cães submetidos à pneumonectomia esquerda, p.345-351

ABSTRACT.- Binoki D.H., Jatene F.B., Fantoni D.T., Stopiglia A.J., Santos A.L.S., Freitas R.R., Simões E.A., Irino E.T., Monteiro R. & Lofiego R. 2007. [Hemogasometric evaluation in dogs submitted to left pneumonectomy.] Avaliação hemogasométrica em cães submetidos à pneumonectomia esquerda. Pesquisa Veterinária Brasileira 27(8):345-351. Departamento de Cirurgia, Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, São Paulo, SP 05508-270, Brazil. E-mail: stopa@usp.br It is well known that different diseases of infectious, traumatic or neoplasic origin can occur in the lungs of dogs, and pneumonectomy technique may be an option for the treatment of some of these diseases. The objective was to evaluate hemogasometric parameters, oxygen partial pressure (PaO2), carbon dioxide partial pressure (PaCO2), hydrogen ion concentration (pH) and bicarbonate ion concentration on the pre- and post-operative moments of the left pneumonectomy. Eighteen adult mongrel dogs, males and females, were randomly distributed into two groups with 9 dogs each. In Group A, the left bronchial stump of the dogs was sutured manually with polypropylene 5-0, and, in Group B, the left bronchial stump of the dogs was sutured mechanically with a surgical stapler. The data were collected at 6 moments: Before the pre-anesthetic administration (T0), one hour after the extubation (T1EXT), 48 hours after the surgery (T48h), 7 days after the surgery (T7d), 15 days after the surgery (T15d), and 36 days after the surgery (T36d). The results were statistically analyzed. PaO2 values of Group A on T1EXT (67.00±11.31) were significantly lower in relation to T0 (99.4±18.34), a fact that did not happen in Group B: T1EXT (87.00±8.35) in regard to T0 (87.00±7.55). There was no difference on pH values in dogs of Group A, but in Group B was observed a decrease on T1EXT (7.3644±0.0353) in relation to T0 (7.4189±0.0136), although the animals did not develop acidosis. It was concluded that dogs submitted to left pneumonectomy (sutured manually or sutured mechanically of left bronchial) did not show immediate and mediate acid-basic instability during the study.
