IRINO, Eduardo T. et al. Avaliação eletrocardiográfica em cães submetidos à pneumonectomia direita. Pesq. Vet. Bras. [online]. 2009, vol.29, n.8, pp.599-604. ISSN 0100-736X.

The purpose for using lobectomy or pneumonectomy in dogs and cats, is to cure or palliate of bronchopulmonary diseases whenever conservative clinical treatment proves ineffective. Considering the marked changes caused by pneumonectomy, new experimental studies have to be done to assess the advantages of this surgical intervention allow its performance without any risk. The aim of the current study was to evaluate the electrocardiographic alterations in ten adult mongrel dogs of both sexes with between 10 and 30 Kg that were submitted to right pneumonectomy. The clinical parameters of the dogs were evaluated in a daily basis and the alterations in every electrocardiogram derivation were recorded. All dogs presented a good post-operative outcome. In most cases there were no electrocardiographic alterations; when these alterations were observed they were of no clinical significance and included premature ventricular complexes in one dog, most likely resulting from a cardiorespiratory arrest that was reverted to successfully, and a decreased width in the QRS complex amplitude on the first 0-14 days post surgery which returned to normal after sixty days post surgery.

Keywords : Pneumonectomy; cardiology; electrocardiogram; dogs.
