Thoracotomy in the horse | Toracotomia em eqüinos
1999
Raquel Yvonne Arantes Baccarin | José de Alvarenga
Six healthy equine were used to evaluate surgical technique of thoracotomy; surgical access to the right hemithorax was assured by anesthesia with mechanical controlled ventilation. The technique employed resulted in intense and diffuse bleeding throughout the muscular layers and provided easy approach to elevate the periosteum of the rib to be partially excised. After undoing of the negative thoracic pressure, pulmonary expansion was adequate, as assessed by visual examination. The bone endings provided good support and stability to the muscular sutures, and the suture material was of enough strength to support different degrees of tension. The technique allowed surgical procedures to be carried out in the horse’s cranial and accessory pulmonary lobes as well as satisfactory exploration of the right pleural cavity. The suture methods employed were efficient and no signs of respiratory distress or pneumothorax were observed. | Foram utilizados 6 eqüinos hígidos, sob anestesia com ventilação controlada, para a realização de acesso cirúrgico ao hemitórax direito com o objetivo de se avaliar a técnica cirúrgica empregada, mediante a utilização de anestesia com ventilação controlada mecânica. A técnica de toracotomia provocou sangramento difuso intenso nas camadas musculares; o descolamento do periósteo da costela a ser parcialmente excisada foi realizado facilmente; após a pressão negativa intratorácica ser desfeita, a expansão pulmonar manteve-se visualmente adequada; os cotos ósseos forneceram bom suporte para os músculos da região e tornaram a síntese cirúrgica mais estável; e, o fio de sutura utilizado na musculatura mostrou força de tensão suficiente para suportar os diferentes graus de tração. Concluiu-se que a técnica cirúrgica empregada permite a realização de procedimentos cirúrgicos nos lobos pulmonares cranial e acessório e boa exploração da cavidade pleural direita e que a técnica de sutura empregada é eficiente, pois não causa transtornos respiratórios ou sinais de pneumotórax.
