The various operations employed in thoracic surgery, simple as well as complex, are easily demonstrated and performed on living anesthetized animals. In a course in thoracic surgery designed for members of the Army Medical Corps, we demonstrated the procedures, which were then performed on animals by the members of the class.
The animals (dogs) are anesthetized with intravenously administered pentobarbital sodium (35 mg. per kilogram of body weight). Adequate respiratory exchange is maintained by introducing a no. 28 (French) rectal catheter into the trachea and connecting it with a positive pressure apparatus. Should the pentobarbital sodium become ineffective, ether is administered through this apparatus. Although the operations were performed on anesthetized animals, the following discussions and descriptions of technic accompanying each procedure refer to human subjects.
