Background: learning basic surgical procedures in medical school, involves acquisition of certain bloody skills. Therefore, to teach this kind of procedure on the patient is becoming more difficult nowadays. An educational alternative is proposed to teach basics surgical skills in undergraduate students in Medical School. Methods: during entire 2002, two theoretical-practical courses on Basic Surgical Maneuvers were developed in the Medicine School of UNNE. These courses were assigned to the 5 th and 6 th year's students. Used models included meet piece, bovine's bowel, heart and lungs, chick's wings; additionally live anesthetized swine and cadavers. All the students had to practice different procedures leaded by an instructor. Before performing these procedures theoretical explanation was supplied in the classroom. Attend to al least 80% of all given class, and to pass a practical final test were the only conditions to pass these courses. All the students had to fill up a survey to assess the perfomance of these courses. Results: the quota of 50 students by each course was completely covered. All the students (100%) passed successfully the courses. The survey reflected this experience as excellent (96%) or very good (4%) in teaching basic surgical procedures. Conclusion: the training in Biologic Models has shown as an excellent strategy to undergraduate surgical education. Key word: teaching-basic surgical maneuvers-bilogical models "The teaching of basic surgical skills in the biologic simulators. Undergraduate educational experience."

As reflected by our experience and the survey completed by the 30 pediatric surgeons, this empyema model in rabbits is very useful for thoracoscopic training.
