title: [Proposed experimental model to provide training in the management of anesthesia in liver transplantation].
abstract: OBJECTIVE
  To propose and evaluate the use of a porcine model for training in how to manage and improve the quality of anesthesia during liver transplantation.
  
  
  METHODS
  Five trained anesthesiologists who had no previous experience in managing anesthesia during liver transplantation and who did not work in hospitals where the procedure was performed volunteered for the training course and evaluated it. Each trainee anesthetized 5 animals. Surgery was performed under total balanced anesthesia with monitoring of hemodynamics, ventilation, biochemistry, arterial blood gases, and coagulation. Previously set criteria were used to evaluate the trainees' skill in maintaining patient stability. Their work was assessed 7 times: at baseline, 15 minutes into the preanhepatic phase, at the end of the preanhepatic stage, 15 minutes into the anhepatic phase, at the end of the anhepatic phase, 15 minutes into the postanhepatic phase, and at the end of the postanhepatic phase. After completing the course, the trainees filled in a questionnaire to evaluate its usefulness. Analysis of variance was applied to score changes in anesthetic quality criteria.
  
  
  RESULTS
  After implantation, changes in metabolic (acidosis) and cardiac (hypotension and bradycardia) status were the most critical abnormalities the trainees faced. Their skill in coping with hemodynamic and metabolic changes improved significantly (P<.05). All participants expressed a preference for receiving training in a porcine model before providing anesthesia in this surgical setting.
  
  
  CONCLUSIONS
  Under this training model, the anesthesiologists understood and were able to manage the hemodynamic and physiologic changes that develop during a liver transplant procedure. We believe that training using a porcine model allows an anesthesiologist to acquire experience and skill in this setting.
