How was the deliberate cut in the cava entered in the patient's chart. As an 'accident'? Or left out as in "if it isn't charted, it didn't happen." Also, isn't it malpractice for a doctor to intentionally injure a patient. Or does the hospital consent form allow such actions if used for teaching purposes. Regardless that the experience benefited you, or that the patient recovered, it just seems so wrong to willfully conduct such an experiment on a clueless, unconscious patient with no stake in the game.
