This situation was recently dramatized by the television show The Good Doctor. The ethical anguish there was compounded by making the patients old enough to tell the surgeons that they would rather sacrifice their own life to save their sister, than to be the sole survivor--who would then live only because her sister and lifelong constant companion is dead. The scriptwriters also stirred the pot by putting one in a coma to remove the possibility of explicit consent. At the time, it stretched my suspension of disbelief.
