I am a doctor working both in the UK and in Baltimore. Recently I took care of a patient at a hospital in the US who was bleeding to death. Advanced cancer was consuming his body. Doctors at another hospital said there was nothing more they could do, but his family desperately wanted him to live so they brought him to our hospital.
The fistulas in his abdomen were so large, his bowels were open to the air. Blood frequently gushed out of his wounds, necessitating blood transfusions and other desperate measures. The only way to stop the bleeding was to push hard on these wounds, which inflicted excruciating pain. Despite these aggressive treatments, there was no hope of long-term survival.
His family was not ready to let him go and so they told us to take any measures possible to keep him alive. In order to do this, I would have to crack his ribs during chest compressions and electrocute him in an attempt to restart his heart. Regardless of whether we could keep the heart beating, the rest of his body would still be irreparably consumed by cancer.
