After my aunt had a hip surgery, she had developed an infection on the surgical sight and became worst. The orthopedic surgeon decided to undo the previous surgery for the infection to be resolve. For the mean time, my aunt was in a lot of pain. So, she was given morphine drip for the pain. My aunt had a pace maker. Then, in about a few days, I was told that the infection spread all over her body. Then, on May 10, 2011 she died because her heart stopped. Was this due to the morphine being administered to her or the infection that spread all over her body?
