Schiavo on Morphine to Relieve Pain - Pain in a PVS State?

My Way News: "Schindler said he feared the consequences of morphine that has been used to relieve his daughter's pain.
'I have a great concern that they will expedite the process to kill her with an overdose of morphine because that's the procedure that happens,' he said.
Felos disputed that, saying that hospice records show Schiavo was given two low doses of morphine - one on March 19 and another on March 26 - and that she was not on a morphine drip. The records show that the second dose was given after nurses noticed 'light moaning and facial grimacing and tensing of arms,' he said.
Hospice spokesman Mike Bell said federal rules kept him from discussing Schiavo specifically, but said 'a fundamental part of hospice is that we would do nothing to either hasten or postpone natural death.'
Comfort measures, including morphine drips, are used in consultation with a patient's guardian, physician and hospice care team, Bell said."
