PHILADELPHIA -

The mother of a 10-year-old Delaware County girl recovering after a double lung transplant says doctors tried to remove her breathing tube but were forced to reinsert it.

Janet Murnaghan said in a statement provided by a spokeswoman that her daughter, Sarah, ``could not handle the reduced support'' after the tube was removed Wednesday.

She called the day ``excruciating'' and said it was ``impossibly painful'' watching her daughter struggle to breathe, so the girl was ultimately sedated and re-intubated.

Janet Murnaghan said doctors have assured the family that the day's events don't change Sarah's long-term prospects but just mean ``she needs more time to regain her strength.''

Sarah, of Newtown Square, suffers from severe cystic fibrosis. She underwent the operation after a national debate over the organ allocation process.
