The Organ Procurement and Transplantation Network says 31 children under age 11 are on the waiting list for a lung transplant.
The network added Murnaghan to the adult waiting list after Baylson's ruling. Her transplant comes just two days before a hearing was scheduled on the family's request for a broader injunction.
Critics warn there could be a downside to having judges intervene in the organ transplant system's established procedures. Lung transplants are difficult procedures and some say child patients tend to have more trouble with them than adults.
The national organization that manages organ transplants this week resisted making emergency rule changes for children under 12 who are waiting on lungs but created a special appeal and review system to hear such cases.
