To the Editor : Re your March 20 editorial '' Rescuing the Medical Center '' : We believe that any discussion of Westchester Medical Center 's future must explain what will be lost if it does not survive : the only Level I trauma center between New York and Albany ; the only burn center between New York and the Canadian border ; the only pediatric intensive care unit and highest-level neonatal intensive care unit ; and the only 24-hour , full-service cardiac care center between New York and Albany , offering lifesaving diagnoses , treatment and surgeries .
