PITTSBURGH -- -- You can stick needles in her, listen to her heartbeat and place a breathing tube in her airway. No matter what, though, baby Katie won't cry -- unless you make her.

The new pediatric simulator dubbed "Katie" was unveiled Friday at Children's Hospital of Pittsburgh. The simulator, which represents an infant from three to six months old, will be used to train critical care physicians.

Instead of beginning their training in the hospital's intensive care, the physicians will spend a month training with Katie before they begin working in situations with real patients. The training will take place at the University of Pittsburgh Medical Center's Peter M. Winter Institute for Simulation, Education and Research.

"The crucial benefit is that Katie is a simulator, so there is room for error and repetition," Dr. Ann E. Thompson, Children's chief of critical care medicine, said in a statement. "We can simply start the exercise over with an experienced physician instructing the fellow on the proper technique."

Katie, manufactured by a company called Laerdal, can simulate shock, cardiac arrest, airway difficulties, pneumonia and a collapsed lung, among other things. Physicians can perform various procedures on her.
