Effects of Anesthesia on Pediatric Surgical Patients With a History of Concussion - Phase I

The purpose of this research study is to determine the number of children who have symptoms of a concussion at the time they are scheduled for orthopedic surgery at Boston Children\'s Hospital. It is currently unknown if anesthesia affects a child with a previously diagnosed concussion. This study is the first phase of a two-part study looking at the effects of anesthesia in children undergoing orthopedic surgery with a previous concussion. Currently, the decision to continue with surgery in patients with a diagnosed concussion is based on clinical judgment by the patients.
