Objective: The purpose of this investigation was to examine the association of neck circumference (NC) with perioperative respiratory adverse events in children undergoing elective noncardiac surgery, a relationship that has not been previously characterized.
Methods: Using a prospective, observational design, we studied children aged 6 to 18 years undergoing elective noncardiac surgeries at our institution. Trained research assistants collected clinical (including perioperative adverse events) and anthropometric data from all subjects.
