Patients with autism spectrum disorder are a heterogeneous group and often need general anesthesia for different procedures and studies. Familiarity with each patient's behavioral specifics and efforts to alleviate stress is of paramount importance for a smooth perioperative course with minimal adverse events.

Our study offers the most comprehensive analysis of emergent perioperative calls for help in pediatric anesthesia to date. We identified several characteristics, independently associated with more complicated and frequent perioperative STAT calls. Further research is required to evaluate the utility of this information in preventing and treating adverse events in children undergoing surgery and anesthesia.
