Anesthesia for the child with an upper respiratory infection (URI) presents a challenge for the pediatric anesthesiologist. Differences in study design have made interpretation and comparison very difficult. The general lack of evidence-based research has led to disparities in the manner in which children which URI have been traditionally managed. Many studies have described associations between URIs and adverse events and we must decide whether to proceed or postpone the procedure and how long to postpone it. More recent research, however, suggests that children with uncomplicated infections can undergo elective procedures without significant increase in adverse anesthetic outcomes. This presentation summarizes the evolving literature about cancellation of surgery for the child with an upper respiratory infection, perioperative outcomes and anesthetic management.
