This prospective investigation from the University of Michigan Health Systems sought to determine the risk factors for adverse respiratory events in children with upper respiratory infections (URIs) undergoing elective surgical procedures. The study sample consisted of 1,078 children aged 1 month-18 years scheduled for elective surgery with general anesthesia (61 declined participation, 73 canceled surgery). Parents completed a short questionnaire that dealt with demographics as well as the presence and severity of URI symptoms. The following adverse respiratory events were tracked prospectively: laryngospasm, bronchospasm, breath holding >15 sec., oxygen saturation <90%, or severe cough. Follow-up by phone was done between 710 days post-operatively. Complications were scored according to severity from 1 (no complication) to 4 (most serious).1
Children were assigned to 1 of 3 groups depending upon the presence or absence of URI symptoms: active URI, recent URI, and control. In order to be in the URI group a child had to exhibit a minimum of 2 URI symptoms with parental confirmation. URI symptoms in this study included: scratchy or sore throat, rhinorrhea, sneezing, nasal congestion, malaise, cough, or temperature >38C. The recent URI group included those who did not fulfill the URI
