Extract

To describe respiratory and laryngeal responses to laryngeal stimulation during propofol anesthesia in children with upper airway infections. To determine whether the co-administration of remifentanil blunts these reflex responses. To test whether the co-administration of remifentanil results in a significant reduction of apnea with laryngospasm in these patients. Hypotheses: I: In children with a URI undergoing anesthesia with propofol, the incidence of apnea and laryngospasm after controlled stimulation is expected to occur 2.5 times more frequently than in children without URI (20 vs. 8%). II: The incidence of apnea and laryngospasm is diminished after administration of remifentanil.
