NCT01222169

Brief Summary

To describe respiratory and laryngeal responses to laryngeal stimulation during propofol anesthesia in children. To determine whether the co-administration of lidocaine blunts these reflex responses. The outcome of primary interest is the reflex laryngospasm. Hypotheses: I: The severity of laryngospasm evoked by laryngeal stimulation is reduced 2 min. after iv. administration on 2mg/kg lidocaine in pediatric patients anesthetized with propofol (3mcg/ml). II:The incidence of laryngospasm elicited by controlled stimulation 10min. after iv. administration of lidocaine is equivalent to the response before the administration of lidocaine.
