The application of laryngeal mask airway for general anesthesia in the interventional therapy of children with congenital heart disease

Objective To explore the effects of the application of laryngeal mask airway and compare it with traditional endotracheal intubation in children with congenital heart disease during general anesthesia.Methods Sixty children(ASA Ⅰ～Ⅱ) with congenital heart disorders,were randomly divided into two groups:laryngeal mask airway group (LMA group,30 cases) and endotracheal intubation group (TT group,30 cases).LMA was inserted followed by intravenous infusion of propofol 1.5 mg/kg and remifentanil 2 μg/kg in LMA group,while endotracheal intubation was set up following the using of propofol 1.5 mg/kg,remifentanil 2 μg/kg and rocuronium 0.6 mg/kg in TT group.Anesthesia was maintained with intravenous infusion of propofol and remifentanil.The time for operation and recovery from anaesthesia,the values of MAP,HR,SpO2 was recorded at different terms in two groups (before anesthesia,before implantation of LMA or TT,after implantation of LMA or TT,before and after the removal of LMA or TT.Also,the first successful placement was compared in two groups.Results There were no significant differences for general information in two groups,such as the time for operation and recovery from anesthesia,the values of MAP,HR,SpO2 before induction,before the LMA (TT) placed,before the removal of the LMA (TT) (P0.05).However,the values of MAP,HR,SpO2 were significantly higher in TT group than that in LMA group at application of endotracheal tube and extubation points (P0.05).Postoperative respiratory complications in LMA group was significantly lower than that in the TT group.Conclusions Application of laryngeal mask airway for general anesthesia in the interventional therapy of children with congenital heart disease not only could achieve an effect of hemodynamic-stabilization,but also reduce postoperative respiratory complications because of its less response of stress.
