Use of the laryngeal mask in the pediatric cardiovascular intervention operation

Objective To approach the efflicacy of anaesthesia with laryngeal mask (LMA) in pediatric cardiovascular intervention operation. Methods A lotal of 40 patients had been treated with pediatric cardiovascular interventional operation. All patients had no respiratory infection history. They were randomly divided into 2 groups which were the LMA group (group Ⅰ, n=20) and the tracheal tube (TI) group (group Ⅱ,n=20). All patients were given the dose of ketamine 1 mg/kg, midazolam 0.1 mg/kg and propofol 1 mg/kg prior to insertion of laryngeal mask in group Ⅰ and maintain spontaneously breathing during operation. Patients in group Ⅱ were given the dose of Cisatracurium 0.1 mg/kg and Skelaxin before endo tracheal intubation.All patients were given a maintainence dose of propofol 1-2 mg/kg and sevoflurane 1%-1.5%.HR, MAP, SPO2 before anesthesia induction, before and after laryngeal mask insertion and after removal of the laryngeal mask were recorded. Complications of insertion LMA/TT and removal LMA/TT, the time of extubate and the time of awake were recorded completely. Results All patients were operated satisfactorily with the two ventilation methods.LMA showed less stimulate to patients′ circulation, previllege of removed immediately at the end of operation and shorter stay in recovery room. Conclusions LMA can be used efflicacy for pediatric cardiovascular intervention operation.
