Application of Proseal Laryngeal Mask Airway in General Anesthesia During Cerebral Aneurysm Embolism Surgery

Objective To explore the safety and efficacy of proseal laryngeal mask airway(PLMA) in general anesthesia during cerebral aneurysm embolism surgery.Methods 60 patients ASAⅡto Ⅲ,undergoing cerebral aneurysm embolism surgery,were randomly assigned into PLMA group(group PLMA n=30) or endotracheal intubation group(group TT n=30).MAP,HR and SpO2 were monitored before induction,1 min before and 5 min after PLMA insertion or endotracheal intubation,PLMA or endotracheal extubation and 5 min after extubation.Propofol and remifentanil usage as well as complications were recorded.Results MAP and HR of group PLMA were lower than group TT at every time points(P0.05);The dosage of propofol and remifentanil were lower in group PLMA compared with group TT(P0.05);There were no significant differences in complications between two groups.Conclusion PLMA intubation was efficient to maintein hemodynamic stable and reduce anesthetics doseage as well.PLMA was safe and efficient in general anesthesia during cerebral aneurysm embolism surgery.
