Objective To compare the performance of the streamlined pharynx airway liner（SLIPA TM）with the conventional laryngeal mask airway（LMA）for airway management in minor surgery under general anesthesia. Methods Sixty fasted adult patients with ASA status I~II were randomly designed to establish SLIPA TM airway（SLIPA TM group）or LMA airway（LMA group）for airway management during anesthesia. Article airway handling，pharynx sealing，ventilation maintenance and adverse reactions with SLIPA TM group and LMA group were assessed. Results SLIPA TM had comparable total rate of successful insertion and airway placement difficulty to LMA（P>0.05）. Maximum seal pressure was（22±5）cm H2O and（24±6）cm H2O in SLIPA TM group and LMA group（P>0.05），respectively. A leak was noticed in 20% and 16.7% of patiemts in LMA group when patients'lungs were ventilated using intermittent positive pressure ventilation mode after airway mask placment and during surgery，and 3.3% and 0 in SLIPA TM group（P<0.05）. The incidence of sore trauma was similar in both groups. Conclusion SLIPA TM is an acceptable and alternative method for LMA，exerting similar clinical performance with easier placement，less sore trauma and more stable IPPV during minor surgery.
