Background: This study was designed to find appropriate lubricant for streamed lined liner of pharyngeal airwayTM (SLIPATM). We evaluated the incidence of sore throat, nausea, vomiting, hoarseness, paresthesia and blood stain after us-ing saline, water soluble gel and 2% lidocaine gel as a SLIPATM lublicant. Methods: One hundred twenty three patients scheduled for minor surgery to whom the SLIPATM was considered suit-able were randomly allocated to one of three groups which receive normal saline, water soluble gel or 2% lidocaine gel as a SLIPATM lublicant. Patients were interviewed at recovery room, post operation 6-12 hour, post operation 18-24 hour about sore throat and other complications. Results: There were no statistical difference in sore throat and blood stain among three groups. Also there were no statis-tical differences in hoarseness, nausea, vomiting. The incidence of paresthesia in 2% lidocaine gel group was significantly higher than those of the other two groups immediately after operation, but it was resolved after leaving the recovery room. Conclusions: Our results suggest that normal saline, water soluble gel and 2% lidocaine gel are all available as a SLIPATM lubricant. Size of SLIPATM, insertion technique and difficulty of insertion should be further investigated as the main causes of a sore throat and other complications which can occur after the insertion of SLIPATM.
