Comparison of proseal laryngeal mask airway and Streamlined Liner of the Pharynx Airway in the paralyzed patients undergoing gynaecologic laparoscopic surgery.

The Streamlined linear of the pharryngeal airway(SLIPA) is a new type of supralaryngeal airway(SLA), use of which has increased because it is inexpensive, disposable and easy to insert. Although other SLA(eg, laryngeal mask airway(LMA), laryngeal tube) have been used safely in elective gynaecologic laparoscopic surgery, there are few reports compare the characteristics of the SLIPA or proseal LMA(LMA-P) when used in paralyzed patients undergoing gynecologic laparoscopic surgery. We wish to provide the incidence of gastric insufflations, stability, sealing pressure and respiratory mechanics of SLIPA when used in the paralyzed patients receiving elective gynecologic laparoscopic surgery, to compare it with LMA-P. We also wish to compare the SLIPA with LMA-P in a clinical setting with regard to ease of insertion, number of repositioning attempts, and incidence or severity of sore throat.
