The Effectiveness Of The SLIPA Compared With The Conventional Laryngeal Mask Airway In Upper Respiratory Tract Management

Objective:We compared the SLIPA with the conventional laryngeal mask airwayLMA regarding handling, safety, sealing of the pharynx, and patient comfort in 124 adult patients (ASA I–III) undergoing ophthalmic surgery under general anesthesia。Methods: We have 124 patients undergoing ophthalmic surgery were randomly divided into two groups . SLIPA with traditional LMA group, recorded the two groups were ease of insertion , Maximum seal pressure , rate of gastric air insufflation , sore throat , Blood traces mucous , and statistical analysis .Results: We studied 124 consecutive patients (64 men, 60women) with ASA physical status I–III presenting for ophthalmic surgery. Data from all patients were included in the analysis . Sixty-five patients were randomized to LMA and 59 patients were randomized to SLIPA . There were no differences between groups with the rate of successful insertion and ease of insertion. There is little difference into the throat of the seal (Table 1). However, there is obviously gastric insufflation observed in SLIPA(19% vs 3%; p<0.05). Complaints of a sore throat were noticed at a significantly higher rate in the LMA group than in the SLIPA group(14% vs 3%; p<0.05)(Table 1).Conclusion:There were no differences between groups with the rate of successful insertion and ease of insertion. However, there is obviously gastric insufflation observed in SLIPA. Should be alert to the danger of aspiration. Complaints of a sore throat were noticed at a significantly higher rate in the LMA group than in the SLIPA group. Recommended the application of LMA to avoid excessive air pressure. As far as possible to shorten the operation time.
