Thus, we planned this study to compare the clinical performance of LMA Protector and LMA ProSeal in terms of OLP as a primary objective and insertion characteristics as secondary objectives.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n Ninety patients of either gender, aged 18\u201370 years, were randomised into groups PS (LMA ProSeal) and\n P<\/jats:italic>\n (LMA Protector). Following anaesthetic induction, the device was inserted as per group allocation. OLP of both devices was taken as a primary objective. Secondary objectives such as insertion time, ease of insertion, number of attempts required, fibre-optic view grading, amount of air (mL) required to get a cuff pressure (CP) of 60 cm H2O, and CP adjustment required and complications, if any, were also noted. Data were analysed using coGuide statistics software, Version 1 (BDSS Corp. Bangalore, Karnataka, India).\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The median (interquartile range) OLP was significantly higher with LMA protector than with LMA ProSeal [33.00 (27.0, 36.0) versus [29.50 (26.0, 32.0) (\n P<\/jats:italic>\n = 0.009)]. First-attempt success rate was 95.4% (42\/44) in group PS and 93% (40\/43) in group P. Insertion time, ease of insertion, and fibre-optic view grading were not different between the groups. Gastric tube placement failed in one patient in group PS and in three patients in group P (\n P<\/jats:italic>\n = 0.606). The median amount of air (mL) required to get a CP of 60 cm H\n 2<\/jats:sub>\n O was 26.5 (20, 28) in group PS and 12 (8,13) in group P (95% confidence interval [CI] =10.808\u201314.575) (\n P<\/jats:italic>\n < 0.001). At all time points, CP was significantly higher, and more CP adjustments were needed in group PS than in group P (\n P<\/jats:italic>\n < 0.001). Incidence of blood staining and post-operative sore throat at 1 and 24 h were not different between the groups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n LMA Protector provided a significantly higher OLP and less requirement of CP adjustments but comparable first-attempt success rate, mean insertion time, fibre-optic view, and gastric tube insertion as compared to LMA ProSeal.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ija.ija_403_23","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T13:00:58Z","timestamp":1700485258000},"page":"S245-S250","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Comparison of oropharyngeal leak pressure of LMA Protector and LMA ProSeal in anaesthetised paralysed patients \u2013 A randomised controlled trial"],"prefix":"10.4103","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3942-3268","authenticated-orcid":false,"given":"Mamta","family":"Bhardwaj","sequence":"first","affiliation":[{"name":"Department of Anaesthesiology and Critical Care, Pt.
