There are no studies on the evaluation of the guided insertion of LMA Protector\n TM<\/jats:sup>\n to achieve adequate gastrointestinal drainage function.\n <\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n This randomised study included 132 patients who underwent surgery under general anaesthesia. The gum elastic bougie (GEB)-guided insertion of LMA Protector\n TM<\/jats:sup>\n (group I) was compared with the conventional method (group II), and the alignment of the tip of the drain tube with the oesophagus was assessed. The insertion characteristics of the device, accuracy of LMA Protector\n TM<\/jats:sup>\n placement, haemodynamic parameters, and post-operative airway morbidity following the insertion of the device were also compared between the two groups.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The first-attempt success rate for the placement of LMA Protector\n TM<\/jats:sup>\n and the patency of oesophagus was higher in group I patients than in group II (100% vs 84.8%;\n P<\/jats:italic>\n < 0.001). However, the time taken for device insertion and associated haemodynamic changes were significantly longer in group I. The patients in group I had better visualisation of laryngeal structures. The GEB-assisted insertion of LMA Protector\n TM<\/jats:sup>\n resulted in less incidence of blood staining at the cuff of the device.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n \n GEB-guided insertion of LMA Protector\n TM<\/jats:sup>\n achieved better oesophageal patency than the conventional insertion method. This method also had higher first-attempt success at the placement of the device and was observed to be less traumatic.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ija.ija_604_23","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T13:01:05Z","timestamp":1700485265000},"page":"S238-S244","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of gum elastic bougie-guided insertion of LMA ProtectorTM versus the conventional method in achieving oesophagal patency - A randomised comparative study"],"prefix":"10.4103","volume":"67","author":[{"given":"Sukhyanti","family":"Kerai","sequence":"first","affiliation":[{"name":"Department of Anaesthesiology and Intensive Care, Maulana Azad Medical College and Associated Hospitals, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
