Videolaryngoscopic evaluation of hypopharyngeal lesions caused by PLMA and I-gel: A Randomised Controlled Clinical Trial.

Their influence on the hypopharyngeal mucosa have not been evaluated before under videolaryngoscopy. Methods: One hundred ASA I-II patients, aged 18–70 years who underwent elective surgery were randomly allocated for airway management with the I-gel or ProSeal laryngeal mask airway. Mucosal oedema, mucosal colour change and nodularity were evaluated with videolaryngoscopy. Insertion times, oropharyngeal leak pressure and complications were assessed. Results: For the ProSeal laryngeal mask airway, the mean insertion time (28 ± 15 vs. 18 ± 9.91, P < 0.001) and oropharyngeal leak pressure at the time of insertion (27 ± 7 vs. 23 ± 5, P = 0.01) were significantly higher than the I-gel. With the ProSeal laryngeal mask airway, the incidences of dysphagia were higher at 1 and 12 hours postoperatively (30% vs.12%, P = 0.024) and (16% vs. 4%, %, P = 0.046). A significant relationship was found between hypopharyngeal hyperemia and dysphagia (P = 0.001). Conclusion: The use of the I-gel resulted in fewer complications than the ProSeal laryngeal mask airway and seems to be advantageous over the ProSeal laryngeal mask airway in adults under general anaesthesia.eninfo:eu-repo/semantics/closedAccessDysphagiaHyperemiaHypopharynxI-gelOropharyngeal leak pressureProSeal laryngeal mask airwayVideolaryngoscopyArticleWOS:0006776784000102-s2.0-85106228719N/A10.1016/j.tacc.2021.03.012Q2
