The LMA® ProtectorTM in anaesthetised, non‐paralysed patients: a multicentre prospective observational study

The LMA® ProtectorTM in anaesthetised, non‐paralysed patients: a multicentre prospective observational study

Summary We evaluated the LMA® ProtectorTM in 280 ASA physical status 1–3 patients aged 18–75 years by assessing the ease of insertion, insertion time, oropharyngeal leak pressure, ease of gastric tube passage and complications. First‐attempt and overall insertion success was 234/280 (84; 95%CI 79–88...

Zusammenfassung:Summary We evaluated the LMA® ProtectorTM in 280 ASA physical status 1–3 patients aged 18–75 years by assessing the ease of insertion, insertion time, oropharyngeal leak pressure, ease of gastric tube passage and complications. First‐attempt and overall insertion success was 234/280 (84; 95%CI 79–88%) and 274/280 (98; 95–99%). Median (IQR [range]) insertion time was 17 (12–25 [5–44]) s, and manoeuvres to facilitate insertion were required in 56 (50–63)% of patients. Median oropharyngeal leak pressure was 31 (26–36 [14–40]) cmH2O. Multivariate analysis identified two risk factors for oropharyngeal leak pressure
