Comparison of Laryngoscope-Guided Insertion and Standard Blind Insertion of the Laryngeal Mask Airway: A Systematic Review and Meta-Analysis.

ABSTRACT: Background: The insertion of a laryngeal mask airway (LMA) using a laryngoscope-guided technique has produced inconsistent outcomes. The use of laryngoscope guidance in facilitating LMA insertion needs further investigation. This meta-analysis compared its effectiveness and safety against standard blind insertion. Method: We systematically searched PubMed, Cochrane Library, Web of Science, and Ovid Medline for randomized controlled trials comparing laryngoscope-guided (Group L) and blind LMA insertion (Group B). The primary outcome measured was fiberoptic staging. The secondary outcomes included oropharyngeal leak pressure (OLP), insertion time, success rate on the first attempt, and the incidence of postoperative sore throat and blood staining. Results: Nine RCTs (101
