title: [Video Laryngoscopy Reduces the Incidence of Erroneous Esophageal Intubation: A Meta-analysis].
abstract: BACKGROUND
  The aim of this meta-analysis is to compare the incidence of erroneous esophageal intubations by video laryngoscopy to that by direct laryngoscopy.
  
  
  METHODS
  The systematic search, data extraction, critical appraisal, and pooled analysis were performed according the PRISMA statement. The odds ratio(OR) and 95% confidence interval (CI) were calculated by the Review Manager 5.2 software for dichotomous outcome.
  
  
  RESULTS
  Eleven trials included 1425 tracheal intubations by video laryngoscopy and 1632 tracheal intubations by Macintosh laryngoscopy. Video laryngoscopy reduced the risk of erroneous esophageal intubations (OR 0.10, 95% CI 0.04-0.24, P < 0.00001, I2 : 0%) compared with Macintosh laryngoscopy.
  
  
  CONCLUSIONS
  Our meta-analysis showed that video laryngoscopy would reduce the incidence of erroneous esophageal intubations.
