title: The McGrath Series 5 video laryngoscope versus the Macintosh laryngoscope: a randomized trial in obstetric patients.
abstract: OBJECTIVE
  Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope.
  
  
  METHODS
  A total of 80 obstetric patients were divided into 2 groups, orotracheally intubated with either the McGrath video laryngoscope or the Macintosh laryngoscope. The intubation times, Cormack-Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates were compared among the groups.
  
  
  RESULTS
  Intubation time in the McGrath video laryngoscope group was significantly longer than in the Macintosh laryngoscope group (P <0.01). The percentage of glottic opening was found to be higher in the McGrath video laryngoscope group (P = 0.002).
  
  
  CONCLUSIONS
  The McGrath Series 5 video laryngoscope provides excellent views during orotracheal intubation in obstetric anesthesia with normal airways.
