Video Laryngoscopy Versus Direct Laryngoscopy for Nasotracheal Intubation

The aim of this study is to perform a pilot study investigating the first attempt intubation success rate differing between video laryngoscope nasotracheal intubation and direct laryngoscope nasotracheal intubation. The study population will consist of 60 neonates and infants with congenital heart disease less than 1 year of age who need nasotracheal intubation during general anesthesia for cardiac procedures. Standard nasotracheal intubation will be performed using either a video laryngoscope or direct laryngoscopy. Neonates and infants will be randomly assigned (1:1) to standard video laryngoscopy (with one of the following systems: Storz C-MAC Miller Video Laryngoscope, Karl Storz, Tuttlingen, Germany or Mc Grath Video Laryngoscope, Medtronic, Boulder,USA) or to direct laryngoscopy with one of the following blades: Miller or Macintosh (Heine, Hersching, Germany).

Inclusion criteria. * Age less than 1 year * Congenital heart disease * Scheduled for cardiac surgery * Planned postoperative ICU stay Exclusion criteria * Nostrils not suitable for nasotracheal intubation * Bleeding during dilation of nostrils
