Endotracheal intubation with Airtraq versus Storz videolaryngoscope in children younger than two years - a randomized pilot-study Full Text
BMC Anesthesiology,

Soerensen MK et al. – No difference in the success rate of endotracheal intubation could be established in this ten patient sample of children younger than two years with a normal airway assessment scheduled for elective cleft lip/palate surgery. However, the Airtraq Optical videolaryngoscope showed a number of time related advantages over the Storz videolaryngoscope. Because of the small sample size a larger trial is needed to confirm these findings. Both devices were considered safe in all intubations.

Methods
  • Ten children aged 2years or younger scheduled for elective cleft lip/palate surgery were included.
  • The anesthesia was standardized and a Cormack–Lehane (CL)–score was obtained using a Macintosh laryngoscope.
  • After randomization CL–score and endotracheal tube positioning in front of the glottis was performed with one device, followed by the same procedure and intubation with the other device.
  • The video–feed was recorded along with real–time audio.
  • The primary endpoint was the success rate, defined as intubation in first attempt.
  • Secondary endpoints were the time from start of laryngoscopy to CL–score, tube positioning in front of the glottis, and intubation.

Results
  • Two intubation attempts were needed in two of five patients randomized to the SVL.
  • The difference in time (SVL vs. AOL) to CL–score was 4.5sec (p=0.0449).
  • The difference in time (SVL vs. AOL) to tube positioning was 11.6sec (p=0.0015).
  • Time to intubation was 29.0sec for SVL and 15.8sec for AOL.
