Endotracheal intubation with Airtraq versus Storz videolaryngoscope in children younger than two years - a randomized pilot-study
BMC Anesthesiology, 05/04/2012
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.
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.
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.
