Randomized Controlled Trial Comparative Study
A prospective randomised controlled trial comparing tracheal intubation plus manual in-line stabilisation of the cervical spine using the Macintosh laryngoscope vs the McGrath(®) Series 5 videolaryngoscope.
Cervical spine immobilisation can make direct laryngoscopy difficult, which might lead to airway complications. This randomised control trial compared the time to successful intubation using either the Macintosh laryngoscope or the McGrath(®) Series 5 videolaryngoscope in 128 patients who had cervical immobilisation applied. ⋯ There were five McGrath laryngoscope intubation failures, three owing to difficulty in passing the tracheal tube and two to equipment malfunction. Equipment malfunction is a major concern as a reliable intubating device is vital when faced with an airway crisis.

Randomized Controlled Trial
Tracheal intubation of pediatric manikins during ongoing chest compressions. Does Glidescope® videolaryngoscope improve pediatric residents' performance?
Our objective was to test the ability of pediatric residents to intubate the trachea of infant and child manikins during continuous chest compressions (CC) by means of indirect videolaryngoscopy with Glidescope® versus standard direct laryngoscopy. A randomized crossover simulation trial was designed. Twenty-three residents trained to intubate child and infant manikins were eligible for the study. They were asked to perform tracheal intubation in manikins assisted by both standard laryngoscopy and Glidescope® while a colleague delivered uninterrupted chest compressions. In the infant cardiac arrest scenario, the median (IQR) total time for intubation was significantly shorter with the Miller laryngoscope [28.2 s (20.4-34.4)] than with Glidescope® [38.0 s (25.3-50.5)] (p = 0.021). The number of participants who needed more than 30 s to intubate the manikin was also significantly higher with Glidescope® (n = 13) than with the Miller laryngoscope (n = 7, p = 0.01). In the child scenario, the total time for intubation and number of intubation failures were similar with Macintosh and Glidescope® laryngoscopes. The participants' subjective difficulty of the procedure was similar for direct and videolaryngoscopy. ⋯ In simulated infant and child cardiac arrest scenarios, pediatric residents are able to intubate the trachea during CC. The videolaryngoscope Glidescope® does not improve performance in this setting.
