The McGrath® Series 5 Portable Video Laryngoscope (Aircraft Medical, Edinburgh, UK) has been designed for tracheal intubation in patient over 15 kg. It offers a visualization of the vocal cords via a liquid crystal display (LCD) screen at the top of the device's handle. Disposable curved blade are inserted on the adjustable CameraStick™(fig1). The device can be used instead of a classical size 2-4 blade. The aim of this study was to evaluate this device for non difficult tracheal intubation in children. Method: After local IRB approval and informed patients or parents consent, 30 children scheduled for elective surgery and without any predicted factors of difficult intubation were prospectively included. Intubation was performed by conventionally trained anesthesiologists. They first performed 20 attempts of intubation with the device on an airway manikin. After induction of general anesthesia, a conventional laryngoscopy (standard MacIntosh laryngoscope) was performed by a first physician who assigned a Cormack-Lehane score (group 1). Then a second physician performed the tracheal intubation using the Videolaryngoscope (fig2) and assigned a second Cormack-Lehane score (group 2). Age, weight, Cormack-Lehane scores and time to perform the intubation (from introduction between tooth to first insufflation) were recorded.[figure1]figure1 The McGrath® Series 5 Portable Video Laryngoscope and tracheal tube with stylet Results: Mean age was 63 months (15-182), Mean weight was 22 kg (range15-72). Intubation was always successfull. Median Cormack-Lehane (C-L) score was grade 1 in the two groups. In 4 children, the C-L score was grade 2 in direct laryngoscopy and grade 1 using the Videolaryngoscope. The mean time for performing intubation was 25 seconds(20-33). The oesophagus has been visualized in 24 cases.[figure2]figure 2 Tracheal intubation with visuaization of the vocal cords Discussion: The McGrath® Series 5 Portable Video Laryngoscope allows good conditions for tracheal intubation of children without predicted difficult intubation. Compare to the GlideScope® which used nearly the same curved blades, tracheal catheterism was not difficult. It minimize the lifting forces that are necessary to perform the laryngoscopy. Its interest in difficult intubation needs to be evaluate. Anesthesiology 2008; 109 A785 |
