“…Our data support the findings of previous manikin studies of inexperienced practitioners, using other indirect or videolaryngoscopes, such as the Airway Scope (Pentax, Tokyo, Japan) [11,12,15,16], Glidescope (Verathon Medical, Bothell, WA, USA) [14,16], and Airtraq (Fannin (UK) Ltd, Calcot, Reading UK) [9,10,13], and adds to these by showing that videolaryngoscopy can aid the teaching of direct laryngoscopy. These studies differ in some respects including the difficulty of laryngoscopy, the numbers of intubation attempts studied, and the nature and detail of instruction given before tracheal intubation was attempted.…”

SummaryDirect laryngoscopy using the Macintosh laryngoscope is a difficult skill to acquire. Videolaryngoscopy is a widely accepted airway management technique that may be easier for novices to learn. We compared the McGrath Ò videolaryngoscope and Macintosh laryngoscope by studying the performance of 25 medical students with no previous experience of performing tracheal intubation using an easy intubation scenario in a manikin. The order of device use was randomised for each student. After brief instruction each participant performed eight tracheal intubations with one device and then eight tracheal intubations with the other laryngoscope. Novices achieved a higher overall rate of successful tracheal intubation, avoided oesophageal intubation and produced less dental trauma when using the McGrath. The view at laryngoscopy was significantly better with the McGrath. Intubation times were similar for both laryngoscopes and became shorter with practice. There was no difference in participants' rating of overall ease of use for each laryngoscope.

“…19 In agreement with our results, the Glidescope has been found to increase the durations of intubation in normal and tongue edema simulations and also require increased numbers of maneuvers when intubations are performed by pediatric residents. 20 Glidescope need to be inserted in the midline of the mouth and the instructor must coordinate the tube, the monitor and the Glidescope blade together.…”

78rauma victims often need to be intubated at the scene of the trauma. Such intubation is occasionally difficult due to limited access to the patient, cervical spine injury or some factor that makes it difficult to Intubation of a Pediatric Manikin in TongueEdema and Face-to-Face Simulations by Emergency Medical Staff: A Comparison of the Glidescope, Airtraq and Direct Laryngoscopy A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Trauma victims occasionally cannot be intubated by emergency staff via conventional techniques. We sought to evaluate the efficacies of the application of the Glidescope and Airtraq in normal airway, tongue edema and face-to-face tracheal intubation models as used by emergency medical staff. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Following approval from the local human research ethics committee, 14 emergency medical staff enrolled in this study. The participants attempted to intubate pediatric manikins in three different airway models (in a random order) with a Glidescope, Airtraq and Direct Laryngoscope. R Re es su ul lt ts s: : All emergency medical staff intubated the normal and tongue edema models successfully with the three devices. The intubation success rates for the Airtraq and Glidescope were 93% with the face-to-face approach (entrapped). The intubation time with the Glidescope was longer than that for the other devices in three models (p=0.001, p=0.02, p=0.02). When compared within groups, the intubation time for the Glidescope was increased relative to the normal face-to-face approach (16 [14.0-21.5] seconds vs. 31 [18.8-34.3] seconds, 57 [43.0-71.0] seconds; p<0.001). This was not the case when we examined the other devices. C Co on nc cl lu us si io on n: : The emergency medical staff was able to intubate the pediatric manikin in the tongue edema and face-to-face models with the Glidescope and Airtraq with similar rates of success. In the Glidescope group, tracheal intubation required much more time, but this prolongation was clinically negligible.

To the Editor,In a randomized crossover trial on a mannequin simulating cardiac arrest, Shin et al. 1 showed that tracheal intubation, during chest compressions under conditions of both normal and difficult airways, was more successful with either the Pentax-AWS Ò or the GlideScope Ò videolaryngoscope (97-100% success rate) than with the Macintosh laryngoscope (75-97% success rate). However, apart from the limitations described in the Discussion section of their manuscript, we note one issue in this study which may confound interpretation of the results.In this study, the participants were inexperienced junior interns who were given a standardized 20-min training session on each of the devices before the study. The authors ignored an important issue, namely, a different learning curve is required for each of the three devices. NouruziSedeh et al. 2 showed that untrained personnel required only five tracheal intubation attempts to achieve proficiency with the GlideScope Ò in patients with a normal airway. Also, Hirabayashi 3 found that a short demonstration of the Pentax-AWS Ò and a brief practice with a mannequin were the only requirements needed to perform a tracheal intubation with the device. However, in the studies of Mulcaster et al. 4 and Konrad et al., 5 novice anesthesia residents or non-anesthesia trainees required 47-56 tracheal intubations to achieve a tracheal intubation success rate of C 90% using direct laryngoscopy. These findings suggest that less training is required to achieve proficiency with the Pentax-AWS Ò and the GlideScope Ò than with the direct laryngoscope. Furthermore, when the Pentax-AWS Ò was compared with the GlideScope Ò in both simulated normal and difficult airway scenarios, novice operators found it easier to intubate the trachea with the Pentax-AWS Ò . 6 Thus, in Shin et al.'s study, 1 identical training times for the three devices may have biased both the time required for tracheal intubation and the success rate in favour of the two videolaryngoscopes, especially for the difficult airway scenario. To be precise, the differences in the performance of the three laryngoscopes may be attributed to their different learning curves. The findings of Kim et al. support this view. 7 They studied emergency physicians-who had performed [ 50 tracheal intubations with the direct laryngoscopy on a mannequin simulating cardiac arrest-after the physicians had received only a one-hour training session with the GlideScope Ò and the Pentax-AWS Ò , and they found no significant differences between the Macintosh laryngoscope, the Pentax-AWS Ò , and the GlideScope Ò in terms of intubation time during chest compression. The different learning curves might explain the inconsistent results between studies on a mannequin simulating cardiac arrest.
