Background. Intubation is the optimal method for opening the airway and effective ventilation of the patient. However, there are occasional problems with intubation, especially in patients with injuries under pre-hospital conditions. Therefore, it is important to identify devices, e.g., videolaryngoscopes or guides, which may facilitate and shorten the procedure. This study addresses the use of a Truflex articulated guide with a videolaryngoscope.

Objectives. The main objective of the study is to evaluate the effectiveness of intubation using a Truflex articulating stylet with a McGrath videolaryngoscope, and to determine whether the average time of intubation using a Truflex articulating stylet is shorter than that using a standard intubation stylet.

Materials and methods. The study involved 43 full-time 5th year medical students. All tests were performed on training manikins with a difficult airway in January 2013. Chi-square test was used for statistical analysis with a significance level of p< 0.01. Calculations were performed using the Statistica package.

Results. Intubation using a McGrath videolaryngoscope with a Truflex articulating stylet was more effective than that using a standard intubation stylet with the same laryngoscope: 71% as compared to 40%. The mean time of successful intubation using a Truflex articulating stylet was shorter than that using a standard intubation stylet guide (31.1 ± 12.8 s and 39.8 ± 12.4 s, respectively).

Conclusions. The mean time of tracheal intubation using a Truflex articulating stylet is shorter than that using a standard intubation stylet. Intubation is also more effective when a Truflex articulating stylet is used together with a McGrath videolaryngoscope.
