Abstract

Introduction: Maintenance of airway patency is very important and one of the responsibilities of the anesthesiologist is patency of the airway for maintaining lung ventilation. Endotracheal entubation has remained one of the crucial difficulties during elective and emergency surgical operations. Videolaryngoscope is a new modality among the airway management procedures. It has been used in various difficult airway conditions by providing a glottic view without an alignment of the oral, pharyngeal and laryngeal axes. The aim was to compare the two methods of videolaryngoscopy (VL) and direct laryngoscopy (DL) for airway management of patients candidate for elective surgical operations. Materials and methods: This clinical trial was performed on 100 patients with an age range from 15 to 70 years, ASA class I and II. These patients were candidate for an elective scheduled operation under general anesthesia with endotracheal intubation. Assignment of patients to VL and DL was in an alternating sequence of one VL and next DL. For the patients candidate for direct DL with a number 3 MacIntosh blade evaluation was done with the VL in order to define the glottic view grading, after this endotracheal intubation was performed with DL. Almost similarly in the group for VL intubation the first glottic view grading evaluation was done with a DL thereafter the second glottic view grading evaluation with the videolaryngoscope and then endotracheal intubation was performed with a videolaryngoscope in this group. The duration of intubation was recorded. Results:Evaluation of DL patients' airway revealed that 53 were airway grade I and 47 were grade>I. From the grade>I patients 29 had grade II, 16 grade III and 2 patients were grade IV. In the VL group 82 had grade I, 16 had grade II, one grade III and one grade IV. Assessment of the glottic view airway gradings revealed an improvement using the videolaryngoscope, which was as follows; grade II to grade I in 27 patients, grade III to grade II in 13 patients and grade IV to grade III in one patient. The mean gradings of the glotic airway views with VL was 1.21±0.49 and with DL1.61±0.81. There was a significant difference between the gradings of these two groups statistically. The mean time duration for intubation for VL group was 12.96±4.22 and for DL 10.06±1.95. The difference between the time duration of these two groups was not significant statistically. Conclusion: In assessing the obtained results of the procedures done we can conclude that in viewing the glottic airway by using the VL in comparison with DL an improvement was seen and the difference between the gradings of both was significant. The time duration of intubation was not significantly longer for VL procedure group in our study.
