To compare a lighted intubation stylet (LIS), Storz DCI videolaryngoscope, and Macintosh laryngoscope regarding endotracheal intubation (ETI) times, the number of intubation attempts required, hemodynamic findings, and complications related to intubation-extubation. Methods: A total of 60 patients age 18-65 with American Society of Anesthesiologists score I-II and Mallampati score I-II, who were scheduled for elective surgery, were randomized into 3 groups: Group I, on which ETI was performed using the LIS; Group V, on which ETI was performed using the Storz DCI videolaryngoscope; and Group L, on which ETI was performed using the Macintosh laryngoscope. For each study group, ETI was applied by an operator who had previously performed at least 15 successful endotracheal intubations. Heart rates (HRs), mean arterial pressure (MAP), and peripheral oxygen saturation (SpO2) were recorded before and after induction, immediately, and 1, 2, 3, 4, and 5 minutes after ETI. However, ETCO2 was recorded immediately, and 1, 2, 3, 4, and 5 minutes after ETI. In addition, the number of attempts required to achieve ETI, ETI-related complications, and ETI times were noted. Potential complications were recorded immediately, and also 2 and 6 hours after extubation. Results: The demographic characteristics of the patients, ETI times, HR, MAP, ETCO2, and SpO2 did not differ between groups. Immediately after extubation, complications (stridor, coughing) were seen in 2 (10%) patients in Group L; however, they weren’t observed in other groups (p=0.362). Sore throat was seen in Groups I (n=2; 10%), V (n=1; 5) and L (n02; 10 %) (p=0.804). Two hours after extubation, sore throat was observed in one (5%) patient in both Group I and L (p=0.596). Conclusion: There wasn’t difference between the LIS, Storz-DCI videolaryngoscope and Macintosh laryngoscope with respect to hemodynamic parameters, the number of ETI trials, ETI times, and related complications.
