Early clinical experience with a new Video Laryngoscope (SANYAR (R)) for tracheal intubation in adults: A comparison clinical study

Objective: SANYAR (R) video laryngoscope (S-VL) is a new video laryngoscope. We conducted a comparative clinical study to assess its ability to provide laryngeal exposure and facilitate endotrachetal intubation (ETI) in adult patients. Method: This comparison clinical study was conducted on adult patients undergoing elective general anesthesia. The patients were randomly divided into two groups of direct laryngoscopy (DL) or S-VL. The primary outcome was the time required for performing ETI. The glottic view and successful ETI on the first attempt was also compared between the two groups. Results: Full and partial glottic visualization was achieved in 100% of the patients in the S-VL group, while the corresponding figure in the DL group was 90%. Cormack-Lehane III was observed in 5 patients of the DL group, and ETI was successfully carried out with S-VL. The first-pass success rate of ETI was significantly higher in S-VL group compared to the DL group (94% vs. 78%; P = 0.034). The mean times to ETI were 38.32 +/- 6.4 and 35.31 +/- 8.4 seconds in DL and S-VL groups, respectively (P = 0.650). Conclusion: During ETI for general anesthesia, SANYAR (R) video laryngoscope compared with direct laryngoscopy improved glottic visualization and first-pass ETI rate.
