Early clinical experience with a new video laryngoscope (SANYAR®) for tracheal intubation in adults: a comparison clinical study

SANYAR® 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. 

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. 

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). 

During ETI for general anesthesia, SANYAR® video laryngoscope compared with direct laryngoscopy improved glottic visualization and first-pass ETI rate.
