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

Objective: 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. 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® video laryngoscope compared with direct laryngoscopy improved glottic visualization and first-pass eti rate.
