Abstract

Background: Airway management and tracheal intubation in the ICU is a difficult procedure that may be concomitant with major complications. The purpose of this study was to evaluate the effect of the SANYAR ® video laryngoscope(S-VL) on laryngeal view and first Pass Success of tracheal Intubation compared with direct laryngoscopy.

Methods: This comparative, prospective clinical study was conducted on 120 adult patients in a single-center, in a surgical ICU under the supervision of an anesthesiologist in a university hospital. Difficult airway predictors, glottic view, first Pass Success of tracheal Intubation and time of intubation were evaluated with Macintosh laryngoscopy (ML) or the SANYAR® Video Laryngoscope(S-VL).

Results: Tracheal intubation was performed in 58 critically ill patients using ML and 62 patients using S-VL. According to Cormack and Lehane (C&L) grading glottic visualization was more difficult using ML (41%, C&L grade 3 and 4) compared with S-VL (13%, C&L grade 3 and 4) p<0.001. Intubation of trachea was more successful in the first attempt, in patients with at least one difficult airway predictor with a S-VL compared to ML (87% vs. 38%; P = 0.001), time of intubation was also shorter by using S-VL.

Conclusion: Among critically ill patients in the intensive care unit, who require intubation, the SANYAR video laryngoscopy improved glottis view compared to the Macintosh direct laryngoscopy and first-pass orotracheal intubation rate especially in patients with potentially difficult airways.
