BACKGROUND: Videolaryngoscopy has been proposed to improve glottic visualization and intubation success during rapid sequence intubation (RSI). Evidence on the effectiveness of the McGrath videolaryngoscope in this setting remains limited.
METHODS: In this multicenter, patient-blinded, randomized trial, 400 adults undergoing elective non-cardiac surgery requiring RSI were assigned to McGrath videolaryngoscopy (VL, n = 193) or direct laryngoscopy (DL, n = 201). The primary outcome was glottic visualization using the modified Cormack-Lehane (CL) classification. Secondary outcomes included first-attempt intubation success, number of attempts, intubation failure, and time to intubation. Safety outcomes included airway injury and postoperative complications.
RESULTS: Glottic visualization did not differ significantly between groups (Grade 1 view: VL 46.6% vs DL 42.3%; OR 1.24, 95% CI 0.85-1.79; P = 0.26). First-attempt success was similar (VL 86.5% vs DL 87.6%; P = 0.76). Intubation failure occurred in 1.6% of VL and 0.5% of DL cases (P = 0.29). Median time to intubation was longer with VL (35 s vs 30 s; HR 1.27; 95% CI 1.04-1.56; P = 0.016). Rates of airway trauma and postoperative complications were low and comparable.
CONCLUSIONS: In adult patients undergoing RSI, McGrath videolaryngoscopy did not improve glottic visualization or first-pass intubation success compared with direct laryngoscopy, and was associated with a modestly longer intubation time. Adverse events were infrequent and similar. These findings suggest that the routine use of McGrath for RSI may not confer clinical benefit in low-risk elective surgical populations.
