We hypothesized that combined McCoy-balloon laryngoscopy may facilitate airway management relative to McCoy or balloon laryngoscopy. In 10 anesthetized/paralyzed patients with prior intubation difficulty scale scores of >5, McCoy-balloon laryngoscopy versus conventional/balloon/McCoy laryngoscopies resulted in greater laryngeal aperture exposure (2.3 ± 0.6 versus 0.6 ± 0.2/1.4 ± 0.4/1.5 ± 0.6 cm2, respectively), lower intubation difficulty scale score (0.00 (0.00–0.00) versus 6.00 (6.00–8.25)/1.50(0.00–4.00)/2.00(0.75–5.00), respectively, median [interquartile range]), and 9%–74% shorter time to intubation confirmation (P < 0.05–0.001 for all). Balloon and McCoy laryngoscopies improved laryngoscopic/intubating conditions relative to conventional laryngoscopy. In patients with moderate-to-major conventional airway management difficulty, McCoy-balloon laryngoscopy further improves laryngoscopic/intubating conditions.
