Soltesz S, et al. - This study investigated the impact of neuromuscular blockade on expiratory tidal volumes in patients with expected difficulty in mask ventilation. In all cases, an improved facemask ventilation was achieved, with a potentially clinically relevant increase in tidal volume, as a result of rocuronium administration at a dose of 0.6 mg.kg^-1. Overall, early use of a neuromuscular blocking agent can be considered as a therapeutic option in case of difficulty with mask ventilation.
