Initial evaluation of a new optic laryngoscope blade.

We report on a new optic laryngoscope blade that provides two views of the larynx during tracheal intubation. The availability of an alternative direct view of the larynx may improve the ability of anesthesia providers to observe the tracheal tube passing through the vocal cords when using a Macintosh laryngoscope blade. The optic port improved visualization of passage of the endotracheal tube in obese patients.

Rapacuronium and the risk of bronchospasm in pediatric patients.

Unlabelled: We conducted this study to determine the risk factors for the development of bronchospasm after the administration of rapacuronium and to determine if children with bronchospasm on induction of anesthesia were more likely to have received rapacuronium compared with other muscle relaxants. In a retrospective cohort study, all anesthetic records in which rapacuronium was administered were reviewed to determine which patients developed bronchospasm during induction of anesthesia. Two-hundred-eighty-seven patients were identified, of whom 12 (4.
