Prevention of laryngospasm with rocuronium in cats: a dose-finding study

Rocuronium 0.3 mg kg−1 and 0.6 mg kg−1 consistently decreased the completeness and duration of the laryngeal response to water spray, and reduced the number of arytenoid adductive movements in response to that stimulus. However, a laryngeal response was never completely prevented. Rocuronium 0.3 mg kg−1 may be useful for facilitating tracheal intubation. Positive pressure ventilation must be available for cats administered rocuronium.
