The Tritube is a narrow-bore cuffed tracheal tube (outer diameter 4.4 mm and inner diameter ~2.4 mm) that permits effective alveolar gas exchange using flow-controlled ventilation. Constant gas flow delivers physiological minute volumes, within preset pressure limits, and applies suction to the airway during expiration. ⋯ Cuff inflation protects the lower airway and produces a motionless operating field. We describe the structure of the device, discuss its benefits, and suggest how it should be used clinically.

The delivery of drugs from the manufacturer to the hospital is a complex process. Despite numerous safeguards, lapses may occur, creating the potential for patient harm. ⋯ No patients received the anesthetic. This report describes how such an error occurred, explains the differences between veterinary and human medications, and emphasizes the importance of vigilance in the drug supply chain to prevent patient harm.
