Intrapulmonary percussive ventilation via Mini-Trach II in critical care: a case report

Abstract

Abstract Background Intrapulmonary percussive ventilation (IPV) facilitates the mobilization and clearance of bronchial secretions. Cricothyroidotomy using a Mini-Trach II device is a minimally invasive method used for secretion clearance. To our knowledge, there are no previous reports regarding IPV combined with Mini-Trach II. Case presentation An 82-year-old man underwent controlled mechanical ventilation and IPV via an endotracheal tube to treat atelectasis following emergency surgical repair of a traumatic diaphragm laceration. He underwent cricothyroidotomy using Mini-Trach II for ensuring airway management after extubation. On resumption, IPV through a mouthpiece or face mask was unsuccessful owing to air leakage from his mouth. However, IPV via the already inserted Mini-Trach II could deliver the percussion flow and led to a marked improvement in his condition. Conclusion This experience indicates that Mini-Trach II is beneficial as a minimally invasive interface for IPV that can deliver percussion flow efficiently.
