BACKGROUND AND OBJECTIVES Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. METHODS This study involved 16 dogs submitted to...

minimize the risk of barotrauma, the following precautions are recommended. multiple distal side holes also may decrease the pressure delivered at the distal end, minimize the catheter whip, and center the catheter within the trachea during jet ventilation.3 1. The patient must be adequately preoxygenated and hyperventilated by the original endotracheal tube using 100% oxygen. 2. An exchange ca...

OBJECTIVES To review perioperative airway management and ventilation strategy during the surgical removal of papilloma under suspension laryngoscopy in pediatric patients with severe airway obstruction. METHODS Seventy pediatric patients with degree III and IV laryngeal obstruction who underwent suspension laryngoscopy to remove laryngeal papillomatosis, between July 2005 and March 2009, were...

OBJECTIVE To describe our experience in managing patients with Duchenne muscular dystrophy. PATIENTS AND METHODS We analyzed the following variables in a group of 27 patients with Duchenne muscular dystrophy: arterial blood gases, lung function before and after mechanical ventilation, oxygen saturation (measured by pulse oximetry), nocturnal PaCO2 (measured transcutaneously by capnography), h...

6 In the previous issue of Annals, a single‐center unblinded study assessing the outcomes of noninvasive bilevel positive airway pressure ventilation versus typical positive pressure ventilation through an endotracheal tube for patients with respiratory failure following initial extubation after open heart surgery provides an important reminder that traditional care requires continuous question...

PURPOSE Evaluate oxygen jet ventilation in a patient with tracheal stenosis undergoing stent insertion. CLINICAL FEATURES Manual intermittent low frequency oxygen jet ventilation was used during general anesthesia for fibreoptic bronchoscopy and stent insertion in a patient with tracheal stenosis. Oxygen jets were delivered via a Sander's injector adapted to the proximal end of the endotrache...

BACKGROUND The Portex Soft Seal high-volume, low-pressure cuffed tracheal tube was compared with the Mallinckrodt HiLo, Sheridan Preformed and Portex Profile tracheal tubes for leakage of dye placed in the subglottic space of a pig's trachea which was used in a benchtop mechanical ventilation model and in six isolated pig tracheas. RESULTS There was no leakage, either in the ventilation model...
