BACKGROUND A voice tracheostomy tube (VTT) was developed to enable patients to speak during mechanical ventilation. METHODS The VTT has slits cut in it and is covered on part of its side with an elastic cuff, enabling the cuff to expand with positive pressure from the ventilator on inspiration and to deflate on expiration. By this mechanism, inspired air from the ventilator goes to the lung w...

Sir,—Intermittent jets of oxygen may be used to ventilate patients undergoing microlaryngoscopy with a Venturi injector or by flushing oxygen directly through a small-bore endotracheal tube as we have used in 10 adult patients (table I). The patients were premedicated with pethidine 75 mg and atropine 0.6 mg and anaesthesia was induced with propanidid 250-500 mg followed by suxamethonium 100 mg...

BACKGROUND AND OBJECTIVES Patients who need to stay under endotracheal intubation for long periods or when undergoing general anesthesia may develop tracheal lumen injuries due to pressure from distal cuff. In some cases, these injuries may evolve to stenosis or, occasionally, necrosis. The objective of this study was to present a modified endotracheal tube (METT) in which the cuff pressure is ...

BACKGROUND Prolonged chest tube duration is less well studied in patients who are supported by mechanical ventilation and have acquired pneumothorax. We investigated the impact of prolonged chest tube duration on patient outcomes and the risk factors associated with prolonged chest tube duration. METHODS This retrospective observational study included 106 ventilated subjects who had been trea...

BACKGROUND/AIMS Complete endotracheal tube obstruction is a medical emergency, and partial occlusion causes increased breathing rates and failure to wean off mechanical ventilation. Partial occlusion may be underestimated due to the lack of proper detection methods. We tested whether the sound of an endotracheal tube could be used to detect an endotracheal tube obstruction using an in vitro mod...

In the absence of a healthcare budget enabling the import of ready-made aural grommets, Myanmar ENT surgeons have devised an ingenious 'home-grown' solution. We describe how grommets are made from raw materials bought from the local market.

OBJECTIVE To assess cardiorespiratory variables during weaning from mechanical ventilation by using the T-tube and pressure support techniques, and to compare them in groups of patients with and without heart disease. METHODS To assess the following parameters of 20 patients (57 +/- 15 years) undergoing weaning from mechanical ventilation: oxygenation; CO2 elimination; respiratory and heart r...

Background: Postoperative pulmonary complications (PPC) are of the major reasons for death. Prolonged mechanical ventilation (PMV) and delayed extubation are leading to the incidence of more seriously complications. The effect of hyperinflation has not been investigated in control of these complications in patients who have been weaned from mechanical ventilation and are undergoing T-tube suppo...

appropriate bronchus of each child during fiberscopic vision (Olympus LF-P, 2.2-mm OD, or LF-DP, 3.1-mm OD, passed through the inner tube; Olympus Optical Co., Ltd., Tokyo, Japan). Sufficient ventilation Tohoku University Postgraduate Medical School through the inner tube was obtained during the blocker positioning using a rubber-sealed Y connector (Bodai Swivel Y; Sotek Medical Inc., Hingham)....
