BACKGROUND: Percutaneous dilational tracheostomy is normally a bronchoscope-guided procedure. The insertion of a bronchoscope into an endotracheal tube (ETT) affects resistance, flow, and alveolar pressure. To improve airway management and ventilation during percutaneous tracheostomy, we developed a double lumen endotracheal tube (DLET). The aim of this in vitro study was to compare the linear ...

Carbon nanotubes hold vast potential for device innovations because their optical and electronic properties can be synthetically tailored at a length scale unattainable by lithographic techniques. However, lithographic patterning of carbon nanotubes with electronic-type control remains one of the major problems for the integration of these nanomaterials for practical device applications. In thi...

BACKGROUND One lung ventilation (OLV) is a technique routinely used in thoracic anesthesia to facilitate thoracic surgery. Double-lumen tubes (DLT) remain the most popular and reliable choice for one lung ventilation especially in adult patients though use in Nigeria is limited. This study aimed to describe the experience in our institution with the use of double-lumen tubes for one lung ventil...

Pulmonary alveolar proteinosis is a rare disorder with decreased clearance of surfactant from the pulmonary alveoli resulting in progressive respiratory distress. Whole-lung lavage remains an important procedure for symptomatic relief in patients with pulmonary alveolar proteinosis. If a double-lumen tube can be placed, lavage of one side of the lung is performed through one lumen while the pat...
