Right-sided double-lumen tubes (DLTs) have a bad reputation. Many experts in the field of thoracic anesthesia regard them as being difficult to position, having a small margin of safety for correct placement, and being prone to intraoperative malpositioning. However, in a randomized prospective study, Campos et al. compared the use of right vs left DLTs in two groups of 20 patients having left ...

The isolation and quantitation of the surface-active phospholipids of the lipids extracted from mammalian saline lung extracts were studied by the direct application of thin-layer chromatography. The significant recovery of 85% of the phospholipids suggests that the method described can be used for the quantitative analysis of the surface-active material of lung extract and for further compleme...

Presence and frequency of rare circulating tumor cells (CTCs) in bloodstreams of cancer patients are pivotal to early cancer detection and treatment monitoring. Here, we use a spiral microchannel with inherent centrifugal forces for continuous, size-based separation of CTCs from blood (Dean Flow Fractionation (DFF)) which facilitates easy coupling with conventional downstream biological assays....

A survey of laboratory records was made to assess the value of the precipitin test and isolation methods in the diagnosis of farmer's lung disease and also to determine its prevalence in the farming population of Somerset. A link was established between the clinical diagnosis as written on the form that accompanied the specimen and the actual number of positive laboratory diagnoses made. Fifty ...

Resecting and reconstructing the carina is an anesthetic challenge in the best of circumstances. The surgery is meticulous and requires access to the trachea and bronchi, ruling out traditional lung isolation techniques. When resection of the carina is due to traumatic disruption, confounding thoracic injuries can make adequate ventilation and oxygenation difficult, especially when only one lun...
