Validity of CT classification on management of occult pneumothorax: a prospective study.
In the setting of blunt trauma, abdominal CT, which routinely includes images of the lower thorax, frequently reveals pneumothoraces that have not been detected on routine supine chest radiographs. Proper management of these occult pneumothoraces remains controversial. The purpose of this study was to test the hypothesis that small (minuscule) to moderate (anterior) radiographically occult pneumothoraces can be safely managed without chest tube placement for patients in whom the need for positive pressure ventilation is not anticipated. ⋯ Most small (minuscule) occult pneumothoraces can successfully be managed with close observation. The risk that the pneumothorax will progress is slight. Moderate-sized (anterior) pneumothoraces may also be successfully managed without initial placement of a chest tube if the patient is not to undergo positive pressure ventilation.

Sonographic guidance when using the right internal jugular vein for central vein access.
The intent of this study was to substantiate the advantages of the use of sonographic guidance for central venous access via the right internal jugular vein. ⋯ Sonographic guidance for central vein access via the right internal jugular vein is safer and more efficient than the traditional landmark approach.
