Pneumothoraces and chest tube placement after CT-guided transthoracic lung biopsy using a coaxial technique: incidence and risk factors.
This study investigates factors influencing the risk of pneumothorax and chest tube placement in patients undergoing CT-guided transthoracic lung biopsy for pulmonary lesions using a coaxial technique. ⋯ Lesion depth is the predominant risk factor for pneumothorax in patients undergoing CT-guided transthoracic lung biopsy. Chest tube placement is necessary more frequently in patients with severe emphysema, obstructive lung disease, or hyperinflation.

The purpose of this study was to evaluate the use and complication rate of tunneled femoral hemodialysis catheters placed in patients with no remaining thoracic venous access sites. ⋯ Femoral vein catheters require more frequent interventions than do thoracic catheters and are more susceptible to infection. However, in patients with difficult central venous access, the common femoral vein may be successfully used for permanent tunneled hemodialysis access.

Randomized Controlled Trial Clinical TrialComputerized realistic simulation: a teaching module for crisis management in radiology.
Computerized realistic simulation technology has been used as a training tool in fields such as aviation and military training and in the nuclear power industry. More recently, it has been adapted for use in anesthesia crisis resource management. We describe the effectiveness of a simulation program like that used by anesthesiology departments that we developed to teach radiologists the principles of crisis management. ⋯ Although the critical assessment of a teaching method is difficult and subjective by nature, the improvement in behavioral performance scores suggests that simulation technology effectively conveyed the principles of crisis management. The course ratings show that the program was well accepted by participants.
