Randomized Controlled Trial Clinical TrialA sonographically guided technique for central venous access.
The internal jugular vein (IJV) is an important access to the central venous system. We compared sonographically guided technique with the traditional anatomic landmark technique for IJV catheterization. ⋯ The sonographically guided technique is associated with less risk and less inconvenience for patients, especially critically ill patients, for whom the technique provides fast, safe, and easy IJV catheterization.

Clinical application of the Ottawa ankle rules for the use of radiography in acute ankle injuries: an independent site assessment.
Previous studies show that the clinical criteria known as the Ottawa ankle rules (OAR), used for determining the need for radiographs of the ankle when a fracture is suspected, have a sensitivity of 100%, a specificity of 50%, and an overall reduction in radiographs of the ankle of 28%. The purpose of this study was to further assess the clinical usefulness of the OAR when implemented in an emergency department of a level 1 trauma center. ⋯ When implemented at a level 1 trauma center, the OAR can adequately screen for ankle fractures.
