Comparative Study
Short- and long-term effects of emergency medicine sonography on formal sonography use: a decade of experience.
It has been reported that use of formal sonographic studies by departments of radiology initially increases after inception of an emergency medicine (EM) sonography training program, but there are no data on whether this trend continues as the training program matures. The purpose of this study was to evaluate the effect of an ongoing EM sonography program on formal sonography use after more than a decade of experience. ⋯ Emergency department use of formal sonography services increases with the introduction of ED sonography but decreases markedly as the program matures.

We aimed to assess the clinical usefulness of the third ventricle midline shift (MLS) evaluated by transcranial color-coded sonography (TCCS) in acute spontaneous supratentorial intracerebral hemorrhage (ICH). ⋯ Midline shift may be measured reliably by TCCS in spontaneous supratentorial ICH. Our study also showed that MLS on TCCS is a useful and convenient method to identify patients with large ICH and hematoma expansion and to predict short-term functional outcome.

A successful brachial plexus block requires a large volume of a local anesthetic. Sonography allows reliable deposition of the anesthetic around the cords of the brachial plexus, potentially lowering the anesthetic requirement. ⋯ A successful infraclavicular block in adults with 14 mL of lidocaine is feasible with the use of sonography. The reduced volume does not seem to affect the onset but shortens the duration of the block.

The purpose of this study was to evaluate the correlation between the radiographic and ultrasonographic measurements of craniocaudal displacement of the left hemidiaphragm. ⋯ These results allow us to conclude that ultrasonography can be used as an alternative method for left hemidiaphragm mobility evaluation compared with radiography.

Randomized Controlled Trial
Is fluid ingestion really necessary during ultrasonography for detecting ureteral stones? A prospective randomized study.
Ultrasonographic evaluation of ureteral stones is usually performed after fluid ingestion for filling the bladder to visualize the ureterovesical junction better. We hypothesized that water ingestion may decrease the imaging quality of ultrasonography for detecting ureter stones. In our prospective randomized study, the accuracy of ultrasonography for detecting ureteral stones performed with or without fluid intake were evaluated. ⋯ This prospective randomized study showed that the diagnostic accuracy of ultrasonography for detection of middle ureteral stones increased significantly when performed without any water ingestion before the procedure. We recommend that patients thought to have ureteral stones should be first examined without any fluid ingestion.
