This study defines the spatial relationship of the diagnostic planes of the fetal heart to the 4-chamber view plane in the second trimester of pregnancy as a first step in the automation process. ⋯ This study shows the spatial relationship of fetal cardiac diagnostic planes to the 4-chamber view plane in the second trimester of pregnancy in 3-dimensional volumes. Testing the clinical applicability of automated software based on these formulas is the next step.

To optimize forearm radiocephalic fistula success, many programs recommend a minimal cephalic vein diameter of 0.25 cm or greater on preoperative sonographic mapping. It is not established, however, whether a vein diameter before or after application of a tourniquet should be used in determining suitability for creation of a forearm fistula. ⋯ The use of a venous tourniquet increases the number of patients eligible for forearm fistulas without decreasing the adequacy rate of these fistulas. Therefore, a tourniquet should routinely be used in patients with small cephalic veins on pretourniquet evaluation.

The aim of this study was to analyze our experience in 1146 cases of sonographically guided infraclavicular brachial plexus block (ICBPB) performed over 32 months. ⋯ The data from this retrospective study suggest that sonographic guidance provides a high success rate (99.3%) and improved safety for ICBPB. The increased operator team experience virtually eliminates failure and complications.

The aim of this study was to describe a sonographically guided ilioinguinal nerve block in adults. ⋯ This technique is reliable and reproducible. The block is achievable by a low-volume local anesthetic injection. Visualization of the intestines and blood vessels in the abdominal wall may help prevent an inadvertent injury.

Comparative Study
Diagnostic values of sonography for assessment of sternal fractures compared with conventional radiography and bone scans.
This study was prospectively undertaken to evaluate the diagnostic value of sonography for detection of sternal fractures. We compared sonographic, conventional radiographic, and bone scan examinations of sternal fractures. ⋯ We could detect sternal fractures more effectively with sonography than with conventional radiography and bone scans. In addition, sternal fracture locations showed relatively even distributions, and focal fractures in the manubrium were not easily detected on bone scans.
