Comparative Study Controlled Clinical Trial
[Interscalene block for total shoulder arthroplasty: comparative study (ultrasound vs. neurostimulation)].
Modern anesthesiology has integrated the use of ultrasonography as a tool that has displaced neurostimulation as a technique for locating peripheral nerves. The aim of this study was to determine which procedure is more effective for guiding interscalene block for total shoulder arthroplasty. ⋯ Ultrasound-guided interscalene nerve block is the technique of choice in elective total shoulder arthroplasty.

Comparative Study
[Preoperative embolization with microspheres of giant supratentorial meningiomas: 5-year experience].
Preoperative embolization of hypervascular tumours such as meningiomas has proven to be a favorable factor for resection of the latter because it diminishes intraoperative bleeding and the need for blood transfusions. ⋯ Embolization with microspheres improves resection rate evaluated by the Simpson scale in patients with giant supratentorial meningiomas.
