Ultrasound imaging used to facilitate performance of a femoral nerve block also affords imaging of adjacent anatomical structures. Following a fracture of the femur, an ultrasound guided femoral nerve block (UGFNB) was performed to provide analgesia; this led to the incidental finding of a previously undiagnosed femoral vein thrombosis (DVT), resulting in a change in patient management before surgery. An inferior vena cava (IVC) filter was placed before intramedullary nailing of the fracture.

The timing of interscalene block in relation to general anaesthesia remains a controversial subject. We believe that the results of our study demonstrate that this block may be performed safely on anaesthetized patients, providing that certain conditions are met. ⋯ It is our opinion that the primary factor for safe interscalene block is modification of the anaesthetic technique rather than the timing of regional block in relation to induction of general anaesthesia.

Case ReportsContinuous lateral popliteal block with stimulating catheters.
Foot surgery often induces severe postoperative pain. Sciatic nerve block is a good alternative for its treatment. ⋯ Stimulating catheters may be useful to verify correct catheter tip positioning. This technique seem to be easy to use and provided excellent pain relief.

In the treatment of trigeminal neuralgia, Gasserian block under fluoroscopical guidance may be difficult because of anatomic variability, and difficulty in identification of the foramen ovale. We introduce how to use three-dimensional CT in the preprocedural planning. We determine the skull-rotation angle in which the foramen ovale is best visualized, the relationship (distance, angle) between the virtual puncture point and anatomical landmarks, and the distance between the virtual puncture point and the foramen.
