Clinical evaluation of a modified posterior anatomical approach to performing the popliteal block.
Tibial and common peroneal nerves can be blocked by the posterior approach to the popliteal fossa. Techniques using fixed measured distances between knee skin crease and puncture point have been described. We report on an approach that is based on manual identification of the apex of the popliteal fossa. ⋯ The modified posterior anatomical approach for popliteal sciatic nerve block is easy to perform, has a high success rate, and has a low complication rate. The location of the needle insertion point is assessed without any measurement, thus avoiding inaccuracies caused by repeated skin-distance measurements.

Lumbar facet nerve (medial branch) block for pain relief in facet syndrome is currently performed under fluoroscopic or computed tomography scan guidance. In this three-part study, the authors developed a new ultrasound-guided methodology, described the necessary landmarks and views, assessed ultrasound-derived distances, and tested the clinical feasibility. ⋯ Ultrasound guidance seems to be a promising new technique with clinical relevance and the potential to increase practicability while avoiding radiation in lumbar facet nerve block.

Case ReportsTransient vascular insufficiency after axillary brachial plexus block in a child.
Axillary block is used in children for procedures on the hand and forearm. We report on a child with an amputation of the thumb in whom an axillary block was given, after which the limb became pale and pulseless. The pulses returned spontaneously in 15 min. The awareness of this possibility and chances of spontaneous recovery should be considered. ⋯ Transient vascular insufficiency of the upper limb may happen as a rare complication after axillary block. Knowledge of this complication can help the anesthesiologist in the management of this problem.

Clinical Trial[Parascalene block for shoulder arthroscopic surgery].
To evaluate the effectiveness of a parascalene block of the brachial plexus as the single form of anesthesia for arthroscopic surgery on the shoulder and for postoperative analgesia. ⋯ The parascalene technique to provide a brachial plexus block is effective for arthroscopic shoulder surgery.

The anesthetic of a patient who presented for vascular access under axillary block is described. After physical examination and ultrasound study, the patient was found to have a bifid axillary artery. Because of neurologic anomalies associated with this vascular variation, an interscalene block was chosen for the procedure. The clinical implications of a bifid axillary artery when an axillary block is contemplated are discussed.
