The objective of this study was to describe the suprascapular nerve block using CT guidance and to evaluate the short- and medium-term efficacy in a range of shoulder pathologies. ⋯ In some patients with chronic soft tissue pathologies who do not respond to conventional treatment, a CT-guided suprascapular nerve block can provide safe short- and medium-term relief from pain and disability.

Review[Analgesia, sedation and neuromuscular block in pediatric intensive care units: present procedures and recent progress].
Anxiolysis and pain control are a duty for physicians and must be treated very carefully in the Pediatric Intensive Care Units, although it is very difficult to assess them: in critically ill children sedatives and/or analgesic medications are routinely provided and titrated to obtain a satisfactory level of sedation, but different evaluation scores are needed to discriminate between light or inadequate and deep or excessive sedation, especially when the clinical examination is unavailable. It is usual to associate a benzodiazepin with an opioid, more often Midazolam and Morphine or Fentanyl; other drugs as Propofol, Clonidine and Ketamine have specific indications, brief painful procedures and weaning from long periods of sedation to avoid withdrawal. Sometimes it can be useful to add a neuromuscular blocking agent to help mechanical ventilation. Adverse sedation events are relatively frequent, associated with drug overdoses and drug interactions, particularly when 3 or more drugs are used: all class of medications and all routes of administration are involved.

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.
