Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomized, double-blinded comparison of ropivacaine 0.5%, 0.75%, and 1% ropivacaine for peribulbar block.
To evaluate the efficacy of three different concentrations of ropivacaine (0.5%, 0.75%, and 1%) together with a single concentration of hyaluronidase administered for peribulbar block. ⋯ While confirming that ropivacaine is a good option for peribulbar anesthesia, this study demonstrated that the use of 0.75% or 1% concentrations are preferred in that they produce quick and deep sensory and motor block of the operated eye. If recovery of normal motor function is important after surgery, the 0.75% concentration probably represents the best compromise.

ReviewSelective nerve root blocks for low back pain and radiculopathy.
In the management of patients with low back pain and radiculopathy, selective nerve root blocks (SNRBs) are now a common procedure for both diagnostic and therapeutic purposes. This article reviews the available studies as well as the relevant anatomy, pathology, technical considerations, and complications.

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.

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.

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.
