Randomized Controlled Trial Comparative Study Clinical TrialHigh-dose bupivacaine, levobupivacaine and ropivacaine in axillary brachial plexus block.
Racemic bupivacaine is clinically similar to levobupivacaine, or ropivacaine. The drugs were compared in brachial plexus block for the first time in the same randomized and double-blind study. ⋯ Ropivacaine-HCl 5 mg ml(-1) produced slightly better sensory and motor block intensity than the same dose of levobupivacaine-HCl. General success in relation to surgery and in the duration of the blocks was similar in the three groups.

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.

Osteoarthrosis of the zygapophyseal joint (Z-joint) is a potential cause of chronic cervical pain. The diagnosis of thirty patients, with pain of more than 12 months duration and with no history of trauma, was confirmed with intra-articular fluoroscopy-guided infiltration of anesthetic. ⋯ The mean time for relapse of 50 percent of the pre-injection level of pain was 12.47 +/- 1.89 weeks, significantly longer than 3 days as reported in patients similarly treated following whiplash neck injury. At this point selective blockade of Z-joints may be offered as an adjunct for diagnostic and therapeutic purposes for patients with chronic neck pain due to facet osteoarthrosis in the ambulatory setup.
