Case Reports
Spinal epidural hematoma following central neuraxial blockade and subcutaneous enoxaparin: a case report.
An elderly patient developed a spinal epidural hematoma 3 days after lumbar puncture resulting in paraplegia. Concurrent administration of enoxaparin, aspirin, ketorolac, and a traumatic tap were implicated in causation.

Randomized Controlled Trial Clinical TrialInjection pain and postinjection pain of the anterior middle superior alveolar injection administered with the Wand or conventional syringe.
The purpose of this prospective, randomized, blinded study was to compare the pain of injection and post-injection pain of the AMSA injection using the computer-assisted Wand Plus injection system versus a conventional syringe. ⋯ The AMSA injection, using the Wand Plus, resulted in similar pain ratings for needle insertion as the conventional syringe but statistically lower pain ratings upon anesthetic solution deposition. However, the AMSA, using either the Wand Plus or a conventional syringe, has the potential to be a painful injection. We found the incidence of postinjection pain and sequelae was low with both techniques.

Ultrasound guidance for infraclavicular brachial plexus anaesthesia in children.
Ultrasonography may offer significant advantages in regional anaesthesia of the upper and lower limbs. It is not known if the same advantages demonstrated in adults also apply to children. We therefore performed a prospective, randomised study comparing ultrasound visualisation to conventional nerve stimulation for infraclavicular brachial plexus anasesthesia in children. ⋯ Direct ultrasound visualisation was successful in all cases and was associated with significant improvements when compared with the use of nerve stimulation: lower visual analogue scores during puncture (p = 0.03), shorter mean (median) sensory onset times (9 (5-15) min vs. 15 (5-25) min, p < 0.001), longer sensory block durations (384 (280-480) min vs. 310 (210-420) min, p < 0.001), and better sensory and motor block scores 10 min after block insertion. Ultrasound visualisation offers faster sensory and motor responses and a longer duration of sensory blockade than nerve stimulation in children undergoing infraclavicular brachial plexus blocks. In addition, the pain associated with nerve stimulation due to muscle contractions at the time of insertion is eliminated.
