Randomized Controlled Trial Comparative StudyPostoperative epidural analgesia after total knee arthroplasty with sufentanil 1 microg/ml combined with ropivacaine 0.2%, ropivacaine 0.125%, or levobupivacaine 0.125%: a randomized, double-blind comparison.
Total knee replacement is associated with severe postoperative pain that, if treated insufficiently, interferes with early rehabilitation. The purpose of the present study is to compare the efficacy of ropivacaine (0.2% and 0.125%) and levobupivacaine (0.125%), all in combination with sufentanil 1 microg/mL with regard to postoperative pain relief and absence of motor block in a patient-controlled epidural analgesia setting. ⋯ All 3 solutions provided adequate analgesia and minimal motor block. The higher concentration of ropivacaine 0.2% was associated with a higher consumption of local anesthetic and did not result in a decrease in the consumption of sufentanil. Under the conditions of this study, patient-controlled epidural analgesia consumption of the epidural mixture was predominantly determined by sufentanil.

Posterior lumbar plexus block in children: a new anatomical landmark.
Posterior lumbar plexus block is a well established anesthetic technique for lower limb surgeries. Both magnetic resonance imaging and clinical prospective studies were performed to verify if a new palpable landmark could be used for lumbar plexus block in pediatric patients. ⋯ The sulcus formed by the division between the longissimus and the iliocostal muscles is a simple, direct, and easy-to-identify landmark for posterior lumbar plexus block in children.

Case ReportsBee stings--a remedy for postherpetic neuralgia? A case report.
This case report describes the effects of bee stings on painful postherpetic neuralgia in a 51-year-old man. ⋯ Bee venom and bee sting therapy have been shown to have both antinociceptive and anti-inflammatory properties, which may explain why the bee stings relieved the patient's postherpetic neuralgia. Bee sting or bee venom therapy should be further investigated as a potential treatment modality for postherpetic neuralgia.

In neuraxial anesthesia, increase of skin temperature is an early sign of successful block. Yet, during peripheral nerve block of the lower extremity, increase in skin temperature is a highly sensitive, but late sign of a successful block. We hypothesized that after interscalene brachial plexus block, a rise in skin temperature follows impairment of sensation during successful nerve block and occurs only distally, as observed in the lower extremity. ⋯ Assessment of skin temperature cannot predict the success of an interscalene brachial plexus block of the axillary and musculocutaneous nerve. Distally, the increase of skin temperature has a high sensitivity and specificity but occurs later than the loss of sensory and motor functions. Therefore, the measurement of skin temperature during interscalene blockade is of limited clinical value.

Case ReportsThree-dimensional, multiplanar, ultrasound-guided, radial nerve block.
We describe the use of 3-dimensional, multiplanar ultrasound imaging for peripheral nerve block. ⋯ Three-dimensional, multiplanar ultrasound in real-time has the potential to improve nerve identification and accuracy of needle placement in regional anesthesia.
