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.

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.

Multicenter StudyFactors predicting success and failure for cervical facet radiofrequency denervation: a multi-center analysis.
The concept of radiofrequency denervation has recently come under question in light of several studies showing minimal to no benefit. One possibility proposed for these negative outcomes is poor selection criteria. Unlike virtually all other spine interventions, the factors associated with success and failure for cervical facet denervation have yet to be determined. The purpose of this study is to determine which demographic, clinical and treatment factors are associated with cervical facet radiofrequency denervation outcomes. ⋯ Selecting patients based on key clinical variables may increase the chance of treatment success for cervical facet radiofrequency denervation.
