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.

Modified lateral block of the suprascapular nerve: a safe approach and how much to inject? A morphological study.
This paper presents an evaluation of a modified lateral suprascapular nerve block with easy orientation, low risk of displacement of the needle, and with an assessment of 2 different volumes to propose an ideal volume for a successful block. ⋯ Based on this cadaver study, the lateral modified approach appears to be a safe technique for a suprascapular nerve block, which might be preferred as a single shot technique. A 5 mL volume appears sufficient to fill the supraspinous fossa and to reach the suprascapular nerve, which branches in this anatomical compartment.

Randomized Controlled TrialEffect of lumbar flexion on the extent of epidural blockade.
This study examined the effect of lumbar flexion on the extent of the epidural block during lumbar epidural anesthesia. ⋯ Lumbar flexion has no clinically relevant effect on sensory spread during epidural anesthesia.
