Ultrasound-Guided Approach for L5 Dorsal Ramus Block and Fluoroscopic Evaluation in Unpreselected Cadavers.
Medial branch blocks are frequently performed to diagnose lumbar facet-joint-mediated pain. Ultrasound guidance can increase practicability and eliminate exposure to ionizing radiation when compared with fluoroscopy. However, ultrasound-guided L5 dorsal ramus block, which, together with L4 medial branch block is necessary to anesthetize the most commonly affected facet joint L5/S1, has not been described so far. The objective of this study was to develop a technique and to evaluate its accuracy with standard fluoroscopy in unpreselected cadavers. ⋯ This is the first study to show that ultrasound-guided L5 dorsal ramus block is accurate and feasible in the absence of significant spondylolisthesis when performed with an oblique out-of-plane technique.

Case ReportsUnilateral Transversus Abdominis Plane Block Catheter for the Treatment of Abdominal Wall Pain in Pregnancy: A Case Report.
The transversus abdominis plane (TAP) block anesthetizes the anterior branches of spinal nerves that innervate the abdominal wall from T6 to L1 dermatomes and provide effective postoperative analgesia after abdominal surgery. Several applications of TAP catheters are described for both acute and chronic abdominal wall pain, but there are no reported cases of TAP catheters used during pregnancy. ⋯ A TAP catheter inserted under ultrasound guidance can be effective for the treatment of chronic abdominal pain during pregnancy and may provide an alternative analgesic modality when intravenous opioids are not providing relief or when neuraxial analgesia techniques are not feasible or contraindicated.
