We report a modified block technique aimed at obtaining upper midline and lateral abdominal wall analgesia: the external oblique intercostal (EOI) block. ⋯ We demonstrate the potential mechanism of this technique with a cadaveric study that shows consistent staining of both lateral and anterior branches of intercostal nerves T7-T10. Patients who received this block exhibited consistent dermatomal sensory blockade of T6-T10 at the anterior axillary line and T6-T9 at the midline. This block can be used in multiple clinical settings for upper abdominal wall analgesia.

Randomized Controlled Trial Comparative Study Observational Study
The use of perineural dexamethasone and transverse abdominal plane block for postoperative analgesia in cesarean section operations under spinal anesthesia: an observational study.
During transverses abdominal plane block (TAP) procedure to provide analgesia in cesarean section (CS) operation, the use of perineural dexamethasone as an additive agent may improve pain relief and may cause a prolonged block duration. This study aims to investigate whether perineural dexamethasone, when added to bupivacaine local anesthetic agent during a TAP block, may provide adequate pain relief without adverse events. ⋯ An additive agent of perineural dexamethasone at a dose of 8 mg during bilateral TAP block for elective CS operation under spinal anesthesia provided better pain relief on postoperative day 1.

Case Reports
Expanded Perineal Coverage With Combined Pudendal and Inferior Cluneal Nerve Blocks: A Case Report.
The pudendal nerve (PN) block is an effective regional technique for providing analgesia to the perineum. However, when the surgical site involves dermatomal areas lateral to the PN dermatome, additional blocks are necessitated. ⋯ Analgesia was achieved using a combined PN and inferior cluneal nerve block. To our knowledge, this is the first report of this combined technique used for perioperative analgesia.
