RESUMO
In an attempt to improvise the analgesia in patients with femoral fractures, we aimed at depositing local anesthetic deep to anterior psoas fascia (APf) under ultrasound (US) guidance to block lumbar plexus elements which emerge lateral, anterior, and medial to the psoas major muscle. We termed this as circumpsoas block (CPB). Clinical and computed tomography contrast studies revealed that a continuous CPB infusion with a catheter provided a reliable block of the lumbar plexus elements. No adverse were events noted. We conclude that US guided CPB is a reliable technique for managing postoperative pain after surgery of femur fractures.

Children with Klippel-Trenaunay syndrome have vascular malformations, varicosities at unusual distribution, and unilateral soft and skeletal tissue hypertrophy of the lower extremity. Corrective surgery of the deformity is necessary to improve gait and wear acceptable footwear. Perioperative pain relief for debulking of the right great toe in a known case of KTS with sciatic hemangioma was achieved with ultrasound-guided sciatic nerve block in an avascular area.
RESUMO
Background and Aims: The outcomes of plexus and peripheral nerve blocks depend on needle-nerve contact and the spread of local anesthetic (LA) around the plexus or nerve. Needle-nerve distance and spread of LA could be visualized during US-guided lumbar plexus block (LPB). Material and Methods: After Institutional Ethics Committee approval and after obtaining informed consent, 24 American Society of Anesthesiologists'-physical status I-III patients who underwent surgical fixation of fractures of proximal femur were enrolled. Spinal anesthesia was a primary anesthetic in all patients. At the end of the surgery, all patients received US and neurostimulation-aided LPB at the third lumbar nerve root (LNr). The primary aim was to determine the spread of LA in the lumbar plexus area with the relation of the needle tip and LNr contact. The secondary aim was to understand block efficacy in terms of pain scores monitored at regular intervals and 100 mg intravenous tramadol was administered as a rescue analgesic if VAS >4. Results: In all 24 patients, we observed an oval and antegrade LA spread after lumbar plexus was identified with neurostimulation at L3. With the needle closer to intervertebral foramina (IVF), a retrograde spread was visualized. Only 2/24 patients received rescue analgesia in the first 24 h. Conclusion: The type of spread after the US-guided LPB could predict block success of block and a possible epidural spread.
