Comparative Study Observational Study
Safety of Femoral Nerve Blockade for Hip Fractures inAdult Patients Treated with Anti-Xa Direct Oral Anticoagulants: A Pilot Study.
Limited data exist regarding the safety of ultrasound-guided femoral nerve blockade (US-FNB) in patients with hip fractures treated with anti-Xa direct oral anticoagulants (DOAC). ⋯ Regarding patients treated with Anti-Xa DOAC, US-FNB was not associated with an increase in major bleeding events compared to conventional analgesia, although it was an effective means of pain alleviation. Larger scale randomized controlled trials are required to determine long-term safety and efficacy.

Randomized Controlled Trial
Comparison of the effects of corticosteroid and hyaluronic acid-carboxylmethylcellulose (HA-CMC) solution on selective nerve root block (SNRB) for lumbar radiculopathy: A prospective, double-blind, randomized controlled clinical trial.
Selective nerve root block (SNRB) was shown to effectively control radiating pain and reduce the need for surgical intervention. However, repetitive injections may trigger corticosteroid-induced side effects (hypercorticism, hyperglycemia, or fluid retention). This study aims to compare the potency of hyaluronic acid-carboxymethylcellulose (HA-CMC) solution versus that of corticosteroids regarding lower leg radiating pain (LLRP) improvement and functional outcome. ⋯ Considering the adverse effects of corticosteroids, and the similar LLRP improvements, functional outcome, and quality of life, the HA-CMC solution may be an alternative option to corticosteroid in SNRB.

The Efficacy of Intraoperative Freehand Erector Spinae Plane Block in Lumbar Spondylolisthesis: A Randomized Controlled Study.
Prospective randomized comparative (controlled) study. ⋯ Intraoperative ESPB as a part of multimodal analgesia was effective. For posterior instrumented patients with spondylolisthesis, it can relieve postoperative backache and reduce opioid consumption.Level of Evidence: 1.

Cadaveric investigation of the minimum effective volume for ultrasound-guided suprainguinal fascia iliaca block.
This cadaveric dose-finding study investigated the minimum effective volume of dye in 90% of cases (MEV90), required to stain the femoral, lateral femoral cutaneous and obturator nerves for ultrasound-guided suprainguinal fascia iliaca block (SIFIB). ⋯ For ultrasound-guided SIFIB, the MEV90 of dye required to stain the femoral, lateral femoral cutaneous and obturator nerves is 62.5 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in human subjects.
