Case ReportsCombination of ultrasound-guided lumbosacral plexus block with anterior quadratus lumborum block in supine position for hip surgery: a case report.
It was widely recognized that the procedure of ultrasound-guided lumbar and sacral plexus block is required to be performed in a lateral decubitus position that patients' hips and knees were bended. It is difficult, however, for patients with hip fractures to change position because of severe pain and confined movements. We here reported a new modified combination of ultrasound-guided lumbosacral plexus block with anterior quadratus lumborum block in supine position that had been successfully applied in one elderly patient who underwent hip surgery.

Case ReportsUltrasound-guided percutaneous intercostal nerve cryoneurolysis for analgesia following traumatic rib fracture -a case series.
Rib fractures are a common injury in trauma patients and account for significant morbidity and mortality within this population. Local anesthetic-based nerve blocks have been demonstrated to provide significant pain relief and reduce complications. However, the analgesia provided by these blocks is limited to hours for single injection blocks or days for continuous infusions, while the duration of this pain often lasts weeks. ⋯ Ultrasound-guided percutaneous cryoneurolysis is a modality that has the potential to provide analgesia matching the duration of pain following rib fractures.

Randomized Controlled Trial
Ultrasound-guided erector spinae block versus mid-transverse process to pleura block for postoperative analgesia in lumbar spinal surgery.
In recent years, promising results were achieved with the use of ultrasound (US)-guided interfascial plane blocks for effective postoperative analgesia in several surgeries. Erector spina plane (ESP) block and mid-transverse to pleura plane (MTP) block are the latest techniques in this area. The aim of this prospective and randomized study was to compare the postoperative analgesic efficacy of bilateral ESP and MTP blocks in patients undergoing lumbar spinal surgery under general anesthesia (GA). ⋯ Both ESP and MTP blocks provided effective pain relief after lumbar spinal surgery but the ESP block was superior to MTP block regarding postoperative analgesia in the first 24 h.

Real-time continuous monitoring of injection pressure during peripheral nerve blocks in fresh cadavers.
The incidence of unintentional intraneural injection while performing peripheral nerve block has been estimated to be 15% under real-time ultrasound guidance. Injection pressure increase may detect an intraneural injection. Real-time injection pressure changes throughout an entire nerve block procedure in relationship with needle tip location have never been reported. ⋯ Based on significant differences in injection pressure values and curve shapes, the system was able to discriminate between four needle tip locations. This may help with needle tracking while performing a peripheral nerve block.
