Injection pressure monitoring during peripheral nerve blocks: from bench to operating theatre.
Nerve damage can occur after ultrasound-guided peripheral nerve block (PNB). Injection pressure monitoring could improve the safety of PNB. The aim was to analyse parameters affecting pressure measurements during PNB. ⋯ Needle diameter, needle tip location, type of nerve/plexus, flow rates, and the anaesthetist can have a significant effect on injection pressure values and monitoring.

Comparison of regional analgesia techniques for pleurodesis pain in pediatric patients.
Mechanical pleurodesis can prevent recurrence of spontaneous pneumothorax but is associated with significant postoperative pain. Adequate pain control is not only beneficial for patient comfort but also critical for mobilization and pulmonary recovery. Thoracic epidural catheters and paravertebral blocks have been used to alleviate pain after thoracoscopic surgery. However, no studies have evaluated the safety and efficacy of paravertebral block vs epidural analgesia vs no block in children undergoing pleurodesis. ⋯ Thoracic epidural analgesia offers a reduction in opioid use in the first two post-op days after pleurodesis but did not produce a clinically significant reduction in pain scores in comparison with paravertebral block or no block.

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.
