An intertransverse process block (ITPB) is a paraspinal thoracic nerve block technique, where the local anesthetic (LA) is injected into the thoracic intertransverse tissue complex posterior to the superior costotransverse ligament (SCTL). Although an ITPB can be ultrasound-guided, it is performed using surrogate bony landmarks without even identifying the SCTL. This report describes a transverse ultrasound imaging technique to identify the retro-SCTL space and perform an ITPB with a retro-SCTL space injection, in 2 patients undergoing video-assisted thoracoscopic surgery. The resultant bilateral, symmetrical, thoracolumbar anesthesia was consistent with epidural spread of the LA and effective for perioperative analgesia.

Ultrasound-guided (ULSD-g) genicular nerve blocks (GNB) using pharmacological agents for pain control in chronic knee osteoarthritis (OA) are gaining in popularity. There lacks a systematic review to evaluate the ULSD techniques and pharmacological agents used during the intervention, and to assess the knee's function postintervention. ⋯ There is fair evidence to at least target the superior medial genicular nerve, inferior medial genicular nerve, and Inferior medial genicular nerve using local anesthetics, corticosteroids, or alcohol to reduce pain and to improve knee function in patients with chronic knee OA under ULSD guidance. The procedure is safe but more research is needed to determine the optimal interventional approach.

Caudal and dorsal penile nerve blocks are commonly used regional anesthesia methods in hypospadias surgery. Some studies have reported that regional anesthesia methods are risk factor for the development of postoperative complications following hypospadias surgery. The aim of the current study is to evaluate the relationship between postoperative complications and regional anesthesia methods used in distal hypospadias surgery. ⋯ Conflicting data are found in the literature on the long-term postoperative complications of the regional anesthesia techniques used in hypospadias surgery. In our study, all patients with urethrocutaneous fistula were in the caudal block group. We believe that our study will contribute to the literature as it is the only study comparing caudal block with US-guided dorsal penile nerve block using in-plane technique in terms of postoperative complications in hypospadias surgery.

Shoulder dislocations are a common presenting injury to the emergency department (ED), with anterior dislocations comprising the majority of these cases. Some patients may tolerate gentle manipulation and reduction, but many require analgesia of some type. Oral or parenteral pain medication is often used alone or in combination with procedural sedation if gentle manipulation fails to achieve reduction. Recently, this treatment algorithm has grown to include regional anesthesia as a mode of analgesia for reduction of shoulder dislocations in the form of brachial plexus blocks. It has been well described that the interscalene and supraclavicular approach to the brachial plexus can be used to assist in reduction of anterior shoulder dislocations; however, there has yet to be any published literature regarding the use of ultrasound-guided retroclavicular approach to the infraclavicular region (RAPTIR) brachial plexus blocks for shoulder reduction. ⋯ We describe three patients who presented to the ED with anterior shoulder dislocations. The RAPTIR block was performed, provided effective analgesia, and facilitated successful shoulder reduction in all three patients.Why Should an Emergency Physician Be Aware of This? The RAPTIR nerve block is a safe and effective option for analgesia in the patient with an anterior shoulder dislocation. It may have advantages over other brachial nerve blocks and avoids the risks and disadvantages of procedural sedation and opioids.
