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.

Background Upper-extremity injuries are frequently seen in the emergency department (ED), yet traditional analgesic methods are often ineffective (e.g., hematoma blocks) or associated with prolonged ED duration and nontrivial risk (e.g., procedural sedation). Ultrasound-guided regional anesthesia of the infraclavicular brachial plexus offers dense anesthesia of the distal upper extremity. The Retroclavicular Approach to The Infraclavicular Region (RAPTIR) is an ultrasound-guided brachial plexus block that has only recently been described in both anesthesia and emergency literature. Case Report We report use of the RAPTIR block in an elderly patient with a subacute angulated distal radius fracture that would otherwise require surgical management. The patient presented 11 days post injury and had no hematoma to block, and her age made her high risk for procedural sedation or operative management. Using the RAPTIR block, ED providers achieved dense anesthesia of her arm, allowing for appropriate reduction of a displaced fracture 11 days after injury. The patient followed with orthopedic surgery, never required additional manipulation, and had full return to activities of daily living. Why Should an Emergency Physician Be Aware of This? In this case, the RAPTIR block safely and effectively anesthetized the distal upper extremity. This block provides clear visualization of neck and thoracic structures and has a simpler technique than traditional inferior brachial plexus blocks. It achieves dense anesthesia to allow for complex or repeat reduction attempts without the need for procedural sedation, opiates, or an operative setting. Our report details this patient, the RAPTIR technique, and the state of the current literature.

Single injection, ultrasound-guided nerve blocks have drastically changed the multimodal approach to pain management of the acutely injured patient in the emergency department (ED). Ultrasound-guided femoral nerve blocks in the ED have become standard aspects of multiple, hospital system pain management protocols, with early evidence demonstrating improved patient outcomes. Developing a multimodal pain management strategy can improve analgesia while reducing reliance on opioids in this era of opioid addiction.1 The single injection, ultrasound-guided erector spinae plane (ESP) block is a technique safely used for pain control for rib fractures that can be easily performed at the bedside and integrated into optimal emergency care. A more inferiorly located ultrasound-guided ESP block has been recently described in the anesthesia literature for perioperative pain control for various abdominal surgeries but has not yet been described for patients with acute appendicitis. Here we describe a single injection, lower ESP block performed by emergency physicians that successfully alleviated pain from acute appendicitis in an ED patient awaiting definitive surgical treatment. Along with allowing clinicians to actively manage pain without reliance on opioids, this novel ED technique may improve patient care outcomes.

The America Society of Anesthesiology guidelines recommend multimodal analgesia that combines regional anesthetic techniques with pharmacotherapy to improve peri-procedural pain management and reduce opioid related complications. Commonly performed emergency procedures of the upper extremity such as fracture and dislocation reduction, wound debridement, and abscess incision and drainage are ideal candidates for ultrasound-guided (USG) regional anesthesia of the brachial plexus. However, adoption of regional anesthesia by emergency practitioners has been limited by concerns for potential complications and perceived technical difficulty. The Retroclavicular Approach to The Infraclavicular Region (RAPTIR) is a newly described USG brachial plexus block technique that optimizes sonographic needle visualization as a means of making regional anesthesia of the upper extremity safer and easier to perform. With RAPTIR a single well-visualized injection distant from key anatomic neck and thorax structures provides extensive upper extremity anesthesia, likely reducing the risk of complications such as diaphragm paralysis, central block, nerve injury, vascular puncture, and pneumothorax. Additionally, patient positioning for RAPTIR is well suited for the awake, acutely injured ED patient as the upper extremity remains adducted in a position of comfort at the patient's side. Thus, RAPTIR is a potentially ideal combination of infraclavicular targeting, excellent needle visualization, single injection, safety, comprehensive upper extremity analgesia, rapid performance, and comfortable patient positioning. Herein we present the first description of the RAPTIR utilized in the ED. Our initial experience suggests this is a promising new technique for brachial plexus regional anesthesia in the ED setting.

The pericapsular nerve group (PENG) block is a novel ultrasound-guided regional anesthesia technique derived from recent anatomic studies detailing the sensory innervation of the hip. Targeting these terminal sensory branches, the PENG block was originally developed as a potentially more effective block for perioperative hip fracture anesthesia, with the added benefit of preserving motor function. Subsequent research with higher volumes of local anesthetic demonstrated the successful utilization of PENG block for perioperative acetabular fractures. This raises the possibility that the PENG block may have a role in the Emergency Department (ED) where regional anesthesia options for pelvic fractures are lacking. Herein, we present the first description of PENG blocks successfully used for pelvic fractures in the ED setting.

Pain control for patients in the Emergency Department (ED) with acute pancreatitis (AP) can be difficult and is often limited to intravenous opioids. The acute side effects from opioids are well known and their use in the treatment of AP is associated with prolonged length of hospitalization. Additionally, up to 10% of patients hospitalized for acute pancreatitis are still receiving opioids 6 months after discharge. Ultrasound-guided regional anesthesia by emergency physicians has increasingly proven to be an integral part of a multi-modal opioid sparing pain control strategy for patients in the ED. The ultrasound guided erector spinae plane block may be an ideal adjunct or alternative to opioids for analgesia from AP in the ED. The erector spinae plane block has already been successfully utilized by emergency physicians for pain control from rib fractures, herpes zoster, and more recently, acute appendicitis A lower thoracic erector spinae plane block targets sympathetic nerve fibers in addition to the dorsal and ventral rami via local anesthetic spread to the paravertebral space to provide both visceral and somatic analgesia. Herein, we present the first reported case of acute pancreatitis pain successfully managed by emergency physicians with the ESPB.

The ultrasound-guided transversus abdominis plane (TAP) block or TAP block is a well-established regional anesthetic block used by anesthesiologists for peri-operative pain control of the anterior abdominal wall. Multiple studies have demonstrated its utility to control pain for a range of procedures from inguinal hernia repair, laparoscopic cholecystectomies to cesarean sections [1-3]. There are no cases describing the efficacy of the ultrasound-guided TAP block in the emergency department as a part of a multimodal pain pathway for patients diagnosed with acute appendicitis. We developed a pain protocol in conjunction with our surgical colleagues that incorporates the TAP block to reduce opioid use, and better treat acute pain in patients with acute appendicitis diagnosed in the emergency department. We successfully performed ultrasound-guided TAP blocks in 3 patients with computed tomography confirmed appendicitis, reducing pain and need for further opioid use. This interdepartmental collaborative pathway could be an ideal anesthetic plan for patients diagnosed in the emergency department with acute appendicitis.

The Eastern Association for the Surgery of Trauma and Trauma Anesthesiology Society Guidelines recommend prompt and effective multimodal analgesia for rib fractures that combines regional anesthesia (RA) techniques with pharmacotherapy to treat pain, optimize pulmonary function, and reduce opioid related complications. However, RA techniques such as epidurals and paravertebral blocks, are generally underutilized or unavailable for emergency department (ED) patients. The recently described serratus anterior plane block (SAPB) is a promising technique, but failures with posterior rib fractures have been observed. The erector spinae plane block (ESPB) is conceptually similar to the SAPB, but targets the posterior thorax making it likely more effective for ED patients with posterior rib fractures. Our initial experience demonstrates consistent success with the ESPB for traumatic posterior rib fracture analgesia. Herein, we present the first description of the ESPB utilized in the ED.
