Introduction: Pain scales are often used in peripheral nerve block studies but are problematic due to their subjective nature. Ultrasound-measured diaphragmatic excursion is an easily learned technique that could provide a much-needed objective measure of pain control over time with serial measurements. Case Series: We describe three cases where diaphragmatic excursion was used as an objective measure of decreased pain and improved respiratory function after serratus anterior plane block in emergency department patients with anterior or lateral rib fractures. Conclusion: Diaphragmatic excursion may be an ideal alternative to pain scores to evaluate serratus anterior plane block efficacy. More data will be needed to determine whether this technique can be applied to other ultrasound-guided nerve blocks.

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.

Author(s): Benesch, Tara; Mantuani, Daniel; Nagdev, Arun | Abstract: Introduction: The serratus anterior plane block (SAPB) has been shown to effectively treat pain following breast surgery, thoracotomies, and rib fractures. We present the first reported case of a bilateral ultrasound-guided SAPB in a multimodal analgesic regimen after an acute large, thoracic, deep partial-thickness burn. Case Report: A 72-year-old male presented in severe pain two days after sustaining a deep partial- thickness burn to his anterior chest wall after his shirt caught on fire while cooking. The area of injury was on bilateral chest walls, and the patient was consented for bilateral SAPBs at the level of the third thoracic ribs (T3). With ultrasound guidance, a mixture of ropivacaine and lidocaine with epinephrine was injected into the fascial plane overlying bilateral serratus muscles at T3. The patient reported complete resolution of pain for approximately 15 hours and required minimal additional intravenous analgesia. Conclusion: The ultrasound-guided SAPB may be an excellent addition to the multimodal analgesic regimen in superficial and partial-thickness burns of the anterior chest wall.

Introduction: Coronavirus disease 2019 (COVID-19) is caused by the virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several case series from Italy and China have highlighted the lung ultrasound findings of this disease process and may demonstrate its clinical utility during the current pandemic. Case Report: We present a case of a COVID-19 patient who presented to the emergency department twice within a 24-hour period with rapidly progressing illness. A multi-organ point-of-care ultrasound (POCUS) evaluation was used on the return visit and assisted clinical decision-making. Discussion: A multi-organ POCUS exam allows for quick assessment of acute dyspnea in the emergency department. As the lung involvement of COVID-19 is primarily a peripheral process it is readily identifiable via lung ultrasound. We believe that when applied efficiently and safely a POCUS exam can reduce clinical uncertainty and potentially limit the use of other imaging modalities when treating patients with COVID-19. Conclusion: This case highlights the utility of an early multiorgan point-of-care assessment for patients presenting with moderate respiratory distress during the severe SARS-CoV-2 pandemic.

Infectious flexor tenosynovitis (FTS) is a serious infection of the hand and wrist that can lead to necrosis and amputation without prompt diagnosis and surgical debridement. Despite the growing use of point-of-care ultrasound (POCUS) by emergency physicians there is only one reported case of the use of POCUS for the diagnosis of infectious FTS in the emergency department setting. We present a case of a 58 year-old man where POCUS identified tissue necrosis and fluid along the flexor tendon sheath of the hand. Subsequent surgical pathology confirmed the diagnosis of infectious FTS. [West J Emerg Med. 2015;16(2):260–262.]

A 61 year-old man presented to the Emergency Department for one day of nonspecific chest pain. Bedside echocardiogram performed by the emergency physician revealed normal systolic cardiac function but also showed a large ( > 10mm) bicornuate interatrial septal aneurysm (IASA) projecting into the right atrium (Figure 1, Video 1). There was no evidence of intraatrial thrombus. A formal echocardiogram performed later that day confirmed the diagnosis and also detected a patent foramen ovale (PFO) with a left-to-right shunt that reversed with Valsalva maneuver.
