RESUMO

Larva migrans is a cutaneous parasitic infection that occurs when an immature hookworm larva inadvertently penetrates the dermis of a human, typically on the extremities. Traditionally, a clinical diagnosis is made when a tortuous/serpiginous eruption is seen superficially in the skin with complaints of intense pruritus. Point of care ultrasound (POCUS) is a useful diagnostic tool for soft tissue complaints in the emergency department (ED). We describe a case of an 18-year-old woman who presented to the ED with foot pruritis four days after walking on the beach barefoot. POCUS examination revealed several motile structures in the dermis of the patient's foot, confirming our suspicion of cutaneous larva migrans. The patient was then placed on an oral anthelmintic and her symptoms resolved shortly after.

RESUMO

Introduction: Carpal tunnel syndrome (CTS) is a common complaint in the emergency department (ED) and accounts for approximately 90% of all peripheral neuropathies.6 Pain control from injection with corticosteroids into the carpal tunnel space is associated with multiple possible complications including atrophy, iatrogenic median nerve injury, and skin changes. Ultrasound (US)-guided mid-forearm median nerve block is an ED procedure that can be used to avoid direct injection into the carpal tunnel space. Here we present a case report proposing the use of US-guided mid-forearm block as a safe and effective adjunct to the management of acute pain caused by CTS. Case Report: A previously healthy 44-year-old, right-hand dominant female presented to the ED with left wrist pain. Her clinical exam and US findings were consistent with CTS. Given her allergy to non-steroidal anti-inflammatory drugs, she was offered a median nerve block, which was performed in the ED. The patient reported continued pain relief 24 hours after discharge from the ED. Conclusion: There is limited data on the use of US-guided mid-forearm median nerve block as an acute pain management tool for CTS in the ED. The US-guided median nerve block done in the mid-forearm location can provide pain control for those with CTS while reducing the risk of complications associated with direct carpal tunnel injection.

RESUMO

STUDY OBJECTIVE: We sought to initiate an emergency department (ED)-based ultrasound-guided regional anesthesia (UGRA) program in our community teaching hospital system. Here, we present our development process and protocol. We also sought to assess the types, indications, and associated adverse event rates for the UGRA procedures in this study. METHODS: We conducted a retrospective analysis of prospectively collected quality assurance data from a case series of patients who underwent an UGRA procedure in the ED. In August 2020, we developed an UGRA program for our community teaching hospital and its 2 affiliated freestanding EDs. For quality assurance purposes, we tracked all UGRA procedures performed in the ED, and we specifically assessed adverse events using structured follow-up. We subsequently obtained approval from our institutional review board to perform chart reviews of the patients in our dataset to abstract additional data and formally perform a research study. We determined the frequency with which different UGRA procedures were performed, and we calculated the adverse event rate. RESULTS: Between August 24, 2020, and July 15, 2022, a total of 18 different sonographers performed and documented 229 UGRA procedures on 206 unique patients. This included 28 different types of procedures. Follow-up after disposition was successful in 82.0% of patients. In 2 cases, the patient reported no pain relief at all from the procedure, but no patients reported complications related to the procedure. CONCLUSION: We successfully initiated a robust ED-based UGRA program in our community teaching hospital system. Among patients with successful follow-up, no adverse events were identified.

RESUMO

OBJECTIVES: Patients frequently present to the emergency department (ED) with neck or back pain, which can be difficult to treat. We sought to compare ultrasound-guided trigger point injection (TPI) to standard medications for patients with neck or back pain. METHODS: We performed a single-center, open label, randomized controlled trial on ED patients with neck or back pain from myofascial pain syndrome comparing ultrasound-guided TPIs to those who received the combination of a nonsteroidal anti-inflammatory drug (NSAID) and a muscle relaxant (MR). The primary outcome of this study was the reduction in mean pain score at the time of ED disposition. RESULTS: In total, we analyzed 196 patients. At the time of ED disposition, patients in the TPI group had a mean reduction in their pain scores of 45.0 mm as compared to 49.9 mm in the NSAID plus MR group (difference: 4.9 [95% confidence interval (CI) -3.0 to 12.7], P = .22). At the first reassessment, patients in the TPI group had greater pain reduction by 10.7 mm (95% CI 3.1 to 18.4). The rate of rescue therapy use was higher in the NSAID plus MR group (difference: 17.5% [95% CI 4.4 to 36.2]). CONCLUSIONS: We found no difference in pain reduction at the time of ED disposition between patients randomized to the ultrasound-guided TPI group as compared to those who received an NSAID plus a MR. However, patients in the TPI group had greater pain reduction at the time of first reassessment and lower rates of rescue therapy use.

RESUMO

Gluteal compartments can be difficult to assess for acute compartment syndrome (ACS) compared to other fascial compartments due to their anatomy and rarity of presentation. Point-of-care ultrasound (POCUS) needle guidance may assist in obtaining accurate compartment pressure measurements within the gluteal compartments. We present a case in which a 69-year-old woman presented following a fall resulting in a superior prosthetic hip dislocation. One-hour post hip-reduction, the patient began to experience severe pain of the right leg, swelling to the gluteal region, and numbness to her foot. With consideration of a developing gluteal compartment syndrome in mind, POCUS was used to guide the needle of a compartmental pressure monitor system into the gluteal maximus and medius-minimus compartments which demonstrated elevated compartment pressures consistent with ACS. The patient was subsequently taken for emergent fasciotomy and hematoma evacuation. There has been limited investigation into compartment pressure measurement under US guidance versus a palpation/landmark-guided technique. This case shows the feasibility of US needle guidance when assessing compartment pressures for this uncommon diagnosis.

RESUMO

BACKGROUND: 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. CASE REPORT: 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.

RESUMO

Aortic dissection (AD) is a "can't miss" diagnosis for emergency physicians. An algorithm combining the Aortic Dissection Detection Risk Score (ADD-RS) with D-dimer has been proposed as a high-sensitivity clinical decision tool for AD that can determine the need for advanced imaging. Here we present a case of a 48-year-old male who presented to the emergency department (ED) with chest pain and dyspnea. He had an ADD-RS score of 0 and negative D-dimer, which placed him in the low-risk category not requiring further advanced imaging. Despite this, he was found to have a pericardial effusion and dilated aortic root on point-of-care transthoracic echocardiogram (POC-TTE). These findings increased suspicion for AD and prompted the emergency physician to order a computed tomography angiography (CTA), revealing a thoracic AD. The patient successfully underwent surgical repair. This case demonstrates that the ADD-RS + D-dimer algorithm would have erroneously ruled out AD, without the inclusion of indirect findings of AD from the POC-TTE. This highlights the value of using POC-TTE as an adjunct to the ADD-RS + D-dimer algorithm in the diagnostic evaluation of AD and how giving more weight to indirect signs of AD on POC-TTE could potentially increase the sensitivity of the combined ADD-RS + D-dimer + POC-TTE algorithm.

RESUMO

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.

RESUMO

OBJECTIVE: To determine the impact of implementing a musculoskeletal in-service educational intervention for emergency medicine (EM) residents on the use of point-of-care ultrasound (POCUS) to diagnose and manage shoulder dislocations in the emergency department (ED). METHODS: This study was conducted in the ED of an academic teaching hospital in Miami, Florida. It consisted of a short in-service educational intervention on how to perform and interpret POCUS, followed by an open, prospective convenience sample study in patients with clinical suspicion of shoulder dislocation. Twenty EM residents, with no prior shoulder scanning training, participated in the study. In all of the cases, the findings of the shoulder US were compared with radiographs, which were considered the reference standard. EM residents enrolled patients, and obtained and interpreted the shoulder US images. RESULTS: Seventy-eight patients were evaluated to rule out shoulder dislocation and/or fracture. Diagnosis of the dislocated shoulder was made in 55 of 78 patients, 53 of whom had anterior dislocations. Resident-driven POCUS had a sensitivity and specificity of 100% to diagnose and rule out, respectively, shoulder dislocations and relocations. There were no differences in the number of dislocations diagnosed and relocated by early and advanced EM residents. Results from a POCUS were available 22 ± 2.8 minutes sooner than x-ray for initial diagnosis and 27 ± 2.9 minutes (P < 0.0001) sooner than x-ray for assessment of reduction. CONCLUSIONS: EM resident physicians, with no previous training in shoulder US imaging, exposed to a brief in-service musculoskeletal education intervention, were able to diagnose shoulder dislocations via POCUS with high sensitivity and specificity. Shoulder US for dislocation should be a core component in EM training.
