Ultrasound inferior vena cava (IVC) diameter has been shown to decrease in response to hemorrhage. IVC diameter cut points to identify moderate and severe blood loss have not been established. ⋯ An ultrasound IVCmax of ≤ 0.8 cm may be useful in identifying moderate and severe hemorrhage before vital sign abnormalities are evident.

The Impact of Pop-Up Clinical Electronic Health Record Decision Tools on Ordering Pulmonary Embolism Studies in the Emergency Department.
Emergency physicians make time-sensitive care decisions for life threatening diagnoses and utilize evidence-based decision rules and testing with high sensitivity to ensure that critical diagnoses are not missed. Current literature suggests that there is over testing for pulmonary embolism in the emergency department. ⋯ There are many barriers to the implementation of successful EHR alerts. These findings support and validate previous studies that have shown a higher diagnostic yield of CT angiography for pulmonary embolism after implementation of active alerts integrated into the EHR with ordering studies. These tools are effective quality improvement initiatives, and their use should be encouraged.

Multisystem inflammatory syndrome in children (MIS-C) is a newly recognized condition affecting children with recent infection or exposure to coronavirus disease 2019 (COVID-19). MIS-C has symptoms that affect multiple organs systems, with some clinical features resembling Kawasaki disease (KD) and toxic shock syndrome (TSS). ⋯ The diagnosis of MIS-C is based on clinical presentation and specific laboratory findings. In the emergency setting, a high level of suspicion for MIS-C is required in patients exposed to COVID-19. Early diagnosis and prompt initiation of therapy offer the best chance for optimal outcomes.

Emergency physicians frequently evaluate patients with postoperative wound issues. The differential is broad, but obviously includes postoperative site infections. We present a case where a suspected postoperative abscess was evaluated with bedside ultrasound prior to incision and drainage. Suture material was recognized, shifting our approach to treatment of the lesion. ⋯ A 24-year-old female patient presented with pain, swelling, and drainage from a left lower quadrant abdominal wound that had been present since undergoing a laparoscopic appendectomy 1 year prior. A computed tomography scan was performed, which was negative for foreign bodies. Prior to incision and drainage, a bedside ultrasound was performed to evaluate the lesion, which was notable for sonographic findings consistent with suture material. Suture granuloma was diagnosed, and ultrasound was then used to successfully guide retrieval of the suture. To our knowledge, this is the first published case where ultrasound was used to both diagnose and dynamically remove the offending suture material. We briefly discuss suture granulomas, their sonographic appearance, and management. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians frequently perform ultrasound on suspected abscesses prior to incision and drainage and should be aware of the sonographic appearance of suture material as it would change management if present. If a suture granuloma is suspected due to swelling at a postoperative site, ultrasound use should be strongly considered for evaluation.
