In this month's POCUS Cases Dr. Rob Simard explains the role of POCUS in distal radius fracture diagnosis and reduction, how to troubleshoot finding the echogenic line that represents the shaft of the radius, and the limitations of using POCUS for distal radius fractures...
EM Cases Episode 82 Emergency Radiology Controversies, pearls and pitfalls: Which patients with chest pain suspected of ACS require a CXR? What CXR findings do ED docs tend to miss? How should we workup solitary pulmonary nodules found on CXR or CT? Is the abdominal x-ray dead or are there still indications for it's use? Which x-ray views are preferred for detecting pneumoperitoneum? When should we consider ultrasound as a screening test instead of, or before, CT? What are the indications for contrast in abdominal and head CT? How should we manage the patient who has had a previous CT contrast reaction who really needs a CT with contrast? What is the truth about CT radiation for shared decision making? And much more...
In this Journal Jam we have Dr. Michelle Lin from Academic Life in EM interviewing two authors, Dr. Rebecca Smith‑Bindman, a radiologist, and Dr. Ralph Wang an EM physician both from USCF on their article “Ultrasonography versus Computed Tomography for suspected Nephrolithiasis” published in the New England Journal of Medicine in 2014. There is currently a wide practice variation in the imaging work-up of the patient who presents to the ED with a high suspicion for renal colic. On the one extreme, some EM physicians use CT to screen all patients who present with renal colic, while on the other extreme, other EM physicians do not use any imaging on any patient who has had previous imaging. The role of POCUS and radiology department ultrasound as an alternative to CT in the work up of renal colic has not been clearly defined in the ED setting. This study was a pragmatic multi-centre randomized control trial of patients in whom the primary diagnostic concern was renal colic, that tried to answer the question: is there a significant difference in the serious missed diagnosis rate, serious adverse events rate, pain, return visits, admissions to hospital, radiation dose and diagnostic accuracy if the EM provider chose POCUS, radiology department ultrasound or CT for their initial imaging modality of choice. This Journal Jam is peer review by EMNerd's Rory Spiegel. [wpfilebase tag=file id=618 tpl=emc-play /] [wpfilebase tag=file id=619 tpl=emc-mp3 /]
In this episode on Appendicitis Controversies, we have the continuation of our discussion on abdominal pain emergencies with Dr. Brian Steinhart & Dr. David Dushenski. We kick off the discussion with key clinical pearls and pitfalls in the history and physical exam with their respective liklihood ratios when assessing patients with abdominal pain for appendicitis - a diagnosis that is still sometimes missed despite its prevalence. Dr. Dushenski hacks apart the Alvarado and Appendicitis Inflammatory Response Scores and we discuss the value of WBC, CRP and urinalysis in the work-up of appendicitis. Next up are the controversies of imaging algorithms using ultrasound and CT abdomen, as well as the factors affecting which imaging algorithm you might pursue. We wrap up the discussion on Appendicitis Controversies with a critical look at the value of antibiotics in the ED for appendicitis and which patients might be appropriate for non-surgical management.
In this episode, Dr. Jordan Chenkin & Dr. Jamie Blicker discuss positioning, landmarking, and best technique for lumbar puncture, how to minimize post-LP headache and traumatic taps, as well as when CT head is not required prior to LP. They discuss the indications, contraindications, trouble-shooting and pros and cons of needle aspiration, small bore pleural catheter with Heimlich valve and large bore chest tube for the treatment of spontaneous pneumothorax. Dr. Chenkin presents an intriguing argument for why he uses ultrasound-guided fracture reduction routinely in the ED, and we end with a few tips and tricks using skin adhesive for some unorthodox indications.
As a bonus to Episode 23 on 'Vaginal Bleeding in Early Pregnancy' with Dr. Ross Claybo and Dr. David Dushenski, we have here, Dr. Claybo's Best Case Ever. While vaginal bleeding in early pregnancy is rarely life threatening, there are a significant percentage of woman who will require emergency resuscitation and surgical intervention. We don't have mountains of RCTs on this topic; still Dr. David Dushenski & Dr. Ross Claybo run through the key clinical pearls of the history, the physical, interpretation of the BhCG and the value of serum progesterone in working up these patients. The newest on point of care ultrasound is discussed in the patient with vaginal bleeding in early pregnancy. The various types of spontaneous abortion including septic abortion are reviewed as well as the management of the unstable patient with massive vaginal hemorrhage. Ectopic pregnancy, in all it’s various presentations is reviewed with particular attention to the most common pitfalls and how to avoid them.

In Part 2 of this pediatric abdominal pain Episode - Pediatric Gastroenteritis, Constipation & Bowel Obstruction, Dr. Anna Jarvis, Canada's "mother of pediatric emergency medicine" and Dr. Stephen Freedman, one of Canada's pre-eminent researchers in pediatric GI emergencies, discuss the assessment, work-up and treatment of pediatric gastroenteritis, with particular attention to gastroenteritis & acute abdomen mimics, how best to assess hydration status, the nuances of the use of ondansetron and the prose and cons of various rehydration methods. A detailed discussion of the most common and lethal causes of acute abdomen bowel obstruction in pediatrics follows, including intussesception and midgut volvulus. Finally, the differential diagnosis and best management of the most common cause of pediatric abdominal pain, constipation, is reviewed.
In Part 1 of this Episode on Pediatric Abdominal Pain, Dr. Anna Jarvis, "the mother of pediatric emergency medicine" & Dr. Stephen Freedman, one of the world's pre-eminent pediatric EM researchers, discuss the nuances of the history, physical and work up of Pediatric Abdominal Pain & Appendicitis and key pearls on how to distinguish serious surgical causes from the very common diagnosis of gastroenteritis. An in-depth discussion on the pearls of the history, physical exam, lab tests, imaging including serial ultrasounds vs CT abdomen, clinical decision rules such as the Alvarado Score, best analgesics and antibiotics in pediatric appendicitis follows.
In Part 2 of this Episode on Emergency Ultrasound or Point of Care Ultrasound (POCUS) Dr. Fischer, Dr. Hannam, Dr. Chenkin & Dr. Hall, Canada's EM ultrasound gurus discuss how POCUS can help our decision-making in the pediatric patient with a limp, in the patient with necrotizing fasciitis, in the pregnant patient with vaginal bleeding and in the common and challenging elderly patient with undifferentiated abdominal pain. They cover POCUS indications from urinary retention to appendicitis and debate the utility of these indications. This is followed by a debate on how best to educate ourselves and the EM community in POCUS and how best to designs quality assurance programs so that point of care ultrasound (POCUS) becomes an accepted tool across the entire medical community.
