Welcome to another ultrasound-based case, part of the “Ultrasound For The Win” (#US4TW) Case Series. In this peer-reviewed case series, we focus on real clinical cases where bedside ultrasound changed management or aided in diagnoses. In this case, a 101-year-old man presents after being found down with altered mental status.
Following intubation the confirmation of endotracheal tube placement and depth is essential. While dynamic etCO2 monitoring has revolutionized the confirmation of endotracheal placement, there are still several circumstances in which this modality may be misleading (e.g. prolonged arrest, severe status asthmaticus/PE/pulmonary edema, etCO2 detector contamination with drugs/gastric contents). Additionally, EtCO2 detectors cannot confirm appropriate endotracheal tube depth, leading to delayed recognition of mainstem placement.
One of the more common indications for the use of bedside ultrasound (US) is to evaluate patients who present to the emergency department (ED) with pain or bleeding during the first trimester of pregnancy. When performing this study, providers should be aware of several potential pitfalls that pose significant risk to both the patient and the provider.
Welcome to another ultrasound-based case, part of the “Ultrasound For The Win” (#US4TW) Case Series. In this peer-reviewed case series, we focus on real clinical cases where bedside ultrasound changed management or aided in diagnoses. In this case, a 46-year-old woman presents with history of right-sided abdominal pain and vomiting.
Are you getting a CT or bedside ultrasound as your first-line diagnostic approach to patients with undifferentiated abdominal or flank pain in whom you suspect kidney stones? In a landmark 15-center, multidisciplinary study published in the New England Journal of Medicine in September 2014, Dr. Rebecca Smith-Bindman (UCSF Department of Radiology) and her research team looked at exactly this question for emergency department patients. In the paper, “Ultrasonography versus CT for suspected nephrolithiasis,” Dr. Smith-Bindman and Dr. Ralph Wang (UCSF Department of Emergency Medicine) kindly joined us on a quick discussion about her paper.
Deep vein thrombosis (DVT) is always a consideration when patients with asymmetric lower extremity swelling. Why is one leg. Two-point focused DVT ultrasonography of the femoral and popliteal veins can be incredibly useful in the Emergency Department when trying to narrow the differential diagnosis. Drs. Margaret Greenwood-Ericksen, Joshua Rempell, and Mike Stone provide a clear, image-based clinical reference tool on this ultrasound technique.
Early 1st trimester pregnancies can be challenging to risk stratify when patient present with bleeding or pain. The pregnancy may be still too early for transabdominal ultrasonography, which was covered in last week’s PV card. The same authors, Drs. Matt Lipton, Mike Mallon, and Mike Stone provide a great bedside clinical reference tool on performing the focused transvaginal ultrasound in pregnancy.
