Randomized Controlled Trial
Evaluating time until ligation in a novel tourniquet - A crossover randomized-controlled trial.
Severe external hemorrhage is a significant reason for morbidity and mortality in adults; thus, the swift and correct application of a tourniquet by laypersons can be lifesaving. We conducted this randomized-controlled cross-over study to investigate the use of a novel tourniquet. ⋯ The novel PAX tourniquet can be applied quickly and effectively by medical personnel without prior experience in applying a tourniquet.

Ultrasound is an integral part of evaluating for acute cholecystitis and choledocholithiasis in pediatric patients. Finding the common bile duct (CBD), a structure which is normally <4 mm in children, can be very challenging. ⋯ The prevalence of isolated sonographic CBD dilation in pediatric patients with cholecystitis and/or choledocholithiasis was 1.1%. Thus, biliary ultrasound without CBD measurement is unlikely to result in missed cholecystitis and/or choledocholithiasis if the biliary ultrasound does not demonstrate GWT, PCF, SMS, or choledocholithiasis, and the patient has normal laboratory values.

Ischemic priapism is a relatively uncommon genitourinary condition that, if left untreated, can lead to permanent erectile dysfunction. Detumescence should ideally be attained within the first 36 h of onset to avoid irreversible fibrosis and necessary surgery. Opportunities to practice medical management of this condition are scarce, and the risk of iatrogenic injury of vessels, nerves, and urethra can be significant if performed blind. ⋯ To our knowledge, this is the first report of point-of-care ultrasound-guided penile nerve block used to manage pain associated with priapism. We present a 44-year-old male presenting with a painful erection lasting for eight hours. Penile doppler ultrasound was performed concurrent with medical management of priapism, with successful detumescence and discharge.

Bromvalerylurea (BVU) is a sedative-hypnotic drug with a high risk of acute poisoning. In the present case, hemodialysis (HD) was introduced in a patient with severe BVU poisoning who later demonstrated respiratory arrest, and then HD clearances (CLHD) were assessed in detail. A 20-year-old female was transported to the emergency department by ambulance, an estimated two to four hours after orally ingesting 144 tablets of Utto® (12,000 mg BVU) in a suicide attempt. ⋯ Serum BVU concentrations were determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The median CLHD was 133.61 mL/min, and the systemic clearance (CLSYS) was 117.77 mL/min. Higher CLHD of BVUs over CLSYS suggests that HD may play an important role in the treatment of severe BVU poisoning.

Case Reports
Obstructive myocardial infarction with normal automated ECG interpretation: A case report.
Emergency Medicine physicians experience a significant number of interruptions throughout their work day. One common cause of interruptions is the immediate interpretation of triage electrocardiograms (ECGs). Recent studies have suggested that ECGs interpreted as normal via automated analysis by the ECG machine rarely require urgent cardiac intervention and suggested that providers may not have to be interrupted to interpret these "normal" ECGs. We describe the case of a patient who presented to the Emergency Department (ED) with chest pain and an ECG interpreted as normal by an automated reading from the ECG machine, despite having acute coronary syndrome requiring emergent intervention.
