In trauma resuscitation with resuscitative endovascular balloon occlusion of the aorta (REBOA), urgent and accurate placement of the catheter in the resuscitation area without fluoroscopy can shorten the time from admission to REBOA, allowing rapid, temporary control of bleeding. ⋯ Ultrasound-guided REBOA is presented. Monitoring the blood pressure in the left radial artery allows us to determine adequate positioning of the balloon, and the blood pressure in the catheter sheath located in the femoral artery should also be monitored to prevent aortic injuries caused by the overinflation of the balloon.

Acute cerebrovascular accident (CVA) is a devastating cause of patient morbidity and mortality. Up to 10% of acute CVAs in young patients are caused by dissection of the vertebral or carotid artery. Wallenberg syndrome results from a CVA in the vertebral or posterior inferior artery of the cerebellum and manifests as various degrees of cerebellar dysfunction. The administration of a thrombolytic medication has been recommended in the treatment of patients with stroke caused by cervical artery dissection. Surprisingly, there is scant literature on the use of this medication in the treatment of this condition. ⋯ We describe a 42-year-old man with the sudden onset of headache, left-sided neck pain, vomiting, nystagmus, and ataxia 1 h after completing a weightlifting routine. Computed tomography angiography revealed a grade IV left vertebral artery injury with a dissection flap extending distally and resulting in complete occlusion. Subsequent magnetic resonance imaging and angiography demonstrated acute left cerebellar and lateral medullary infarcts, consistent with Wallenberg syndrome. The patient was treated with tissue plasminogen activator, which failed to resolve his symptoms. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians frequently manage patients with acute CVAs. For select patients, the administration of tissue plasminogen activator can improve outcomes. However, the risk of major hemorrhage with this medication is significant. Cervical artery dissection is an important cause of acute stroke in young patients and is often missed on initial presentation. It is imperative for the emergency physician to consider acute cervical artery dissection as a cause of stroke and to be knowledgeable regarding the efficacy of thrombolytic medications for this condition.

The majority of crashes cause "minor" injuries (i.e., treated and released from the emergency department [ED]). Minor injury crashes are poorly studied. ⋯ Driver-related risk factors are common in drivers involved in minor injury crashes, and drivers persist in taking risks after being involved in a crash. Despite their name, minor injury crashes are often associated with slow recovery and prolonged absenteeism from work.

Spilled gallstones are common during laparoscopic cholecystectomy; however, they rarely lead to postoperative complications. Perihepatic abscesses develop in < 0.1% of patients with spilled gallstones and are typically contained within the peritoneal cavity. ⋯ We present a 57-year-old man with history of cholecystectomy 2 years prior who presented with cough and flank pain and was discovered to have a perihepatic abscess invading his lung and kidney secondary to a spilled gallstone. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Although most perihepatic abscesses can be treated with percutaneous drainage and antibiotics, abscesses secondary to spilled gallstones usually require open or laparoscopic surgery to drain the abscess and retrieve the gallstone. Prompt identification of spilled gallstones in patients with intra-abdominal and intrathoracic abscesses can thereby guide disposition and decrease morbidity and mortality.

Case Reports Randomized Controlled Trial
The Use of Ketamine for Acute Treatment of Pain: A Randomized, Double-Blind, Placebo-Controlled Trial.
Pain is one of the most common reasons for emergency department (ED) visits in the United States. Ketamine is a sedative with N-methyl-D-aspartate (NMDA) receptor antagonism. Recent literature has suggested that the use of subdissociative dose ketamine (SDDK) may be safe and effective for acute pain. ⋯ When used as an adjunct, SDDK administered at 0.3 mg/kg over 15 min resulted in safe and effective analgesia for ≤30 min in patients who presented with acute pain in the ED.
