x Ultrasonography has revolutionized the ability of emergency physicians to integrate peripheral nerve blocks into a multimodal approach to pain management in the emergency department (ED). Injuries to the ankle and foot are common complaints in the ED that often require extensive manipulation in the course of stabilization and treatment. Numerous studies in the anesthesiology literature have demonstrated the efficacy of ultrasound-guided blockade of the distal sciatic nerve at the popliteal fossa for pain control related to below-knee surgeries.

x The suprascapular nerve (SSN) emerges from the upper trunk of the brachial plexus (C5-C6) and provides the majority of the sensory innervation to the glenohumeral and acromioclavicular joints. In addition, it provides motor innervation to the supraspinatus and infraspinatus muscles [1]. Blockade of the SSN was first described in 1941 by Wertheim and Rovenstine [2] and, since then, has been used extensively by anesthesiologists for a variety of conditions including adhesive capsulitis and postoperative pain control for shoulder arthroscopy [3].

x Retroperitoneal hematoma (RH) is an uncommon emergency but with a high mortality rate [1]. Clinical diagnosis is difficult because of variable presentations, from mild flank and upper abdominal discomfort to shock, depending on degree and duration of bleeding [1]. The causes of RH are traumatic, iatrogenic, or “spontaneous.” Treatment depends on the cause and ranges from drainage of hematoma under ultrasound guidance to surgery or endovascular procedures [1]. Ultrasonography (US) is increasingly important for initial assessment of critically ill patients [2,3].

x We read with great interest the paper recently published by Cortellaro et al titled “Contrast enhanced ultrasound versus chest x-ray to determine correct central venous catheter position” [1]. We agree with the authors' conclusion that contrast-enhanced ultrasound (CEUS) by itself cannot substitute chest x-ray in evaluating the catheter tip position after central venous catheter placement. Nevertheless, we would like to make some methodological comments. In a recent study [2] combining B-mode ultrasound with CEUS, we obtained an estimate of correct catheter position in atrio-caval junction that was much more accurate than in the study of Cortellaro et al (sensitivity 96% vs 33%, specificity 93% vs 98%).

x A 39-year-old woman presented to our emergency department 3 days after an assault. Initial evaluation demonstrated a right pneumothorax. Given her hemodynamic stability, a series of ultrasound-guided intercostal nerve blocks were performed. The indications, technique, and advantages of this approach are reviewed.

x Intraoral evaluation with ultrasound has been shown to be an ideal method for differentiating between peritonsillar abscess (PTA) and peritonsillar cellulitis. Unfortunately, many patients experience significant trismus and are unable to tolerate the intracavitary probe. Evaluation of the submandibular space with a high frequency linear transducer from the external aspect of the neck affords an alternative technique that has been shown to have high specificity for PTA. Unfortunately, there are no reported cases in the emergency medicine literature detailing this novel technique.

x Mediastinal hematoma is an uncommon finding in blunt chest trauma. It may be caused by aortic injury, by mediastinal vascular injury such as aortic injury, and by fractures of the sternum and vertebral column. A huge mediastinal hematoma can result in extrapericardial cardiac tamponade by compressing the adjacent organs. Although Focused Assessment with Sonography for Trauma (FAST) can reliably assess the presence of pericardial effusion in the subxiphoid view, it may overlook mediastinal hematoma.

x Posterior urethral valves are the most common cause of urinary obstruction in male children. Presentations of posterior urethral valves beyond the neonatal period include urinary tract infection, abdominal mass, renal failure, diminished urinary stream, crying during micturition, incontinence, dysuria, hematuria, or failure to thrive. Early diagnosis is imperative because early surgical relief of the obstruction is believed to help prevent the progression to end stage renal disease.

x Establishing airway in critically ill patients is of paramount importance because unrecognized esophageal intubation rapidly produces iatrogenic morbidity and mortality [1]. According to the 2010 American Heart Association guidelines, quantitative waveform capnography is recommended as the most reliable method for confirming endotracheal tube (ET) placement [2]. This study aimed to assess the diagnostic performance of bedside ultrasonographic techniques for confirmation of ET position in patients with cardiac arrest in a prospective, cross-sectional, cohort fashion.

x Until recently, emergency physicians in the prehospital setting had no tools with which to explore neurologic distress. In France, many emergency medical services are now equipped with hand-held ultrasound devices for use in the prehospital setting. The transcranial Doppler could contribute to better management of patients with head injury or ischemic stroke [1-3]; and the transcranial sonography (TS) could allow imaging of the brain parenchyma. Several brain disorders can be depicted by TS, such as intracranial hematomas, brain tumors, neurodegenerative disorders, and enlargement of the ventricular system [4,5].

A recent chart review reported an SAB rate of 10% among ED patients with a documented intrauterine pregnancy (IUP) and cardiac activity on ultrasound. We sought to prospectively evaluate outcomes among pregnant ED patients with documented cardiac activity on ultrasound.
