Endotracheal intubation is a common procedure in the emergency department, and new devices may improve intubation time, success, or view. ⋯ The KVVL was slightly faster than Macintosh DL in two of four studied airway scenarios, and had a higher success rate in the difficult cadaver airway scenario. Further study is required in the clinical setting.

Case Reports
Left-sided Superior Vena Cava and Venous Hyperoxia Masquerading as Inadvertent Carotid Artery Catheterization.
A persistent left-sided superior vena cava (PLSVC) is a rare, often asymptomatic, venous anomaly that may be first diagnosed during central venous catheterization. During chest radiograph interpretation, a PLSVC can be confused with inadvertent arterial catheterization. ⋯ We describe the presentation of a 45-year-old man with end-stage liver disease who required central venous catheterization for treatment of septic shock. An aberrantly placed catheter noted on chest radiograph and an elevated central venous oxygen saturation gave the appearance of inadvertent carotid artery catheterization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A persistent left-sided superior vena cava can masquerade as an inadvertent cannulation of the carotid artery during central line placement. It is important for emergency physicians to be aware of this possibility when evaluating a chest radiograph with an aberrantly placed catheter. Venous hyperoxia may further complicate attempts to differentiate between arterial and venous catheterization in patients with septic shock. After confirmatory tests, the emergency physician should consider removal of the catheter due to potential complications.

Case Reports
Retroperitoneal and Cutaneous Necrotizing Fasciitis Secondary to Necrotizing Pancreatitis.
Retroperitoneal abscesses are rare complications of intraabdominal infectious processes and can progress to necrotizing infections. Necrotizing pancreatitis occurs in 10-25% of patients that require hospital admission for pancreatitis, is associated also with a 25% mortality rate, and may lead to formation of a retroperitoneal abscess. ⋯ We report a case of a 63-year-old woman with a recently resolved case of pancreatitis who presented to the Emergency Department (ED) with a painful nodule on her left flank for 3 weeks, rapidly progressing over the last 12 h. In the ED, examination revealed an expanding area of erythema over the left flank with sepsis. Computed tomography scan revealed necrotizing pancreatitis with retroperitoneal abscess tracking to the abdominal wall, resulting in necrotizing fasciitis. She was taken emergently to the operating room with a good outcome. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute pancreatitis is common, with a minority of cases resulting in parenchymal necrosis, which can lead to retroperitoneal infections. Rarely, necrotizing fasciitis can present on the abdominal wall as a complication of intraabdominal or retroperitoneal infections. The emergency provider should be aware of these complications that may lead to necrotizing infections and a potentially indolent course.

Emergency physicians can utilize bedside ultrasound to aid in the diagnosis of abdominal wall hernias and in the reduction of incarcerated hernias. ⋯ A physician trained in bedside ultrasound can diagnose an abdominal wall hernia and facilitate the appropriate treatment of an incarcerated hernia.

Pelvic injuries in young children are rare, and it has been difficult to establish clinical guidelines to assist providers in managing blunt pelvic trauma, especially in non-Level 1 trauma centers. ⋯ Patterns of injury, based on mechanism of injury, have been reported to assist the assessment and management of children with minor pelvic injuries.
