..Some military physicians teach compression of the distal abdominal aorta (AA) with a knee or a fist as a temporizing measure...

..This move has often been justified as a method to limit self-referral. However, clinicians may not be the only ones capable of referring imaging business to themselves...

..Emergency physicians using ultrasound frequently encounter unfamiliar findings during routine ultrasound examination. This is especially common for less experienced practitioners...

..We present 3 cases of isolated facial trauma in which routine evaluation with ocular ultrasound led to the discovery of periorbital air with one patient having air insufflating the upper lid of the affected side...

..We present 6 cases of Fournier's gangrene diagnosed in the ED at the patient's bedside using ultrasound. None of the patients had a history of diabetes, and 5 had sources of infection determined...

..There are a number of potential uses that may greatly aid the emergency physician (EP) and avoid lengthy consultation or other diagnostic tests...

..001), as compared with the palpation group. CONCLUSIONS: In this study, US guidance for arterial cannulation was successful more frequently and it took less time to establish the arterial line as compared with the palpation method...
