The current state of scientific knowledge regarding communication between emergency medicine (EM) providers indicates that communication is critical to safe and effective patient care. ⋯ Our main finding of this research is that communication ensures shared awareness of patient health status, the care plan, status of plan steps and orders, and, especially, any critical changes or "surprises" regarding the health of a patient. Additionally, the research identified shared information needs; communication methods, strategies and barriers; and factors affecting successful communication, and has implications for both system and training design. Key implications for emergency nursing practice from this research are distilled in 10 'best practice' strategies for improving EM nurse-physician communication.

Case Reports
Intrathecal Baclofen Overdose With Paradoxical Autonomic Features Mimicking Withdrawal.
Intrathecal Baclofen (ITB) has become an increasingly common treatment for severe muscle spasticity associated with conditions such as cerebral palsy and spinal cord injury. Classically, withdrawal symptoms mimic symptoms of serotonin syndrome with hypertension, increased spasticity, clonus, hyperthermia, tachycardia, and possibly acute psychosis. Hypotension, muscle flaccidity, and respiratory depression are generally considered symptoms of toxicity or overdose. ⋯ We present the case of a male with recent ITB pump revision who presented with autonomic features suggestive of Baclofen withdrawal, while the remainder of his physical examination suggested appropriate medication dosing. Interrogation of the patient's ITB pump revealed normal function, and the patient had no clinical change with intravenous benzodiazepines, but his condition ultimately improved when his Baclofen dosing was decreased, indicating toxicity instead of withdrawal. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As Baclofen pump use increases, the importance of recognizing these potentially life-threatening complications also increases. This case presents the emergency physician with an atypical presentation and emphasizes the importance of a thorough neurologic examination to diagnose patients accurately.

Spinal epidural hematoma (SEH) after acupuncture is rare and may present with acute or subacute onset and varied symptoms, making it difficult to diagnose. This condition can mimic acute stroke, so it is vital to establish a clear diagnosis before considering thrombolytic therapy, which could be disastrous if applied inappropriately. ⋯ We describe a 52-year-old man who presented to our emergency department (ED) with acute onset of unilateral weakness of the limbs for 3.5 h immediately after receiving acupuncture at the bilateral neck and back. The acute stroke team was activated. In the ED, computer tomography angiography from the aortic arch to the head revealed spinal epidural hematoma. The patient was admitted to the ward for conservative treatment and was discharged with subtle residual symptoms of arm soreness 5 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute spinal epidural hematoma rarely presents with unilateral weakness of the limbs, mimicking a stroke. Because inappropriate thrombolysis can lead to devastating symptoms, spinal epidural hematoma should be excluded when evaluating an acute stroke patient with a history of acupuncture who is a possible candidate for thrombolytic therapy.

Melia azedarach, also known as the chinaberry tree, is native to Southeast Asia and northern Australia but has become an invasive species in the United States. M. azedarach contains limonoid tetranotriterpenes, found in highest concentrations in its berries. Ingestion has been reported to result in adverse clinical effects affecting the gastrointestinal, cardiovascular, respiratory, and neurologic systems. ⋯ In this study that focused on M. azedarach ingestions reported to Texas poison centers, the ingestions tended to involve berries. Most of the patients were young children. The ingestions often occurred between March and May. The ingestions typically were managed outside of a health care facility and did not result in serious outcomes. The most common clinical effects were gastrointestinal and neurologic.

Aortic transection, or aortic rupture, is a rare diagnosis in trauma patients and carries a high mortality. ⋯ We present the case of a 61-year-old man presenting to a Level I trauma center after being struck by a motor vehicle, found to have an aortic transection. He was initially hypotensive and resuscitated with blood products due to concern for hemorrhagic shock. Aortic injury was suspected after chest x-ray study demonstrated a widened mediastinum. Traumatic thoracic aortic transection with pseudoaneurysm was diagnosed on computed tomography of the aorta, and the patient was taken to the operating room for thoracic endovascular repair of the aorta. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Diagnosis of aortic injury can be challenging, especially in trauma patients presenting with hypotension. Aortic injury must be suspected in patients presenting after a high-velocity mechanism injury. It is an uncommon cause of hemorrhagic shock in trauma patients and must be considered even if other traumatic injuries are identified, as it commonly occurs with other significant injuries. Although chest x-ray study can be useful, a negative chest x-ray study does not rule out aortic injury. Aortic injury is a time-sensitive diagnosis, and early identification is key to these patients surviving to receive definitive management in the operating room.
