Deaths caused by recreational drug abuse have increased considerably in recent years. Therapeutic hypothermia offers the potential to improve neurological outcomes in post-resuscitation patients. ⋯ A 19-year-old man was brought to our emergency department after suffering out-of-hospital ventricular fibrillation (VF) cardiac arrest. He was resuscitated at our emergency department again due to VF. Urine analysis showed high levels of amphetamine and 3,4 methylenedioxymethamphetamine (MDMA) (ecstasy). The patient was intubated, sedated, and ventilated. Within 1 h after the return of spontaneous circulation and hemodynamic stabilization, therapeutic hypothermia was initiated for neurologic protection. An external-cooling device was used for cooling. He was maintained at 33oC for 72 h. The patient was weaned from the ventilator and extubated on day 5. He was discharged from the hospital on the day 10 with good cerebral performance. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Initiation of early therapeutic hypothermia within 1 h after return of spontaneous circulation might contribute to better neurologic outcome in patients who suffer VF cardiac arrest. We suggest that early therapeutic hypothermia may be considered in patients who suffer out-of-hospital cardiac arrest due to MDMA and amphetamine intoxications.

Although surface sonography has become an essential diagnostic tool in the evaluation of trauma patients, important limitations of this modality include the evaluation of retroperitoneal hemorrhage and mediastinal pathology, such as blunt traumatic aortic injuries (BTAI). As in other emergency applications where surface sonography can't provide the information needed, focused transesophageal echocardiography (TEE) may represent a valuable diagnostic tool in the evaluation of hemodynamically unstable trauma patients with suspected thoracic pathology such as BTAI. ⋯ We present a series of five cases that illustrate the diagnostic value of emergency physician-performed resuscitative TEE in the diagnosis of BTAI in patients presenting with blunt thoracic trauma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As the use of point-of-care TEE during resuscitation continues to expand in emergency medicine, the evaluation of patients with BTAI represents a novel application where this emerging modality can allow early diagnosis of these injuries in hemodynamically unstable patients.
