To determine whether warm lavage liquid ventilation (LV) would provide rapid cardiopulmonary rewarming in swine with severe hypothermia and ventricular fibrillation. ⋯ During cardiac arrest, warm lavage liquid ventilation may produce rapid cardiopulmonary rewarming.

The efficacy of esmolol versus lidocaine to attenuate the hemodynamic response to intubation in isolated head trauma patients.
To assess the effect of esmolol vs lidocaine to attenuate the detrimental rise in heart rate and blood pressure during intubation of patients with isolated head trauma. ⋯ Esmolol and lidocaine have similar efficacies to attenuate moderate hemodynamic response to intubation of patients with isolated head trauma.

Randomized Controlled Trial Clinical Trial
The effect of lower-extremity position on cerebrospinal fluid pressures.
To determine the effects of lower-extremity positioning on cerebrospinal fluid opening pressure (CSFp). The authors believed that during lumbar puncture (LP), CSFp does not meaningfully decrease when the lower extremities are extended from flexion, as is often suggested. ⋯ Changing lower-extremity position did not meaningfully change mean CSFp. These data do not support the common suggestion that extending the lower extremities during LP meaningfully decreases CSF opening pressures.

Acute scrotal pain is not a rare emergency department (ED) complaint. Traditional reliance on medical history and physical examination can be precarious as signs and symptoms can overlap in various etiologies of acute scrotal pain. ⋯ This study suggests that EPs using bedside ultrasonography are able to accurately diagnose patients presenting with acute scrotal pain. In addition, they appear able to differentiate between surgical emergencies, such as testicular torsion, and other etiologies.
