Comparative Study
Rapid development of brain hypothermia using femoral-carotid bypass.
Advances in the field of cardiopulmonary resuscitation have led to an increasing number of patients initially surviving sudden cardiac arrest. Unfortunately, most of these patients do not recover from the resultant anoxic brain insult. Several animal and human trials have suggested that post-resuscitative brain hypothermia may improve neurologic recovery after cardiopulmonary arrest. Present cooling methods are slow, induce only brain surface cooling, or result in systemic hypothermia. The authors tested the hypothesis that unilateral hypothermic carotid bypass would induce bilateral brain cooling without evoking systemic hypothermia or hemodynamic instability. ⋯ Femoral-carotid hypothermic bypass rapidly induced a state of selective brain hypothermia without causing systemic hypothermia or hemodynamic instability.

Small-bowel intussusception (SBI) for pediatric patients is unusual and difficult to diagnose preoperatively. This study sought to determine the sonographic findings of pediatric SBI. ⋯ Small-bowel intussusception is often over-looked due to nonspecific clinical presentations. Sonographic demonstration of a 2-3-cm sized, short, doughnut-like lesion, especially in the left abdomen or paraumbilical regions, should lead to strong suspicion of SBI.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Intranasal lidocaine for the treatment of migraine headache: a randomized, controlled trial.
To evaluate the effect of intranasal lidocaine for immediate relief (5 minutes) of migraine headache pain. ⋯ There was no evidence that intranasal lidocaine provided rapid relief for migraine headache pain in the emergency department setting.
