Randomized Controlled Trial Comparative Study
Randomized prospective trial comparing two supraglottic airway devices: i-gel™ and LMA-Supreme™ in paralyzed patients.
Many features can influence the choice of a supraglottic airway device (SAD), including ease of insertion, adequate ventilation pressures and lack of adverse effects. The goal of this randomized prospective trial was to compare the performance of the i-gel™ with that of the LMA-Supreme™. ⋯ Both the LMA-Supreme and the i-gel offer similar performance for positive pressure ventilation in paralyzed patients during general anesthesia. The i-gel was associated with a slightly faster insertion time and better fibrescopic visualization of the glottis. This trial was registered at Clinicaltrials.gov: NCT01001078.

Randomized Controlled Trial
Preoperative beta blocker use associated with cerebral ischemia during carotid endarterectomy.
Cerebral ischemia is a known complication of carotid cross-clamping during carotid endarterectomy. Selective intraluminal shunting for cerebral protection is not always effective and carries risks. The purpose of this study was to identify potentially modifiable risk factors for intraoperative cerebral ischemia and shunting during carotid endarterectomy. ⋯ The current study found an association between regular preoperative use of beta blockers and intraoperative cerebral ischemia in patients undergoing carotid endarterectomy. This effect did not relate to intraoperative hemodynamics.
