Randomized Controlled TrialInfluence of head and neck position on performance of the Ambu® AuraGain™ laryngeal mask: a randomized crossover study.
The purpose of this study was to investigate the influence of different head and neck positions on the performance of the Ambu® AuraGain™, a novel laryngeal mask with anatomical curvature. ⋯ Head and neck position affects the oropharyngeal seal of the AuraGain™, as evidenced by the oropharyngeal leak pressure, but not enough to impede positive-pressure ventilation. Neck flexion can be used when a better oropharyngeal seal is needed, and neck extension and right rotation of the head and neck may facilitate endotracheal intubation using the AuraGain™ as a conduit.

Randomized Controlled Trial Comparative StudyA comparison of two different concentrations and infusion rates of ropivacaine in perineural infusion administered at the same total dose for analgesia after foot and ankle surgery: a randomized, double blinded, controlled study.
Continuous popliteal nerve block is utilized for postoperative analgesia after foot and ankle surgery. Whether only the total dose of local anesthetic or the combination of concentration and volume determine the characteristics of a continuous popliteal nerve infusion remains currently unknown. We hypothesized a reduction of the incidence of insensate extremity in patients given ropivacaine 0.4% at 4 mL/h compared to patients given ropivacaine 0.2% at 8 mL/h. ⋯ Our results suggest that local anesthetic total dose is the primary determinant of continuous popliteal perineural infusion effects.
