Clinical TrialCan Transesophageal Echocardiography Be Performed Safely Using a Laryngeal Mask Airway During Atrial Fibrillation Ablation?
To investigate the feasibility and safety of using a laryngeal mask airway (LMA) compared with a cuffed oral endotracheal tube (COETT) for atrial fibrillation (AF) ablation with transesophageal echocardiography (TEE). ⋯ LMA use is safe and feasible in the vast majority of patients undergoing AF ablation with TEE and is an acceptable alternative to COETT. A significantly reduced rate of remifentanil was required to maintain anesthesia in the LMA group.

Review Meta AnalysisPhosphocreatine in Cardiac Surgery Patients: A Meta-Analysis of Randomized Controlled Trials.
There is experimental evidence that phosphocreatine (PCr) can decrease ischemia/reperfusion injury of the heart. The authors investigated if PCr would improve heart performance as compared with standard treatment in cardiac surgery. ⋯ In randomized trials, PCr administration was associated with reduced rates of intraoperative inotropic support and major arrhythmias, and increased spontaneous recovery of the cardiac rhythm after aortic declamping. Large multicenter evidence is needed to validate these findings.

Observational StudyReappearance of Motor-Evoked Potentials During the Rewarming Phase After Deep Hypothermic Circulatory Arrest.
Although motor-evoked potentials (MEPs) disappear in deep hypothermic circulatory arrest (DHCA), MEPs have been used to confirm whether motor function is intact after DHCA. It is crucial to know the timing, body temperature, and MEP amplitude at MEP reappearance to detect spinal cord ischemia after DHCA. However, data on these parameters are sparse. The authors investigated the characteristics of MEPs at reappearance after DHCA. ⋯ There was a wide variation in MEP amplitude at reappearance during the rewarming phase. BT was approximately 34°C when MEPs in the leg recovered. The time to MEP reappearance is influenced significantly by rewarming time and BT.
