Cryoablation of atrial fibrillation in cardiac surgery: outcomes and myocardial injury biomarkers.
Elevations of myocardial injury biomarkers after cardiac surgery without ablation of atrial fibrillation (AF) are related to perioperative myocardial ischemia and associated with an increased risk of mortality and cardiac events. However, there have not been any studies that examined the release of cardiac biomarkers after AF cryoablation procedures with concomitant cardiac surgery. The authors determined the levels of these biomarkers for 2 different procedures involving cryoablation and assessed their clinical implications. ⋯ Cryoablation in cardiac surgery causes the release of very high levels of myocardial injury biomarkers. The modified CM lesion causes a greater elevation of serum biomarker levels than the isolated LA maze procedure, but this increase does not seem to have an adverse effect on rhythm or overall outcome. Cryoablation is a safe and effective surgical treatment for AF.

The effect of retrograde autologous priming of the cardiopulmonary bypass circuit on cerebral oxygenation.
The aim of this study was to investigate the effect of retrograde autologous priming (RAP) of the cardiopulmonary bypass (CPB) circuit on cerebral oxygenation. ⋯ The application of RAP to CPB limits the degree of hemodilution and improves cerebral oxygenation during CPB. The present findings suggest a potential benefit of RAP from a neurologic aspect.

Comparative StudyComparison of 5 different remifentanil strategies against myocardial ischemia-reperfusion injury.
The purpose of this study was to investigate the effects of various remifentanil strategies (preconditioning, postconditioning, or continuous infusion) against myocardial ischemia-reperfusion injury. ⋯ Preconditioning or postconditioning by remifentanil and the continuous infusion of remifentanil effectively reduce myocardial infarction, whereas reperfusion targeting ischemic targeting or reperfusion targeting remifentanil does not. Remifentanil preconditioning better preserves myocardial function, especially LVDP, than other remifentanil strategies.

Outcomes after rigid bronchoscopy in children with suspected or confirmed foreign body aspiration: a retrospective study.
To identify the determinants of immediate outcome after rigid bronchoscopy for suspected or confirmed foreign body (FB) aspiration. The outcome may be affected by the duration of bronchoscopy, the type of FB, the time between inhalation and removal of the FB, and the type of anesthetic induction. Arterial desaturation, bronco-laryngospasm, and the need for tracheal reintubation as complications were investigated. ⋯ Reducing the bronchoscopy time may not be an option, but an awareness of the risk of complications may prompt a more intense postanesthesia monitoring strategy.
