Randomized Controlled TrialParasternal intercostal block with ropivacaine for postoperative analgesia in pediatric patients undergoing cardiac surgery: a double-blind, randomized, controlled study.
The objective of this study was to assess the effectiveness of 0.5% ropivacaine used for parasternal intercostal blocks for postoperative analgesia in pediatric patients undergoing cardiac surgery. ⋯ Parasternal blocks with ropivacaine appear to be a simple, safe, and useful technique of supplementation of postoperative analgesia in pediatric patients undergoing cardiac surgery with a median sternotomy.

Cardiopulmonary bypass transiently inhibits intraventricular vortex ring formation in patients undergoing coronary artery bypass graft surgery.
Transmitral blood flow during early left ventricular (LV) filling produces an intraventricular rotational body of fluid known as a "vortex ring" that enhances the hydraulic efficiency of early LV filling. The authors tested the hypothesis that exposure to cardiopulmonary bypass (CPB) attenuates intraventricular vortex formation time (VFT) in patients with normal preoperative LV systolic and diastolic function undergoing coronary artery bypass graft (CABG) surgery. ⋯ The results indicated that CPB transiently attenuate VFT in patients with normal preoperative LV systolic and diastolic function undergoing CABG surgery. These data suggest that CPB adversely affects diastolic transmitral flow efficiency by reducing intraventricular vortex ring formation in vivo.

Anesthetic management of patients undergoing pulmonary vein isolation for treatment of atrial fibrillation using high-frequency jet ventilation.
The aim of this study was to describe anesthetic management and perioperative complications in patients undergoing pulmonary vein isolation for the treatment of atrial fibrillation under general anesthesia using high-frequency jet ventilation. The authors also identified variables associated with longer ablation times in this patient cohort. ⋯ High-frequency jet ventilation is generally a safe technique that can be used in catheter ablation treatment under general anesthesia.
