Atrial fibrillation after aortic arch repair requiring deep hypothermic circulatory arrest: incidence, clinical outcome, and clinical predictors.
To delineate the incidence, outcome impact, and clinical predictors of atrial fibrillation (AF) after adult aortic arch repair requiring deep hypothermic circulatory arrest (AAR-DHCA) AIMS: To determine the incidence of AF after AAR-DHCA, to determine whether AF after AAR-DHCA affects mortality or stay in the intensive care unit (ICU), to determine multivariate predictors for AF after AAR-DHCA, and to determine whether aprotinin protects against AF after AAR-DHCA. ⋯ AF after AAR-DHCA is common but does not independently increase mortality or ICU stay. The risk of AF after AAR-DHCA increases with age but decreases with the degree of hypothermia during DHCA. Aprotinin does not appear to affect the risk of AF after AAR-DHCA.

Randomized Controlled TrialEffects of alveolar recruitment on arterial oxygenation in patients after cardiac surgery: a prospective, randomized, controlled clinical trial.
Pulmonary atelectasis and hypoxemia remain considerable problems after cardiac surgery. The objective of this study was to determine the efficacy of consecutive vital capacity maneuvers (C-VCMs) to improve oxygenation in patients after cardiac surgery. ⋯ C-VCM is an effective method to reduce hypoxemia associated with the formation of atelectasis after cardiac surgery with CPB.

Patient understanding of the importance of beta-blocker use in the perioperative period.
Perioperative beta-adrenergic blockade has been shown to decrease morbidity and mortality after noncardiac surgery. The objective of this study was to determine patient knowledge of the importance of perioperative beta-blockade in a population already taking chronic therapy and to assess the effectiveness of medical and surgical providers in patient education regarding these benefits. ⋯ This study suggests low patient understanding of the potential importance and reasons for perioperative beta-blockade. Patients who recognized perioperative benefit identified antihypertensive versus cardioprotective effects. Clinicians can improve education of patients already taking daily beta-blockers regarding these potential benefits.
