Abstract
Specialists in cardiothoracic and abdominal transplant anesthesia offer unique expertise and a vast breadth of knowledge that contribute to the management of these notably complex patients. Furthermore, these contributions extend beyond intraoperative management, to include leadership throughout the perioperative period, critical care medicine, and even global health. This issue of Seminars in Cardiothoracic and Vascular Anesthesia highlights this broad spectrum of expertise through original research, review articles, and case reports, spanning topics as diverse as airway management, coagulopathy, pediatric heart failure, echocardiography, and educational milestones for fellowship training for abdominal transplant. In the first article of the Original Research section, Auci et al present a retrospective, single-center, observational trial evaluating the optimal time to assess platelet dysfunction during cardiac surgery through the use of platelet aggregometry. In this trial of 63 patients, they utilized an adenosine-50-diphosphate (ADP)-test to compare platelet function at four separate time periods (baseline, aortic declamping, 10 minutes after protamine administration, and end of surgery). There were statistically significant differences in ADP-test results between almost all time periods, with one notable exception: aortic de-clamping vs 10 minutes following protamine. Clinically, this study demonstrates potential value in early identification of platelet dysfunction through assessment at the time of aortic de-clamping, thus allowing timely recognition and thus more effective treatment of platelet impairment following cardiopulmonary bypass (CPB). Anesthesiologists play an essential role for teams performing congenital cardiac surgery in resource-poor conditions throughout the world. To better characterize this work with the goal of improving participation and directing resources, Hubbard et al surveyed members of the Congenital Cardiac Anesthesia Society (CCAS). Survey participants (n = 108) reported 115 total trips to 41 countries spanning 5 continents. The survey covered a broad range of topics, including the nature of the work, trends in geographic locations, and factors that may influence an anesthesiologist’s participation in these efforts.
