Review Meta AnalysisSociety of Cardiovascular Anesthesiologists Clinical Practice Update for Management of Acute Kidney Injury Associated With Cardiac Surgery.
Cardiac surgery-associated acute kidney injury (CS-AKI) is common and is associated with increased risk for postoperative morbidity and mortality. Our recent survey of the Society of Cardiovascular Anesthesiologists (SCA) membership showed 6 potentially renoprotective strategies for which clinicians would most value an evidence-based review (ie, intraoperative target blood pressure, choice of specific vasopressor agent, erythrocyte transfusion threshold, use of alpha-2 agonists, goal-directed oxygen delivery on cardiopulmonary bypass [CPB], and the "Kidney Disease Improving Global Outcomes [KDIGO] bundle of care"). Thus, the SCA's Continuing Practice Improvement Acute Kidney Injury Working Group aimed to provide a practice update for each of these strategies in cardiac surgical patients based on the evidence from randomized controlled trials (RCTs). ⋯ The decision to use a restrictive versus liberal strategy for perioperative red cell transfusion should not be based on concerns for renal protection (a moderate level of GRADE evidence). In addition, targeting a higher mean arterial pressure during CPB, perioperative use of dopamine, and use of dexmedetomidine did not reduce CS-AKI (a low or very low level of GRADE evidence). This review will help clinicians provide evidence-based care, targeting improved renal outcomes in adult patients undergoing cardiac surgery.

The provision of health services has been transforming from a largely top-down, paternalistic model into a construct in which patients play a substantive role in decision making over their care. Two articles in this month's issue of Anesthesia & Analgesia and an accompanying editorial address the growing momentum behind transparency in health care. Firstly, Quinonez et al consider the increasing expectation of family presence during surgical procedures and resuscitation of loved ones. ⋯ In conjunction with the increased desire for physical presence of loved ones during clinical procedures, so too is there a demand for complete access to all medical records, including even the arcane hieroglyphics of an anesthesia record as detailed by Ramaswamy et al. As federal law now mandates such access, questions naturally arise as to their utility and medicolegal implications. The reader is strongly encouraged to review the concepts elaborated in these articles for in depth appreciation of their considerations.
