Observational StudyAssociation of red blood cell transfusion and short- and longer-term mortality after coronary artery bypass graft surgery.
Red blood cell (RBC) transfusion has been linked to increased morbidity and mortality. However, strict RBC transfusion recommendations recently have been questioned. The aim of this study was to investigate the short- and long-term mortality outcomes after RBC transfusion in patients undergoing coronary artery bypass graft surgery (CABG). ⋯ In the present study, patients undergoing CABG surgery and receiving <6 U of PRBC did not have statistically increased risk for in-hospital mortality and up to 2 years postoperatively. A modestly statistically significant difference was noted at 3 years. However, cumulatively, there was no statistical difference between the transfused and nontransfused groups at 4 years. Further studies are needed to confirm the findings and define the population that will benefit the most from blood transfusion.

Randomized Controlled Trial Comparative StudyComparative Study Between Conventional Fasting Versus Overnight Infusion of Lipid or Carbohydrate on Insulin and Free Fatty Acids in Obese Patients Undergoing Elective On-pump Coronary Artery Bypass Grafting. A Prospective Randomized Trial.
Postoperative insulin resistance represents a major component of postoperative metabolic disorder. The authors compared the effects of preoperative infusion of lipid emulsion or carbohydrate to conventional preoperative fasting on postoperative insulin and free fatty acid (FFA) levels. ⋯ Preoperative lipid infusion lowered postoperative FFA, insulin, TG, VLDL, and random blood sugar in obese patients undergoing coronary artery bypass grafting surgeries.

Modified Tricuspid Annular Plane Systolic Excursion Using Transesophageal Echocardiography and Its Utility to Predict Postoperative Course in Heart Transplantation and Left Ventricular Assist Device Implantation.
Perioperative right ventricular (RV) function is important for determining the postoperative course in heart transplantation (HT) and left ventricular assist device (LVAD) implantation. The authors describe a modified tricuspid annular plane systolic excursion (m-TAPSE) using transesophageal echocardiography and assessed its clinical utility in HT and LVAD. ⋯ m-TAPSE validated a good correlation to RV systolic function as reflected by RV FAC for both HT and LVAD. For HT, m-TAPSE was helpful for predicting postoperative NO use; whereas for LVAD, m-TAPSE was helpful for predicting postoperative NO use and RV assist device implantation. m-TAPSE should be considered as a useful parameter to decide postoperative management for these cases.

ReviewPerioperative Information Systems: Opportunities to Improve Delivery of Care and Clinical Outcomes in Cardiac and Vascular Surgery.
A variety of existing perioperative informatics tools offer clinicians and researchers the opportunity to improve the delivery of care and clinical outcomes for patients undergoing cardiac and vascular surgery. Many of these tools can be used to improve the reliability of the care delivery process through the application of clinical decision support tools and/or quality improvement methodologies at a number of junctures. In this review, the authors will offer a concise overview of the existing perioperative informatics literature, with a focus on tools considered to be of utility in confronting the unique challenges inherent to cardiac and vascular surgery. The authors also highlight areas that they believe are of interest for future targeted inquiry.
