Review Meta Analysis
Depth of anesthesia measured by bispectral index and postoperative mortality: A meta-analysis of observational studies.
Whether anesthesia depth affects postoperative mortality remains uncertain. ⋯ We observed a significant relationship between deep anesthesia and long-term mortality, though this was not significant 30 days following surgery. In patients who had received cardiac surgery, deep anesthesia may increase mortality. However, this trend was not observed in patients who had undergone other forms of surgery.

This study aimed to explore the effects of platelet-rich plasmapheresis (PRP) on the amount of postoperative blood loss and the requirements for allogeneic fresh frozen plasma (FFP) and red blood cell (RBC) transfusions during cardiovascular surgery. ⋯ Conducting PRP before cardiopulmonary bypass (CPB) and transfusing autologous platelet-rich plasma (aPRP) after reversal of heparin could reduce postoperative blood loss, the requirements for blood products transfusion during cardiovascular surgery. A higher mean platelet count in aPRP may improve the final outcome. However, there was a high degree of undetermined heterogeneity among the analyzed trials, and larger and more precise RCTs are needed to confirm these conclusions.
