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.

Review Comparative Study
Cognitive impairment and postoperative outcomes in patients undergoing primary total hip arthroplasty: A systematic review.
Total hip arthroplasty (THA) is a common surgical procedure in the elderly. Varying degrees of cognitive impairment (CI) are frequently seen in this patient population. To date, there has been no systematic review of the literature specifically examining the impact of CI on outcomes after elective THA. The aim of this systematic review was to identify studies that compare the postoperative outcomes of patients with and without CI after undergoing elective primary THA. ⋯ We demonstrate that there are strong associations between patients with pre-existing CI undergoing THA and increased POD, hospital mortality, hospital complications, and hospital LOS. We report good quality evidence linking complications after THA to preexisting CI. Screening for CI can improve care and better predict the risk of developing postoperative complications such as delirium. Further investigations can address perioperative factors that can help reduce complications and show the utility of more widespread assessment of preoperative cognitive impairment.

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.

Comparative Study
The association of neuraxial versus general anesthesia with inpatient admission following arthroscopic knee surgery.
Arthroscopic knee procedures are increasingly being performed in an outpatient setting. Appropriate intraoperative anesthesia is vital to prevent complications such as unanticipated hospital admission. We examined differences in complications between general (GA) vs neuraxial anesthesia (NA) as the primary anesthetic for patients undergoing arthroscopic knee procedures. ⋯ NA was significantly associated with inpatient admission following knee arthroscopy. Further research should focus on examining the reason for this association and methods to reduce inpatient admission for patients undergoing arthroscopic knee procedures using neuraxial anesthesia.
