Comparative Study
Preoperative screening and intervention for mild anemia with low iron stores in elective hip and knee arthroplasty.
Preoperative anemia in patients undergoing elective hip and knee arthroplasty is associated with increased postoperative morbidity and mortality, red blood cell (RBC) transfusion, and length of stay (LOS). The aim of this study was to assess the effect of optimizing hemoglobin (Hb) levels before elective primary hip and knee arthroplasty. ⋯ Algorithm-led preoperative anemia screening and management in elective arthroplasty was associated with reduced RBC transfusion, readmission, critical care admission, LOS, and costs.

Major bleeding in orthotopic liver transplantation is associated with significant morbidity and mortality. Limited literature exists regarding comparative effectiveness of prothrombin complex concentrate and fibrinogen concentrate during orthotopic liver transplantation on blood product utilization. ⋯ The intraoperative use of prothrombin complex concentrate and fibrinogen concentrate during orthotopic liver transplantation did not reduce intraoperative blood product requirements at a single institution.

Randomized Controlled Trial
The effects of storage of red blood cells on the development of postoperative infections after noncardiac surgery.
Prolonged storage of red blood cells (RBCs) is a potential risk factor for postoperative infections. The objective of this study was to examine the effect of age of RBCs transfused on development of postoperative infection. ⋯ Prolonged RBC storage time did not increase the risk of postoperative infection. However, old blood transfusion increased wound infections rate and incidence of AKI.

The objective was to identify risk factors associated with blood transfusion in patients undergoing high-order Cesarean delivery (CD). ⋯ In patients undergoing a third or more CD, only placenta previa, prophylactic anticoagulation during pregnancy, and having labored are independently associated with requiring a blood transfusion. These data can be used to guide physician ordering of prepared blood products preoperatively.

Central venous catheters are frequently inserted into patients with coagulation disorders. It is unclear whether preprocedural correction of hemostasis is beneficial. We determined the incidence of bleeding complications after central venous catheter placement in patients who had severe coagulopathy and identified potential risk factors for bleeding. ⋯ The incidence of major bleeding complications after central venous catheter placement is low, even in coagulopathic patients. Based on a systematic research of the literature, strong evidence supporting the correction of hemostatic defects before central venous catheter insertion is lacking. However, well-powered randomized controlled trials will be necessary to determine the minimal platelet count, the maximal international normalized ratio, and an activated partial thromboplastin time that is safe before central venous catheter insertion.
