Background: Massive transfusions are associated with a high mortality rate, but there is little evidence indicating when such efforts are futile. The purpose of this study was to identify clinical variables that could be used as futility indicators in massively transfused patients.

Methods: We retrospectively analyzed 138 adult surgical patients at our institution receiving a massive transfusion (2016-2019).

Objective: To assess the ratio of non-red blood cell to red blood cell components required to avoid coagulopathy when transfusing large amounts of salvaged blood using laboratory test-guided therapy.

Design: Retrospective cohort study.

Setting: Single-center, academic hospital.

Background: Over the past decade, patient blood management (PBM) programs have been developed to reduce allogeneic blood utilization. This is particularly important in pancreatic surgery, which has historically been associated with high transfusion requirements and morbid event rates. This study investigated blood utilization and clinical outcomes in pancreatic surgery before, during, and after the implementation of PBM.

Background: The objective of this study was to determine if anesthesia providers can accurately estimate the cost of commonly used medications, supplies, and blood products.

Methods: This study was conducted between April and June 2019 at an academic tertiary care hospital. Anesthesia providers (certified registered nurse anesthetists [CRNAs], residents, and fellows/attendings) were surveyed on their knowledge of the cost of commonly used therapies.

Background: Transvenous lead extractions (TLEs) have increased in number due to an increased prevalence of cardiac implantable devices. Bleeding complications associated with TLEs can be catastrophic, and many institutions order blood components to be available in the procedure room. There are few studies supporting or refuting this practice.

Background: Patients requiring extracorporeal membrane oxygenation (ECMO) support are critically ill and have substantial transfusion requirements, which convey both risks and benefits. A retrospective analysis was conducted to assess the association between blood component administration and adverse outcomes in adult, pediatric, and neonatal ECMO patients.

Methods: We evaluated 217 ECMO patients at a single center hospitalized between January 2009 and June 2016.

Objective: Blood transfusions are given to approximately one-fifth of patients undergoing elective lumbar spine surgery, and previous studies have shown that transfusions are accompanied by increased complications and additional costs. One method for decreasing transfusions is administration of tranexamic acid (TXA). The authors sought to evaluate whether the cost of TXA is offset by the decrease in blood utilization in lumbar spine surgery patients.

Background: Patient blood management (PBM) is especially applicable in major spine surgery, during which bleeding and transfusion are common. What remains unclear in this setting is the overall impact of bundled PBM measures on transfusion requirements and clinical outcomes. We compared these outcomes before and after implementing a PBM program.
