Targeted Bleeding Management Reduces the Requirements for Blood Component Therapy in Lung Transplant Recipients

Area of Science:

• Cardiovascular Surgery
• Transplantation Medicine
• Anesthesiology

Background:

• Lung transplantation frequently involves significant bleeding and requires substantial blood transfusions.
• Optimizing transfusion strategies is crucial for patient outcomes and resource management.

Purpose of the Study:

• To evaluate the impact of implementing point-of-care coagulation testing (POCCT) on transfusion requirements in adult lung transplant recipients.
• To assess changes in blood product utilization, postoperative bleeding, and associated costs following POCCT introduction.

Main Methods:

• A before-and-after cohort study analyzed 93 adult patients undergoing isolated lung transplantation.
• Point-of-care coagulation testing (ROTEM and multi-plate) with an associated algorithm was introduced as an intervention.
• Transfusion rates, chest tube blood loss, reoperation for bleeding, mortality, and costs were compared pre- and post-intervention.

Main Results:

• Significant reductions were observed in the proportion of patients receiving packed red blood cells (PRBCs), fresh frozen plasma (FFP), and platelets post-POCCT implementation.
• Median chest tube blood loss showed a small, statistically significant decrease at 2 and 4 hours postoperatively.
• No significant changes were detected in reoperation for bleeding or in-hospital mortality rates.
• The cost of administered blood products decreased substantially, from a median of $3,935.00 to $991.00.

Conclusions:

• The implementation of POCCT in lung transplant surgery is associated with significant reductions in blood product administration and associated costs.
• While early postoperative bleeding showed a minor decrease, POCCT did not appear to impact other major clinical outcomes.
• POCCT represents a valuable tool for optimizing transfusion management and reducing healthcare expenses in lung transplantation.
