Strategies for reducing blood transfusions in hepatic resection

Area of Science:

• Hepatobiliary Surgery
• Transfusion Medicine
• Surgical Outcomes

Background:

• Hepatic resection surgery often involves significant blood loss, leading to a high incidence of blood transfusions.
• Strategies to reduce intraoperative blood transfusions are crucial for improving patient outcomes and managing blood bank resources.

Purpose of the Study:

• To evaluate factors influencing the need for blood transfusions during hepatic resection.
• To identify strategies for reducing blood transfusions and associated complications in these patients.

Main Methods:

• A comparative study of 60 blood-transfused and 71 non-blood-transfused patients undergoing hepatic resection.
• Multivariate analysis was employed to identify predictors of intraoperative blood transfusion.
• Preoperative laboratory data, body weight, and operative blood loss were analyzed.

Main Results:

• Operative blood loss was significantly higher in the blood-transfused group (1990 ml) compared to the non-blood-transfused group (760 ml).
• Patient body weight, preoperative prothrombin time, and operative blood loss independently predicted the need for transfusion.
• Major postoperative complications occurred more frequently in the blood-transfused group (31.7%) versus the non-blood-transfused group (11.3%).

Conclusions:

• Prolonged prothrombin time and lower body weight are associated with increased operative blood loss and transfusion susceptibility.
• Improving preoperative prothrombin time and body weight, and reconsidering hematocrit as a sole transfusion trigger, may reduce blood loss and complications.
• Optimizing these factors can decrease reliance on blood transfusions, conserve blood bank resources, and lower the risk of adverse postoperative events.
