[An analysis on blood transfusion for hepatic resection]

Area of Science:

• Hepatobiliary Surgery
• Transfusion Medicine
• Surgical Outcomes

Background:

• Hepatic resection surgeries often involve substantial blood loss.
• Minimizing blood loss and transfusion is essential due to associated adverse effects.
• Improvements in surgical techniques are needed to reduce intraoperative bleeding.

Purpose of the Study:

• To analyze intraoperative blood transfusion practices in hepatic resections.
• To evaluate the effectiveness of current blood management strategies.
• To identify areas for improvement in blood loss prediction and transfusion protocols.

Main Methods:

• Retrospective analysis of 42 hepatic resections performed in 2000.
• Evaluation of intraoperative blood transfusion data.
• Calculation of crossmatched to transfused (C/T) blood ratios for different resection types.

Main Results:

• Median blood loss varied by resection type, ranging from 1355 ml (nonanatomic) to 2298 ml (extended right resections).
• C/T ratios ranged from 0.90 (extended right) to 2.31 (segmental).
• C/T ratios for subsegmental (1.19) and extended right (0.90) resections were below the recommended 1.5-2.5 range.

Conclusions:

• Observed C/T ratios suggest potential for improved blood management in hepatic resections.
• Inappropriate blood loss prediction and underutilization of maximum surgical blood order schedule (MSBOS) or type and screen (T&S) likely contributed to lower C/T ratios.
• Implementing and optimizing MSBOS and T&S protocols can enhance transfusion efficiency and reduce unnecessary transfusions.
