Preoperative consultation for determining the appropriate transfusion strategy

Area of Science:

• Anesthesiology and Perioperative Medicine
• Hematology
• Surgical Outcomes Research

Background:

• Surgical patients face risks of postoperative complications and mortality.
• Preoperative optimization addresses modifiable risk factors.
• Current transfusion practices for bleeding and anemia lack proven efficacy in reducing mortality.

Purpose of the Study:

• To review complete blood count (CBC) abnormalities in surgical patients.
• To evaluate appropriate transfusion strategies for minimizing postoperative complications.
• To emphasize individualized patient optimization and reduced transfusion needs.

Main Methods:

• Literature review of studies on preoperative CBC abnormalities.
• Analysis of evidence regarding platelet and red blood cell transfusions.
• Examination of strategies for correcting hematological abnormalities preoperatively.

Main Results:

• Efficacy of preoperative platelet transfusions for bleeding remains uncertain.
• Red blood cell transfusion in anemia does not reduce postoperative mortality and may increase complications.
• Individualized strategies correcting CBC abnormalities are essential.

Conclusions:

• Minimizing transfusion requirements is crucial for improving surgical outcomes.
• Correcting preoperative complete blood count abnormalities is vital for patient safety.
• Further research into optimal transfusion thresholds and patient-specific strategies is needed.
