Episode notes
Preoperative Hemoglobin Optimization
- Optimize patient hemoglobin levels preoperatively with vitamin supplements like iron, folate, and B12 to improve stress tolerance during surgery.
- Use erythropoietin for high-risk patients but consider costs as it equals the price of four units of allogenic blood transfusion.
Tourniquet Use Recommendations
- Use a tourniquet during arthroplasty for a dry surgical field but avoid exceeding two hours in use.
- Avoid tourniquet in infection, tumor cases, and severe peripheral vascular disease without vascular consultation.
Tranexamic Acid Usage
- Administer tranexamic acid (TXA) perioperatively to reduce blood loss and transfusion rates without increasing DVT or PE risk.
- Avoid TXA in patients with stroke history, severe coronary artery disease, or allergy to TXA.
