Intraoperative Risk Factors
Techniques to control intra-operative and postoperative bleeding for various orthopedic procedures including: Cell savage, antifibrinolytic agents (TXA), anesthetic techniques, patient positioning, surgical techniques, and local agents.
Some procedures recognized with increased risk for blood loss include:
- Spine deformity correction
- Pelvic osteotomies
- Revision procedures of the hip and knee
Surgeon Tools/Recommendations:
Preoperative Considerations:
- Important that management of potential blood loss begins before the patient enters the operating room
- Awareness of medication and supplements patient is taking at home that can increase risk of bleeding:
- Blood thinners: Aspirin, Plavix, warfarin, Xarelto, lovenox
- NSAIDs: Ibuprofen, naproxen, meloxicam, Celebrex
- Supplements: Garlic, ginkgo, ginseng, fish oil, flax seed oil, and saw palmetto
8-Step Checklist for Pre-, Intra-, Post-operative Reduction of Blood Loss in Total Knee and Total Hip Replacement
- Normalize preoperative hemoglobin
- Discontinue NSAIDs and anticoagulants before surgery
- Injection of IV TXA (10mg/kg) 30 minutes preoperatively and 4 hours postoperatively
- Local injection of ropivacaine, adrenaline and ketorolac before incision
- Careful hemostasis - dry wound
- Bone wax after femoral neck osteotomy (THA)
- Avoid hypertension throughout the anesthesia
- Efficient surgery with shortened operative times
