Blood Management in Total Joint Arthroplasty James Prosser, DO Garden City Hospital
Introduction • Perioperative blood management techniques for orthopaedic surgery are critical to avoiding the risks and consequences associated with allogenic blood transfusion
Risks and Consequences • Blood-borne infections- Hep, HIV, HTLV, and CMV • Isoimmunization • Anaphylactic reaction • Hemolytic reaction
Risk of Transmission • HIV- 1 in 500,000 • Hep C- 1 in 100,000 • Hep B- 1 in 50,000
Other Allogenic Complications • Increased length of stay • Increased post-operative infection
Surgeon’s Goal • Reduce the need for allogenic transfusions of patients undergoing total joint arthroplasty
Methods to Reduce Allogenic Transfusions • Pre-operative • Intra-operative • Post-operative
Pre-operative Methods • Pre-operative planning -reduce time • Pre-operative Autologous Donation(PAD)
PAD • Red Cross Program most widely used • Between 12-70 years of age • Weigh atleast 110 pounds/ 1 unit • Hematocrit>34% • Last donation 1 week prior to surgery • Supplemental iron • Ferrous sulfate-320 mg TID • 1 week before donations to time of surgery
Drawbacks to PAD • Patient’s time and effort • Cost • Autologous donation>allogenic donation • Phlebotomy induced anemia • Average drop of 1g/dL(2 units donated)
Intra-operative Methods • Anesthesia • Hypotensive vs. Normotensive • Epidural vs. General • Time • decrease • Cell Saver • Cost- equipment and operator • Atleast 2 units of blood loss • Debris and infection
Post-operative Methods • Consta Vac drain • Initial 6 hours following surgery • Carried out by a ward nurse • <100 mL, reinfusion did not occur • Cheap • May prevent amount PAD
Breakthrough Transfusions • The need for allogenic blood in PAD patients
Transfusion Trigger • Defined as the standard protocol by which to transfuse • No common denominator • Historically • Hemoglobin – 10g/dL • Hematocrit – 30% • Physiologically • Vitals • Urine output • Individual(age, gender, medical history)
Study #1 • Sculco, T. and Gallina, J.: Blood Management Experience: Relationship Between Autologous Blood Donation and Transfusion in Orthopaedic Surgery. Orthopedics, 22(Supplement): S129-S134, January 1999. From The Hospital of Special Surgery, New York, NY.
Study #1 (continued…) • Retrospective case study review of 1405 patients who underwent elective uni-lateral/bi-lateral THA or TKA between 1994 and 1996 • All patients received; • Daily oral iron supplementation • Epidural hypotensive anesthesia • Post-op drains w/out transfusion
Study #1 (continued…) • Results • 83% participated in PAD • 80% PAD patients transfused • 50% non-PAD patients transfused • Hb<11, 90% transfused(1.5 units) • Hb>13, 50% transfused(.75 units) • 10% breakthrough transfusion • 40% PAD blood discarded
Study #1(continued…) • Conclusion • Unilateral, primary procedure with a pre-operative Hb>13, donate 1 unit • Revision, bi-lateral, pre-operative HB<13, donate 2 units
Study #2 Bierbaum, B.; Callaghan, J.; Galante, J.; Rubash, H.; Tooms, R.; and Welch, R.: An analysis of blood management in patients having a total hip or knee arthroplasty. J. Bone and Joint Surg., 81-A: 2-10, January 1999. From; New England Baptist, Mass General, University of Iowa, Rush Presbyterian, and Campbell Clinic.
Study #2(continued…) • 330 orthopods participate in study • Logistic regression analysis of 9482 patients evaluated from September of 1996 to June 1997
Study #2(continued…) • Results • 61% PAD patients • Hb>14, 8% allogenic • Hb<9, 62% allogenic • 9% breakthrough transfusion • 45% PAD blood discarded • 1g/dL decrease in PAD patients
Study #2(continued…) • Complications • Infection • No transfusion-3% • PAD-4% • Allogenic-7% • Length of stay • No transfusion-5.4 days • PAD-5.6 days • Allogenic-6.6 days
Study #2(continued…) • Conclusion • The variables that most consistently predicted the transfusion of allogenic blood were a low baseline Hb and a lack of PAD • The present study supports the strategy of reducing the number of units of PAD by patients with a higher Hb
Study #3 • Grosvenor, D.; Goyal, V.; Goodman, S.: Efficacy of Postoperative Blood Salvage Following Total Hip Arthroplasty in Patients with and without Deposited Autologous Units. J. Bone and Joint Surg., 82-A: 951-954, July 2000. From Stanford University Medical Center.
Study #3(continued…) • Retrospective case study of 156 patients undergoing unilateral, elective THA from October of 1997 to October of 1998 • 82 patients underwent post-operative blood salvage(PBS)- Group A • 74 patients without PBS- Group B
Study #3(continued…) • Results • 10% Group A received allogenic transfusion • 23% Group B received allogenic transfusions • EBL<300mL • Group A- 1% allogenic transfusion • Group B- 12% allogenic transfusion • EBL 300-600mL • Group A- 2% allogenic transfusion • Group B- 21% allogenic transfusion
Study #3(continued…) • Results • No PBS- 50% allogenic transfusion • No PAD- 60% allogenic transfusion • Neither- 100% allogenic transfusion
Study #3(continued…) • Conclusion • PAD resulted in the most substantial reductions in allogenic transfusions • PBS demonstrated a substantially lower risk of allogenic transfusion among PAD patients • May add an element of patient satisfaction to THA
Effect of Tourniquet on Blood Management • Aglietti, P.: Effect of Tourniquet Use on Activation of Coagulation in Total Knee Replacement. Clinical Orthopaedics and Related Research, 371: 169-177, 2000. From the University of Florence, Italy.
Parameters of Study • 20 patients undergoing TKA randomly assigned to two groups; one with a tourniquet and one without • No difference in age, gender, BMI, diagnosis, duration of surgery, and IV fluids
Results • Tourniquet group • Intra EBL- 350mL • Post EBL- 290mL • Total- 640mL • No tourniquet group • Intra EBL- 482mL • Post EBL- 145mL • Total- 627mL
The Future of Blood Management • Martinowitz, Beer-Sheva; Chanan-Tauber, Tel Hashomer; and Horoszowski, Rehovot.: The Use of Fibrin Tissue Adhesive to Reduce Blood Loss and the need for Blood Transfusion after Total Knee Arthroplasty. J. Bone and Joint Surg., 81-A: 1580-1586, November 1999. From Soroka Medical Center, Ben-Gurion University of the Negev, Beer-Sheva.
Adhesive • Fibrin tissue adhesive • Fibrinogen and thrombin • Mimic last step of coagulation cascade • Thrombin activates fibrinogen • Factor xiii activated • Cross link between fibrin molecules • Poor studies
Study • Multicenter, prospective, randomized, standard treatment controlled study with 58 patients with OA of the knee schedules to have unilateral, cemented TKA • 29 patients receive FTA • 29 patients without FTA
Procedure • Once prosthesis inserted with cement and before wound closure, 10-20mL applied by topically spraying with the use of a double syringe spray device • Cover entire joint surface
Results • Post-operative blood loss • FTA- 360mL • Non- 878mL • Decrease in Hb • FTA- 25g/L • Non- 37g/L • Total calculated blood loss • FTA- 1063mL • Non- 1768mL • Transfusion requirements • FTA- 17% • Non- 55%
Conclusion • FTA reduced apparent blood loss, drop in Hb, total blood loss, and transfusion requirements
