AbstractBleeding after total knee arthroplasty can result in significant morbidity and increases the need for blood transfusion. The proper use of intraoperative adjunctive topical hemostatic agents can enhance hemostasis perioperatively, potentially reducing blood transfusions. In this prospective study, 157 consecutive patients undergoing primary total knee arthroplasty received FLOSEAL (FLOSEAL Hemostatic Matrix; Baxter Healthcare Corporation, Hayward, California), a gelatin thrombin hemostatic matrix, 5 mL (74 patients) or 10 mL (83 patients). All patients received warfarin as thromboprophylaxis starting the day after surgery. Data were extracted via hospital chart review from 100 consecutive patients who underwent total knee arthroplasty and immediately preceded the FLOSEAL groups and did not receive FLOSEAL (control group). Postoperative drainage was significantly lower in the FLOSEAL 5 mL (236.9 mL) and 10 mL (120.5 mL) groups compared with the control group (430.8 mL; P<.0001 for both). The FLOSEAL 10 mL group had significantly less drainage than the FLOSEAL 5 mL group (P<.0001). The predicted probability of transfusion in the FLOSEAL 5 mL group was not significantly different compared with the control group (6.0% vs 7.6%, P=.650). The predicted probability of transfusion was lower in the FLOSEAL 10 mL group compared with the control group (0.5% vs 5.5%; P=.004). Within the FLOSEAL 10 mL group, application of FLOSEAL either before or after tourniquet release had a similarly significant effect on drainage volume and predicted probability of blood transfusion. No differences in outcomes were observed by type of anesthesia used. No adverse events occurred related to FLOSEAL use.Copyright 2015, SLACK Incorporated.
