Tisseel does not reduce postoperative drainage, length of stay, and transfusion requirements for lumbar laminectomy with noninstrumented fusion versus laminectomy alone

BACKGROUND: Typically, fibrin sealants (FSs) and fibrin glues (FGs) are used to strengthen dural repairs during spinal surgery. In 2014, Epstein demonstrated that one FS/FG, Tisseel (Baxter International Inc., Westlake Village, CA, USA) equalized the average times to drain removal and length of stay (LOS) for patients with versus without excess bleeding (e.g. who did not receive Tisseel) undergoing multilevel laminectomies with 1-2 level noninstrumented fusions (LamF).[6] METHODS: Here Tisseel was utilized to promote hemostasis for two populations; 39 patients undergoing average 4.4 level lumbar laminectomies with average 1.3 level noninstrumented fusions (LamF), and 48 patients undergoing average 4.0 level laminectomies alone (Lam). We compared the average operative time, estimated blood loss (EBL), postoperative drainage, LOS, and transfusion requirements for the LamF versus Lam groups. RESULTS: The average operative times, EBL, postoperative drainage, LOS, and transfusion requirements were all greater for LamF versus Lam patients; operative times (4.1 vs. 3.0 h), average EBL (192.3 vs. 147.9 cc), drainage (e.g. day 1; 199.6 vs. 167.4 cc; day 2; 172.9 vs. 63.9 cc), average LOS (4.6 vs. 2.5 days), and transfusion requirements (11 LamF patients; 18 Units [U] RBC versus 2 Lam patients; 3 U RBC). CONCLUSIONS: Utilizing Tisseel to facilitate hemostasis in LamF versus Lam still resulted in greater operative times, EBL, postoperative average drainage, LOS, and transfusion requirements for patients undergoing the noninstrumented fusions. Although Tisseel decreases back bleeding within the spinal canal, it does not reduce blood loss from LamF decorticated transverse processes.
