Background:Tisseel (Baxter International Inc., Westlake Village, CA, USA), a fibrin sealant, was originally devised to strengthen repairs of spinal cerebrospinal fluid (CSF) fistulas. Here, we evaluated how Tisseel correlated with hemostasis (e.g., defined as reduced postoperative drainage, time to drain removal, length of stay (LOS), and postoperative transfusion requirements) in 58 patients undergoing 2–3 vs. 79 patients having 4–6 level lumbar laminectomies.Methods:We assessed how Tisseel correlated with hemostasis in 58 patients undergoing 2–3 level laminectomies/stenosis (with 48 herniated discs and 20 synovial cysts, 1 degenerative spondylolisthesis) vs. 79 having 4–6 level laminectomies/stenosis (with 39 lumbar discs, 45 synovial cysts, and 26 degenerative spondylolisthesis).Results:Following 2–3 level laminectomies, the average drainage on postoperative day 1 was 87.26 cc, and on day 2 was 59.62 cc; most drains were removed and the majority of patients were discharged on postoperative day 2, requiring no transfusions. After 4–6 level decompressions, greater postoperative drainage was observed on postoperative days 1 (e.g., 156.63 cc), and 2 (115.8 cc), and many were continued for 3 (85.7 cc; 44 patients), and 4 postoperative days (93.6: 6 patients) respectively. Drains were typically removed and patients were discharged on postoperative days 3 and 4, with just 6 requiring transfusions. Notably, there were four CSF fistulas for patients undergoing 4–6 level laminectomies; one had a large disc hernation in conjunction with postoperative scare, while three had massive calcified synovial cysts extending to/through the dura.Conclusions:Utilizing Tisseel as a hemostatic allowed us to quantitate hemostasis (the average postoperative drainage, time to drain removal, LOS, and postoperative transfusion requirements) for those undergoing 2–3 level laminectomies vs. 4–6 level procedures with large subsets also exhibiting herniated discs, synovial cysts, and degenerative spondylolisthesis.
