Use of a Topical Thrombin-Based Hemostatic Agent in Shoulder Arthroplasty.

Shoulder arthroplasty is associated with significant blood loss, often requiring blood transfusion. Hemostatic agents are used in various surgical specialties to minimize blood loss, but to date few studies have examined their efficacy in shoulder arthroplasty. We retrospectively reviewed 211 consecutive shoulder arthroplasty cases performed by a single surgeon. Our hypothesis was that patients treated with a topical thrombin prepared with a hemostatic matrix (Surgiflo) would have decreased perioperative blood loss. Patients with humeral fractures or preexisting blood disease were excluded. Control patients were managed December 2012 through April 2013. Study patients were managed May 2013 through August 2013 using the same surgical technique with the additional application of the hemostatic agent before closure. Charts were reviewed for demographics, estimated blood loss, drain output, transfusion rates, and complications. Hidden blood loss was calculated using a validated method. There were no differences in estimated blood loss (P = .301), drain output (P = .906), or hidden blood loss (P = .601) between groups. There was no increased incidence of transfusion between study (25%) and control (20%) groups (P = .407). No increased complications resulted from use of the hemostatic agent (P = .764). On the basis of these results, we cannot conclude that this topical hemostatic agent is effective as a blood loss management tool in shoulder arthroplasty.
