    INTRAOPERATIVE TREATMENT I. HEMOSTATIC AGENTS

    A. Collagen in Surgery and Hemostasis

    1. Collagen for Testing Platelet Aggregation

    (1) Kabakibi A, Vamvakas EC, et al . COLLAGEN-INDUCED WHOLE BLOOD PLATELET AGGREGATION IN PATIENTS UNDERGOING SURGICAL PROCEDURES ASSOCIATED WITH MINIMAL TO MODERATE BLOOD LOSS. Am J Clin Pathol 1998 Apr;109(4):392-398

    Department of Pathology, Massachusetts General Hospital and Harvard Medical School, Boston 02114, USA. Intraoperative bleeding due to platelet disorders is a persistent problem. Therefore, a screening assay to identify patients who are likely to bleed as a result of platelet dysfunction would be useful in formulating decisions about patient care. A previous study indicated that preoperative collagen-induced whole blood platelet aggregation predicts bleeding in patients undergoing surgery with cardiopulmonary bypass, a procedure associated with substantial blood loss. In the current study, we assessed the ability of the same whole blood platelet aggregation test to predict blood loss in patients undergoing surgical procedures not associated with substantial blood loss. The study included 369 adult patients (165 men and 204 women). Patients with excessive blood loss (defined as blood loss at or above the 75th or 90th percentile of the estimated blood loss values of patients undergoing procedures of similar invasiveness) had similar platelet aggregation values as patients who did not experience excessive blood loss. Thus, for patients undergoing operations not associated with substantial blood loss, the results of preoperative collagen-induced whole blood platelet aggregation are not effective in identifying patients likely to experience excessive blood loss.

    Department of Anesthesiology, University of Texas Health Science Center, San Antonio. We assessed the ability of two commercial filters (Pall RC100 and Statlabs 20 microns) to filter out Avitene microfibrillar collagen hemostat from suspension. Quantitative determination of the collagen content as well as scanning electron and light microscopy, particle counting, and platelet aggregometry of filtrates revealed that these filters effectively remove potentially thrombogenic particles of Avitene microfibrillar collagen hemostat. The filters removed at least 97% of the total collagen, as determined by hydroxyproline analysis. The collagen that passed through the Pall filter did not pellet upon ultracentrifugation. Scanning electron and light microscopic analysis revealed no Avitene microfibrillar collagen hemostat particulates in the Pall filtrates but did reveal the presence of a significant number of approximately 1- to 8-microns particulates in the Statlabs filtrates. Concentrates of the filtrates from either of the two filters, however, did not promote platelet aggregation. Through ultracentrifugation and infrared analysis, the filtrates were found to consists of soluble, partially denatured collagen. The risk associated with the reintroduction of collagen particulates into the vasculature can be significantly reduced by use of appropriate, currently available blood-transfusion filters.

    Dr. Muller Hospital, Munich, Germany. Since the first clinical studies regarding sealing of arterial puncture sites with collagen with the use of the vascular hemostatic device (VHD) and the hemostatic puncture closing device (HPCD) in the early 1990s were performed, no analysis summarizing the published patients has been reported. Therefore we performed a Medline search of data as far back as 1990 and included abstracts presented at the major scientific meetings in the United States (American Heart Association, American College of Cardiology), Europe (European Society of Cardiology), and Germany (German Society of Cardiology). A total of 6007 patients were found to have been enrolled in studies with VHD (4448 patients) or with HPCD (1559 patients). Parameters analyzed in this review were hemostasis success rates and local complications. To assess the impact of the sealing device
