[Side effects of adhesion prevention by fibrinolytic drugs--in vitro studies of resorbable suture material and fibrin glue].

Surgical threads of a variety of resorbable suture materials (Cat plain and Chrom Cat, Serag Wiessner, Polyglactin 910 and Polydioxanon, Ethicon and polyglycolic acid, Dexon) were incubated up to 7 days at 37 degrees C in Varidase-containing media (Lederle Cyanamid, 1000 IU/ml in 0.9% NaCl or citrated human plasma). Thereafter the knot-breaking strength remained within 90.0 and 108.2% of the respective control threads (incubation in Varidase-free media, n = 7, n.s.). The dose-dependent lysis of fibrin glue by Varidase is effectively inhibited by small amounts of aprotinin (15 KIU/ml as compared with 1000-3000 KIU/ml in routine application). The inhibitor is bound to the matrix and not readily eluted.
