Lyostypt®
Local haemostatic agent
Indications
Lyostypt® is used for hemostasis of capillary bleeding, oozing hemorrhages, bleeding of parenchymal organs and as a supportive measure for other hemostasis techniques.
Advantages
- Efficient Hemostasis [1-3]
- Cost efficient [2]
- Absorbed in 3 weeks [4-6]
- Excellent biocompatibility [6]
COBBANA Trial
Control of bleeding in arterial bypass anastomosis [7]
- Prospective, randomized clinical trial
- Comparison of fibrillar collagen (Lyostypt®) versus oxidized regenerated cellulose (Surgicel®) [7]
- Hemostatic effect and handling properties were rated in suture hole bleeding of peripheral arterial bypass anastomosis using PTFE graft prosthesis
- N = 64 anastomoses (32 Lyostypt®, 32 Surgicel®)
Bleeding time of the anastomoses
- Fibrillar collagen showed significantly faster hemostasis (124 ± 67 sec) compared to oxidized regenerated cellulose (416 ± 226 sec) in suture hole bleedings of arterial bypass anastomosis [2]
Fibrillar collagen stopped suture hole bleeding of the anastomoses in less than 3 minutes in over 80 % of cases. Oxidized cellulose needed more than 5 minutes to stop suture hole bleeding in most of the anastomoses performed. [2]
Summary of Advantages of Lyostypt® vs Oxidized cellulose according COBBANA Trial [2]
- Faster hemostasis than oxidized cellulose in suture hole bleedings of arterial bypass anastomosis
- Better adhesion to tissue and surgical handling than oxidized cellulose in suture hole bleedings of arterial bypass anastomosis
- Lower amount of material needed to stop bleeding in comparison to oxidized cellulose
