| description | BACKGROUND. The development of new samples of local hemostatic agents is an intensively developing area of the modern industrial biotechnology due to a high need of clinical bases for such products. In addition to constant search for optimal substances used as a basis (collagen, cellulose and its derivatives, gelatin, etc.) for local hemostatic agents, methods for their comprehensive testing are also being developed. AIM OF THE STUDY. To evaluate the hemostatic activity of multicomponent polymer sponge implants using the coagulometer method developed by the authors in an in vitro experiment. MATERIAL AND METHODS. As research materials, new samples of multicomponent polymer sponge implants developed within the Laboratory of Experimental Surgery and Oncology of the Kursk State Medical University were used. The samples were based on marine collagen made from deep-sea squid in different ratios by weight with carboxymethylcellulose sodium salt (15/85, 25/75, 50/50). The hemostatic activity of these products was evaluated in the in vitro experiment using our method based on coagulometric measurement of blood clotting time of volunteer donors. Statistical processing of the data was carried out using methods of descriptive and variation statistics (Me [25; 75]). The validity of the difference was determined using the Mann–Whitney test (p ≤ 0,05). RESULTS. The blood clotting time in experimental group No. 2 turned out to be 2.12 s less than in the control group (the tested samples of hemostatic agents were not added). Statistically significant differences were found when comparing the values of coagulation time in experimental groups No. 3 (2.98 s less) and No. 4 (2.37 s less) with the values of the control group (No. 1). A decrease in the blood clotting time indirectly proves the effectiveness of the products used, due to the formation of the blood clot in a shorter period of time. This suggests that when the hemostatic agents are used in bleeding conditions, the products will reduce the time and volume of bleeding due to their hemostatic activity. CONCLUSION. Within the framework of the completed study, it was established that our method for assessing the hemostatic activity of local hemostatic agents, based on the evaluation of blood clotting time using electrocoagulometry, after grinding the tested samples, is easy to perform, accessible to most laboratories, and allows researchers to investigate the effectiveness of various forms of multicomponent polymer sponge implants. The development of multicomponent polymer sponge implants based on carboxymethylcellulose sodium salt and collagen seems to be a promising direction, since these products accelerate blood clotting time in the in vitro experiment. |
