Abstract

U ovome radu uspoređivana je izdržljivost dvaju šivaćih materijala najčešće korištenih prilikom izvođenja gastrotomije – glikomera 631 i poliglikonata te utjecaj pH želučanog sadržaja na njihove karakteristike. Ispitivani šivaći materijal podijeljen je u 4 skupine, a u svakoj skupini nalazi se 4 ispitivanih uzoraka. U skupinama 1 i 3 nalaze se šivaći materijali koj nisu bili izloženi HCl-u dok su se u skupinama 2 i 4 nalazile šivaći materijali koji su bili izloženi HCl-u 5 dana. U skupinama 1 i 2 ispituju se svojstva glikomera 631 dok se u skupina 3 i 4 ispituju svojstva poliglikonata. Vrijednosti tlaka zabilježene prilikom popuštanja šavova kirurške rane želučane stijenke, broj uboda potrebnih za šivanje prvog i drugog sloja kirurške rane, mjesto popuštanja šavova kirurške rane želučane stijenke i volumen tekućine potreban kako bi se razvio tlak potreban za popuštanje šavova upisani su u računalne programe Excel for Windows, SPSS Software i Statistica 13.3 gdje su analizirani i statistički obrađeni. Na temelju dobivenih rezultata može se zaključiti kako HCl ima utjecaj na popuštanje šavova kirurške rane želučane stijenke.

Abstract (english)

In this paper the tensile strength and durability of two suture materials – Glycomer 631 and Polygliconate, were compared. Characteristics of this materials were also compared under the influence of HCl. Tested sutures were divides into four groups. Each group consisted of four samples. Groups one and three consisted of sutures which were not exposed to HCl, while sutures in groups two and four were exposed to HCl for five days. In groups one and two the properties of Glycomer 631 were tested, while in groups three and four we tested properties of Polygliconate. The recored values were pressure at the moment surgical wound broke, number of sutures on the first and second layer, volume of the liquid at the moment of wound breakage, and place where the sutures broke. The information sustained was entered into Excel, SPSS Software and Statistica 13.3 programme where they were analysed. Based on the results obtained, it can be concluded that HCl has an effect on loss of the tensile strength of Glycomer 631 and Polygliconate used for suturing gastric wounds.
