Abstract
Cilj: Cilj ovoga istraživanja je dokazati elektrokemijsku stabilnost titanizirane kirurške mrežice u fiziološkoj otopini te dokazivanje stabilnosti pri promjeni fizoloških uvjeta. Metode: U ovom radu je mjerenjem potencijala otvorenog strujnog kruga te primjenom impedancijske spektroskopije ispitana elektrokemijska stabilnost medicinske titanizirane mrežice u standardnoj fiziološkoj otopini (pH 6.5) te fiziološkoj otopini snižene pH vrijednosti (pH 5.5). Rezultati: Dobiveni rezultati ukazali su na izrazitu stabilnost mrežice u fiziološkoj otopini (pH 6.5) te izuzetno zadovoljavajuću stabilnost u uvjetima koji odgovaraju upalnim procesima u organizmu (snižena pH vrijednost na 5.5). Zaključak: Ispitivanja mrežice ukazuju na zaključak da je mrežica izuzetno stabilna pri izlaganju fiziološkoj otopini i pH od 6.5 te je pokazala i stabilnost pri uvjetima koji simuliraju upalne procese u organizmu (pH 5.5).

Objective: Objective of this research is to prove electrochemical stability of titanized surgical mesh in saline, and to prove its stability during the changes of physiological conditions as well. Methods: By measuring potentials of open electric circuit and using impedance spectroscopy, stability of titanized medical mesh was tested in standard saline (pH 6,5), and also in saline with lower pH (pH=5,5). Results: Results showed outstanding mesh stability in physiological saline (pH 6,5), and exceptionally satisfying stability in conditions that are similar to inflammatory processes in the organism (pH lowered to 5,5). Conclusion: We can conclude, from the tests, that mesh is exceptionally stable when exposed to saline and pH 6,5, as well when is exposed to conditions that are simulating inflammatory processes in the organism (pH=5,5).
