Mubuzima, bikunze kubaho ko ikiganza cyaciwe kubwimpanuka kandi amaraso adahagarara. Umuhungu muto yashoboye guhagarika kuva amasegonda make abifashijwemo na gaze nshya kugirango areke kuva amaraso. Nukuri biratangaje?
Igitabo chitosan arterial hemostatic gauze ihagarika kuva amaraso ako kanya
Amaraso niyo soko yubuzima, kandi gutakaza amaraso birenze urugero nintandaro yurupfu rwihungabana. Kw'isi yose, abantu miliyoni 1.9 bapfa buri mwaka bazize gutakaza amaraso menshi. Ati: "Niba umuntu apima ibiro 70, ubwinshi bwamaraso yumubiri bingana na 7% byuburemere bwumubiri, ni ukuvuga miriyoni 4900, niba gutakaza amaraso birenga miriyoni 1.000 kubera ihungabana ryimpanuka, ni akaga kubuzima." Ariko iyo ubufasha bwubuvuzi bugeze, ubufasha bwambere busanzwe ni ugupfuka igikomere igitambaro, imyenda, nibindi, bishobora gukora mugihe amaraso ava mumitsi cyangwa capillary, ariko niba imiyoboro y'amaraso ivuye mumaraso, ingamba nkizo zo kuvura indwara ntizihagije. ”
Mu kuvura byihutirwa mbere y’ibitaro, kugenzura neza amaraso y’abarwayi ku nshuro yambere ni urufunguzo rwo kubona igihe cyo kwivuza no kurokora ubuzima.
Vuba aha, chitosan yihuta ya arterial hemostatic gauze yamenyekanye kumasoko. Iyi gauze ifite agace ka chitosani idasanzwe. Granules ya Chitosani ihujwe na gaze yuzuye cyane ituma gupakira byihuse no gukomera cyane kumubiri. Chitosan granules ifata ingirangingo zitose mu gikomere, zitezimbere tamponade ya gaze no kugenzura gutakaza amaraso.
Inzira idasanzwe ya hemostatike
Ifata amazi ava mumaraso ikora geli ikusanya selile zitukura kugirango ikore amaraso.Kureka kuva amaraso 100%, shyira witonze igice cyigitereko cya hemostatike mumyanya y igikomere, kashe (tampon) hanyuma ufate, ukanda mumaboko yawe , mu minota 5. Muri iki gihe, amaraso azuzuza bande, granules ya chitosan irakora, irabyimba ihinduka gele yuzuye. Ubwinshi bwa jel buzahagarika imitsi iva amaraso, ihagarike kuva amaraso, kandi ikore gel kugirango ifunge igikomere. Muri icyo gihe, chitosan ihuza ingirangingo z'amaraso zitukura kugira ngo ikore geles, ishobora kandi kwirinda neza ko bagiteri yanduza igikomere.
Iyi mitsi ya hemostatike irashobora kugenzura byihuse kuva amaraso mu buryo butagereranywa kandi bukabije buterwa nihungabana, harimo no kugenzura neza amaraso ava mumaraso mu minota itatu, kandi ntibizatanga umuriro. Usibye kuba bikwiranye no kuva amaraso mu maraso, birashobora no gukoreshwa ibikomere bitagaragara. Ahantu igikomere ntigarukira, kandi umutwe, ijosi, igituza, inda nibindi bice byumubiri birashobora gukoreshwa neza. Imiyoboro ya hemostatike ifata cyane ku gikomere, bikagabanya ibyago byo kwandura indwara ziterwa n'amaraso, kandi bikaguma aho mu gihe uwahohotewe atwarwa, bikarinda kuva amaraso ya kabiri. Amaraso arashobora kwifata muminota mike nyuma yo kwisuka mubikomere, kandi ibibyimba biroroshye kubikuramo kandi birashobora gukaraba byoroshye n'amazi cyangwa umunyu. Uburyo bwo gukora iyi gauze ya hemostatike ntibiterwa nimpamvu ziterwa na coagulation mumaraso, bityo bigira akamaro mumaraso ya heparine. Urebye amazi yimyunyu ngugu iterwa no gukomeretsa kwinjira, iyi gaze ya hemostatike irashobora kugira uruhare mukuziba umuyoboro wimyanda kandi ikarinda amazi yigifu kwangirika kwumubiri. Hemostasis ku gihe kandi ikora neza kandi igabanya gutakaza amazi yumubiri, igabanya ihungabana, irinda neza igikomere, kandi irinda kongera gukomeretsa ingirangingo.
Byongeye kandi, gaze ya hemostatike ntabwo ihindurwa nubushyuhe bwibidukikije kandi iracyakora neza mubushyuhe bwamaraso bwa 18.5 ° C. Ubuzima bwo kubaho ni imyaka 5 kandi nta buryo bwihariye bwo kubika busabwa. Gukoresha ibikoresho bidafite amazi bipfunyika, byoroshye gutwara, byoroshye gukora, amabwiriza yo kwishyiriraho umwuga ntabwo ashobora gukoreshwa vuba. Nibisanzwe, bisukuye cyane, nta reaction ya allergique mumateka yimikoreshereze, ntabwo ari uburozi, butari kanseri, kandi ntibukingira indwara. Chitosani yimbitse yo mu nyanja yakuwe muri krill yimbitse yo mu nyanja ku burebure buri hejuru isukurwa n’ikigereranyo cya zahabu, ifite urugero rwa deacetylation ya zahabu, ibyuma biremereye cyane kandi birimo ivu rike. Ibice bivamo ubuziranenge bwa hemostatike ni polysaccharide yibinyabuzima byoroshye kuyisukura, ntakintu kibaho, kandi nibikoresho byangirika.
