Amakhemikhali e-Breast Implants asetshenziselwa Ukwandisa noma Ukuvuselela Isibeletho
I-silicone i-polymeri enokusetshenziswa okubanzi emikhiqizweni yokunakekela yomuntu kanye nezimila zokuhlinza. Ingatholakala ku-liquide, i-gel, noma i-raber-efana namafomu aqinile. Funda mayelana nezinzuzo zayo nokusetshenziswa kwayo ekufakweni kwebele.
Izinzuzo ze-Silicone
I-silicone yenziwe nge-silicon, i-oxygen, nezinye izinto, ngokuvamile i-carbon ne-hydrogen. I-abiclic inezinzuzo eziningi, kufaka phakathi:
- Ukuzinza ekushiseni okuphezulu
- Ukuphikisana nokuguga
- Ukuphikisana nokukhanya kwelanga
- Ukumelana nomswakama
- Ukumelana nokushisa ngokweqile
Ukusetshenziswa kosizi
Amakhemikhali abonakala cishe ingxenye yengxenye yonke yokwenza, izinwele, isikhumba, nemikhiqizo engaphansi kwe-underarm. Ifomu le-gel le-silicone lisetshenziselwa amabhandeki nokugqoka kanye nesifuba, i-testicle, kanye nezimpande ze-pectoral.
Amakhemikhali asetshenziselwa kakhulu lapho kusetshenzwa izinqubo zezinyosi. Sekusetshenziselwe ukufaka i-vitreous fluid ngemuva kwe-vitrectomy, isebenza njenge-lens intraocular ngesikhathi senqubo ye-cataract, njengama-plug pungal for the eye eye operesheni, futhi ekwelapheni imishini yokutakula.
Amakhemikhali e-Breast Implants
Ukusetshenziswa okwenziwe kakhulu kwe-abicile kufana nokufaka imfuyo yokuhlinzwa kwebele. Izimpande zebele ziyizidakamizwa zezokwelapha ezifakwe ngaphansi kwezicubu zesifuba noma isisipha esifubeni ukuze kwandiswe usayizi webele noma kusize ukuvuselela isifuba. Izimpande zesisu zigcwele u-saline noma i-silicone egcwele igel .
Zombili izinhlobo zezimila zinegobolondo langaphandle le-silicone.
Kulezi ziguli ezine-implantantshi egcwele i-gel egcwele igel, kunconywa ukuthi bathole ukuhlolwa kwe-MRI ukuphulwa okuthulile ngemva kweminyaka emithathu emva kokufakelwa futhi ngemva kweminyaka emibili. Ukuqhekeka okungahleliwe ukuvuza kwe-abicah kusukela ekufakweni kwezicubu ezakhela nxazonke.
Ukufakelwa kwesifuba esiphundukile kungabangela ubuhlungu besisu noma izinguquko ekujuleni kwesifuba.
Izingozi ze-Silicone Izimpande Ze-Breast
Izingozi ze-silicone nezitshalo zesifuba se-saline zifana. Zihlanganisa:
- Isivumelwano se-Capsular
- Ubuhlungu esifubeni
- Ukutheleleka
- Ubungcweti ensikeni
- Ukuvuza noma ukuphulwa kokufakelwa
Ukuze ulungise ezinye zezinkinga, ukuhlinzwa okwengeziwe kungadingeka. I-FDA iphawula ukuthi izimpande zebele azihloselwe ukuhlala isikhathi eside, futhi uma usenesikhathi eside, kuzoba ukuthi kuzodinga ukuhlinzwa ukuze ususe noma uzibeke esikhundleni.
Ingabe Izinsipho Zomzimba Zisibophekile Ziphephile?
I-FDA yakhipha ukuvuselelwa kokuphepha ngo-2011 futhi yathi izimpande ze-gel ze-gel zifakwe ngokuphephile uma zisetshenziswe njengezibhalwe. Bathi kukhona, "akukho ukuhlobana okubonakalayo phakathi kwezimpande ze-gel ezigcwele i-gel nezifo ezixhumene nezifo, umdlavuza webele, noma izinkinga zokuzala." Kodwa bayaqaphela ukuthi badinga izifundo ezinamakhulu nezide ukuze zilawule lokhu.
Ukubuyekezwa okuhlelekile kokuphepha kwezimpande ze-abicala kwebele kungabonisa ukuthi kunezilinganiso ezimbalwa ezilawulwa ngokungahleliwe (i-RCT) ezinamakhono amahle okuhlola. Lokhu kungaphezu kwezinamba eziningi zabesifazane abathola izimpande zebele ze-silicone noma ukuvuselelwa kwebele noma ukukhuliswa kwebele.
Ukubuyekezwa okukodwa ngo-2016 okushicilelwe ku- Annal of Medical Internal kwaphetha ngokuthi, "Ubufakazi buhlala bungavumelani nanoma yikuphi ukuhlangana phakathi kwe-silicone gel implants nemiphumela yesikhathi eside sezempilo. Ubufakazi obungcono buyadingeka ezifundweni ezinkulu ezikhona, ezingasetshenziswa ukucaciswa ukuze zicacise amandla ezinhlangano phakathi kwama-gel implants kanye nemiphumela yezempilo. "
I- Cochrane Database yezibuyekezo ezihleliwe zibukeza ukuthi ngabe kukhona yini umehluko emiphakathini phakathi kokufakelwa kwesifuba esigcwele u-saline kanye ne-silicone ukuvuselelwa kwesifuba futhi atholakala ukuthi abanalo ubufakazi obanele bokuthola iziphetho noma odokotela abahlinzayo ukuba baluleke kahle abesifazane okungcono kakhulu, "Naphezu kwendima ebalulekile yokuvuselelwa kwebele kwabesifazane abanomdlavuza wesifuba, izimpande ezinhle kakhulu zokusebenzisa ekuhlinzekeni okuvuselelayo ziye zafundwa ngokungajwayelekile ezingxenyeni ze-RCTs.
Ngaphezu kwalokho, ikhwalithi yalezi zifundo nobufakazi obuningi abahlinzekayo ngokuyinhloko ayineliseki. "
