Ukuqhekeka kwekhondom kunye nomonakalo wesisu phakathi kwoluhlu lwezinto ezinokukhathazeka
Ukusetyenziswa kweetyebhethi kungenza ukungena kwezesondo kufumaneke ngakumbi xa kunciphisa kakhulu umngcipheko wokuqhawula ikhondom. Kwiminyaka yakutshanje, nangona kunjalo, bekukho iingcebiso ukuba ezinye iiblue ziyakwazi ukwandisa umngcipheko we-HIV , mhlawumbi ngokunciphisa isakhiwo seekondomu ze-latex okanye kubangela ukuba umonakalo wamaselula afumaneke kwiisisu ezinamaqhekeza ezixhatshaza isisu okanye i-rectum.
Umbuzo wukuthi, ukuba yintoni na yile ya mabango?
Iintlobo zamaLubricants
Izilwanyana ezisekelwe ngamanzi ziye zacetyiswa ukuba zilalwe ngokwesini kunye nolwasemlonyeni wesini, ukusetyenziswa kwayo kunganciphisa izinga lokungaphumeleli kwekhondom ukuya kwi-pesenti ye-3 ukuya kuma-21 ekhulwini okanye xa kungekho nkunkuma isetyenziswa. Ngokwahlukileyo, ii-lubricants-based oil-ezifana neoli ye-oyile, i-oil oil, i-petroleum jelly, okanye i-short-cut (eg, uCrisco) -yaziwa ngokukhawuleza ukuhlaziya i-latex, ngokuphindaphindiweyo emininzi, ukwandisa ukukhutshwa kwekhondom. Ngenxa yesi sizathu sodwa, iiblue oil based based lubricants should always be avoided.
Enye incomo ekhethiweyo, i -lubricants-based-lubricants (polydimethylsiloxane) inamazinga aphezulu e-viscosity kunye nefuthe elincinci kwintembeko ye-latex. Nangona kungenjalo nje ngokuba kufumaneka njengamabhanti asekelwe kumanzi, iiblue lubricants are generally considered as safe though it's limited data clinical to support this, especially in relation to sex .
Kukho i-lubricants-based based lubricants, apho i-glycerine okanye i-propylene glycol ifakwe kwiibluegriji zamanzi eziqhelekileyo. Ezi zixhobo zendalo zisebenza njengama- humectants , ukuthintela ukufudumala kwamanzi ukuqinisekisa ukukhawuleza okuhlala ixesha elide, kwaye ngokuqhelekileyo zibhekwa zikhuselekile ukusetyenziswa.
Iimpembelelo zamaLubriki
Ukususela ngo-2002, kuye kwaba nezifundo eziliqela eziye zaxwayisa ngempembelelo yamabhanti athile kwii-cell ze-epithelial cells ezithintela ubulili kunye ne-rectum.
Olunye uphando luhlolisise ukusetyenziswa kwe- nonoxynol-9 , i-detergent esetyenziswa ngokuqhelekileyo njenge-agementi ye-spermicidal ukuvimba ukutshintshwa kwe-HIV kwabasetyhini.
Uhlolisiso, olubandakanya abasebenzi bezesondo zentengiso eThailand naseAfrika, lubonise ukuba ukusetyenziswa rhoqo kwe-nonoxynol-9 kuye kwaphindaphinda kabini umngcipheko we-HIV, xa kuthelekiswa nabasetyhini kwiqela le-placebo. Umonakalo wobuchopho kunye nesilonda sesisu sasidla ngokuphawulekayo phakathi kwabasebenzisi be-nonoxynol-9.
Imiphumo efana nayo yabonwa xa kuphanda impembelelo ye-nonoxynol-9 kumathambo angama-rectal, baninzi banokuhluthwa izicubu ezinama-rectal kunye nokuphuma kwamagceke kwezinye iimeko. Ngenxa yezi zifundo, i-nonoxynol-9-containing containing lubricants ayinyanzeliswa kubafazi abasengozini enkulu ye-HIV.
Noko ke, iinkxalabo azikhawulelwanga kuphela kwiiblue zine-nonoxynol-9. Ukususela ekupheleni kuka-2006, abaphandi baye bajonga iibisi zokugcoba ezibhekwa njenge- hyperosmolar, oku kuthetha ukuba zithintela utshintsho lwamanzi kwiiseli, ukukhupha amanzi kwaye kubangele ukuba babuthakathake baze bathathaka. Ngokwenza njalo, bayandisa ukwanda kosuleleko ngokuvumela izifo ezithathelwana ngocansi (STIs) indlela echanekileyo ngokusebenzisa izithintelo zamaselula eziza kubaphazamisa.
Olunye uphando olupapashwe kakuhle, oluphuhliswe njengenxalenye ye-UCLA Microbicide Development Programme, lwabonisa ukuba abantu abahlala besetyenziselwa ukugcoba ngesondo ngesilwanyana baba ne- phantyriysia kunye ne- gonorrhea xa beqhathaniswa nabasebenzisi abasebenzisa i-lubricant.
Uninzi lwabasebenzisi (iipesenti ezingama-61) basebenzisa iimveliso ezisekelwe kwamanzi, ngelixa iipesenti ezingama-20 zisebenzisa i-lubricant lubricants, iipesenti ezili-15 zisebenzisa i-lubricants-based based lubricating agent. Kwamaqela angama-421-isigulane, i-229 yayingamadoda kunye ne-192 yabafazi. Uphando, olwenziwe ngo-2012, aluhlolisanga i-HIV okanye nayiphi na i-STI.
Khu seleko lweeLubricants
Olunye uphando, olushicilelwe ngo-2012, lujonge kwiimpembelelo zeeyilethi ezahlukileyo kwiimfucu zamacangca kwaye zigqityiwe, akumangalisi ukuba umngcipheko ohlukeneyo ngumkhiqizo. Ezinye iimveliso zabonisa ukunyuka kwama-hyperosmolarity ngenxa yezinto eziphakamileyo zetyuwa kunye nee-carbohydrate kanti ezinye ziboniswa ukuba yi- iso-osmolar , apho amanqanaba esheyu kunye nezinye izithako ayinanto engathinteli ngayo kwiiseli.
Kule mikhiqizo eyi-14 yophando, ezimbini zokubilisa amanzi, i-iso-osmolar lubricants (i- Good Clean Love kunye ne- PRÉ ) kunye nee-lubricants ezimbini (i- Wet Platinum kunye neComm 2 ). Imveliso ene-chlorhexidine (isetyenziswa ngokutsha kwi-disinfectants kunye ne-cosmetics) yabonakala ibangela umonakalo omkhulu.
Nangona kukho ubungqina besifo sobutyhefu, abaphandi baphetha ukuba akukho bukho ubungqina bokuthi iimfumba zomzimba zandisa ingozi ye-HIV. Ngokwalowo uphando, naluphi na uxhaphazo lwama-epithelial olubangelwa i-lubricant cishe alanele ngokwaneleyo ukuba lunokutshintshwa kwe-HIV. Ukongezelela, kwakungekho utshintsho oluncinane kwiimpawu ezibonakalayo emva kokusetyenziswa kwamanzi.
Akukho zifundo zimbini zibonisa ukuba izitya ziyakunqandwa, njengoko oku kunokubangela ukuba utyhafile olungakumbi kumathisini angama-vaginal / rectal xa ukwandisa ukukhubazeka kwekhondomu. Uphando olongezelelweyo luya kugxininisa ekuboneni iimveliso kunye / okanye izongezo kwiibisi zentsimbi ezingenakubungozi okanye eziyingozi kwimizimba.
