I-methylene blue ngexesha lokukhulelwa nokuncancisa
Musa ukuqalisa ukusebenzisa i-methylene blue ngenxa yempilo-ntle, isilonda somlomo, okanye ukulumla ngexesha lokukhulelwa okanye lokuncancisa ngaphandle kwesigqibo sonyango esivela kwiqela lakho lezempilo. Akukho ndlela yokuyisebenzisa ekhaya esele iqinisekisiwe ukuba ikhuselekile kwezi meko. Isigqibo sasesibhedlele sokusebenzisa iyeza lokulwa ityhefu elifakwa emthanjeni sijongene nengxaki eyahlukileyo kuleyo yokukhetha amathontsi athathwa ngomlomo okanye ukuqaba idayi ebeleni.
Umbuzo oluncedo kufuneka ucace: yeyiphi imveliso, isetyenziswa ngayiphi indlela, ngenxa yayiphi imeko, yaye ngubani onokudibana nayo? Ukufunxwa kwayo ngumzimba kamama, ukuchanabeka kwemveku, ukudlulela kwayo ebisini, nokuginya kosana into esengonweni yimibuzo eyahlukileyo.
Ukukhulelwa: isilumkiso sisekelwe entwenini
Ulwazi lwase-US lokumisela inaliti ye-PROVAYBLUE lulumkisa ngomonakalo onokwenzeka kwimveku. Luchaza iziphumo eziyingozi ekukhuleni ezabonwa kwiimpuku nemivundla eyayinikwe i-methylene blue ngomlomo ngexesha lokwakheka kwamalungu omzimba. Ezo mvavanyo kwizilwanyana zibonisa ukuba kukho ingozi; azichazi idosi ekhuselekileyo kubantu xa ithathwa ngomlomo.
Obunye bobungqina obunamandla kakhulu ebantwini bumalunga nenaliti efakwa kwingxowa yamanzi ejikeleze imveku, oko kukuthi, ukufaka inaliti kwingxowa ezaliswe lulwelo ejikeleze imveku. Ngaphambili, oogqirha babesebenzisa idayi ngexesha le-amniocentesis ukuze bahlule iingxowa zamawele. Le ndlela ibeka idayi kwindawo ekuyo imveku yaye mayingabhidaniswa nenaliti efakwa emthanjeni kamama.
Kuphononongo luka-van der Pol noogxa bakhe luka-1992 olwalujonga iimeko zangaphambili, kwenziwa i-amniocentesis kubakhulelweyo abangama-89 ababethwele amawele, kwaza kwasetyenziswa i-methylene blue kuma-86. Kwabali-17 kwabo bakhulelweyo, kwakukho usana olune-jejunal atresia, ukuvaleka okubangelwa kukungabikho okanye kukuvaleka kwenxalenye yethumbu elincinane. Kwabali-15 abachaphazelekayo apho kwakunokuqinisekiswa ukuba leliphi iwele elachanabeka kwidayi, usana olwaluchaphazelekile yayilolo lwaluchanabekile. Oku kwakungumqondiso onzulu wengozi enxulumene naloo ndlela yokusetyenziswa, kungekhona uqikelelo lomngcipheko emva kokutshizwa ngengozi esikhumbeni okanye ukuthatha isongezelelo ngomlomo.
Kutheni unyango olungxamisekileyo lusisigqibo esahlukileyo
Ulwazi lwemveliso yenaliti ye-Proveblue 5 mg/mL luvumela ukusetyenziswa ngexesha lokukhulelwa kuphela xa kuyimfuneko ngokucacileyo, lunika i-methemoglobinemia esongela ubomi njengomzekelo. Kule meko, i-hemoglobin etshintshileyo ayikwazi ukuhambisa ioksijini ngendlela eqhelekileyo. Ingozi yesigulo esinganyangwanga kufuneka iqwalaselwe kwisigqibo kunye neengozi zeli yeza.
Oko kuvunyelwa okukhethekileyo kwezonyango akuthetheleli ukusetyenziswa okukhethwa ngumntu ngenjongo yokwandisa amandla, amandla okucinga, okanye ukuthintela iingxaki. Ukuba kucetyiswa i-methylene blue esibhedlele, xelela iqela ukuba ukhulelwe, ixesha osele ulikhulelwe, nawo onke amayeza okanye izongezelelo ozithathayo. Musa ukulibazisa uhlolo olungxamisekileyo ngoxa uzama ukuzikhethela enye indlela.
Itheyibhile yobungqina ngokwendlela yokusetyenziswa
Le theyibhile yahlula ubungqina obukhoyo kwimibuzo obungenako ukuyiphendula. Yindibaniselwano entsha yemiyalelo yeemveliso, izifundo, nomthombo wolwazi ngokuncancisa ekunxulunyaniswe nazo, eyajongwa ngomhla we-12 Septemba 2026.

| Ukuqatywa engonweni okanye esikhumbeni sebele | Imithombo yezonyango ephononongiweyo ayiqinisekisi indlela ekhuselekileyo yokulumla nge-methylene blue. Intsalela eseluswini izisa umbuzo wokudibana ngqo nayo, ozimeleyo kumbuzo wokudlulela kwayo ebisini. | Musa ukuqaba i-methylene blue ukuze uthintele ukuncanca. Usana lunokudibana nemveliso ngaphandle kokuba iqale yafunxwa ngumzimba kamama. |
Izilonda zomlomo ngexesha lokukhulelwa
Ukuthi “esilondeni kuphela” akuwusombululi umbuzo wokuchanabeka. Imveliso yomlomo idibana nenwebu yomlomo, ixubana namathe, yaye inokuginywa. Izithako zayo nazo zibalulekile: umxube one-borax, ubusi, utywala, okanye ezinye izinto awunakuthathwa njengento efanayo ne-methylene blue yodwa.
Uphononongo lwesigaba 2 apho abathathi-nxaxheba babelwa ngokungacwangciswanga kumaqela, olwajonga ukuhlamba umlomo nge-methylene blue ngenxa yokudumba kwenwebu yomlomo okunxulumene nomhlaza lwaphanda abantu abadala ababefumana ichemotherapy nababeneentlungu eziqhubekayo nangona babefumana unyango oluqhelekileyo. Ukungabandakanyi kwalo abantu abakhulelweyo nabancancisayo sisizathu esicacileyo sokungazisebenzisi iziphumo zalo ukuphendula lo mbuzo. Uphononongo lwalumalunga nemeko yonyango echazwe ngokucacileyo, kungekhona iyeza eliqhelekileyo lezilonda zomlomo ekukhulelweni.
Cela ugqirha wamazinyo, umbelekisi, okanye usokhemesti ukuba achonge unyango olufanelekileyo lwesilonda eso aze ajonge yonke imveliso. Isikhokelo se-NHS sezilonda zomlomo sicebisa uhlolo lwesilonda esihlala ngaphezu kweeveki ezintathu, esahlukileyo kwizilonda zangaphambili, okanye esiya sisiba buhlungu ngakumbi, sibomvu, okanye sophe. Isilonda esiqhubekayo esingaziwayo isizathu saso sifuna ukuhlolwa kunokuba siqhubeke siqatyiwe ngedayi.
Ukuncancisa: ithetha ukuthini imiyalelo yeentsuku ezisibhozo
Ngokuphathelele unyango lwe-PROVAYBLUE olufakwa emthanjeni, imiyalelo yase-US iyalela izigulana ukuba ziyeke ukuncancisa ngexesha lonyango ukuya kutsho kwiintsuku ezisibhozo emva kwalo. Esi sincomo sijongana neziphumo ezibi ezinokuba nzulu, kuquka umonakalo kwizinto zofuzo. Sisikhokelo sokumisela iyeza esikhethekileyo kule mveliso, kungekhona ixesha elivavanyiweyo lakhuseleka kuzo zonke iindidi zemethylene blue okanye ekuyisebenziseni ngokuphindaphindiweyo ngomlomo.
Ingxelo ye-LactMed kaFebruwari 2026 ithi akukho lwazi lufanelekileyo olupapashiweyo ngamanqanaba eli yeza kumama okanye kusana, yaye akukho lwazi lokhuseleko lokusetyenziswa ngomlomo ngexesha lokuncancisa. Ikwaxoxa ngengxelo ka-1933 apho ubisi lungazange lube luhlaza okwesibhakabhaka emva kokuba umama enikwe eli yeza, kucingelwa ukuba lalifakwe emthanjeni. Ukungatshintshi kombala wobisi akunakuqinisekisa ubungakanani bokuchanabeka kosana okanye kungqine ukhuseleko. Into ebonwe ngeliso ayingomlinganiselo wale mihla wokuxinana oneqondo elaziwayo lokubona eyona ntwana incinane ikhoyo.
Ukuba kufuneka unyango lwasesibhedlele, fumana isicwangciso sokondla esibhaliweyo esiquka ixesha lokugqibela lokunikwa iyeza, amalungiselelo okwethutyana okondla, ukukama ubisi xa kufanelekile, nexesha lokuphinda uncancise. Ukuyeka okwethutyana akuthethi ukuba kufuneka kwenziwe isigqibo sokulumla ngokusisigxina. Musa ukubala ixesha lokuphinda uqalise usebenzisa umbala womchamo okanye isixhobo esikwi-intanethi esibala ixesha lokwehla kweyeza emzimbeni ukuya kwisiqingatha.
Ukuliqaba ebeleni ngexesha lokulumla
Musa ukusebenzisa i-methylene blue engonweni okanye ebeleni ukuze wenze umntwana ayeke ukuncanca. Inkxalabo iquka ukungena kwemveliso ngqo emlonyeni womntwana okanye ukudibana kwayo nesikhumba. Nokuba bekunokufunyaniswa ukuba isixa esidlulela ebisini sincinane ngokungabalulekanga, loo ndlela yokuchanabeka ibiya kuhlala ingasonjululwanga.
Xa ukulumla kucwangcisiwe, indlela ye-NHS yokuyeka ukuncancisa isebenzisa ukunciphisa kancinci amaxesha okuncancisa, kunye nokondla okuthatha indawo yoko nokufanele ubudala bomntwana. Oku kukwanciphisa umngcipheko wokugcwala kakhulu kwamabele nokudumba kwebele. Ingcali yokuncancisa inokunceda ilungelelanise olu tshintsho xa ukungakhululeki okanye iingxaki zokondla zikhokelela kwesi sigqibo.
Ukuba ukuchanabeka sele kwenzekile
Musa ukuphinda uchanabeke kuyo ngaphandle kokumiselwa yona ngoxa ufuna iingcebiso. Gcina isikhongozeli uze ubhale ukuxinana kwemveliso, izithako, isixa, indlela esetyenziswe ngayo, ixesha, inqanaba lokukhulelwa okanye ubudala bosana, nokuba usana ludibene ngqo nemveliso. Ezi nkcukacha ziluncedo ngakumbi kunokuthi kuphela ibiyi “dayi encinane eluhlaza okwesibhakabhaka.”
Qhagamshelana neqela elikunyamekelayo ekukhulelweni, usokhemesti, okanye inkonzo yolwazi ngetyhefu ukuze kuhlolwe olo chanabeko ngokukhethekileyo. Ukuba usana lusenokuba luginye imveliso, funa iingcebiso zenkonzo yetyhefu ngokukhawuleza. Ukuphefumla nzima, ukuwa ngesiquphe, ukuxhuzula, okanye ubunzima obukhulu bokuvuka kufuna uncedo olungxamisekileyo.
Yiza noluhlu lwamayeza ngokunjalo. Isikhokelo sokusebenzisana kwe-methylene blue namanye amayeza sichaza ukuba kutheni amayeza achaphazela i-serotonin ebalulekile; umthombo obanzi wolwazi lokhuseleko uchaza ezinye iimeko apho ingafanele isetyenziswe khona. Musa ukuziyeka ngokwakho iziyobisi ozimiselweyo ukuze i-methylene blue ibonakale ingangqubani nazo.
