Uvavanyo lwe-Methylene eluhlaza okwesibhakabhaka

Uvavanyo lwe-methylene eluhlaza okwesibhakabhaka luvavanyo lokufumanisa uhlobo okanye ukunyanga i-methemoglobinemia, isifo segazi.

Umboneleli wezempilo usonga ibhendi eqinileyo okanye uxinzelelo lwegazi kwikofu yakho engaphezulu. Uxinzelelo lubangela imithambo engezantsi kwendawo igcwalise ngegazi.

Ingalo icocwa ngombulali wentsholongwane (isinqanda-kubola). Inaliti ibekwa emthanjeni wakho, ihlala ikufutshane nengqiniba okanye umva wesandla. Umbhobho omncinci obizwa ngokuba yi-catheter, ufakwa emthanjeni. (Oku kunokubizwa ngokuba yi-IV, oko kuthetha ukuba kungena ngaphakathi). Ngelixa ityhubhu ihlala endaweni yayo, inaliti kunye neetourniquet ziyasuswa.

Umgubo oluhlaza omnyama obizwa ngokuba yimethylene luhlaza uhamba ngombhobho ungene kumthambo wakho. Umboneleli ujonga indlela umgubo oguqula ngayo into esegazini ebizwa ngokuba yi-methemoglobin kwi-hemoglobin yesiqhelo.

Akukho lungiselelo lukhethekileyo luyafuneka kolu vavanyo.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukutyumza kancinci. Oku kuya kuhamba kungekudala.

Zininzi iintlobo zeeproteni ezithwala ioksijini egazini. Omnye wabo yi-methemoglobin. Inqanaba eliqhelekileyo le-methemoglobin egazini lihlala li-1%. Ukuba inqanaba liphezulu, ungagula kuba iproteni ayiphathi ioksijini. Oku kunokwenza igazi lakho libonakale limdaka endaweni ebomvu.

I-Methemoglobinemia inezizathu ezininzi, uninzi lwazo yimfuza (ingxaki ngamajelo akho). Olu vavanyo lusetyenziselwa ukuxelela umahluko phakathi kwe-methemoglobinemia ebangelwa kukungabikho kweprotein ebizwa ngokuba yi-cytochrome b5 reductase kunye nezinye iintlobo ezidluliswa kwiintsapho (ezizuzwe njengelifa). Ugqirha wakho uza kusebenzisa iziphumo zolu vavanyo ukunceda ukumisela unyango lwakho.

Ngokwesiqhelo, imethylene eluhlaza okwesibhakabhaka yehlisa ngokukhawuleza inqanaba le-methemoglobin egazini.

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nomboneleli wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Unokuba nefom enqabileyo ye-methemoglobinemia ukuba olu vavanyo alulinciphisi kakhulu inqanaba legazi le-methemoglobin.

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukufaka i-IV kunokuba nzima kuwe okanye emntwaneni wakho kunakwabanye abantu.

Eminye imingcipheko enxulumene nolu hlobo lovavanyo lwegazi incinci, kodwa inokubandakanya:

• Ukopha kakhulu
• Ukufa isiqaqa okanye ukuziva ungenantloko
• Ukugqobhoza okuninzi ukufumana imithambo
• I-Hematoma (igazi eliqokelelwa phantsi kolusu lubangela ukutyumka)
• Usulelo (umngcipheko omncinci ngalo naliphi na ixesha ulusu lophukile, kodwa amathuba osulelo anyusa ixesha elide i-IV ihlala emthanjeni)
