Kuvamile ukuzizwa wesaba kancane lapho udokotela wakho ekutshela noma othile omaziyo ukuthi udinga ukuhlinzwa kwamehlo . Lo muzwa unamandla kakhulu uma ukhuluma ngesitho esibucayi njengeso. Uma ukhuluma ngokuhlinzwa okunjalo, kungenzeka ukuthi uke wezwa ukuthi kufakwa idayi ekhethekile esweni. Iyini ngempela le dayi? Yenzani? Ingabe iyingozi? Namuhla, sizokhuluma nge-Brilliant Blue G, ikhambi elikhethekile elisetshenziswa ekuhlinzeni kwamehlo, ukuphendula imibuzo eminingi efana nale.
Kalula nje, iyini le Brilliant Blue G?
Cabanga ufuna umfantu omncane kakhulu, ocacile odongeni olumhlophe ngokuphelele. Kunzima ukuwuthola ngamehlo enyama, akunjalo? Kodwa uma uthela amanzi aluhlaza okwesibhakabhaka kulolo donga bese uwusula, umbala oluhlaza okwesibhakabhaka uzongena emfantwini bese uwubona kahle. Yilowo umqondo olula ngemuva kwalokhu.
I-Brilliant Blue G (igama lomkhiqizo: i-TissueBlue) akuyona imithi elapha isifo njengoba sithatha. Iwudayi okhethekile osetshenziswa ngesikhathi sokuhlinzwa. Umsebenzi wayo oyinhloko ukusiza udokotela ohlinzayo ukuthi ahlukanise ngokucacile futhi abone ulwelwesi oluncane nolubonakalayo (ama-membrane) ngaphakathi kweso, hhayi nje iso elivamile, kodwa nalawo amancane kakhulu ukuba angabonwa ngisho nangaphansi kwe-microscope. Lodayi oluhlaza okwesibhakabhaka unamathela kuphela kulezo zilwelwesi ezincane, okwenza zibonakale ziluhlaza okwesibhakabhaka. Khona-ke udokotela angasusa kuphela ulwelwesi oludinga ukususwa ngokunembile, ngaphandle kokulimaza ezinye izingxenye.
Kungani sidinga le dayi? Yiziphi lezo zinhlinzeko?
Le dayi isetshenziswa ikakhulukazi ekuhlinzeni okubandakanya i-retina, ingxenye ebucayi kakhulu yangemuva kweso. I-retina ifana nefilimu ekhamera, lapho izithombe esizibonayo zithunyelwa khona ebuchosheni. Yilapho i-Brilliant Blue G iwusizo khona lapho kwelashwa izimo ezithile ezenzeka ku-retina.
Cabanga ngezinye izimo ezinjengalezi:
- Imbobo Ye-Macular: I- macula yindawo eyinhloko ye-retina esinika umbono ocacile nobukhali. Ngezinye izikhathi kungavela imbobo encane kule macula. Bese, izinto esizibonayo ziba mfushane futhi zinwebeke. Ngesikhathi sokuhlinzwa ukuze kuvalwe lembobo, ulwelwesi oluncane kakhulu (`ulwelwesi olukhawulela ngaphakathi` - ILM) oluyizungezile kumele lususwe. Ngenxa yokuthi lolu lwelwesi luyabonakala, uma kufakwa i-Brilliant Blue G encane kuyo, iphenduka ibe luhlaza okwesibhakabhaka, okwenza kube lula ngodokotela ukuyisusa.
- Ulwelwesi lwe-Epiretinal:Ngezinye izikhathi, ifilimu engafuneki, njengeshidi le-cellophane, ingakhula phezu kwe-retina. Lokhu kubangela ukuthi i-retina izidonsele yona futhi iphazamise umbono. Le dayi isetshenziswa futhi kulokhu kuhlinzwa ukuze kutholakale futhi kususwe leyo filimu engafuneki.
Lokhu kuhlinzwa kuvame ukubizwa ngokuthi ukuhlinzwa kwe-vitrectomy . Kwelapha i-retina ngokususa into efana nejeli (`i-vitreous humor`) engaphakathi kweso.
Kalula nje, le dayi ifana "nesibuko esikhethekile" kudokotela ohlinzayo. Ikusiza ukuthi ubone izinto ngokucacile obungaziboni ngokuvamile.
Uyisebenzisa kanjani le mithi?
Lona akuwona umuthi ongawuthatha ekhaya. Lona umuthi osetshenziswa esibhedlela noma emtholampilo kuphela, egumbini lokuhlinza, futhi usetshenziswa kuphela nguchwepheshe .
Ngesikhathi sokuhlinzwa, udokotela ohlinzayo usebenzisa isirinji encane kakhulu ukufaka inani elincane lalesi sixazululo esweni, kulwelwesi olufunwayo. Ngemizuzwana embalwa, idayi inamathela kulwelwesi. Idayi eningi iyagezwa ngesisombululo esinjenge-saline. Udokotela ohlinzayo manje usengayisusa ngokucophelela ilwelwesi, elibonakala kahle ngombala oluhlaza okwesibhakabhaka.
Kufanele kuqashelwe ngokukhethekile lapho usebenzisa lesi sixazululo ezinganeni. Ngakho-ke uma ingane yakho idinga lolu hlobo lokuhlinzwa, khuluma nodokotela wezingane kanye nodokotela wamehlo ngakho.
Izinto okufanele uzitshele udokotela wakho ngaphambi kokuhlinzwa
Njengoba lokhu kuyinto enikezwa ngesikhathi sokuhlinzwa, kubaluleke kakhulu ukutshela udokotela wakho umlando wakho wezempilo ophelele ngaphambi kokuhlinzwa. Qiniseka ukuthi ubatshela ngalezi zinto ikakhulukazi.
- Ukungezwani komzimba: Qiniseka ukuthi utshela udokotela wakho uma une-allergy ku-Brilliant Blue G noma yimuphi omunye umuthi, ukudla, idayi (isb. idayi yezinwele, idayi yendwangu), noma izithasiselo.
- Ukukhulelwa: Uma ukhulelwe noma uzama ukukhulelwa, yazisa udokotela wakho ngaphambi kokuhlinzwa.
- Uma ungumama oncelisayo: Uma ungumama oncelisayo, khuluma ngalokho futhi.
- Eminye imithi: Nikeza udokotela wakho uhlu oluphelele lwanoma yimiphi imithi, amavithamini, amakhambi, noma izithasiselo ozithathayo. Eminye ingase ihlangane nalesi sixazululo.
Ingabe ikhona imiphumela emibi?
Njenganoma iyiphi inqubo yezokwelapha, kunezingozi kanye nethuba elincane lemiphumela emibi. Kodwa-ke, ngenxa yokuthi isetshenziswa ngemithamo elawulwa kakhulu odokotela, imiphumela emibi emibi ayivamile kakhulu.
Nokho, kubalulekile ukuthi uqaphele lezi zimpawu ezilandelayo. Uma lezi zimpawu zenzeka ngemva kokuhlinzwa, yazisa udokotela wakho ngokushesha.
| Umphumela/izimpawu ezingemuhle | Incazelo nokuthi yini okufanele uyenze |
|---|---|
| Ukusabela Okubi Kakhulu Kokungezwani Nomzimba | Uma uzwa izimpawu ezifana nokuqubuka kwesikhumba, ukulunywa, ukuvuvukala kobuso, izindebe noma ulimi, noma ubunzima bokuphefumula, kungaba yisimo esiphuthumayo. Funa usizo lwezokwelapha ngokushesha. |
| Ukopha esweni | Nakuba kuvamile ukuthi iso libe bomvu ngemva kokuhlinzwa, uma ubona okufiphele, uzwa igazi ligeleza ngaphakathi kweso, noma uma umbono wakho uncipha ngokuzumayo, tshela udokotela wakho ngokushesha. |
| Izinguquko Embonweni | Uma uhlangabezana nanoma yiziphi izimpawu ngemva kokuhlinzwa, njengokungaboni kahle, amabala amnyama antantayo, noma ukukhanya, ungazinaki. Yazisa udokotela wakho ngokushesha. |
Lolu hlu aluhlanganisi yonke imiphumela emibi engaba khona. Uma uhlangabezana nanoma yini engavamile noma esolisayo, kungcono ukubuza udokotela wakho ngayo.
Yini okufanele uyenze uma uphuza ngokweqile ?
Njengoba lokhu kunikezwa ngaphansi kokuqondisa kwezokwelapha esibhedlela, amathuba okusebenzisa ngokweqile cishe ayi-zero. Kodwa-ke, uma usola ukuthi uthathe umuthi omningi kakhulu, xhumana ngokushesha ne-National Poisons Information Centre e-Colombo National Hospital , noma uye e-Emergency Treatment Unit (ETU) yesibhedlela esiseduze.
Umlayezo Wokuya Nawe Ekhaya
- I-Brilliant Blue G akuyona imithi elapha isifo. Iwudayi okhethekile osiza udokotela ukuthi abone kahle ulwelwesi oluthambile ngaphakathi kweso ngesikhathi sokuhlinzwa kwamehlo.
- Lokhu kusetshenziswa kuphela ekuhlinzweni okuyinkimbinkimbi kakhulu kwe-retina .
- Lokhu kunikezwa kuphela egumbini lokuhlinzwa nguchwepheshe. Ngeke ukwazi ukukuthatha uye nakho ekhaya.
- Kubaluleke kakhulu ukutshela udokotela wakho nganoma yikuphi ukungezwani komzimba onakho, eminye imithi oyithathayo, nokuthi ukhulelwe yini ngaphambi kokuhlinzwa.
- Uma uzwa ubuhlungu obungavamile bamehlo, izinguquko embonweni, noma izimpawu ezinkulu zokungezwani komzimba ngemva kokuhlinzwa, yazisa udokotela wakho ngokushesha. Ungesabi, kodwa ungalibali futhi.
