Wada Test

isishwankathelo

Uvavanyo lweWada, olukwabizwa ngokuba yinkqubo ye-intracarotid amobarbital (IAP), sisixhobo esikhethekileyo sokuxilonga esisetyenziselwa ukuvavanya ukusebenza kwengqondo, ngakumbi ulwimi kunye nenkumbulo. Idla ngokusetyenziswa phambi kotyando lobuchopho ukunyanga ukuxhuzula okanye ezinye iimeko zemithambo-luvo. Olu vavanyo lunceda ukuchonga ukuba yeyiphi i-hemisphere yengqondo elawula ulwimi kunye nokuvavanya umsebenzi wememori, ukuqinisekisa ukuba iindawo ezibalulekileyo zigcinwa ngexesha lotyando.

Yintoni uVavanyo lweWada?

Uvavanyo lweWada okwethutyana luthoba ihemisphere enye yengqondo ngexesha kusetyenziswa ibarbiturate, eqhelekileyo i-amobarbital. Oku kuvumela oogqirha ukuba bajonge ukusebenza kwe-hemisphere echaseneyo. Ngokwenza imisebenzi ngeli xesha lingasebenziyo, oogqirha banokugqiba iindima zelizwe ngalinye kulwimi kunye nokucubungula imemori.

Ukubaluleka koVavanyo lweWada

Uvavanyo lweWada lubalulekile kwizigulana ezenza uqhaqho lobuchopho, ngakumbi abaxhuzula, njengoko:

• Umisela eyona hemisphere yolwimi.
• Uvavanya amandla okukhumbula kwi-hemisphere nganye.
• Ukunciphisa umngcipheko wokuphazamiseka kwengqondo emva kokusebenza ngokukhokela isicwangciso sotyando.

Ukusetyenziswa koVavanyo lweWada

Olu vavanyo lusetyenziselwa ikakhulu:

• Ukuchonga i-hemisphere yolwimi kwizigulane ezine-epilepsy.
• Ukuvavanya umsebenzi wememori ukunciphisa iintsilelo zasemva kokusebenza.
• Ukuvavanya abaviwa botyando lobuchopho, njenge-lobectomy yesikhashana.
• Uphando lwe-lateralization yemisebenzi yobuchopho kwiimeko ezizodwa.

Ukulungiselela uVavanyo

Ukulungiselela kubalulekile kuvavanyo oluyimpumelelo lweWada:

• Xoxa ngembali yakho yonyango kunye namayeza kunye nogqirha wakho.
• Kusenokufuneka uzile ukutya iiyure ezininzi phambi kokuba kwenziwe inkqubo.
• Yazisa umboneleli wakho wezempilo malunga nayo nayiphi na i-allergies, ngakumbi kwi-anesthetics.
• Lungiselela ukuba kubekho umntu oza kukukhapha, njengoko usenokuziva uyozela emva kovavanyo.

Inkqubo yoVavanyo

Uvavanyo lweWada lubandakanya la manyathelo alandelayo:

• Ukufakwa kweCatheter: I-catheter ifakwa kwi-artery kwi-groin okanye ingalo kwaye ikhokelwe kumthambo we-carotid ohambisa igazi kwelinye icala lobuchopho.
• Isitofu sokuthomalalisa: Idosi encinci ye-amobarbital itofwa ukuze ingasebenzi okwethutyana ihemisphere enye.
• Uvavanyo olusebenzayo: Ngoxa i-hemisphere enye ingasebenzi, isigulane senza imisebenzi efana nokuthetha, ukukhumbula izinto, okanye ukuqonda amagama.
• Phinda wenze enye iHemisphere: Inkqubo iphinda iphindwe kwi-hemisphere echaseneyo ukuthelekisa imisebenzi.

Uvavanyo lonke luthatha malunga neeyure ze-1-2, kubandakanywa ukulungiselela kunye nexesha lokubuyisela.

Iziphumo eziqhelekileyo nezingaqhelekanga

Iziphumo Eziqhelekileyo: Ukuchonga ngokucacileyo i-hemisphere elawulayo ukuze kufumaneke ulwimi kunye nobuchule bokukhumbula obusebenzayo.

Iziphumo Ezingaqhelekanga: Iimpawu zokungaqheleki kolwimi okanye iingxaki ezinkulu zenkumbulo zinokutshintsha izicwangciso zotyando.

Izinto ezinempembelelo kwiziphumo zovavanyo

Izinto ezininzi zinokuchaphazela ukuchaneka kovavanyo lweWada, kubandakanya:

• Ukwenzakala kwengqondo kwangaphambili okanye ukungahambi kakuhle.
• Amayeza achaphazela umsebenzi wengqondo.
• Ukuxhalaba okanye ukungabikho kwentsebenziswano ngexesha lovavanyo.
• Ukuhluka kwi-anatomy ye-vascular.
