Udokotela wakho kungenzeka ukuthi uncome ukuthi wenze i-Evoked Potential Test. Lelo gama lingase lizwakale liyinkimbinkimbi kancane, futhi mhlawumbe liyesabeka kancane, akunjalo? Kodwa empeleni akukho okufanele ukwesabe. Kuyisivivinyo esilula, esingenabuhlungu esivame ukusetshenziselwa ukuthola ulwazi olubalulekile mayelana nokusebenza kwesimiso sethu sezinzwa. Ngakho ake sixoxe ngakho konke ngamazwi alula namuhla.
Kalula nje, iyini le Evoked Potential Test?
Cabanga ngesimiso sethu sezinzwa njengohlelo lwemigwaqo emikhulu egijima emizimbeni yethu yonke. Ulwazi (izibonakaliso zikagesi) luhamba luye phambili naphambili kule migwaqo. Isibonelo, uma ubona okuthile, lolo lwazi luhamba lusuka emehlweni akho luye ebuchosheni bakho ngalezi zindlela zezinzwa. Kunjalo nalapho uzwa okuthile.
I-Evoked Potential Test ilinganisa ukuthi izimpawu zikagesi zihamba ngokushesha kangakanani nokuthi zihamba kahle kangakanani kulezi zindlela zezinzwa. Ilinganisa ukuthi ubuchopho bakho kanye nezinzwa zakho zisabela kanjani ezintweni ezishukumisayo - njengokukukhombisa isithombe, ukuzwa umsindo, noma ukukunikeza ukushaqeka okuncane kakhulu kukagesi.
Lokhu kuhilela ukubeka amapuleti amancane ensimbi (ama-electrode) ekhanda lakho futhi ngezinye izikhathi kwezinye izingxenye zomzimba wakho. Lawa 'abamba' izimpawu zikagesi ezikhiqizwa ezinzwa zakho nasebuchosheni ngenxa yokuvuselelwa.
Yini le test eyifunayo?
Ngezinye izikhathi kungaba nomonakalo emikhondweni yesimiso sezinzwa. Lokhu kungaba okucashile kakhulu ukuthi kungatholakala ngokuhlolwa okuvamile kwezinzwa. Ungase ungabi nazo izimpawu zomonakalo okwamanje.
I-Evoked Potential Test ingabona ngisho nomonakalo ocashile kakhulu njengalona kusenesikhathi .
Odokotela basebenzisa lolu vivinyo kanye nezinye izivivinyo ukuze bathole izimo ezahlukahlukene ezihlobene nesimiso sezinzwa. Lokhu kubaluleke kakhulu ekutholeni izifo ezifana ne -Multiple Sclerosis (MS) .
Ngaphezu kwalokho:
- Thola izimila noma omunye umonakalo emsipheni wokubona.
- Hlola ikhono lokuzwa (lokuzwa noma cha) lezinsana ezincane.
- Uma usola ukuthi kunezimo ezifana nezimila ze-brainstem, qiniseka ukuthi ziyatholakala.
- Gada ukusebenza kwesimiso sezinzwa ngesikhathi sokuhlinzwa okuthile.
Lokhu kuhluke kanjani ku-EEG?
Cishe uke wezwa ngokuhlolwa kwe-EEG. Nakuba kokubili kulinganisa umsebenzi kagesi wobuchopho, kunomehluko phakathi kwalokhu okubili.
- I-EEG (i-Electroencephalogram):Lokhu kwenziwa ngokuqopha amaza kagesi ubuchopho bakho obuwakhiphayo uma buhleli nje lapho, ngaphandle kokushukunyiswa. Kufana nokulalela 'ukusakazwa' kobuchopho bakho.
- Ukuhlolwa Okungenzeka Okuvuswe: Lokhu kulinganisa ukuthi ubuchopho busabela ngokushesha kangakanani futhi kahle kangakanani esikhuthazweni (njengesithombe noma umsindo) esisinikeza ngamabomu . Kufana nokubuza umbuzo bese uhlola impendulo.
Yiziphi izinhlobo eziyinhloko zokuhlolwa okunokwenzeka kwe-Evoked Potential?
Kunezinhlobo ezintathu eziyinhloko zalolu vivinyo. Kuye ngezimpawu zakho nokuthi udokotela wakho ufunani, ungenza eyodwa noma ngaphezulu kwalezi.
| Uhlobo lokuhlolwa | Ungakwenza kanjani? | Yini oyifuna kakhulu? |
|---|---|---|
| 1. Ukuhlolwa kwe-Visual Evoked Potential (VEP) | Ama-electrode anamathele ekhanda lakho futhi ucelwa ukuthi ubheke iphethini efana nebhodi le-chess kusikrini. Uvala iso elilodwa bese ubheka ngelinye, bese ushintsha. | Ibheka umonakalo endleleni yezinzwa ethwala umbono usuka esweni uye ebuchosheni, ikakhulukazi i-optic nerve. Ivame ukusetshenziswa kakhulu ukuxilonga i-MS. |
| 2. Ukuhlolwa kokuzwa (Impendulo Yokuzwa Ye-Brainstem - BAER) | Ama-electrode anamathele ekhanda nasezindlebeni, futhi umsindo 'wokuchofoza' uzwakala ngama-headphone. Indlebe eyodwa ihlolwa ngesikhathi. | Ihlola noma yiziphi izinkinga endleleni yemizwa ethwala umsindo usuka endlebeni uye ebuchosheni kanye nasesiqwini sobuchopho. Ilinganisa umsebenzi we-8th cranial nerve (auditory nerve). |
| 3. Ukuhlolwa kwe-Somatosensory Evoked Potential (SEP) | Ngaphezu kokubeka ama-electrode ekhanda, ama-electrode abekwa nasezihlakaleni nasemadolweni, okuhlinzeka ngesikhuthazo sikagesi esincane kakhulu, esingenabuhlungu. | Ilinganisa ukuthi kuthatha isikhathi esingakanani ukuthi izimpawu zihambe zisuka emithanjeni yomzimba zidlule emgogodleni ziye ebuchosheni. Isiza ekuboneni umonakalo emgogodleni nasebuchosheni. |
Ulungiselela kanjani ukuhlolwa?
Lokhu akudingi ukulungiselela okuningi, kodwa into ebaluleke kakhulu okufanele uyikhumbule ukugeza izinwele zakho kahle ngosuku olwandulela ukuhlolwa bese uzigcina zihlanzekile.
- Ungafaki noma yiluphi uhlobo lwamafutha, ijeli, noma isifutho sezinwele ezinweleni zakho.
- Uma lokhu kuthintwa, ama-electrode ngeke axhumane kahle nesikhumba, okungase kuthinte imiphumela yokuhlolwa.
Udokotela wakho uzokutshela okwengeziwe ngalokhu. Ungesabi ukukubuza uma unemibuzo.
Kuthatha isikhathi esingakanani ukuhlolwa?
Isikhathi singahluka kuye ngohlobo lokuhlolwa okwenziwayo. Ngokuvamile kuthatha imizuzu engama-60 kuya kwengama-90 (ihora nesigamu) . Ungahlala ukhululekile phakathi nalesi sikhathi. Ngezinye izikhathi ungalala ngisho. Ngaphandle kokuvuselelwa okuncane kukagesi okunikezwa ngesikhathi sokuhlolwa kwe-SEP, azikho ubuhlungu obuvela kulezi zivivinyo.
Ithini imiphumela?
Idatha (amagagasi kagesi) evela ekuhlolweni ihlaziywa ngudokotela wezinzwa oqeqeshwe ngokukhethekile noma udokotela wezinzwa bese kulungiswa umbiko. Uma umbiko usutholwe udokotela wakho okwelaphayo, uzokuchazela imiphumela.
Ngokuvamile, imiphumela yalolu vivinyo ayibhekwa yodwa. Ihlanganiswa nezimpawu zakho, imiphumela yokuhlolwa komzimba, kanye nemiphumela yezinye izivivinyo, njenge-MRI scan, ukuze kutholakale ukuxilongwa kokugcina.
Ngakho-ke i-Evoked Potential Test iyisivivinyo esiphephile ngokuphelele futhi esingenabuhlungu esihlinzeka ngolwazi olubaluleke kakhulu mayelana nempilo yesimiso sakho sezinzwa.
Umlayezo Wokuya Nawe Ekhaya
- Ukuhlolwa Okungenzeka Okuvuswe (EP Test) ukuhlolwa okulinganisa isivinini kanye nokusebenza kahle kwezimpawu zikagesi ezihamba ezindleleni zemizwa.
- Lokhu ukuhlolwa okuphephile ngokuphelele, okungenabuhlungu .
- Kunezinhlobo ezahlukene zokuhlolwa kokubona (VEP), ukuzwa (BAER), kanye nokuzwa (SEP).
- Lokhu kubaluleke kakhulu ekuxilongeni izifo ezifana ne-Multiple Sclerosis (MS) kanye nokuthola umonakalo omncane ohlelweni lwezinzwa.
- Geza izinwele zakho kahle ngosuku olwandulela ukuhlolwa futhi ugweme ukufaka amafutha noma ama-gel ezinweleni zakho.
- Udokotela wakho uzokuchazela ngokugcwele imiphumela kanye nezinyathelo ezilandelayo.
