Yini i-EEG?

I-electroencephalogram (i-EEG) isivivinyo esisetshenziselwa ukuhlola ukusebenza kukagesi ebuchosheni. Amangqamuzana obuchopho ayaxhumana ngomqondo kagesi. I-EEG ingasetshenziselwa ukusiza ukuthola izinkinga ezingaba khona ezihambisana nalo msebenzi.

Amathrekhi e-EEG futhi aqopha amaphethini amagagasi obuchopho. Ama-discs wensimbi ayizicaba abizwa ngama-electrode anamathiselwe ekhanda ngezintambo. Ama-electrode ahlaziya imizwa kagesi ebuchosheni bese ethumela amasiginali kukhompyutha eqopha imiphumela.

Imishayo kagesi ekurekhodweni kwe-EEG ibukeka njengemigqa ye-wavy enezintaba nezigodi. Le migqa ivumela odokotela ukuthi bahlole masisha ukuthi kunamaphethini angajwayelekile yini. Noma ikuphi okungahambi kahle kungaba uphawu lokuquleka noma okunye ukuphazamiseka kobuchopho.

Kungani kwenziwa i-EEG?

I-EEG isetshenziselwa ukuthola izinkinga ekusebenzeni kukagesi kobuchopho okungase kuhlotshaniswe nokuphazamiseka okuthile kobuchopho. Izilinganiso ezinikezwe yi-EEG zisetshenziselwa ukuqinisekisa noma ukukhipha imibandela eyahlukahlukene, kufaka phakathi:

• ukuphazamiseka kokuquleka (okufana nesithuthwane)
• ukulimala ekhanda
• i-encephalitis (ukuvuvukala kobuchopho)
• isimila sobuchopho
• i-encephalopathy (isifo esibangela ukungasebenzi kobuchopho)
• izinkinga zememori
• ukuphazamiseka kokulala
• unhlangothi
• ukuwohloka komqondo

Lapho othile eku-coma, i-EEG ingenziwa ukuthola izinga lomsebenzi wobuchopho. Isivivinyo singasetshenziswa futhi ukuqapha umsebenzi ngesikhathi sokuhlinzwa kobuchopho.

Ingabe zikhona izingozi ezihambisana ne-EEG?

Azikho izingozi ezihambisana ne-EEG. Ukuhlolwa akunabuhlungu futhi kuphephile.

Amanye ama-EEG awafaki amalambu noma ezinye izinto. Uma i-EEG ingakhiqizi noma ikuphi ukungahambi kahle, izengezo ezinjengezibani ze-strobe, noma ukuphefumula okusheshayo kungangezwa ukusiza ukudala noma ikuphi ukungajwayelekile.

Lapho othile enesifo sokuwa noma esinye isifo sokudlikiza, izikhuthazi ezethulwe ngesikhathi sokuhlolwa (njengokukhanya okukhanyayo) zingadala ukuquleka. Uchwepheshe owenza i-EEG uqeqeshelwe ukuphatha ngokuphepha noma isiphi isimo esingavela.

Ngiyilungiselela kanjani i-EEG?

Ngaphambi kokuhlolwa, kufanele uthathe izinyathelo ezilandelayo:

Geza izinwele zakho ngobusuku obandulela i-EEG, futhi ungafaki noma yimiphi imikhiqizo (njengama-sprays noma ama-gel) ezinweleni zakho ngosuku lokuhlolwa.

Buza udokotela wakho ukuthi kufanele uyeke ukuthatha noma imiphi imithi ngaphambi kokuhlolwa. Kufanele futhi wenze uhlu lwemithi yakho bese uyinika uchwepheshe owenza i-EEG.

Gwema ukudla noma ukuphuza noma yini equkethe i-caffeine okungenani amahora ayisishiyagalombili ngaphambi kokuhlolwa.

Udokotela wakho angakucela ukuthi ulale kancane ngangokunokwenzeka ngobusuku obandulela ukuhlolwa uma kufanele ulale ngesikhathi se-EEG. Unganikezwa futhi isidambisi sokukusiza uphumule futhi ulale ngaphambi kokuhlolwa.

Ngemuva kokuthi i-EEG isiphelile, ungaqhubeka nenqubo yakho ejwayelekile. Kodwa-ke, uma unikezwe umuthi wokuthambisa, umuthi uzohlala kusistimu yakho isikhashana. Lokhu kusho ukuthi kuzodingeka uze nomuntu othile ukuze akwazi ukukuyisa ekhaya ngemuva kokuhlolwa. Uzodinga ukuphumula nokugwema ukushayela kuze kuphele umuthi.

Yini engingalindela ngesikhathi se-EEG?

I-EEG ilinganisa imizwa kagesi ebuchosheni bakho ngokusebenzisa ama-electrode amaningana anamathiselwe ekhanda lakho. I-electrode ingumqhubi lapho kungena khona noma kushiye ugesi. Ama-electrode adlulisa imininingwane esuka ebuchosheni bakho iye emshinini olinganisa futhi uqophe imininingwane.

Ochwepheshe abakhethekile baphatha ama-EEG ezibhedlela, emahhovisi odokotela, nasemalabhorethri. Isivivinyo ngokuvamile sithatha imizuzu engama-30 kuye kwengama-60 ukuqeda, futhi sifaka izinyathelo ezilandelayo:

Uzolala ngomhlane esihlalweni esilele noma embhedeni.

Isazi sizolinganisa ikhanda lakho bese simaka ukuthi ungabeka kuphi ama-electrode. Lezi zindawo zikhucululwa ngokhilimu okhethekile osiza ama-electrode ukuthi athole ukufundwa okuseqophelweni eliphezulu.

Uchwepheshe uzofaka isinamathelisi se-gel kuma-electrode ayi-16 kuye kwangama-25, bese enamathisela amabala ekhanda lakho.

Lapho isivivinyo siqala, ama-electrode athumela idatha yomfutho kagesi kusuka ebuchosheni bakho iye kumshini wokuqopha. Lo mshini uguqula izinkanuko zikagesi zibe amaphethini abonakalayo avela esikrinini. Ikhompyutha igcina la maphethini.

Uchwepheshe angakuyalela ukuthi wenze izinto ezithile ngenkathi kuqhubeka ukuhlolwa. Bangakucela ukuthi ulale unganyakazi, uvale amehlo akho, uphefumule kakhulu, noma ubuke izinto ezishukumisayo (ezifana nelambu elikhanyayo noma isithombe).

Ngemuva kokuthi ukuhlolwa kuqediwe, uchwepheshe uzosusa ama-electrode ekhanda lakho.

Ngesikhathi sokuhlolwa, ugesi omncane kakhulu udlula phakathi kwama-electrode nesikhumba sakho, ngakho-ke uzozizwa ungakhululekile neze.

Kwezinye izimo, umuntu angathola i-EEG yamahora angama-24. Lawa ma-EEG asebenzisa ividiyo ukuthatha umsebenzi wokubamba. I-EEG ingakhombisa ukungajwayelekile noma ngabe ukuquleka kungenzeki ngesikhathi sokuhlolwa. Kodwa-ke, akuhlali kukhombisa ukungajwayelekile okwedlule okuhlobene nokubanjwa.

Isho ukuthini imiphumela yokuhlolwa kwe-EEG?

Udokotela wezinzwa (umuntu ogxile ekuphazamisekeni kwesistimu yezinzwa) uhumusha okuqoshiwe okuvela ku-EEG bese ethumela imiphumela kudokotela wakho. Udokotela wakho angahlela i-aphoyintimenti yokuyobheka imiphumela yokuhlolwa kwakho.

Imiphumela ejwayelekile

Umsebenzi kagesi ebuchosheni uvela ku-EEG njengephethini yamagagasi. Amazinga ahlukene okwazi, njengokulala nokuvuka, anezinga elithile lamagagasi ngomzuzwana athathwa njengokujwayelekile. Isibonelo, amaphethini amagagasi ahamba ngokushesha lapho uvukile kunalapho ulele. I-EEG izokhombisa ukuthi imvamisa yamagagasi noma amaphethini ajwayelekile yini. Umsebenzi ojwayelekile ngokujwayelekile usho ukuthi awunakho ukuphazamiseka kobuchopho.

Imiphumela engajwayelekile

Imiphumela engajwayelekile ye-EEG ingabangelwa:

• isithuthwane noma esinye isifo sokuquleka
• ukopha okungavamile noma ukopha
• ukuphazamiseka kokulala
• i-encephalitis (ukuvuvukala kobuchopho)
• isimila
• izicubu ezifile ngenxa yokuvaleka kokugeleza kwegazi
• migraines
• ukusetshenziswa kabi kotshwala noma izidakamizwa
• ukulimala ekhanda

Kubaluleke kakhulu ukuxoxa ngemiphumela yakho yokuhlolwa nodokotela wakho. Ngaphambi kokubuyekeza imiphumela, kungasiza ukubhala phansi noma yimiphi imibuzo ongafuna ukuyibuza. Qiniseka ukuthi uyakhuluma uma kukhona okuthile ngemiphumela yakho ongakuqondi.
