Electroencephalography - he aha te mea te reira? Pehea he electroencephalography?

te roro tangata - he hanganga matatini. Ko reira konei e whakakotahi tukanga mahi io haere mai katoa i te rongo, me te ponana hanga tohu whakautu ki te mahi i te mahi ngā.

I te tahi taime tupu te reira e haamata i te roro ki te arā. Whakapae i te aroaro o pāpaka pathological i roto i te wero roro. Tikanga tikanga tātaritanga pērā i ultrasound, MRI, e kore e hoatu e nga wa katoa te pikitia tika o tona mahi. I roto i te wā, pērā i he mea e tika ana ki te kawe i roto i te tango o Tirohia te - te pikitia o te roro. Te tai'oraa i te hanganga o ngaru roro kua electroencephalography kua. He aha te mea te reira?

He aha te mea tenei tikanga?

I raro i electroencephalography matau inaianei he wāhanga ngā o electrophysiology, kua ako te mahi hiko o te roro, me ona wahi takitahi. whakamana ana te inenga e te tikanga o electrodes motuhake tono ki te tumuaki i roto i ngā wāhi. roro Electroencephalography taea ki te hopu i te huringa iti i roto i te mahi o ngā pūtau io, e waiho i roto i te tikanga i runga i ētahi atu tikanga o te tātaritanga o mate neurological.

Ka rite ki te hua o te rēhita o te mahi roro hua he "hopuāhua" ānau ranei - he electroencephalogram. Ko taea ki te tāutu i ngā wāhanga katoa o ngā mahi o te roro, whakakitea nei e etahi ngaru, me te manawataki. Hei rawea, ungeri raraunga o te reta Kariki o te tātai reta (tohatoha i te iti rawa 10 o enei ungeri). Ia o ratou Kei roto te tetahi roangaru characterizing te mahi roro he wahi ngā ona ranei.

History o te rangahau

tīmataria Examination o roro mahi hiko i roto i 1849, ka i whakamatauria ai e reira rite uaua ranei karere muka, nehenehe o hanga ngātere hiko.

I roto i te 1875, i taea e ki te whakarato raraunga inenga o mahi roro electrophysiological i roto i nga kararehe e rua pūtaiao tahi motuhake (Danilevsky i Russia me i Ingarangi Caton) (whakahaere te ako i runga i nga kuri, te räpeti me makimaki).

i whakatakotoria turanga Tirohia te i roto i te tau 1913, ka i taea ki te tuhi i te electroencephalogram tuatahi ki roro o te kuri Vladimir Vladimirovich Vladimir Pravdich-Neminsky. Ia te tuatahi whakaarohia te wā "elektrotserebrogramma".

Hoki te wā tuatahi i roto i te encephalogram tangata i tuhia ai i roto i 1928 i te pūtaiao Tiamana Hans Berger. whakaarohia e ia ki te whakaingoa i te electroencephalogram wā, me te whānui te tikanga e whakamahia ana mai 1934, kua ina kua whakapumautia te wātea o te manawataki o Berger.

Kia pehea te Ko te tukanga?

mahi Rehita o biopotentials o te roro e te mihini i huaina he electroencephalograph.

Tikanga, nga ngā mahi hangaia e te roro, he tino ngoikore, me he uaua ki te whakatika ratou. A i roto i tenei take ki te āwhina mai electroencephalography. He aha te mea whakahuatia reira runga ake. Ki te raraunga moe warea electroencephalograph me taonga, ka haere i roto i te mīhini.

Kua tuhia nga moe, e tika ana ki electrodes tikanga ki runga ki te matenga.

Ka taea te tuhia te tohu hua rānei i te pepa rānei e rongoa i roto i te puka hiko (kite rorohiko) mō te tūhuratanga atu.

hanga te buka iho te ki te faatura ki te pera-ka karanga kore pea. Hoki te manakohia te tikanga reira taringa ranei ranei māhunga tukanga o te wheua pae tino, e kore e nei emit biocurrents.

mahi rēhitatanga te ngātere electrodes whakanohoia ki runga ki te mata matenga i kaupapa motuhake. Ko te 10-20 kaupapa tino whānui.

Taraiwa 10-20

Ko paerewa i te whakanohonga kawehiko tenei kaupapa. E tohaina ratou i runga i te tumuaki i roto i te raupapa e whai ake:

• whakaritea te rārangi tuatahi e e hono i waenganui i te ihu me te inion. Kei te wehea te reira ki te 10 wāhanga rite. E tono aua te kawehiko mua, o muri ki te mua, me te whakamutunga, te tekau, o te aho. eke te tahi atu electrodes e rua ki nga kawehiko tuatahi e rua i te tawhiti rite ki 1/5 o te roa i hanga i te timatanga o te raina. A pae whakanohoia waenganui i waenganui i te kua whakapumautia.
• Conventionally i hanga i tetahi atu raina i waenganui i te meatus māna waho. E tāuta pūoko, e rua i runga i ia taha (i roto i ia tuakoi) me tetahi - i runga i te tihi.
• Whakarara ki te rārangi tau waenga i waenganui i te kaki, me te piriti o te ihu ko tetahi 4 rārangi - matau, me mahue parasagitalnye me te pae tino. tika ratou i roto i nga electrodes eke i runga i te "taringa" o te aho. E ai ki ngā rārangi whakapumautia atu electrodes (5 - ki te parasaggitalnuyu me 3 - i runga i te pae tino).

whakaturia te mata katoa o te matenga kawehiko 21 te.

Tikanga o nga hua

te tikanga whai wāhi electroencephalography rorohiko tuhi i te hua ki te rorohiko ki te waihanga e pā ana ki ia pātengi raraunga manawanui. Ka rite ki te hua, warea o te raraunga hanga oscillations naki o rua momo. Conventionally tuku ki rite te Arepa me te peta ngaru.

Ko te tuatahi kei te nuinga o te wā whakaritea i roto i te āhua o te okiokinga. E āhuatanga ratou e te ngaohiko i te 50 UV me tetahi manawataki - ki runga ki te 10 ia te rua.

hāngai ana Tirohia te moe i runga i te faaotiraa o ngaru peta. I roto i te rerekē ki te āhua ārepa o ngaru, he iti i roto i te rahi ratou, ka puta i roto i te āhua oho. Ratou pā Ko e pā ana ki te 30 mō ia tuarua, me te ngaohiko - tawhio 15-20 mV. Ko te nuinga o ēnei ngaru tohu mahi roro noa i roto i te āhua kia mataara.

hāngai Haumanu Electroencephalography te i runga i te warea o ngaru raraunga. Tetahi ine o ratou (hei tauira, te takanga o te Arepa-poipoi i roto i te āhua kia mataara) tohu te aroaro o te tukanga pathological. Hoki kia meinga ai ngaru encephalogram pathological - Theta-ngaru, tihi poipoi - taui i to ratou natura ranei - takanga o complexes taihemahema.

Āhuatanga o te ako

Titauhia o te rangahau, ko te immobility o te manawanui. A, no te raveraa i te mahi i runga i te whakararu electroencephalogram puta, e ārai atu wetewaehere tika. I roto i te tamariki, he mooni ko te aroaro o taua raweketia.

I tua atu, kua reira ona ake fifi mō te tamariki me te ia electroencephalography. He aha te mea te reira - te whakamārama ki te tamaiti ko reira uaua, a kahore tonu taea ki te whakapati a ia ki te kakahu te potae ki te electrodes. Ka taea e meinga te reira i te tamaiti i te tikanga o te aitua i he pono ki ketia nga hua. Ko Ko te aha kia fakatokanga mātua e hiahia ana koe i roto i tetahi ara hei whakaahuru i te tamaiti ki te kakahu electrodes.

I roto i te ako, te tikanga kawea i roto i whakamātautau ki hyperventilation me photostimulation. tukua ratou ki a koe te tautuhi i te tahi mau kōtītiti i roto i te roro, e kore tuhia e anake.

kihai tūtohutia i mua i te ako, a ētahi wā rāhuitia ki te whakamahi i tetahi raau taero e pā te roro.

Tuhinga mo te tukanga

I roto i ētahi wā, Heoi, tūtohutia ki te kawe i tenei ako?

whakaaturia tikanga Tirohia te te i roto i te wā e whai ake nei:

• Ki te hītori o te syncope māhorahora.
• Hoki te wa roa i reira he pāhoahoa, e kore e urupare ki te rongoā te horomanga.
• I roto i te take o te ofatiraa o te mahara, me te aro.
• disorders Moe me ngā raruraru ki hinga moe me te oho.
• Ki te whakapae koe he backwardness hinengaro i roto i te whanaketanga o ngā tamariki.
• Whanoke me te rohirohi.

I tua atu i te runga ake, electroencephalography taea ki a koe te aroturuki i te hua o te maimoatanga i roto i te tūroro fariiraa i te tahi ahua o therapy tarukino i tua ranei.

taea te tikanga ki te whakatau i te aroaro o mate pērā i haurangi, te pukupuku roro, mate o te kiko roro, disorders arataukai me te supply toto ki te kiko roro.

Electroencephalography i roto i ngā tamariki whakahaere mo te tātaritanga o raro syndrome, ki haaparuparu pararutiki, retardation hinengaro.

Contraindications mo te tukanga

I tahaki, kua tata te tukanga kahore contraindications. Ko te mea anake e taea whakawhāiti i tona whakatinanatanga, ko te aroaro i runga i te mata o te matenga o whara whānui, ngā tukanga hopuhopu whakapeka ranei kaimono postoperative, kihai ora i te wa o te rangahau.

electroencephalography roro whakamana ki tūpato i roto i te tūroro tutu hinengaro rite tiro ratou i roto i te riri e taea arahi i te kōwae. Hoki pehanga o taua tūroro me whakahaere tranquilizers, e tino whakaiti ihirangi mōhiohio o te tukanga me te hua i roto i te raraunga hē.

Taime atoa taea, e pai ki te mahi i te tukanga i roto i te tūroro ki te nui disorders decompensated o te pūnaha Cardiovascular. Ki te te electroencephalograph kawe e wātea ana, ko reira pai ki te whakamahi i te reira, nui atu i tango i te manawanui ki te ako tātaritanga.

Ko te hiahia mo te rangahau

Kia aroha mai, e mohio e kore katoa e reira ko te tikanga o te tātaritanga rite electroencephalography. He aha te mea te reira - e matau ia te maha noa iti o te iwi, i te mea he aha e kore katoa e haere ki te tākuta e pā ana ki tona whakahaere. A i roto i te noa, no te mea he tino tairongo tenei tikanga ka rēhita moe roro. A, no te tika whakahaere ako me te wetemuna hāngai o te raraunga e taea ki te tiki i tata te ki tonu te māramatanga o te taumahinga o te hanganga roro me te oraraa o te tukanga pathological taea.

E ko, ka taea tenei tikanga ki te whakatau i te aroaro o te retardation hinengaro i roto i ngā tamariki taitamariki (ahakoa tino kia hanga e koe utu mo te meka e he ahua rerekē i te hunga i roto i ngā pakeke i te moe, roro i roto i ngā tamariki).

Ahakoa, ki te kahore he maumaui i runga i te wahi o te pūnaha io, i ētahi wā he pai ki te whakahaere i te whakamātautau tātaritanga ki te whakauru obligatory o te Tirohia te, rite taea tukua reira ki te whakatau tīmata huringa i roto i te hanganga roro, a ko reira te tikanga te kī ki te maimoatanga angitu o te mate.
