I-BAER (i-Brainstem Auditory Respoked Response) iqhutshwa rhoqo xa umntwana wakho ehlulekile ukuvavanya i-otoacoustic emissions (OAE) ngaphandle kokuba umntwana wakho azalwe ngaphambi kwesikhathi. Olu vavanyo lusetyenziswa kwakhona ukuba kukho naziphi na izizathu ukuba iimvavanyo ezivakalayo eziqhelekileyo azikwazi ukuzenza. Iintsholongwane zentloko kunye nee-earphone ukuvavanya intshontsho yentsana yakho yokuhlola, i- cochlear kunye neendlela zokuvalelwa kwingqondo.
Phantse abantwana aba-3 kwabakwi-1,000 bazalwa ngokukhulu kunomlinganiselo ophantsi wokuvalelwa kweendlebe. Ukulahleka kokuphulaphula , ukuba kungabonakali kwaye kulungiswe kusenokwenzeka, kunokukhokelela ekulibazisekeni kokuphuhliswa kwaye kufuna iqondo eliphezulu lokunyanga. Kuqhutyelwa rhoqo endaweni yokuvavanya ukuvavanya ukuziphatha kwabangakwazi ukusebenzisana novavanyo oluvakalayo lokuvavanya (umzekelo, iintsana, abanokulibaziseka okuphuhliswayo, njl.), Kodwa kusenokusetyenziswa ukufumanisa ukulahlekelwa kwindlebe.
Amanye Amagama Ukuhlolwa kwe-BAER: Impendulo ye-Brainstem Response (ABR), i-Screening Auditory Brainstem Response (SABR), iMpendulo ye-Brainstem Response (AABR), i-Auditory Evoked Potential (AEP), i-Brainstem Auditory evoked Potential (BAEP)
Ukuhlolwa kwe-BAER kwenziwa njani?
Uvavanyo lwe-BAER alubuhlungu kwaye luyakwenziwa ngelixa umntwana wakho elele okanye ephumle amehlo abo avaliwe. Ukuhamba kunye nokuxhatshazwa kunokubangela ukungaqhelekanga kovavanyo, ngoko ke ukuba umntwana wakho akakwazi ukuphumla, baya kudityaniswa.
- Iimvamisa (i-electrodes) zifakwe ebunzini lomntu, i-scalp, kunye ne-earlobes
- Iindlebe ezincinane okanye i-headphones zifakwa ngaphakathi kwindlebe nganye
- Emva kokuba zonke izixhobo zenzeke uchungechunge lweefowuni, ukubetha, kunye nezinye izandi zidlalwa.
- Ukusabela kwengqondo kwezi zandi kubhalwe (ngokusebenzisa i-electrodes)
Ngexesha lokuvavanya kwe-BAER, akukho mpendulo evela kumntwana wakho kuyimfuneko.
Iimvumi ezifakwe entloko zibona umsebenzi wengqondo ngelixa izandi zidlalwa ezindlebeni zomntwana ngeendlebe. Uvavanyo aluyi kuqwalasela ukukwazi ukuva amanqanaba ahlukeneyo omsindo, njengetoni enye kunye nomthamo omnye.
Ukuvavanya Kuhlolwe njani
Iinjongo zentloko zivelisa igrafu eneendlela ezi-7 ezinkulu zokutshintsha njengokuba imisindo edlalwa kwi-earphone ihamba ukusuka endlebeni ukuya kwingqondo. I-audiologist ihlolisisa iziphumo ngokuvavanya i- latency (umgama okanye ixesha phakathi kweentaba zamagagasi) kunye nobukhulu (ukuphakama kwamaza). Nangona kukho amaza angama-7, amaza kuphela i-III, i-V ayimfuneko ekuqaliseni nasiphi na into engafanelekanga. I-audiologist izakukubonelela nge- pass or fail result for the test BAER.
Ngaba Kufuneka Yenziwe?
I-BAER iqhutshwa rhoqo kwiintsana ezisandul 'ukuzalwa ukuba zikhumbule ukuva kwazo kwaye zihlala zisetyenziswa ngokubambisana novavanyo lwe- OAE . Ukuba akukho zixazululo zokuthunyelwa komntwana wakho, i-OAE iya kwenziwa kwaye uvavanyo lwe-BAER kuphela xa i-OAE ihlulekile. Ukuba umntwana wakho wazalwa ngaphambi kokudala okanye enomngcipheko wokukhubazeka kwe-neurological, uvavanyo lwe-BAER luya kwenziwa kuqala. Ukuba umntwana wakho akadluli uvavanyo lwe-BAER akuthethi ukuba abayizithulu okanye banokulahlekelwa yintlawulo engapheliyo; kuhlolwa ngakumbi.
Esinye isizathu esiqhelekileyo sokuvavanya kwe-BAER kuya kwenziwa xa unomntwana onokulibaziseka okuphuhliswayo ongenakufumana ezinye iindlela zokuvavanya ezenzelwe ukuhlola ukuva.
Izizathu eziqhelekileyo zokungadlulanga i-BAER ziquka:
Izizathu ezingaqhelekanga:
- IAresia
- Uphicothi-zincwadi
- Vestibular schwannoma
- Isisu se-Acoustic
- Isisu sobumba
Kubalulekile ukuqaphela ukuba nangona umntwana wakho edlula ukuhlolwa kwe-BAER, basenokukwazi ukuphuhlisa iingxaki zokuva emva koko ebomini.
