Ngaba uhlala uziva unesizungu? Makhe sithethe ngovavanyo lweHemodynamic!

Ngaba ngamanye amaxesha uziva unesizungu ngequbuliso, amehlo akho ajika abe luhlaza okwesibhakabhaka, kwaye izinto ezikujikelezileyo zivakala ngathi ziyajikeleza? Okanye uziva ungakhululekanga, ngathi isifuba sakho siyabetha kwaye unengxaki yokuphefumla? Ukuba ezi zinto zenzeka rhoqo, kubaluleke kakhulu ukufumanisa ukuba yintoni ebangela ezo zinto. Kwiimeko ezinjalo, uvavanyo olukhethekileyo ugqirha wakho anokukucebisa lona lubizwa ngokuba yi-"Hemodynamic Test". Namhlanje, siza kuthetha ngale nto ngokweenkcukacha, ngokulula.

Yintoni le 'Hemodynamic Test'?

Ngamafutshane, olu `(Uvavanyo lweHemodynamic)` yindlela yokujonga ukuhamba kwegazi emzimbeni wakho, oko kukuthi, indlela ukuhamba kwegazi okuhamba ngayo, kunye nendlela intliziyo yakho esebenza kakuhle ngayo. Ngamanye amaxesha ikwabizwa ngokuba yi`(uvavanyo lokuthambekela kwehemodynamic)` okanye `(uvavanyo lwe-technetium hemodynamic)`. Oku kungenxa yokuba olu vavanyo lusebenzisa i-isotope ye-radioactive ebizwa ngokuba yi`(technetium)` (siza kuthetha ngale nto kamva). Olu luvavanyo olusebenzisa iteknoloji ebizwa ngokuba yi`(nuclear imaging)`. Musa ukoyika, nangona igama lale nto liyinzululwazi kancinci, wakufunda ngolu vavanyo, uya kuqonda ukuba oku akoyikisi kangako.

Kutheni le nto kwenziwa olu vavanyo? Lufuna ntoni?

Khawuthelekelele, ngequbuliso uyawa uze ufe (okwaziwa ngokuba yi-"syncope") nokuba umi nje ungashukumi. Okanye ugqirha ukrokrela ukuba kukho into engalunganga ngendlela igazi lakho elihamba ngayo, oko kukuthi, ngokujikeleza kwegazi lakho. Kulapho olu vavanyo lwenziwa khona.

Ulwazi oluvela kolu vavanyo lunokunceda ugqirha wakho ukuba afumanise ukuba kutheni uziva ubuthathaka, okanye ingxaki iyintoni na kwinkqubo yakho yokujikeleza kwegazi. Kulapho kuphela apho banokufumanisa khona unyango olulungele wena.

Kukho izizathu ezininzi eziqhelekileyo zokuba umntu angakwazi ukuziva ediniwe:

• Ubungakanani begazi eliya engqondweni yakho ngequbuliso buyehla kancinci.
• Ukwehla ngequbuliso koxinzelelo lwegazi okanye isantya sentliziyo yakho.
• Utshintsho kubungakanani begazi emzimbeni (`umthamo wegazi`) okanye indlela igazi elisasazwa ngayo.

Amaxesha amaninzi, abantu abafa isiqaqa ngolo hlobo banokuba nesifo esithile entliziyweni yabo, kwimithambo-luvo, okanye kwinkqubo ethwala igazi liyise engqondweni. Ngoko ke olu ``(Uvavanyo lweHemodynamic)`` lunceda ekufumaneni ezo zinto.

Ufanele uzilungiselele njani ngaphambi kovavanyo?

Kukho izinto ezimbalwa ekufuneka uzazi kwaye uzilandele ngaphambi kokuba wenze olu vavanyo. Kuphela kukulandela ngokuchanekileyo apho uya kukwazi ukuphumelela uvavanyo ngempumelelo.

• Ukukhulelwa nokuncancisa: Olu vavanyo alunakwenziwa ukuba ukhulelwe okanye uncancisa. Ngoko ke, kunokufuneka wenze uvavanyo lokukhulelwa ukuze ube kwicala elikhuselekileyo.
• Ukutya Nesiselo: Akunakutya okanye ukusela nantoni na kangangeeyure ezine ngaphambi kovavanyo. Akunakutya itshungama okanye itofi. Nangona kunjalo, ukuba unamayeza, ungawasela kunye neengqayi ezimbalwa zamanzi. Buza ugqirha wakho ngale nto kwaye uqinisekise.
• I-Caffeine: Musa ukusela nantoni na ene-caffeine ngomhla wovavanyo. Ayizizo kuphela iti nekofu, kodwa nezinye iziselo ezithambileyo kunye netshokolethi ziqulethe i-caffeine. Kwaneemveliso ezibhalwe "ezingenayo i-caffeine" okanye "ezingenayo i-caffeine" ngamanye amaxesha zinokuba ne-caffeine encinci, ngoko ke ziphephe nezo.
• Kwabo banesifo seswekile: Ukuba unesifo seswekile, cela ukuba ucwangcise uvavanyo lwakho malunga nentsimbi ye-12:30 emva kwemini. Ngale ndlela, ungaba nesidlo sakusasa esilula ngaphambi kwentsimbi ye-8:30 kusasa. Kungcono ukuthetha nogqirha wakho ngale nto.
• Amayeza athile: Musa ukuthatha amayeza okukhupha isisu (iipilisi zamanzi) okanye amayeza okukhupha isisu ( i-laxatives ) ngaphambi kovavanyo. Kungcono ungavuki ngexesha lovavanyo.
• Amanye amayeza: Ungawasela nawaphi na amanye amayeza oqhele ukuwasela njengesiqhelo. Nangona kunjalo, buza ugqirha wakho okanye ikhemisti ukuba kukho nawaphi na amayeza owaselayo ane-caffeine kwaye nokuba akhuselekile na ukuwasela ngosuku lovavanyo. Musa ukuqala okanye ukuyeka nawaphi na amayeza ngaphandle kwengcebiso kagqirha wakho.

Yintoni onokuyilindela ngomhla wovavanyo?

Kufuneka uzinyamekele ezi zinto ngomhla wovavanyo.

• Impahla: Nxiba impahla ekhululekileyo nekhaphukhaphu kunye nezihlangu. Ngexesha lovavanyo, kuya kufuneka unxibe ilokhwe yesibhedlele engagqunywanga ukusuka esinqeni ukuya phezulu.
• Ubucwebe kunye nezinto ezixabisekileyo: Kuphephe ukunxiba ubucwebe obufana namacici, imigexo, imisesane (kuquka nemisesane yomtshato). Musa ukuphatha izinto ezixabisekileyo.
• Izinto onokuzizisa: Qiniseka ukuba uzizisa ezi:
• Ingxelo yakho yakutshanje yezonyango kunye nengxelo yovavanyo lomzimba.
• Ezinye iirekhodi zonyango ezinxulumene neengxaki zakho zempilo.
• Uluhlu lwamayeza onke kunye nezongezo ozithathayo (kuquka nobungakanani obuthathayo).
• Uluhlu lwazo zonke izinto ezikubangela ukuba ungabi namdla.

Olu vavanyo luthatha ixesha elingakanani? Ingaba usezingqondweni?

Olu vavanyo luthatha malunga neeyure ezintathu ukugqitywa, ngoko ke lindela ukuchitha malunga neeyure ezintathu esibhedlele.

Ewe, uza kuhlala uphaphile kulo lonke uvavanyo. Abasebenzi bezonyango baza kukwenza uzive ukhululekile kangangoko. Kodwa kubaluleke kakhulu ukuba uhlale uzolile kwaye uthule kangangoko. Yiyo loo ndlela abanokufumana ngayo imifanekiso emihle necacileyo.

Yintoni esetyenziselwa uvavanyo?

Oogqirha basebenzisa izixhobo ezahlukeneyo kunye neendlela ezahlukeneyo xa besenza olu vavanyo. Makhe sijonge ukuba zeziphi.

• Ukubeka esweni i-EKG (ECG):Iipatches ezincinci nezinamathelayo (ii-electrode) zifakwa esifubeni sakho. Ulwazi oluvela kwezi zinto luthunyelwa kumatshini obizwa ngokuba yi-electrocardiograph (EKG/ECG). Lo matshini urekhoda umsebenzi wombane wentliziyo yakho njengegrafu kwiphepha elihambayo. Unokujonga izinga lentliziyo yakho kunye nesingqisho ngexesha lovavanyo.
• Ukujonga Uxinzelelo Lwegazi: I-cuff yoxinzelelo lwegazi ibekwa engalweni yakho kwaye uxinzelelo lwakho lwegazi lulinganiswa ngamaxesha ahlukeneyo ngexesha lovavanyo.
• I-Hemodynamic Echo: Ngaphambi kokuba uvavanyo luqale (emva kokuba uphumle malunga nemizuzu engama-20), uya kwenziwa i-echocardiogram. Olu vavanyo luthatha malunga nemizuzu engama-20. Luthatha imifanekiso eneenkcukacha zentliziyo yakho. Lukwalinganisa ukuba ingakanani igazi eliphampa intliziyo yakho ngexesha (i-cardiac output). Emva koko, ngexesha lovavanyo, i-cardiac output yakho ilinganiswa kwakhona kwaye ithelekiswe nokufundwa kokuqala.
• Imifanekiso Yezonyango Zenyukliya: Ugqirha usebenzisa ikhamera ekhethekileyo ebizwa ngokuba yikhamera ye-gamma ukuthatha imifanekiso ngexesha lovavanyo. Le khamera ibona imisebe ye-gamma ekhutshwa yi-isotope ye-radioactive (okanye i-tracer). Imifanekiso ethathwe yile khamera inika ugqirha ulwazi oluninzi olubalulekileyo malunga nendlela intliziyo yakho esebenza ngayo kunye nendlela igazi lakho elihamba ngayo. Ingakuxelela nokuba intliziyo yakho ipompa igazi elingakanani kunye nendlela igazi lakho elihamba ngayo ngesantya.

Kwenzeka ntoni ngexesha lovavanyo?

Kulungile, ngoku masibone ukuba kwenzeka ntoni kanye kanye ngexesha lovavanyo.

• Uza kulaliswa etafileni yovavanyo.
• Umboneleli wezempilo, nokuba ngugqirha okanye umongikazi, uza kukuchazela ngokucacileyo ngovavanyo. Ungoyiki ukubuza nayiphi na imibuzo onayo ngelo xesha.
• Uza kunikwa i-IV (i-cannula efana ne-saline drip). Kulapho i-isotope ye-radioactive (okanye i-tracer) ekhankanyiweyo ngaphambili inikwa khona emzimbeni wakho. Le tracer ifakwa nge-IV yakho ngaphambi kokuba kuthathwe iseti nganye yemifanekiso. Ngamanye amaxesha amanye amayeza anokunikwa ngale IV ngexesha lovavanyo.
• Ugqirha uza kubeka ikhamera ye-gamma esifubeni sakho. Kubalulekile ukuba uhlale ungashukumi ngelixa ikhamera ithatha imifanekiso. Ikhamera ingajikeleza nawe.

Kuvakala njani ukwenza uvavanyo?

Usenokungabi nazo naziphi na iimpawu ezikhethekileyo ngexesha lovavanyo. Nangona kunjalo, kuqhelekile ukuba uzive ukhaphukhaphu kancinci, unesicaphucaphu, okanye ukubetha kwentliziyo. Ungakhathazeki ngaloo nto.

Xa i-radioactive agent ifakwa kwi-IV yakho, ungaziva umkhuhlane uphuma engalweni yakho. Ungaziva nencasa yesinyithi emlonyeni wakho kunye nevumba elingaqhelekanga empumlweni yakho. Kodwa ezi mvakalelo azihlali ixesha elide kwaye ziya kuphela emva kwexesha elithile.

Kubaluleke kakhulu ukuba uxelele ugqirha okanye umongikazi yonke into oyivayo ngexesha lovavanyo, nokuba incinci kangakanani na. Banokwenza utshintsho ukuze kube lula kuwe ukuhlala phakathi kweeseti ezimbini zemifanekiso. Ugqirha uza kusebenzisa iimpawu zakho kunye nolwazi oluvela kuvavanyo ukuze abone ukuba yintoni kanye kanye ebangela imeko yakho.

Isebenza kanjani lento?

Imitha ekhutshwa yi-tracer enikwa nge-IV yakho ibonwa yikhamera ye-gamma. Ikhompyutha emva koko isebenzisa olu lwazi ukwenza uthotho lwemifanekiso. Unganikwa iiseti ezintathu zemifanekiso (emibini xa ulele phantsi kunye nomnye xa uhleli phezulu).

Kwenzeka ntoni emva kovavanyo?

Kukho izinto ezimbalwa ekufuneka uzikhumbule nangona uvavanyo luphelile.

• Ukuba ufumanisa naziphi na iimpawu ngexesha lovavanyo, kuya kufuneka uhlale esibhedlele de ezo mpawu ziphele ngokupheleleyo.
• Enye ye-`(tracer)` esetyenzisiweyo kuvavanyo iya kukhutshwa emzimbeni wakho ngomchamo wakho. Eseleyo iya kwahlulwa ngokwemvelo emzimbeni wakho. Ukuba unako, sela amanzi angakumbi. Oko kuya kunceda ukukhupha i-`(tracer)` emzimbeni wakho ngokukhawuleza.
• Emva kovavanyo, uza kunikwa ikhadi oza kuliphatha xa uhamba iveki yonke. (E-US, eli likhadi elithi "iSebe lezoKhuseleko lwaseKhaya laseMelika.") Ngenxa yokuba i-isotope esetyenzisiweyo kuvavanyo yi-"(isotope)", ungenza i-"(alamu)" xa ujonga "(ukhuseleko)" kwiindawo ezifana nezikhululo zeenqwelo-moya.
• Uninzi lwabantu lunokubuyela ekhaya kwangoko emva kovavanyo. Nangona kunjalo, ukuba uneempawu eziqatha, kungcono ukuba nomntu oza kukuyisa ekhaya ngemoto. Ngoko ke bubulumko ukuba nomntu oza kuhamba nawe xa uhamba.

Zithini iingozi kunye neziphumo ebezingalindelekanga zoku?

Njengalo naluphi na uvavanyo lwezonyango, kunokubakho iingxaki ezincinci nalo.

• Usenokuba nemivumbo, ububomvu, okanye ukudumba apho kufakwe khona i-IV. Oku kuqhelekile kwaye kuya kuphela kwiintsuku ezimbalwa. Usenokuziva neentlungu okanye ukungakhululeki xa kufakwa i-IV.
• Loo isotope ye-radioactive ayisiyodayi, ngoko ke ayibangeli ziphumo ebezingalindelekanga ze-allergy.
• Ubungakanani bemitha esetyenzisiweyo kuvavanyo buphantsi kakhulu. Bulingana nobungakanani bemitha efunyanwa ngumzimba wakho xa ufumana i-X-ray yesifuba. Ngoko ke akukho nto ifanele ixhalabe ngayo.

Zinjani iziphumo? Zisixelela ntoni?

Ingxelo efunyanwa ngugqirha wakho iya kuchaza ukuba iziphumo zakho ``ziqhelekile`` okanye ``aziqhelekanga``.

Kwakhona, olu vavanyo lungabonisa izinto ezinje:

• Ngaba une-heart rhythm engaqhelekanga?
• Ngaba kukho utshintsho kuxinzelelo lwegazi?
• Ngaba kukho ingxaki ngentliziyo, efana nesifo semithambo yegazi emithanjeni yegazi, apho ikhoyo, ukuba inzima kangakanani, kwaye yeyiphi imithambo yegazi echaphazelekileyo?
• Ingaba kukho ukwehla kokunikezelwa kwegazi (ischemia)?
• Ingaba kukho ukufa kwezicubu (infarction) ngenxa yokunqongophala kwegazi neoksijini.

Ulwazi oluninzi olubalulekileyo olufana nolu lunokufumaneka kolu vavanyo.

Kuthatha ixesha elingakanani ukwazi iziphumo?

Ngokwesiqhelo kuthatha phakathi kweentsuku ezili-10 ukuya kwezili-14 (oko kukuthi malunga neeveki ezimbini) ukuba ugqirha afumane iziphumo zolu vavanyo.

Ugqirha uza kusebenzisa iziphumo ukwenza isicwangciso sonyango esifanelekileyo kuwe. Kusenokufuneka uqale amayeza amatsha okanye utshintshe amayeza owasebenzisayo ngoku. Ungathunyelwa nakwezinye iingcali.

Ngokusekelwe kwiziphumo zolu vavanyo lwe-"Hemodynamic", ugqirha unokugqiba kwelokuba kufuneka ezinye iimvavanyo.

Okokugqibela, izinto ekufuneka uzikhumbule (Umyalezo Wokuya Ekhaya)

Ngoko ke, ungabona ukuba olu vavanyo lwe-"Hemodynamic" luvavanyo olubaluleke kakhulu olunokukunceda ufumane unobangela wezinto ezinje ngokuquleka rhoqo kunye nobunzima bokuphefumla.

Khumbula, intlungu oza kuyiva ngexesha lovavanyo mhlawumbi kukurhawuzelelwa kancinci xa kufakwa i-IV. Zonke ezinye izinto kulula kuwe ukuzinyamezela.

Iziphumo zolu vavanyo ziya kunceda ugqirha wakho ukuba agqibe ukuba loluphi unyango olukulungeleyo. Ukuba unemibuzo engaphezulu malunga nolu vavanyo, ungathandabuzi ukubuza ugqirha wakho. Hlala usempilweni!
