Makhe sibone indlela igazi elihamba ngayo emzimbeni wakho. Konke malunga neDoppler Ultrasound!

Namhlanje siza kuthetha ngovavanyo lwezonyango olutsha kubantu abaninzi, kodwa olubaluleke kakhulu. Lubizwa ngokuba yiDoppler Ultrasound. Mhlawumbi ukhe waliva eli gama, okanye mhlawumbi ugqirha ukuxelele ukuba wenze olu vavanyo. Ngoko ke, yintoni kanye kanye? Masithethe ngalo ngokulula nangendlela ehloniphekileyo, njengokuba ubuya kuthetha nomhlobo.

Yintoni iDoppler Ultrasound? Ngamafutshane...

Cinga ngale ndlela: imithambo yegazi emizimbeni yethu ifana neendlela. Igazi lihamba kwezi ndlela rhoqo, njengeemoto. Ngoko ke, le Doppler Ultrasound sisikeni esikhethekileyo esinokubona indlela igazi elihamba ngayo, oko kukuthi, indlela elihamba ngayo igazi, kunye nendlela elihamba ngayo ngesantya. Oku kusebenzisa amaza esandi esingawevayo ukuthatha imifanekiso yegazi elihamba ngaphakathi kwemithambo yegazi. Kule mifanekiso, oogqirha banokufumanisa ukuba kukho ingxaki entliziyweni yakho okanye kwimithambo yegazi.

Nangona i-ultrasound eqhelekileyo ingathatha imifanekiso yamalungu angaphakathi emzimbeni, ayibonisi ngqo ukuhamba kwegazi. Yiyo loo nto kusetyenziswa indlela yeDoppler.

Ngaba kukho iintlobo zeDoppler ultrasounds? Ewe, zininzi!

Kukho iintlobo ezahlukeneyo ze-Doppler ultrasound, kuxhomekeke kwinto oyifunayo kumsebenzi wakho. Makhe sibone ukuba zeziphi iintlobo eziphambili:

• I-Colour Doppler: Oku kuquka ikhompyutha ebonisa imibala eyahlukeneyo ngokuxhomekeke kwicala lokuhamba kwegazi. Cinga ngayo njengegazi eliya kwelinye icala liboniswa njengobomvu negazi eliya kwelinye icala liboniswa njengoluhlaza okwesibhakabhaka. Oku kukuvumela ukuba ubone ngokucacileyo icala lokuhamba kwegazi.
• I-Spectral Doppler: Oku kubonisa ukuhamba kwegazi ngokuhamba kwexesha njengegrafu. Oko kukuthi, ingasetyenziselwa ukubona indlela isantya segazi esitshintsha ngayo.
• I-Duplex Ultrasound: Le yinkqubo eluncedo kakhulu kuba idibanisa ulwazi oluvela kwimifanekiso eqhelekileyo ye-ultrasound kunye ne-Doppler ultrasound. Oku kunceda kakhulu ekuqinisekiseni ukuba imithambo yegazi ibanzi kangakanani kwaye ingaba kukho na ukuvaleka.
• I-Power Doppler: Le isetyenziselwa ukubona ukuba kukho ukuhamba kwegazi na. Ingabona igazi, ingakumbi kwiindawo apho kukho ukopha okuninzi khona. Nangona kunjalo, ayibonisi indlela igazi elihamba ngayo. Oogqirha bayisebenzisa ukubona indlela igazi elihamba ngayo ngaphakathi kwamalungu athile omzimba.
• I-Transcranial Doppler Ultrasound: Le yindlela ekhethekileyo. Isetyenziselwa ukujonga ukuhamba kwegazi ngaphakathi entloko, kwimithambo yegazi ethwala igazi ukuya engqondweni. Inokunceda ekufumaneni iimeko ezifana nestroke, okanye ezinye iingxaki ngemithambo yegazi engqondweni, njengokuphuma kwegazi kwi-subarachnoid (ukopha okujikeleze ingqondo).

Ngubani ofuna le Doppler ultrasound?

Ngoku mhlawumbi ucinga, "Ngoko ke ngubani oza kuyidinga le nto?" Kaloku, ugqirha angakucela ukuba wenze olu vavanyo kwezi meko:

• Ukuba ukrokrela ukuba kukho into engalunganga ngemithambo yegazi esiswini sakho, emilenzeni, okanye ezingalweni zakho, fumana ngokuqinisekileyo.
• Emva kotyando oluthile okanye ukufumana unyango oluthile, jonga ukuba ukujikeleza kwegazi kuloo ndawo kuqhelekile na.
• Ngexesha lokukhulelwa, jonga ukuba ukuhamba kwegazi phakathi komama nomntwana (ingakumbi ngentambo yosana) kwenzeka ngokufanelekileyo na. Oku kubaluleke kakhulu kwimpilo yomntwana.

Ziziphi izifo ezinokufunyaniswa nge-Doppler ultrasound?

Kukho izifo neemeko ezininzi ezinokubonwa ngoogqirha bethu ngolu vavanyo. Nazi imizekelo embalwa:

• Ukuvaleka okanye ukuncitshiswa kwemithambo yegazi: Ungabona ukuba imithambo yegazi okanye imithambo yegazi ivalekile okanye incinci kakhulu.
• Amahlwili egazi: Oku kusetyenziswa ukubona izinto ezifana nemeko eyingozi ebizwa ngokuba yi-"Deep Vein Thrombosis (DVT)", eli lihlwili legazi kwimithambo enzulu yemilenze.
• Iingozi okanye umonakalo kwimithambo yegazi: Jonga ukuba kukho naziphi na iingozi ezonakalisile imithambo yegazi.
• Ukungasebenzi kakuhle kwemithambo yegazi (i-CVI): Ngamafutshane, le yimeko apho igazi liqokelelana emilenzeni endaweni yokuba linyuke liye phezulu, oko kukuthi, liye entliziyweni, kuba iivalvu ezisemithanjeni esemilenzeni azisebenzi kakuhle.
• Indlela igazi elihamba ngayo ukuya kwizitho ezifakelweyo: Emva kokuba ilungu elifana nezintso, isibindi, okanye ipancreas lifakelwe, oku kubalulekile ukuqinisekisa ukuba ilungu elitsha lifumana ukuhamba kwegazi okwaneleyo.
• Iingxaki zemithambo yegazi yezintso ezinxulumene noxinzelelo lwegazi: Ngamanye amaxesha uxinzelelo lwegazi oluphezulu lunokubangelwa ziingxaki zemithambo yegazi ehambisa igazi ezintso. Khangela izinto ezinjalo.
• Iithumba: Oku kunceda nasekuchongeni izinto ezinje.

Isebenza njani le Doppler ultrasound? Iyamangalisa, akunjalo?

Indlela esebenza ngayo le nto ilula kakhulu, kodwa ikrelekrele kakhulu. Cinga ngayo ngolu hlobo:

1. Umntu owenza iskeni (masimbize ngokuba yi-sonographer, ngumntu ofumene uqeqesho olukhethekileyo koku) ubeka isixhobo esincinci, esibizwa ngokuba yi-transducer, eluswini lwakho.

2. Le transducer ithumela amaza esandi avakala kakhulu esingawavayo emzimbeni.

3. La maza esandi abetha iiseli zegazi ezihambayo kwimithambo yegazi emzimbeni aze abuyele kwi-transducer.

4. Okubaluleke kakhulu, kuba ezi seli zegazi ziyashukuma, isandi samaza esandi abuyayo siyatshintsha kancinci. Kanye njengesandi se-ambulensi ekhawulezayo siyatshintsha njengoko sisondela kwaye sibuyela umva. Oku kubizwa ngokuba yi-"Doppler effect."

5. Ikhompyutha ihlalutya olu tshintsho kwisandi ukuze ibone ukuba igazi lihamba ngesantya esingakanani kwaye lihamba ngakweliphi icala.

Kolu lwazi, ugqirha unokufumana umbono wezinto ezifana nezi:

• Ihamba njani indlela yakho yokujikeleza kwegazi? Oko kukuthi, igazi lihamba ngesantya esingakanani?
• Ngaba kukho naluphi na uthintelo okanye uthintelo lokuhamba kwegazi?
• Ingaba igazi liya kwicala elingalunganga, okanye lihlangana kwindawo enye?

Sifanele sizilungiselele njani ngaphambi kokwenza i-Doppler ultrasound?

Ixesha elininzi, oku akudingi kulungiswa kakhulu. Nangona kunjalo, ngamanye amaxesha, kuxhomekeke kuhlobo lweskeni eyenziwayo kunye nesizathu sayo, kunokufuneka wenze izinto ezimbalwa:

• Ukuzila Ukutya: Ngamanye amaxesha, ingakumbi ukuba imithambo yegazi esiswini sakho iyahlolwa, unokucelwa ukuba uzile ukutya iiyure ezimbalwa ngaphambi kovavanyo. Ugqirha wakho uza kukuxelela into omawuyenze.
• Kuphephe ukutshaya: Kufuneka uyeke ukutshaya icuba okanye ukusebenzisa ezinye iimveliso ezine-nicotine (umz., ii-nicotine patches, i-chewing gum) ubuncinane iiyure ezimbini ngaphambi kovavanyo. Oku kungenxa yokuba i-nicotine ivimba imithambo yegazi okwethutyana, nto leyo enokuchaphazela iziphumo zovavanyo.

Kwenzeka ntoni xa kwenziwa i-Doppler ultrasound? Ngaba ibuhlungu?

Le yingxaki abantu abaninzi abanayo. Kodwa eneneni ayilovavanyo olubuhlungu nangayiphi na indlela. Idla ngokuthatha malunga nemizuzu engama-30 ukuya kwengama-60.

Nantsi into edla ngokwenzeka:

1. Uza kuphoswa etafileni yovavanyo. Usenokujikwa ngecala okanye ulale phantsi, kuxhomekeke kwikona yokujonga.

2. I-sonographer iza kusebenzisa ijeli encinci eluswini lwakho, apho kuya kwenziwa khona iskeni. Le jeli inceda i-transducer ukuba ihambe lula phezu kolusu lwakho kwaye inceda amaza esandi ukuba angene ngcono.

3. I-transducer ithumela amaza esandi angenabuhlungu eluswini lwakho emzimbeni wakho. La maza esandi asebenza rhoqo kangangokuba awukwazi ukuwava.

4. Xa la maza esandi ebetha iiseli zegazi emzimbeni aze abuyele umva, isandi samaza esandi siyatshintsha. Ngamanye amaxesha unokuva isandi esifana nesithi "woosh...woosh..." sivela kumatshini we-ultrasound. Eso sisandi sokuhamba kwegazi.

5. I-transducer iyazibona ezi nguqu. Umatshini urekhoda ezi nguqu kumaza esandi aze aziguqule zibe yimifanekiso okanye iigrafu ukuze ugqirha azibone.

6. Xa uvavanyo lugqityiwe, i-sonographer iza kuyisula ijeli ebifakwe eluswini. Yiyo leyo!

Ngaba kukho umngcipheko kule nto?

Ezi zezona ndaba zimnandi! I-Doppler ultrasound luvavanyo olungangenisi ntsholongwane olungenazo iingozi ezinkulu.

Oko ikukuthi:

• Akukho mfuneko yokufaka idayi yokwahlulahlula enetyhefu emzimbeni, njengoko kunjalo kwezinye iimvavanyo, ezifana ne-angiogram.
• Akukho kuvezwa kwimitha yelanga, njengakwi-X-ray okanye kwi-CT scans.
• Oku akubuhlungu kwaye akulimazi umzimba. Kuthiwa kukhuselekile nakumama okhulelweyo.

Siza kuzifumana nini iziphumo zovavanyo?

Emva kokuskena, ugqirha wakho okanye ingcali ye-radiologist (ugqirha ochwephesha ekuxilongeni izifo ngokujonga imifanekiso yezi scan) uza kuhlola iziphumo. Ngokuqhelekileyo kuthatha malunga neveki ukufumana iziphumo. Wakuba uzifumene, ugqirha wakho uza kukubiza ukuze axoxe ngazo. Ngamanye amaxesha, kunokufuneka uvavanyo oluthe kratya ngokusekelwe kwiziphumo.
