Ake sibone ukuthi igazi ligeleza kanjani emzimbeni wakho. Konke mayelana ne-Doppler Ultrasound!

Namuhla sizokhuluma ngokuhlolwa kwezokwelapha okusha kubantu abaningi, kodwa okubaluleke kakhulu. Kubizwa ngokuthi i-Doppler Ultrasound. Cishe uke wezwa igama, noma mhlawumbe udokotela ukutshelile ukuthi wenze lokhu kuhlolwa. Ngakho-ke, kuyini ngempela? Ake sixoxe ngakho kalula nangendlela enesizotha, njengokungathi ungakhuluma nomngane.

Kuyini i-Doppler Ultrasound? Kalula nje...

Cabanga ngale ndlela: imithambo yegazi emizimbeni yethu ifana nemigwaqo. Igazi lihamba ngale migwaqo njalo, njengezimoto. Ngakho-ke, le Doppler Ultrasound iyi-scan ekhethekile ekwazi ukubona ukuthi igazi lihamba kanjani, okungukuthi, ukuthi igazi lihamba ngakuphi, nokuthi lihamba ngokushesha kangakanani. Lokhu kusebenzisa amaza omsindo esingakwazi ukuwazwa ukuze sithathe izithombe zegazi eligeleza ngaphakathi kwemithambo yegazi. Kulezi zithombe, odokotela bangathola ukuthi kukhona yini inkinga ngenhliziyo yakho noma imithambo yegazi.

Nakuba i-ultrasound ejwayelekile ingathatha izithombe zezitho zomzimba ngaphakathi emzimbeni, ayibonisi ukugeleza kwegazi okuqondile. Yingakho kusetshenziswa indlela ye-Doppler.

Ingabe zikhona izinhlobo ze-Doppler ultrasound? Yebo, ziningana!

Kunezinhlobo ezahlukene ze-Doppler ultrasound, kuye ngokuthi yini oyidingayo emsebenzini wakho. Ake sibone ukuthi yiziphi izinhlobo eziyinhloko:

• I-Color Doppler: Lokhu kuhilela ikhompyutha ekhombisa imibala ehlukene kuye ngokuthi ukugeleza kwegazi kuhamba kanjani. Cabanga ngakho njengokuhamba kwegazi kolunye uhlangothi kuboniswa njengobomvu kanye negazi eliya kolunye uhlangothi kuboniswa njengoluhlaza okwesibhakabhaka. Lokhu kukuvumela ukuthi ubone ngokucacile ukuthi ukugeleza kwegazi kuhamba kanjani.
• I-Spectral Doppler: Lokhu kukhombisa ukugeleza kwegazi ngokuhamba kwesikhathi njengegrafu. Okusho ukuthi, kungasetshenziswa ukubona ukuthi ijubane legazi lishintsha kanjani.
• I-Duplex Ultrasound: Lena inqubo ewusizo kakhulu ngoba ihlanganisa ulwazi oluvela kokubili ezithombeni ze-ultrasound ezivamile kanye ne-Doppler ultrasound. Lokhu kusiza kakhulu ekunqumeni ukuthi imithambo yegazi ibanzi kangakanani nokuthi ngabe kukhona yini ukuvaleka.
• I-Power Doppler: Lokhu kusetshenziselwa ukubona ukuthi kukhona yini ukugeleza kwegazi. Kungabona igazi, ikakhulukazi ezindaweni lapho kuphuma igazi kakhulu khona. Kodwa-ke, akubonisi ukuthi igazi liqonde kuphi. Odokotela bayisebenzisela ukubona ukuthi igazi ligeleza kanjani ngaphakathi kwezitho ezithile zomzimba.
• I-Transcranial Doppler Ultrasound: Lokhu kukhethekile kancane. Kusetshenziselwa ukubheka ukugeleza kwegazi ngaphakathi kwekhanda, emithanjeni yegazi ethwala igazi liye ebuchosheni. Kungasiza ekutholeni izimo ezifana nesifo sohlangothi, noma ezinye izinkinga ngemithambo yegazi ebuchosheni, njengokuphuma kwegazi ngaphansi kwe-subarachnoid (ukopha okuzungeze ubuchopho).

Ubani odinga le Doppler ultrasound?

Manje mhlawumbe ucabanga ukuthi, "Pho ubani ongakudinga lokhu?" Nokho, udokotela angase akucele ukuthi wenze lokhu kuhlolwa kulezi zimo:

• Uma usola ukuthi kukhona okungahambi kahle ngemithambo yegazi esiswini sakho, emilenzeni, noma ezingalweni, thola ngokuqinisekile.
• Ngemva kokuhlinzwa noma ukuthola ukwelashwa okuthile, hlola ukuthi ukujikeleza kwegazi kuleyo ndawo kujwayelekile yini.
• Ngesikhathi sokukhulelwa, hlola ukuthi ukuhamba kwegazi phakathi kukamama nomntwana (ikakhulukazi ngentambo yesisu) kwenzeka kahle yini. Lokhu kubaluleke kakhulu empilweni yomntwana.

Yiziphi izifo ezingatholakala nge-Doppler ultrasound?

Kunezifo nezimo eziningana odokotela bethu abangazithola ngalolu vivinyo. Nazi izibonelo ezimbalwa:

• Ukuvaleka noma ukuncipha kwemithambo yegazi: Ungabona ukuthi imithambo noma imithambo ivalekile noma imincane kakhulu.
• Amahlule egazi: Lokhu kusetshenziselwa ukuthola izinto ezifana nesimo esiyingozi esibizwa ngokuthi "i-Deep Vein Thrombosis (DVT)", okuyihlule legazi emithanjeni ejulile yemilenze.
• Izingozi noma umonakalo emithanjeni yegazi: Hlola ukuthi zikhona yini izingozi ezonakalisile imithambo yegazi.
• Ukuntuleka Kwemithambo Emikhulu Okungalapheki (CVI): Kalula nje, lesi yisimo lapho igazi liqongelela khona emilenzeni esikhundleni sokugeleza liye phezulu, okungukuthi, liye enhliziyweni, ngoba ama-valve emithanjeni emilenzeni awasebenzi kahle.
• Indlela igazi eligeleza ngayo liye ezithweni ezitshaliwe: Ngemva kokuba isitho esinjengezinso, isibindi, noma i-pancreas sitshaliwe, lokhu kubalulekile ukuqinisekisa ukuthi isitho esisha sithola ukugeleza kwegazi okwanele.
• Izinkinga zemithambo yegazi yezinso ezihlobene nomfutho wegazi ophakeme: Ngezinye izikhathi umfutho wegazi ophezulu ungabangelwa izinkinga ngemithambo yegazi ehambisa igazi ezinso. Funa izinto ezinjalo.
• Amathumba: Lokhu kusiza futhi ekuboneni izinto ezinjengalezi.

Isebenza kanjani le Doppler ultrasound? Kuyamangalisa, akunjalo?

Indlela esebenza ngayo ilula kakhulu, kodwa ihlakaniphe kakhulu. Cabanga ngayo ngale ndlela:

1. Umuntu owenza i-scan (masimbize ngokuthi i-sonographer, ungumuntu oqeqeshwe ngokukhethekile ngalokhu) ubeka idivayisi encane, ebizwa ngokuthi i-transducer, esikhumbeni sakho.

2. Le transducer ithumela amaza omsindo avame kakhulu esingakwazi ukuwazwa emzimbeni.

3. Lawa maza omsindo ashaya amangqamuzana egazi ahambayo emithanjeni yegazi emzimbeni bese ebuyela emuva ku-transducer.

4. Okubaluleke kakhulu, ngoba la maseli egazi ayahamba, iphimbo lamaza omsindo abuyayo liyashintsha kancane. Njengoba nje umsindo we-ambulensi egijimayo uyashintsha njengoba usondela futhi uncipha. Lokhu kubizwa ngokuthi "umphumela we-Doppler."

5. Ikhompyutha ihlaziya lolu shintsho lwephimbo ukuze inqume ukuthi igazi lihamba ngesivinini esingakanani nokuthi lihamba ngakuphi.

Kusukela kulolu lwazi, udokotela angathola umbono wezinto ezifana nalezi:

• Kuhamba kanjani ukujikeleza kwegazi lakho? Okusho ukuthi, igazi lihamba ngokushesha kangakanani?
• Ingabe kukhona ukuvimba noma ukuvaleka kokugeleza kwegazi?
• Ingabe igazi liya endaweni engafanele, noma lihlangana endaweni eyodwa?

Kufanele sizilungiselele kanjani ngaphambi kokwenza i-Doppler ultrasound?

Esikhathini esiningi, lokhu akudingi ukulungiselela okuningi. Kodwa-ke, ngezinye izikhathi, kuye ngohlobo lokuskena okwenziwayo kanye nesizathu salokho, kungadingeka wenze izinto ezimbalwa:

• Ukuzila Ukudla: Ngezinye izikhathi, ikakhulukazi uma imithambo yegazi esiswini sakho ihlolwa, ungase ucelwe ukuba uzile ukudla amahora ambalwa ngaphambi kokuhlolwa. Udokotela wakho uzokutshela ngqo ukuthi wenzeni.
• Gwema ukubhema: Kufanele uyeke ukubhema ugwayi noma ukusebenzisa eminye imikhiqizo equkethe i-nicotine (isb., ama-nicotine patches, i-chewing gum) okungenani amahora amabili ngaphambi kokuhlolwa. Lokhu kungenxa yokuthi i-nicotine ivimba imithambo yegazi okwesikhashana, okungathinta imiphumela yokuhlolwa.

Kwenzekani uma kwenziwa i-Doppler ultrasound? Ingabe kuyabuhlungu?

Lena inkinga abantu abaningi abanayo. Kodwa empeleni akuyona ukuhlolwa okubuhlungu nganoma iyiphi indlela. Ngokuvamile kuthatha imizuzu engama-30 kuya kwengama-60.

Nakhu okuvame ukwenzeka:

1. Uzolaliswa etafuleni lokuhlolwa. Ungase ujike ngohlangothi noma ulale phansi, kuye ngokuthi ubuka kuphi.

2. Udokotela we-sonographer uzobe esefaka inani elincane lejeli esikhumbeni sakho, lapho kuzokwenziwa khona ukuskena. Le jeli isiza i-transducer ukuthi ihambe kalula phezu kwesikhumba sakho futhi isize amaza omsindo ukuthi angene kangcono.

3. I-transducer ithumela amaza omsindo angenabuhlungu esikhumbeni sakho emzimbeni wakho. Lawa maza omsindo avame kakhulu kangangokuthi awukwazi ukuwazwa.

4. Uma la maza omsindo eshaya amangqamuzana egazi emzimbeni bese ebuyela emuva, iphimbo lamaza omsindo liyashintsha. Ngezinye izikhathi ungase uzwe umsindo ofana nothi "woosh...woosh..." ovela emshinini we-ultrasound. Lowo umsindo wegazi ligeleza.

5. I-transducer ithola lezi zinguquko. Umshini uqopha lezi zinguquko kumaza omsindo bese uziguqula zibe izithombe noma amagrafu ukuze udokotela azibone.

6. Uma isivivinyo sesiphelile, i-sonographer izosula ijeli ebelifakwe esikhumbeni. Yilokho kuphela!

Ingabe kukhona ingozi kulokhu?

Lezi izindaba ezinhle kakhulu! I-Doppler ultrasound iwukuhlolwa okungahlaseli okungenazo izingozi ezinkulu.

Lokho kusho ukuthi:

• Asikho isidingo sokufaka amadayi anobuthi emzimbeni, njengoba kunjalo ngezinye izivivinyo, njenge-angiogram.
• Akukho ukuchayeka emisebeni, njengasemisebeni ye-X noma i-CT scans.
• Lokhu akubuhlungu futhi akulimazi umzimba. Kuthiwa kuphephile ngisho nakumama okhulelwe.

Sizoyithola nini imiphumela yokuhlolwa?

Ngemva kokuskena, udokotela wakho noma isazi se-radiology (udokotela ochwepheshe ekuxilongeni izifo ngokubuka izithombe zalezi ziskeni) uzobuyekeza imiphumela. Ngokuvamile kuthatha cishe isonto ukuthola imiphumela. Uma usuyitholile, udokotela wakho uzokushayela ucingo ukuze axoxe ngayo. Ngezinye izikhathi, kungase kudingeke ukuhlolwa okwengeziwe ngokusekelwe emiphumeleni.

Yini okufanele ngiyibuze udokotela ngaphambi kokwenza i-Doppler ultrasound?

Kungumqondo omuhle ukubuza udokotela wakho noma yimiphi imibuzo onayo ngaphambi kokuhlolwa okunjalo. Nazi ezinye izinto ongazibuza:

• "Hlobo luni lwe-Doppler ultrasound engizolwenza?"
• "Yiziphi izinto ezithile okudingeka ngizilungiselele ngaphambi kokuba ngifike kulesi sivivinyo?"
• "Ngizoyithola nini imiphumela yokuhlolwa?"
• "Ingabe kuzodingeka ngenze ezinye izivivinyo ngemva kwalokhu?"

Ukwazi izimpendulo zale mibuzo kuzokwenza kube lula ngawe ukubhekana novivinyo.

Lisho ukuthini igama elithi 'Doppler'? Ulwazi oluncane!

Ungase uzibuze ukuthi kungani lokhu kubizwa ngokuthi i-"Doppler" ultrasound. Kuqanjwe ngegama lesazi sefiziksi sekhulu le-19 uChristian Doppler. Wasungula indlela yokukala amaza omsindo avela ezintweni ezihambayo. Lokhu kubizwa ngokuthi "umphumela weDoppler." Yileso simiso esikhulume ngaso ngaphambili, lapho iphimbo lamaza omsindo lishintsha khona njengoba amaseli egazi ehamba.

Okokugcina, izinto okufanele uzikhumbule (Umyalezo Wokuya Ekhaya)

Ngakho-ke, i-Doppler Ultrasound esikhulume ngayo empeleni iyisivivinyo esiphephile kakhulu, esingenabuhlungu, futhi esibaluleke kakhulu. Inganikeza odokotela bethu ulwazi oluningi olubalulekile mayelana nempilo yemithambo yegazi emizimbeni yethu, mayelana nezinkinga zenhliziyo, kanye nokujikeleza kwegazi.

Lolu lwazi lungasetshenziswa ukuxilonga isifo kusenesikhathi, ukuthola ukuthi inkinga iyini ngempela, nokubona ukuthi ukwelashwa kusebenza kangakanani.

Ngakho-ke, uma udokotela ekucela ukuthi wenze lokhu kuhlolwa, asikho isizathu sokwesaba. Kungaba usizo kakhulu empilweni yakho. Uma ufuna ukwazi okwengeziwe, qiniseka ukuthi ukhuluma nodokotela wakho!

I- Doppler ultrasound, ukuskena kwemithambo yegazi, ukujikeleza kwegazi, ukuhlolwa kwamagagasi omsindo, ukuxilongwa kwesifo senhliziyo, amahlule egazi, ukuhlolwa kwezempilo
