Iyini ukucwaninga kwe-ultrasound ene-doppler?
Okokuqala, kubalulekile ukusho ukuthi i-doppler ultrasound ekukhulelweni kwenziwa uma kukhona ukusola kokuphulwa kwegazi lokuphuma kwegazi. Kodwa-ke, ukuze kuvinjelwe futhi kuhlolwe ngokushesha ukuphulwa okunjalo njenge-hypoxia ye-fetal, uhlobo olufanayo lokutadisha luyadingeka ukuba lubekwe ngokuphindwe kabili kuyo yonke isikhathi sokuthoma. Ngokuvamile, i-doppler yenziwa emavikini angu-22-24 no-30-34 wokubeletha.
Uma sikhuluma ngalokho okubonisa ngokuqondile i-doppler ultrasound eyenziwa ngesikhathi sokukhulelwa, lokhu kuyimimoya yegazi yomthambo womzimba, ijubane lokugeleza kwegazi kuzo kanye nesilinganiso sokugcwalisa nge-oxygen. Kuyinto ipharamitha yokugcina yokuhlonza enomsebenzi omkhulu kakhulu, kusukela ubonisa ukungabi khona noma ukutholakala kwendlala yomoya emoyeni. Ngaphezu kwalokho, lolu cwaningo luvumela:
- ukucacisa isimo senqubo yesifo senhliziyo yengane ezayo;
- lalela ukushaya kwenhliziyo kwe-fetus;
- lungisa ubukhulu be-lumen yezinto, bese uziqhathanisa namazinga okujwayelekile ngesikhathi esithile.
Ucwaningo ngokwalo alufani neze nokujwayelekile, i-ultrasound. Njengoba kunikezwe leli qiniso, omama abaningi esikhathini esizayo bangase bangazi ukuthi banikezwe i-doppler ultrasound.
Yiziphi izinhlobo zeDoppler ezikhona?
Kumele uqaphele ukuthi lolu cwaningo ngokwalo lungenziwa ngezindlela ezimbili: i-duplex ne-triplex. Muva nje, ngokuvamile kusetshenziswe lesi samuva. Ivumela ukusebenzisa isithombe sombala ukubhalisa ukuhamba kwamangqamuzana egazi abomvu nenombolo yabo yonke. Ngesisekelo sedatha etholakale ngale ndlela, i-apparatus sinquma izinga lokugcwalisa igazi nge-oxygen, okuvumela umuntu ukuba enze isiphetho mayelana nenhlalakahle evamile yengane engakazalwa.
Ucwaningo luqhutshwa kanjani?
Lapho sibhekene nalokho okushiwo i-ultrasound kusho i-doppler, enqunyiwe ngesikhathi sokukhulelwa, ake sicabangele i-algorithm yenqubo ngokwayo.
Ngesikhathi esimisiwe, owesifazane okhulelwe uza ukubonisana kwabesifazane, ekamelweni lokuxilongwa kwe-ultrasound. Ucwaningo ngokwalo lwenziwa endaweni ephezulu.
Esikhathini esiswini, udokotela usebenza ijel ekhethekile, okuthuthukisa ukuxhumana kwenzwa ebusweni besikhumba, futhi ngaleyo ndlela umqhubi wokuqhutshwa kwegagasi. Ukuhambisa inzwa, udokotela uhlola ngokucophelela izitsha, ulinganise ububanzi bawo. Ekupheleni kwenqubo, owesifazane usula i-gel bese evuka ebhedeni.
Ukulungiselela ukuhlolwa okunjalo, njenge-doppler ultrasound ekukhulelwe okwamanje, akukho mfuneko edingekayo, njll. Kungenziwa nganoma yisiphi isikhathi.
Iziphi izimo ezingase zinikezwe i-doppler?
Ngaphezu kwezikhathi ezichazwe ngenhla, isifundo esinjalo singaqokwa futhi singeziwe. Ngokuvamile, lokhu kuyadingeka lapho owesifazane okhulelwe noma owesifazane okhulelwe enezinhlawulo. Kulokho kungenzeka ukuphatha:
- ukwanda kwengcindezi yegazi kwabesifazane abakhulelwe;
- izifo zezingxenye zezinhlelo ze-cardiovascular and urinary;
isimo se-pre-eclampsia; - I-Rhesus-impikiswano;
- ukungahambisani nobukhulu be-fetal ne-age gestational;
- gestosis.
Ngakho-ke, kungashiwo ukuthi i-doppler ultrasound ekukhulelweni kwamanje ibhekisela kuzinyathelo zokuhlola ezivumela ukuqala ukwephulwa ekuqaleni kwesigaba sokuthuthukiswa kwayo. Ngenxa yalokho, odokotela bangasabela ngesikhathi esifanele esimweni samanje futhi bavimbele imiphumela engaphenduki, okuyingozi kakhulu ukufa kwe-fetus.
