Abacwaningi bahlolisise izilinganiso ezilindelekile zamaphuzu athile ekukhulelweni kokuqala, ngakho-ke ukuskena kwe-ultrasound yokuqala kunganika udokotela ulwazi olubalulekile.
Ukusetshenziswa okuvamile kwe-ultrasound ekukhulelweni kokuqala ukubala iminyaka yobudala . Ngenxa yalokhu, i-ultrasound ibhekwa njengendlela enembile kakhulu yokuthandana nokukhulelwa. Ngokukhulelwa okujwayelekile, imiphumela ye-ultrasound inganikeza ukulinganisa kweminyaka yobudala kuze kube ezinsukwini ezinhlanu kuya kweziyisikhombisa zokunemba.
Uma owesifazane ephethe izimpawu zokuphumula , udokotela angase acele eyodwa noma ngaphezulu ama-ultrasounds ukuthi anqume ukuthi ukukhulelwa kuyasebenza kanjani.
Indlela Ukukhulelwa Kwangaphambi Kokuqala Kusebenza Kanjani
Ku-trimester yokuqala, odokotela ngokuvamile basebenzisa i-transvaginal kune-ultrasound yesisu ukuze baqoqe ulwazi mayelana nokukhulelwa. I-ultrasound ye-transvaginal inikeza ukwaziswa okunembile kakhulu ekukhulelweni kokuqala, njengoba kunikezwa ukuthi isikhumba sokuqala sokukhulelwa kanye nesibalo se-fetal sincane kakhulu kuleli phuzu futhi i-ultrasound yangasese ingasondelana nokukhulelwa okukhulayo.
E-ultrasound yangaphandle, udokotela noma ochwepheshe ufaka isitebe esincane emgodini ukuze athathe uchungechunge lwezilinganiso, kufaka phakathi ubukhulu besigqoko sokugcoba, ubukhulu besikhwama se-yolk, ubude be-fetal pole, nenhliziyo isilinganiso.
E-ultrasound yesisu, owesifazane uzocelwa ukuthi afike esithini ngesisindo esigcwele, ngoba lezi zikhundla isibeletho ngendlela eyenza kube lula ukuthola izilinganiso. Udokotela noma ochwepheshe usakaza igesi phezu kwesisu esingaphansi bese esebenzisa i-transceiver ukuthatha izilinganiso ezivela ezingxenyeni eziningi.
Imiphumela elindelekile ye-Ultrasound Ngeviki le-Early pregnancy
Lawa angamaphesenti lapho amaphuzu athile okuthuthukiswa kokukhulelwa okuqala atholakele yi-ultrasound transvaginal. Ngokuvamile, i-ultrasound yesisu ayinandaba kakhulu futhi angeke ithole lezi zenzakalo ezinkulu kuze kufike ngesonto noma kamuva ekukhulelweni.
Khumbula futhi ukuthi noma yikuphi ukungaqiniseki mayelana nosuku lokuvota kungathinta lokho i-ultrasound izobonisa nganoma yisiphi isikhathi ekukhulelwe kwangaphambi kwesikhathi.
Okwenza Imiphumela Yasekuqaleni Ye-ultrasound ingaba yinto ecacile yokunquma ukushada
Imiphumela ye-ultrasound iqhathaniswa nalokho okulindelwe iminyaka yobudala bokukhulelwa. Iminyaka yobudala ibalwa inani lamasonto kusukela esikhathini sokugcina sokuya esikhathini; Kodwa-ke, le ndlela ngokuvamile ithatha umjikelezo wosuku lwezinsuku ezingu-28 nge-ovulation eyenzeka ngosuku lweshumi nane. Abesifazane abaningi banemijikelezo emifushane noma emide futhi abavuthanga ngosuku lweshumi nane - futhi lokhu kungathinta lokho i-ultrasound okufanele ibonise ekuthuthukisweni kokukhulelwa.
Isibonelo, uma owesifazane enezinsuku ezingu-35 zokuhamba esikhathini, cishe u-ovulates azungeze usuku lwesi-21 lomjikelezo wakhe wokuya esikhathini (ngoba i-ovulation ngokuvamile ivela emasontweni amabili ngaphambi kokuqala kwesikhathi sokuya esikhathini). Uma lo wesifazane ekhulelwe futhi eseshaywa i-ultrasound amasonto ayisithupha kusukela ekupheleni kwesikhathi sokugcina esikhathini, ukuvama kwakhe ukukhulelwa kungalinganisa iminyaka yobudala bezinsuku eziyisihlanu, ngoba uhlelo lokuthandana nobudala bezinsuku zokuzalwa luqala ukuthi uzobe esevezile ngesonto ngaphambi kokuba wenza. Uma lona wesifazane engazi ukuthi uke wavula ngosuku lwama-21 womjikelezo wakhe, angase akhathazeke ngokungadingekile ukuthi wayenomkhuhlane wokubeletha uma ephethe i-ultrasound yokuqala eyabonisa amasonto amahlanu kuphela okuthuthukiswa ekukhuleleni kwakhe lapho esebuchwepheshe "amasonto ayisithupha ukhulelwe. "
Ngokufanayo, akubona wonke umuntu ohamba ngokucophelela ukuqala kwesikhathi sokuya esikhathini. Uma owesifazane engakwazi ukukhumbula lapho isikhathi sakhe sokuya esikhathini siqala futhi aqagela usuku olungalungile, noma ngabe unomjikelezo ojwayelekile wezinsuku ezingu-28, lokhu kungashintsha imiphumela ekulindeleke yokuskena kwe-ultrasound.
Ekukhulelweni kokuqala, isikhwama sokugaya nesisu sishintsha kakhulu nsuku zonke, ngakho-ke ukuphuma ngisho nezinsuku ezimbalwa zokuphola kungenza umehluko ukuthi noma ngabe i-ultrasound kufanele ibone ukushaya kwenhliziyo.
Isikhumba esingenalutho se-Gestational / Ayikho i-Fetal Heartbeat / Ayikho i-Fetal Pole
Ngezinye izikhathi i-ultrasound izonikeza imiphumela engaqinisekile. Isibonelo, uma owesifazane ekhulelwe amasonto ayisikhombisa futhi i-ultrasound ingabonakali ukushaya kwenhliziyo kwengane, udokotela angase alawule enye i-ultrasound ngesonto. Ukukhulelwa kungase kube yinto evamile kepha kuphele izinsuku ezimbalwa ekuthandeni-noma ukuphola kungase kube nenembile kodwa isikhathi sisengaphakathi kwephutha lesiphambeko lapho ukushaya kwenhliziyo kutholakala kwi-ultrasound.
Ngokufanayo, uma i-ultrasound ibonisa isikhwama esingenalutho sokugcoba, lokhu kungase kube ukutholakala okuvamile uma ukukhulelwa kusenesikhathi. Izingane ezisathuthuka zincane kakhulu ukuthi zingabonwa kwi-ultrasound kuze kube amasonto amahlanu okubeletha. Kulolu daba, udokotela angakhetha ukuphinda i-ultrasound ngosuku oluthile.
Kuzo zonke lezi zimo, imiphumela ye-ultrasound ingase ikhombise ukukhulelwa kwesisu noma ukukhulelwa kungase kube okuvamile. Uma i-ultrasound esilandelayo ibonisa ukuthi ukukhulelwa kuye kwaqhubeka kuthuthukiswa, imiphumela yangaphambilini ingabhekwa ezinkingeni zokuthandana. Uma i-ultrasound esilandelayo isabonisa ukuthuthukiswa okungavamile, udokotela angakwazi ukuhlola ngokucophelela ukukhulelwa kwesisu-kodwa udokotela akakwazi ukucacisa umphumela esekelwe kuphela ekukhunjweni kokuqala kwe-ultrasound kuthathwa ezimweni eziningi.
Ukulinda i-ultrasound ephindaphindiwe kungaba nzima kakhulu ngokomzwelo, kodwa kungadingeka ukuze ugweme ukuhlukumeza ngaphandle uma olunye ulwazi lukhona ukusiza udokotela ukuhumusha imiphumela ye-ultrasound.
Yeka ukuthi imiphumela ye-hCG noma olunye ulwazi olungasiza kanjani ukuhumusha kwe-Ultrasound
Uma kunombuzo wokuthi ngabe owesifazane unesifo sokukhulelwa ngokweqile ngokususelwa kumshini we-ultrasound, isenzo esivamile sokuthi udokotela uzokhipha enye i-ultrasound ezinsukwini ezimbalwa noma ngesonto.
Ngezinye izikhathi, noma kunjalo, ukutholakala kolunye ulwazi lokuxilonga kungasiza udokotela ukuba ahumushe imiphumela ye-ultrasound ngisho noma kuneskena esisodwa se-ultrasound. Isibonelo, uma owesifazane ehlolwe ukukhulelwa okuhle ngosuku lokuphuluka kwakhe okulandelwayo okulandelwa ukuqinisekiswa ngemiphumela yokuhlolwa kwegazi ye-hCG kanye ne-ultrasound emasontweni amane kamuva kubonisa ukukhulelwa emasontweni amahlanu nje kuphela ekuguleni, udokotela angaphetha ngokuthi lo wesifazane ube ukukhulelwa kwesisu okungabanjwanga-ngoba ukuhlolwa kokukhulelwa kwangenyanga inyanga kungabonisa ukuthi ukukhulelwa kufanele kuthuthukiswe kakhulu.
Ngaphezu kwalokho, uma izilinganiso ze-ultrasound zibonisa isibalo se-fetal kanye / noma ukushaya kwenhliziyo kufanele kube khona futhi akusikho, udokotela angase ahlole ukuthi ukuphuma kwesisu kungakanani. I-American Mining Association iveza isiqondiso sokuthi uma isikhwama sokugaya singaphezu kwamamitha angu-16-18 futhi singenayo isibalo se-fetal noma uma isigxobo sesibusiso sikhulu kunamamitha ayi-5 futhi singenayo inhliziyo, ukukhulelwa kwesisu kwenzeka. (Lezi zimo zizobizwa ngokuthi i- ovum elikhanyisiwe noma ukushiywa kwesisu okulahlekile , ngokulandelana.)
I-Ultrasounds for Ukuqinisekisa Ukulahlekelwa Kwokukhulelwa Kwangemva kwesikhathi
Ukwaziswa kulokhu kuhamba ngokuqondile ku-ultrasounds okwenziwe ekuqaleni kokukhulelwa, ikakhulukazi ekuqaleni kwe-trimester yokuqala, ngaphambi kwamasonto ayisikhombisa okukhulelwa. Njengoba ukukhulelwa kuqhubeka, i-ultrasound iba nenembile ngokwengeziwe ekunqumeni ukufaneleka kokukhulelwa. Uma i-ultrasound ku-trimester yesibili noma yesithathu ibonisa ukuthi ingane ayinayo inhliziyo, lokhu kubhekwa njengokuqinela ukuxilongwa kokulahlekelwa kwesisu noma ukubeletha okuzayo.
