Abaphandi baye bajonga imilinganiselo ekulindelwe ngamaphuzu athile ekukhulelweni kokuqala, ngoko ukukhangela kwe-ultrasound yokuqala kunokunika udokotela ulwazi olubalulekileyo.
Ukusetyenziswa okuqhelekileyo kwe-ultrasound ekukhulelweni kokuqala kukubala iminyaka yobudala . Ngenxa yale njongo, i-ultrasound ithathwa njengendlela echanekileyo yokuthandana nokukhulelwa. Ekukhulelweni okuqhelekileyo, iziphumo ze-ultrasound zinganikezela ukuqikelelwa kwexesha lokunyamekela ukuya kwiintsuku ezintlanu ukuya kwezixhenxe zokuchaneka.
Xa umfazi ephethe iimpawu zokukhulelwa komzimba , ugqirha unokuyalela enye okanye ngaphezulu i-ultrasounds ukucacisa ukufaneleka kokukhulelwa.
Indlela yokukhulelwa kwangaphambili kwe-Ultrasound Works
Kwi-trimester yokuqala, oogqirha bavame ukusebenzisa i-ultrasound yangasese kunokuba babuthe ulwazi malunga nokukhulelwa. I-ultrasound ye-transvaginal inikezela ngolwazi oluchanekileyo ekukhulelweni kokuqala, ngenxa yokuba isiqalo sokuqala sokukhulelwa kunye nesimbolo somntwana esifubeni sincinci kakhulu kweli nqanaba kwaye i-ultrasound yangasese ingasondeza ekukhulelweni kokukhulelwa.
Kwi-ultrasound engapheliyo, ugqirha okanye ugqirha ufaka umtshini obuncinci kumfazi ukuze uthathe uluhlu lwesilinganiselo, kuquka ubukhulu besigxobo somzimba, ubukhulu be-yolk sac, ubude bomthi we-fetal, nentliziyo izinga.
Kwi-ultrasound esiswini, lo mfazi uya kucelwa ukuba eze kwi-scan kunye nesibindi esipheleleyo, kuba ezi zikhundla i-uterus ngendlela eyenza kube lula ukufumana imilinganiselo. Ugqirha okanye ochwepheshe usasaza i-gel phezu kwesisu esezantsi kwaye usebenzisa i-transceiver ukuba athathe amanani ukusuka kwinani leengalo.
Iziphumo ezilindelekileyo ze-ultrasound ngeveki yokukhulelwa kwangaphambili
Lawa maxabiso xa amaxesha athile ophuhliso lokukhulelwa kwangaphambili afunyanwa yi-ultrasound yangaphakathi. Ngokuqhelekileyo, i-ultrasound yesisu ayinakucinezeleka kwaye ayinakuzibona ezi zinto zihambile kude kube ngeveki okanye emva kokukhulelwa.
Khumbula kwakhona ukuba naluphi na ukungaqiniseki malunga nomhla wokuvuthwa kunokuchaphazela oko i-ultrasound iya kubonisa nanini na ukukhulelwa kwangaphambili.
Kutheni Iziphumo eziPhambili zeZiphumo eziKhuselekileyo zingabonakali ekunqumeni ukutshatyalaliswa komtshato
Iziphumo ze-ultrasound zifaniswa nento ekulindeleke kwixesha lokukhulelwa. Ubudala beminyaka yobudala kubalwa kwinani leiveki ukususela kwixesha lokugqibela lokuya esikhathini; nangona kunjalo, le ndlela iqukumbela umjikelezo weentsuku ezingama-28 kunye ne-ovulation eyenzeka ngomhla we-14. Abasetyhini abaninzi banemizuzu emifutshane okanye emide kwaye abavuthanga ngomhla we-14-kwaye oku kunokuchaphazela ukuba i-ultrasound ibonise ntoni ekuphuhlisweni kokukhulelwa.
Ngokomzekelo, ukuba ibhinqa linomjikelezo wesigxina seentsuku ezingama-35, i-ovulates ihamba ngeenxa zonke ngosuku lo-21 lomjikelezo wakhe wokuya esikhathini (kuba i-ovulation idla iiveki ezimbini ngaphambi kokuba kufike ixesha lokuya esikhathini). Ukuba le ntokazi yayikhulelwe kwaye i-ultrasound ihlola iiiveki ezintandathu ukusuka ekupheleni kwakhe kwexesha lokuya esikhathini, ngokuqhelekileyo ukukhulisa ukukhulelwa kuya kulinganisa neminyaka yobudala bexesha elidlulileyo. wenza. Ukuba loo ntokazi ayengazi ukuba i-ovulated ngosuku lwesi-21 lomjikelezo wayo, unokukhathazeka ngokungabalulekanga ukuba wayenomkhuhlane okhulelweyo xa wayenomdla wokuqala ukukhulelwa xa ekhulile "esebenzisa iiveki ezintandathu ukhulelwe. "
Ngokufanayo, akuyena wonke umntu ohamba ngokukhawuleza ukuqala kwexesha lokuya esikhathini. Ukuba umfazi akakwazi ukukhumbula xa ixesha lakhe lokuya esikhathini liqala kwaye uqikelele umhla olungafanelekanga, nokuba ngaba unomjikelezo wemihla ngemihla engama-28, oku kungatshintsha neziphumo ezilindelekileyo zokutshintshwa kwe-ultrasound.
Ekukhulelweni kokuqala, isikhwama somzimba kunye nesibindi sitshintshisa kakhulu imihla yonke, ngoko ukuphuma kunye neentsuku ezimbalwa kunye nobudlelwane kungenza umehluko nokuba ingaba i-ultrasound ibone i-heartbeat.
Isikhumba se-Gestational Sac / Ayikho I-Fetal Heartbeat / Ayikho i-Fetal Pole
Ngamanye amaxesha i-ultrasound iya kunika iziphumo ezingaqinisekanga. Umzekelo, ukuba ibhinqa iiveki ezisixhenxe zikhulelwe kwaye i-ultrasound ayibonakalisi intliziyo yesisu, ugqirha unokuyalela enye i-ultrasound ngeveki. Ukukhulelwa kusenokuqhelekileyo kodwa kuphelelwe yintsuku embalwa ekuthandeni-okanye ukutshata kungachaneka kodwa ixesha lisekhona kumgama wephutha xa i-heartbeat ibonakala kwi-ultrasound.
Ngokufanayo, ukuba i-ultrasound ibonakalisa isikhwama esingenanto esingenanto, le nto ingaba yinto eqhelekileyo yokufumana ukuba ukukhulelwa kusondele. Umntwana okhulayo uncinci kakhulu ukuba angabonwa kwi-ultrasound kude kube neveki ezintlanu zesini. Kule meko, ugqirha unokukhetha ukuphinda i-ultrasound ngosuku oluthile.
Kukho nawa maxesha, iziphumo ze-ultrasound zingabonisa ukuphuphuma kwesisu okanye ukukhulelwa kusenokuqhelekileyo. Ukuba i-ultrasound elandelayo ibonisa ukuba ukukhulelwa kuye kwaqhubeka kuphuhliswa, iziphumo zangaphambili zibangelwa kwiingxaki zokuthandana. Ukuba i-ultrasound esilandelayo isabonakalisa uphuhliso olungavumelekanga, ugqirha unokukwazi ukuxilonga ngokungahambi kakuhle-kodwa ugqirha akakwazi ukucacisa umphumo esekelwe kuphela kwi-pregnancy eyodwa ukukhulelwa kwe-ultrasound kwiimeko ezininzi.
Ukulinda i-ultrasound ephindaphindiweyo kunokuba nzima kakhulu ngokomzwelo, kodwa kunokuba kuyimfuneko ukwenzela ukuba ugweme ukungahambi kakuhle ngaphandle kokuba enye ingcaciso ikhona ukunceda ugqirha ahumushe iziphumo ze-ultrasound.
Indlela yeHCG okanye ezinye iinkcukacha ezinokunceda ukuchazwa kwe-Ultrasound
Ukuba kukho nayiphi na umbuzo malunga nokuba ingaba umfazi unesifo sokuphuphuma kwesisu esekelwe kwiskripthi se-ultrasound, inkqubo yesenzo esiqhelekileyo kukuba ugqirha uya kulawula enye i-ultrasound ezinsukwini ezimbalwa okanye ngeveki.
Ngamanye amaxesha, nangona kunjalo, ubukho bezinye iinkcukacha zokuxilonga lunokunceda ugqirha ukuba aguqule iziphumo ze-ultrasound nangona kukho enye i-ultrasound scan. Umzekelo, ukuba ibhinqa linokuhlolwa kokukhulelwa okulungileyo ngosuku lwexesha elaphosiweyo lilandelwa ukuqinisekiswa ngeempembelelo ze-hCG zegazi kunye ne-ultrasound emva kweeveki ezine kamva kubonisa ukukhulelwa kwiiveki ezintlanu kuphela, ubugqirha unokugqiba ukuba le ntokazi sele ukukhulelwa kwesisu-ngenxa yokuba ukukhulelwa okulungileyo kwinyanga enye ngaphambili bekuya kubonisa ukuba ukukhulelwa kufuneka kuphuhliswe ngakumbi.
Ukongezelela, ukuba imilinganiselo ye-ultrasound ibonisa umzobo wesisu kunye / okanye intliziyo kufuneka ibe khona kwaye akusiyo, ugqirha unokufumanisa ukuphuphuma kwesisu. Umbutho waseMelika wokukhulelwa ubeka isikhokelo ukuba ukuba isikhwama sokugaya sinamandla kunama-16-18 milimitha kwaye asiqukethe umzobo wesisu okanye ukuba isibonda se-fetal sikhulu kuneemitha eziyi-5 kwaye asinayo intliziyo, ukukhulelwa komzimba kuye kwenzeka. (Ezi meko ziza kuthiwa yi- ovum ephazamisekileyo okanye ukulahlekelwa ngokungahambi kakuhle , ngokulandelanayo.)
I-Ultrasound for Confirming Late Pregnancy Loss
Ingcaciso kule ndlela ihamba ngokuthe ngqo kwi-ultrasounds eyenziwe ekukhulelweni kokuqala, ngokukodwa ekuqaleni kwe-trimester yokuqala, phambi kweeveki ezisixhenxe zokukhulelwa. Njengoko ukukhulelwa kuqhubeka, i-ultrasound iba nechanekileyo ngakumbi kwaye ichaneke ngakumbi ekunqumeni ukufaneleka kokukhulelwa. Ukuba i-ultrasound kwisiqingatha sesibini okanye yesithathu ibonisa ukuba umntwana akanalo intliziyo, oku kuthethwa ngokugqithiseleyo ukuxilonga ukulahleka kwegazi okanye ukusalela .
