Umbuzo wokuba unobungozi ukwenza i-ultrasound ngexesha lokukhulelwa, aluniki ukuphumla kubo bonke oomama bokamva. Nangona kunjalo, ngelishwa akunakwenzeka ukufumana impendulo engabonakaliyo kulo mbuzo. Abanye oogqirha bakholelwa ukuba izixhobo zanamhlanje azibangeli nantlungu na kumama nomntwana, kodwa kukho abo bathi ukuba ukuphazamiseka okunjalo akunakudlulela ngokupheleleyo ngaphandle kokulandelelana, kwaye bathi enye inzakalo iyenzeka.
Kodwa ukuba ucacisa kwesi sihloko uze uqhathanise nezimvo zeengcali, ngoko siza kwisigqibo sokuba i-ultrasound kufuneka yenziwe. Ekubeni inokulimala ekusebenziseni kwayo kusekho ngaphantsi kweengxaki ezingabonakaliyo. Nazi izibonelo: ngexesha le-ultrasound, kunokwenzeka ukufumanisa iziphene zentuthuko yomntwana (i-Down's syndrome, isifo senhliziyo, njl njl), izifo zangaphakathi, imeko kunye nesimo samanzi e-amniotic, imeko kunye nesimo se-placenta, iqondo lokuguga, ubukho okanye ukungabikho kokugxininisa nokunye okuninzi . Ngokukodwa xa ucinga ukuba uninzi lwezinto ezimbi zingathinteka, ukulimala kwinkqubo yokuxilongwa kwe-ultrasound kubonakala kuncinci. Nangona kunjalo, umntu kufuneka akhumbule umgaqo wegolide ukuba yonke into ifanele ibe ngokumodareyitha. Ukwenza i-ultrasound imihla ngemihla ukuze uqinisekise ukuba umntwana ulungile, okanye ukumbona nje, okanye uzama ukuqonda ubulili bomntwana-akukhona nje kuphela, kodwa kunobungozi. Ngako oko umbuzo uvela ngokwemvelo, kodwa zingaphi kangangoko unokwenza i-ultrasound ukhulelwe?
Malunga nokuba kaninzi kangakanani unokwenza i-ultrasound, akukho mvumelwano phakathi koogqirha. Kodwa ininzi yabo ikholelwa ukuba ikhefu elincinci phakathi kwe-ultrasound diagnostic of the fetus kufanele libe liveki ezimbini. Nangona kunjalo, konke kuxhomekeke kwimeko nganye. Kwaye malunga nokuba kunokwenzeka ukuba umfazi othile okhulelweyo enze kaninzi i-ultrasound okanye ayikho, unokumxelela kuphela umfazi wezintlu. Akuqhelekanga ukuba i-placenta igugile, kwaye imeko yayo kunye nomgangatho wemisebenzi yayo kufuneka ihlolwe rhoqo. Kule meko, i-ultrasound ingenziwa kanye ngeveki, kwaye emva kweveki ezingama-40 kwanamaxesha angama-2-3 ngeveki. Kodwa kunye nokulungiswa okukuphela kwesi sihlandlo asiyi kuphinda sihlolisise kwaye silinganise iipameter ze-fetus, kwaye siya kujonga kuphela kwi-placenta, kwaye ayisayi kuthatha ngaphezu kwemizuzu emi-5.
Zingaphi kangangexesha ukukhishwa kwe-ultrasound kukhulelwe?
Xa ukhulelwe, uphando olunzulu olufunekayo lwe-ultrasonic lwenziwa.
Ukuhlolwa kokuqala kwenziwa kwithuba leeveki ezili-11 ukuya kwe-14. Ngethuba elifanayo, inani lamabele, iintliziyo zihlolwe, zonke iinxalenye zomzimba womntwana zilinganiswa, kwaye ubukho babo buhlolwe. Ukongezelela, i-ultrasound yokuqala ilungiswe ukudala ubudala, kwaye ubukho okanye ukungabikho kwesongelo sokupheliswa kokukhulelwa kuhlolwa.
Ukuhlolwa kwesibini kwenziwa kwithuba leeveki ezingama-20-24. Oku kuhlolwa kubaluleke kakhulu, kwaye ukuhamba kwayo ibhinqa elikhulelwe lidla ngokubhekiselele kwii-geneticists. Ukususela ngeli thuba le-ultrasound zonke izitho zangaphakathi zomntwana zilinganiswa (inani lamagumbi entliziyweni kunye nomsebenzi walo, imilinganiselo yengingqi yengqondo, isimo sezintso kunye ne-adrenals, nokunye okuninzi). Kwisigaba esifanayo, kunokwenzeka ukuchonga izifo ezikhoyo zofuzo (i-Down syndrome efanayo),
Kodwa kukho okubizwa ngokuba yi- third screening . Akayinyanzelo, kwaye umiselwa kuphela ngugqirha. Ubanjwe kwiiveki ezingama-32 ukuya kuma-36. Esi sikrini sivavanya urhulumente we-placenta, isixa kunye nemeko ye-amniotic fluid, imeko yombambo we-umbilical, ithatha ubunzima bomntwana, kwaye iphinda ihlole intsingiselo (intloko, i-gluteal, njl.
