Uphando luqhutywa phi kwaye nini?
Ngokuqhelekileyo kwiimeko ezinje, i-ultrasound iyisigxina, i.e. inzwa ifakwa kwindonga yangasese yomzimba. Imfuneko yokuqala ibhanti egcweleyo. Ngoko ke, ngaphambi kokuba inkqubo iqale, ibhinqa, ngokuchanekileyo kwiiyure eziyi-1 ukuya ku-5 ngaphambi kwalo, kufuneka uphuze i-500-700 ml yamanzi. Ukuba isifundo senziwe kusasa, umfazi ucebise ukuba angagcina iiyure eziyi-3-4.
Ngokweziko, i-ultrasound ekuhlolweni kokuqala kwenziwa kwiiveki ezili-12 zokukhulelwa. Ngelo xesha, inqubo efanayo iyavunyelwa kwisithuba seveki ze-11-13 zesigxina.
Yintoni i-ultrasound ebonisa kwiiveki ezili-12 zokukhulelwa?
Ukufunda isantya sophuhliso kwenziwa ngokukodwa ngexesha leeparitha eziliqela. Izalathisi eziphambili ezithelekiswa nesiqhelo kwaye zihlala ziqwalaselwa kwi-ultrasound kwiveki ye-12 yokukhulelwa zi:
- I-KTP - ubungakanani beparietal. Umgama ukusuka kumda we-parietal bone kuya kwi-coccyx;
- I-BDP - ubungakanani biparietal - umgama phakathi kwama-tubari ama-2 e-parietal;
- I-TVP - ubukhulu bekhola indawo.
Ukucacisa iziphumo zokukhulelwa kwiiveki ezili-12 ze-ultrasound kwaye ukuthelekisa kwiimimiselo zenziwa ngogqirha zisebenzisa itafile.
Ngelo xesha, oogqirha banokusekwa:
- uphuhliso olulinganayo lwe-hemispheres ye-cerebral, ukuhlawula ngokukhethekileyo isakhiwo;
- ukuvavanya umsebenzi we-cardiovascular system, ngokulungisa isantya senhliziyo;
- ukuvavanya uphuhliso lomzimba olupheleleyo lomntwana ngokulinganisa ubude bexala, intamo, ishinyi, iphambili.
Ingqwalasela ekhethekileyo kweso shenyi isuswa ngokuhlolisisa i-placenta, ukulungisa ubungqina bayo kunye nesayithi yokuqhotyoshelweyo. Ukongezelela, ugqirha uyayihlola ngokucophelela intambo, kuba ngokuthe ngqo oko isiqhamo sithola izinto ezinobomi kunye ne-oxygen. Ukungafani phakathi kobukhulu beempahla kunye nesiqhelo kungabonisa ngokuthe ngqo ukuba kuphuhliso lwe-oksijini yindlala yecala, echaphazela kakubi ukuphuhliswa kwayo.
Ngaloo ndlela, njengoko kubonakala kwinqaku, i-ultrasound kwiveki ye-12 yokukhulelwa enye yezona zifundo zibalulekileyo zikwazi ukubona ukuphulwa kwixesha elifutshane kakhulu.
