Abasetyhini abaninzi emva kwe-ultrasound bayatshitshisa isigqibo sokuba oogqirha bathi intambo yomtya inemikhumbi e-2 endaweni yezinto ezintathu, njengoko kulindeleke. Oogqirha abasoloko banika ulwazi olunzulu, kwaye abanomama baya kukhathazeka kakhulu malunga nemibuzo - yintoni enokuyenza kumntwana kwaye yintoni enokuyenza ukuze ugweme imiphumo. Iinqanawa ezi-2 kwintambo yesigxina - le yinto engavamile, okubangelwa yinto engafanelekanga yintsholongwane, rhoqo intliziyo ihlupheka.
Zingaphi iinqanawa kufuneka zibe nentambo?
Intambo yomlomo (intambo ye-umbilical) iyilungu elidibanisa umntwana kunye nomzimba womama, lifikelela kubude be-50-70 cm okanye ngaphezulu. Intambo yesibindi kufuneka ibe nemitya emithathu, oku: imibhobho emibini kunye nemvini enye. Nge-aplasia (uphuhliso olungalunganga) lomnye umthamo wentambo ye-umbilical, okungaqhelekanga kuvela - intambo ye-umbilical 2 yesitya, i-e. omnye umzobo kunye nomvini omnye. Umthamo uthwala igazi le-fetal, egcwele i-carbon dioxide kunye nemveliso yezinto ezinobungozi be-metabolism kwi-placenta yomama. I-veillical vein ithwala igazi, eliye lenziwe nge-oksijeni kunye nezondlo, ukusuka kwi-placenta kamama ukuya kwintsana. Ekuzalweni, iinqanawa ezi-2 kwintambo yesibindi zingabangela i-hypoxia ye-fetal, ngoko ke isigaba se-caesarean siboniswe kwiimeko ezinjalo. Ngethuba lokubeletha, umntwana kufuneka anikwe ingqwalasela ephezulu, njengoko ukuhamba kwegazi kunokukhubazeka xa usika intambo.
Ngethuba lokukhulelwa kubalulekile ukubonakalisa i-genetics ukuba ingabandakanyi i-chromosomal engafanelekanga (ugqirha ngokuqhelekileyo ubonisa ukwenza ikhadi-codeni-uvavanyo lwegazi olususwe kwintambo yomlomo). Kwakhona ukuya kwiiveki ezingama-24, kufuneka wenze i-ultrasound ye-heart fetal (ukukhusela isifo senhliziyo) kunye ne-ultrasound eyandisiweyo yezinye iziko. Ukuze kuphephe ukuphulwa, oogqirha baqesha i-CTG kunye ne-doppler yeveki nganye.
Ukuziqhelanisa kubonisa ukuba inani leenqwelo zomkhonto ezingabonakaliyo luthinta kakhulu impilo yomntwana. Kwaye ukuzalwa komntwana kunye nokuphambuka kweli phepha kunokwenzeka ukuba yinto engafaniyo: kwimpilo engakumbi yomntwana, omnye umzobo awunandaba.
