I-placenta yiyona nxalenye ebaluleke kakhulu ngexesha lokukhulelwa, apho kuxhomekeke khona-kangakanani ubuninzi bomntwana oza kunikwa i-oxygen kunye nezondlo. Zininzi izinto ezichaphazela ukuchaneka kwe-placenta ukwakheka: izifo zentsholongwane ezihanjiswe ngexesha lokukhulelwa, ubukho bentsholongwane ngokwesondo, i-Rh-conflict, imikhwa emibi kunye nabanye. Ukukhula kwepentecenta ngokuqhelekileyo kuyaqhubeka kude kube iiveki ezingama-37, ekupheleni kokukhulelwa kungancipha. Imeko ye-placenta imiselwe kuphela nge-ultrasound.
Indlela yokujonga ubungakanani bepentecenta?
Ubungakanani be-placenta bubalwa yi-ultrasound kwindawo ephakamileyo. Ngokomlinganiselo we-placenta, umntu unokuvavanya imeko yayo kunye nokwanela kwemisebenzi yayo. Ngoko, ukwanda kwamaplacenta kunokuthetha nge-placenta, intsholongwane, ingxabano ye-rhesus, isifo sikashukela okanye i-anemia. Umfazi onjalo kufuneka abhaliswe ngokuthe ngqo kwi-gynecologist yezilwanyana kwaye ahlolwe ngenxa yeentsholongwane kunye nezifo. I-Hypoplasia ye-placenta okanye ukunqumla kwayo, inokuthetha ngokunxulumene nobukho bempilo kumfazi okhulelwe (amathuba okungaqhelekanga ngokwemizimba ephezulu). Kwiimeko zombini, i-placenta ayikwazi ukwenza ngokufanelekileyo imisebenzi yokuhambisa i-oksijini kunye nezondlo.
Iimpawu eziqhelekileyo zobungakanani be-placental kwiiveki
Makhe siqwalasele ngeliphi ixesha lokukhulelwa ukuba bunjani ubungakanani be-placenta kunokubhekwa njengesiqhelo.
Kwixesha le- fetal kwiiveki ezingama-20, ubukhulu be-placenta ngokuqhelekileyo ngu-20 mm. Kwimizuzu engama-21 neye-22-ubukhulu obuqhelekileyo be-placenta buhambelana no-21 no-21 mm, ngokulandelanayo. Ubunzima be-placenta 28 mm buhambelana neveki yama-27 yokukhulelwa.
Ubungakanani be-placenta kwi-31, 32 neye-33 yeeveki zesigxina kufuneka zihambelane ne-31, 32 ne-33 mm. Ukuphambukiswa okuncane kumanqaku aqhelekileyo akusona isizathu sokukhathazeka. Ukuba iimpazamo ezivela kwimimiselo ziphawulekayo, ngokuphindaphindiweyo ukuxilongwa kwe-ultrasound, i-dopplerography kunye ne-cardiotocography ziyimfuneko. Ukuba imeko yomntwana iyanelisayo, ngoko ke unyango aluyimfuneko.
Isikhathi ngasinye sokukhulelwa sihambelana nemida ethile yemimiselo ngokwemigangatho ye-placenta. Kwaye ugqirha obona umfazi okhulelweyo, ebone utshintsho kwi-placenta ehambelana neziphumo ze-ultrasound, ngokuqinisekileyo uya kubabela iindlela ezongeziweyo zokuphanda ukuqinisekisa iindlela zokunyanga.
