Ukungasebenzi kahle kwamapayipi (ekuguleni komzimba, ukungakwazi ukusebenza kwesifo sengqondo) kuyinkimbinkimbi yonke yezibonakaliso ezizibonakalisa ngokwengxenye ye-placenta futhi, ngenxa yalokho, kusukela ekuthuthukiseni i-fetus.
Qhathanisa ukungakwazi kahle kwe-placental kanye nefomu layo elingapheliyo.
Ukuntuleka okunamandla kokutholwa kwe-fetoplacental kubonakala ngokukhubazeka okunamandla ekugezeni kwegazi phakathi kwe-placenta nomntwana. Ngenxa yokuthi ingane ayitholi oksijini okwanele, kanye nezakhi. Ukukhubazeka okunamandla kubonakala izimpawu ezifana nokuphazamiseka kwamapayipi futhi ngenxa yokuphuma kwezinga elihlukahlukene. Kulokhu, ukubelethwa okuphuthumayo kowesifazane okhulelwe kuyadingeka. Isimo somntwana esesibelethweni sincike kunoma yiliphi ingxenye ye-placenta inqola yamathisisi okwenzekile.
Ifomu elingapheli kunzima kakhulu ukuxilonga, ukuthuthukiswa kwalo kuyashesha futhi kungenzeka kungahambisani nezimpawu.
Njengoba kungasebenzi kahle kwe-placenta, ukuhlaziywa okubaluleke kakhulu ukutadisha kweDoppler ekugezeni kwegazi okwakhulelwe. Lona uhlobo lwe-ultrasound, lapho igazi eligeleza khona ukusuka e-placenta kuya emfubeni lihlolwe, kanye nesisu. Lolu cwaningo luqhutshwa ku-dynamics ukuveza isithombe esinembile.
Okunye okungavamile kwe-placenta
I-cyst ye-placenta ingaholela ekungeneni kahle kwe-placental. I-cyst isakhiwe endaweni yokuvuvukala, uma kwakhiwa ngaphambi kweviki lama-20 lokukhulelwa - lokhu kuthathwa njengokujwayelekile, kodwa ukubunjwa kamuva kwe-placenta cyst kubonisa ukuvuvuka kwamuva. Kulesi simo, udokotela ukhetha ukwelashwa, futhi njengoba umthetho, ukwelashwa kuqukethe inkambo ebuyisela ukugeleza kwegazi ku-placenta.
Ukuvuvukala kwe-placenta
Lesi sifo esiphundu sitholwa yi-ultrasound. Ukuvuvukala kwe-placenta ukuqina kwe-placenta ngokwayo, kwenzeka uma umama enesifo se-intrauterine, futhi kungenzeka nakwiziguli ezine-diabetes mellitus futhi esimweni senkinga yokuphikisana ne-rhesus kumama one-fetus. Njengazo zonke izimo ezihlukumezayo nokungajwayelekile ezingeni le-placenta, ligcwele iqiniso lokuthi i-placenta ngeke ikwazi ukubhekana nemisebenzi yayo kahle, futhi ingane ingadli kahle nge-oxygen nezakhi.
Ukuphuma kwe-placenta
Ukuphuka kwe-placenta kuyinto engavamile. Kungenzeka ngemva kwamasonto angama-20 okukhulelwa, lapho i-placenta isakhiwe ngokugcwele. Izimpawu ezihlala zikhona lapho i-placenta iphukile kuyisifo esibuhlungu esiswini esingaphansi, kanye nokuphuma kwegciwane lesisu. Ingozi yokuphuluka kwe-placenta ibhekwa kwabesifazane abahlukunyezwa yisifo sikashukela.
Infarction ye-placenta
Infarction ye-placenta yilapho ibonakala khona i-placenta ngenxa yokuphazamiseka kwegazi. Uma ukuhlaselwa kwenhliziyo kuthinta ingxenye encane kakhulu ye-placenta, cishe cishe ngeke kuphazamise ingane nganoma iyiphi indlela, kepha uma isayithi enevolumu okungenani amasentimitha amathathu sithintekile, lesi simo singabangela ukungakwazi ukusebenza kwe-fetoplacental.
Zonke lezizinto ezingavamile ze-placenta ezivela embusweni wayo ojwayelekile ziholela ekuthuthukisweni kokukhubazeka nokubambezeleka kwe-fetus. Uma ukungasebenzi kwe-placenta kudinga ukunakekelwa kwezokwelapha njalo, kanye nokwelashwa okufika ngesikhathi.
Ukwelashwa kuthatha isikhathi eside kakhulu, futhi kuqhutshwa esibhedlela. Ukuqapha owesifazane okhulelwe nganoma yikuphi kwalokhu kutholakala kwenzeka kuze kube sekulethwa kwezidingo, ngenxa yobungozi obukhulu bokufiphala kwe-fetal, ukuphuka kwe-placenta nezinye izinkinga eziningi.
Ukuvimbela
Ukuvimbela ukungakwazi ukusebenza kwamathambo kubalulekile kakhulu. Ukuze wenze lokhu, kubalulekile ukubhalisa ngesikhathi, ukudlula zonke izivivinyo, ngoba ukutholakala kwenkinga ngesikhathi esifanele kuzogwema imiphumela emibi. Futhi, owesifazane okhulelwe kudingeka ahambe ngangokunokwenzeka ngaphandle, aphumule emini futhi adle kahle.
