I-placenta yinyama enxibelelwano ngoncedo apho utshintshiselwano lwempahla eluncedo kunye nemveliso yomsebenzi obalulekileyo phakathi komama kunye nomntwana ozalisayo. Kumntwana okhulelweyo, uqhotyoshelwe ngentambo yomlomo. I-placenta inikezela nomzimba womntwana ngokukhuseleka kwe-immunological: idlula emzimbeni umntwana wesifo somama. Ngaphandle kwe-placenta, ukukhula nokuphuhliswa kwesisu esibelethweni kwakungenakwenzeka.
I-detache ye-placenta kwisifundo esiqhelekileyo sokukhulelwa kwenzeka emva kokuba umntwana ezalwe. Ngokwezibalo, i-detachment yangaphambili ye-placenta ivela kwiimeko ezimashumi asibhozo. Ukususela kumashumi amathathu ukuya kwamashumi amathathu kwimihlanu kwimizekelo yeemeko ezinjalo zenzeka ngexesha lokukhulelwa, amatyala asele e-placenta aqoshiwe ngexesha lobasebenzi, ngexesha lokuqala.
Iimbangela zentambo ye-placenta
I-detache ye-placenta kubasetyhini abakhulelweyo kaninzi kwenzeka ngexesha lokukhulelwa kokuqala. Kwiindawo eziqhelekileyo zeplacenta, izizathu zecandelo layo lihlukaniswe ngamaqela amabini:
- Iqela lokuqala lezizathu . Ukuze iqhube i-provocators echaphazela ukuphuhliswa kwesi sifo ngokuthe ngqo: i-nephropathy okanye i-toxicosis efikeleleka, eqhubekayo ixesha elide, kwaye ayiphilanga ngokupheleleyo. Eli qela liquka izifo zeentso, ukukhubazeka kwentliziyo, ukuphulwa komfutho wegazi, isifo sikashukela , ukuphazanyiswa kwe-correl, i-thyroid gland. Kwaye kunye nezifo zegazi, ukungalunganga kwesisu kunye nemisebenzi eyenziwe kuyo, i-systemic lupus erythematosus. Oku kuquka ukungahambelani kweR Rh kunye namaqela egazi omntwana kunye nomama kunye ne-perenashivanie.
- Iqela lesibini yezizathu . Iquka izinto ezibangela ukuphazamiseka kwamaplazi kwimeko yezixazululo ezikhoyo: umntwana omdala, isifo sengqondo esiswini, ukugqithiswa kweendonga ze-uterine ngenxa yokukhulelwa okubanzi okanye i-polyhydramnios. I-Polyhydramnios inokubangela ukukhutshwa ngokukhawuleza, okukhawulezayo kunye nokugqithiseleyo kwe-amniotic fluid, ekwasongela ukufaka i-placenta. Ukuchithwa koqhagamshelwano lwe-uterine yesivumelwano kunye nokusetyenziswa okungafundiwe kweziyobisi ze-uterotonic ngexesha lokubeleka kwiimeko ezininzi zibaxhaphaza ukuphuhliswa kwesi sifo.
Ezi zilapha ngasentla zibangelwa ukuba kutheni i-placenta idibanisa: ukuphazamisa uxhulumaniso phakathi kweendonga zesibindi kunye ne-placenta, kubangela ukugqitywa kweempahla kwaye kubangele i-hemorrhages (i-retrocolocular hematomas).
Iimpawu zokugqithiswa kwebala
Iimpawu zentsimbi ye-placental ngexesha lokukhulelwa lixhomekeke kwixesha lokukhulelwa kunye neqondo lokukhubazeka. Iqela le-placenta yesigaba sokuqala sobunzima kwiinqanaba zokuqala akuyona ingozi njengemihla kamva. Oku kubonakaliswa ngophala kwamanzi. Kwinqanaba lokuqala lobunzima umntwana akahluphekanga. Kule meko, ukuya kuma-30 ekhulwini kwipentecenta exfoliates. Ngonyango olufanelekileyo, ukukhulelwa kuyaqhubeka kungekho nkathazo.
Ukuba ukuphazamiseka kweplacental kwenzeka kwisiqingatha (isiqendu sesibini sokubandezeleka), ke kukho umngcipheko wokuba kwenzeke okokuyingozi ukufumanisa i-placenta-fetal hypoxia, edla ngokuba yimbangela yokufa kwakhe. I-Detachment ye-placenta ingabangela i-intrauterine-hemorrhage yowesifazane. Emva koko umsebenzi owona mkhulu usindiso lomama.
Ukuphazamiseka kwe-Placental kuhamba kunye neentlungu zesisu, umfutho wegazi ophezulu wesibindi, ukukhubazeka komzimba womntwana. Inqanaba lesithathu lokuxhatshazwa kwamaplaza lihamba kunye nokugqitywa okupheleleyo kwepencental kwi-uterus. Kule meko, eyona yingozi kakhulu iyabonwa, yintoni esongela i-detache ye-placenta kukufa komntwana.
Unyango lwendlela yokupasa
Unyango, kwindawo yokuqala, kuxhomekeke kubukhulu be-pathology kunye nexesha elaphuhlisiwe ngalo. Ngexesha elide ukuya kwiiveki ezingamashumi amabini, ukukhulelwa kuyazama ukugcinwa kwaye kugcinwe ngokufanelekileyo. Ngokukhulelwa kwexesha elipheleleyo, oogqirha bavuselela ukubeletha, kwaye ukuba i-detachment ayibalulekanga, umfazi unokuzala kuphela. Ngomkhosi omkhulu emva komhla wokugqibela, icandelo le-caesarean lenziwa.
Ukubonakaliswa kancinci kweempawu zekliniki kuyisilathisi sokubhedlelelwa kwindoda ekhulelwe. Ngelo xesha, i-system ye-coagulation inkqubo ijongwe kwaye ihlolwe ngokusebenzisa i-ultrasound kwi-dynamics.
