I-TWP ilinganiswe nini futhi kanjani?
Lesi sifundo senziwa ngesikhathi samasonto angu-11-13. Lokhu kuchazwa ukuthi emva kwamasonto angu-14 uketshezi oludlulayo olutholakalayo luxhunywe ngokuqondile yi-system lymphatic ekhulayo esibelethweni sesisu somntwana.
Ngemva kokulinganisa usayizi we- coccygeal-parietal, udokotela usebenzisa i-transducer ye-ultrasound ukuthola amanani we-TVP wesisu, okuhluka phakathi kwamasonto okukhulelwa, futhi uqhathanisa amanani atholakala netafula. Ngesikhathi esifanayo, uketshezi oluncibilikisiwe luhlelwe ngendlela yebhande elimnyama ekuqapheni kwedivayisi, futhi isikhumba - esimhlophe.
Imiphumela yesilinganiso ilinganiswa kanjani?
Yonke imigomo ye-TVP ihlelwe amasonto, futhi iboniswa kuthebula elikhethekile. Ngakho, ngokwesibonelo, emavikini angu-11, ukuqina kwalesi sikhala sekhalenda akumele kudlulele u-1-2 mm, futhi ngesikhathi samasonto angu-13 - 2.8 mm. Kulesi simo, ukwanda kwenani laleli parameter kwenzeka ngokuqondile ngokukhula komntwana.
Ukwanda kwalesi sibonakaliso akusho ngaso sonke isikhathi ukutholakala kwempilo. Ngakho-ke, ngokwezibalo, izingane ezingu-9 kwabangu-10, abakwa-TVP abangama-2.5-3.5 mm, bazalwa ngaphandle kwezinkinga zempilo. Ngakho-ke, ukuhlolwa kwemiphumela kufanele kwenziwe kuphela udokotela othi, ngaphezu kokuqhathanisa amanani nalabo abathintekayo, ucabangela izici zomuntu ngamunye wesikhathi esizayo. Ngaphandle kwalokho umama ozayo uzozama ukuthola imiphumela ngokuzimela.
Kodwa-ke, ephakeme inkomba yalesi ipharamitha, kungenzeka ukuthi ingane izoba nokungafani kwe-chromosomal. Isibonelo, nge-TVP elingana no-6 mm, kungashiwo ngokuqiniseka ukuthi umntwana ozelwe njengomphumela wokukhulelwa okunjalo uzoba nokuphulwa kumadivayisi we-chromosomal. Futhi lokhu akuyona nje i-Down syndrome.
Ngakho-ke, i-TWP, eguquguqukayo ngamasonto okukhulelwa futhi ehlaziywa ngetafula, ibhekisela kulawo mbonakaliso evumela ukutholakala kokuqala kwezinkinga zokuthuthukiswa kwentombazane ye-intrauterine.
