• Ziyini izingozi ze-cordocentesis

I-Cordocentesis, noma isampula yegazi lombungu, ukuhlolwa kokubeletha ngaphambi kokubeletha, okwenziwa ngemuva kwamasonto angama-18 noma angama-20 ekhulelwe, futhi kuqukethe ukuthatha isampula yegazi lengane entanjeni yesibeletho, ukuthola noma ikuphi ukushoda kwe-chromosomal enganeni, njenge-Down's I-Syndrome, noma izifo ezifana ne-toxoplasmosis, rubella, i-fetal anemia noma i-cytomegalovirus, isibonelo.

Umehluko omkhulu phakathi kwe-cordocentesis ne-amniocentesis, okuyi-2 test diagnostic diagnostic, ukuthi uCordocentesis uhlaziya igazi lenkaba yengane, kuyilapho i-Amniocentesis ihlaziya kuphela i-amniotic fluid. Umphumela we-karyotype uphuma ezinsukwini ezi-2 noma ezi-3, okungenye yezinzuzo kune-amniocentesis, ethatha cishe izinsuku eziyi-15.

Uyenza nini i-cordocentesis

Izinkomba zeCordocentesis zifaka ukuxilongwa kwe-Down syndrome, lapho ingatholakali nge-amniocentesis, lapho imiphumela ye-ultrasound ingacacisiseki.

I-Cordocentesis ivumela ukutadisha i-DNA, i-karyotype nezifo ezifana ne:

• Ukuphazamiseka kwegazi: I-Thalassemia ne-sickle cell anemia;
• Ukuphazamiseka kwegazi: I-Hemophilia, i-Von Willebrand's Disease, i-Autoimmune Thrombocytopenia, i-Thrombocytopenic Purpura;
• Izifo ze-Metabolic ezifana neDuchenne Muscular Dystrophy noma iTay-Sachs Disease;
• Ukuthola ukuthi kungani ingane ikhubazekile, futhi
• Ukukhomba ama-hydrops embungu, isibonelo.

Ngaphezu kwalokho, futhi kuyasiza kakhulu ekuxilongweni ukuthi ingane inesifo esithile esizalwe naso futhi kungakhonjiswa njengendlela yokwelashwa kokumpontshelwa igazi ngaphakathi kwesibeletho noma lapho kudingeka ukwelashwa ngemithi ekwelapheni izifo zombungu, ngokwesibonelo.

Funda ezinye izivivinyo zokuxilongwa kwe-Down Syndrome.

Kwenziwa kanjani i-cordocentesis

Akukho ukulungiselela okudingekayo ngaphambi kokuhlolwa, kepha owesifazane kumele ngabe wenza ukuhlolwa kwe-ultrasound nokuhlolwa kwegazi ngaphambi kwe-cordocentesis ukukhombisa uhlobo lwegazi lakhe ne-HR factor. Lokhu kuhlolwa kungenziwa emtholampilo noma esibhedlela, ngokulandelayo:

1. Owesifazane okhulelwe ulele ngomhlane;
2. Udokotela usebenzisa i-anesthesia yendawo;
3. Ngosizo lwe-ultrasound, udokotela ufaka inaliti ikakhulukazi endaweni lapho kuhlangana khona inkaba kanye ne-placenta;
4. Udokotela uthatha isampula elincane legazi lengane elino-2 kuya ku-5 ml;
5. Isampuli iyiswa elabhorethri iyohlolwa.

Ngesikhathi sokuhlolwa, owesifazane okhulelwe angathola amajaqamba esiswini ngakho-ke kufanele aphumule amahora angama-24 kuye kwangama-48 ngemuva kokuhlolwa futhi angaxhumani kakhulu izinsuku eziyi-7 ngemuva kwe-cordocentesis.

Izimpawu ezinjengokulahleka koketshezi, ukopha esithweni sangasese sowesifazane, ukucindezela, imfiva nobuhlungu esiswini kungavela ngemuva kokuhlolwa. Ukuqeda ubuhlungu nokungaphatheki kahle kungasiza ukuthatha ithebhulethi yeBuscopan, ngaphansi kweseluleko sezokwelapha.

Ziyini izingozi ze-cordocentesis

ICordocentesis inqubo ephephile, kepha inezingozi, njenganoma ikuphi okunye ukuhlolwa okuhlaselayo, ngakho-ke udokotela uyayicela kuphela lapho kunezinzuzo eziningi kunezingozi kumama noma enganeni. Izingozi ze-cordocentesis ziphansi futhi ziyalawuleka, kepha zifaka:

• Cishe 1 ingozi yokukhulelwa kwesisu;
• Ukwehla kwegazi endaweni lapho kufakwe khona inaliti;
• Kwehle ukushaya kwenhliziyo yengane;
• Ukuqhekeka ngaphambi kwesikhathi kwezingqamu, okungavumela ukulethwa ngaphambi kwesikhathi.

Ngokuvamile, udokotela uyala i-cordocentesis lapho kusolwa ukuthi kutholakala isifo sofuzo noma isifo esingatholakalanga nge-amniocentesis noma i-ultrasound.
