Yintoni iCordocentesis?

Umxholo

• Uyenza nini i-cordocentesis
• I-cordocentesis yenziwa njani
• Yeyiphi imingcipheko ye-cordocentesis

I-Cordocentesis, okanye isampulu yegazi olungekazalwa, luvavanyo lokubeleka ngaphambi kokubeleka, olwenziwa emva kweeveki ezili-18 okanye ezingama-20 zokukhulelwa, kwaye kubandakanya ukuthatha isampulu yegazi lomntwana kwintambo, ukuze kufunyanwe nakuphi na ukusilela kwe-chromosomal emntwaneni, njengeDown's Isifo, okanye izifo ezifana ne-toxoplasmosis, rubella, i-fetal anemia okanye i-cytomegalovirus, umzekelo.

Umahluko ophambili phakathi kwe-cordocentesis kunye ne-amniocentesis, ezi-2 zovavanyo lokuqonda kokubeleka, kukuba i-Cordocentesis ihlalutya igazi le-umbilical cord, ngelixa i-Amniocentesis ihlalutya kuphela i-amniotic fluid. Iziphumo zekaryotype ziphuma ngeentsuku ezi-2 okanye ezi-3, enye yeenzuzo ngaphezulu kwe-amniocenteis, ethatha malunga neentsuku ezili-15.

Uyenza nini i-cordocentesis

Iimpawu zeCordocentesis zibandakanya ukuxilongwa kwe-Down syndrome, xa ingenakufunyanwa nge-amniocentesis, xa iziphumo ze-ultrasound zingenakuphikiswa.

I-Cordocentesis ivumela uphononongo lwe-DNA, karyotype kunye nezifo ezinje:

• Ukuphazamiseka kwegazi: I-Thalassemia kunye ne-sickle cell anemia;
• Ukuphazamiseka kwegazi: IHemophilia, isifo sikaVon Willebrand, iTrombocytopenia ezenzekelayo, iTrombocytopenic Purpura;
• Izifo zeMetabolic ezifana neDuchenne Muscular Dystrophy okanye isifo seTay-Sachs;
• Ukuchonga ukuba kutheni usana lumi ngxi, kwaye
• Ukuchonga ii-hydrops zomntwana, umzekelo.

Ukongeza, kuluncedo kakhulu ekuchongeni ukuba umntwana unesifo esithile kwaye angaboniswa njengendlela yokonyango kutofelo-gazi lwangaphakathi okanye xa kufuneka kusetyenziswe iziyobisi kunyango lwezifo ezingekazalwa, umzekelo.

Funda ezinye iimvavanyo zokufumanisa isifo seDown Syndrome.

I-cordocentesis yenziwa njani

Akukho lungiselelo luyimfuneko phambi koviwo, nangona kunjalo umfazi kufuneka ukuba enze uvavanyo lwe-ultrasound kunye novavanyo lwegazi ngaphambi kwe-cordocentesis ukubonisa uhlobo lwegazi kunye ne-HR factor. Olu vavanyo lunokwenziwa kwiklinikhi okanye esibhedlele, ngolu hlobo lulandelayo:

1. Umfazi okhulelweyo ulele ngomqolo;
2. Ugqirha usebenzisa i-anesthesia yendawo;
3. Ngoncedo lwe-ultrasound, ugqirha ufaka inaliti ngakumbi ngakumbi kwindawo apho i-umbilical cord kunye ne-placenta zijoyina khona;
4. Ugqirha uthatha isampuli encinci yegazi lomntwana malunga ne-2 ukuya kwi-5 ml;
5. Isampulu ithathwa ilebhu iye kuhlolwa.

Ngexesha loviwo, umfazi okhulelweyo unokufumana amahlaba esiswini kwaye ke kufuneka aphumle iiyure ezingama-24 ukuya kuma-48 emva koviwo kwaye angabinabudlelwane obusondeleyo iintsuku ezisi-7 emva kwe-cordocentesis.

Iimpawu ezinje ngokulahleka kolwelo, ukopha kwilungu lobufazi, ukusikwa, ukukhulelwa ngumkhuhlane kunye nentlungu esiswini zisenokuvela emva koviwo. Ukuthomalalisa iintlungu nokungonwabi kunokuba luncedo ukuthatha ithebhulethi yeBuscopan, phantsi kwengcebiso yezonyango.

Yeyiphi imingcipheko ye-cordocentesis

I-Cordocentesis yinkqubo ekhuselekileyo, kodwa inobungozi, njengalo naluphi na olunye uvavanyo olungenelelayo, kwaye ke ugqirha ubuza kuphela xa kukho izibonelelo ezingaphezulu kwengozi yomama okanye yosana. Umngcipheko we-cordocentesis uphantsi kwaye uyalawuleka, kodwa kubandakanya:

• Phantse umngcipheko wokukhulelwa kwesisu;
• Ukuphulukana kwegazi kwindawo apho kufakwe inaliti;
• Ukuhla kwentliziyo yomntwana;
• Ukuqhekeka kwangaphambili kweembumba, ezinokuthi zithande ukuhanjiswa kwangaphambi kwexesha.

Ngokubanzi, ugqirha uyalela i-cordocentesis xa kukrokrelwa isifo semfuza okanye isifo esingakhange sichongwe nge-amniocentesis okanye i-ultrasound.
