Ukuskena kwe-RBC yenuzi

Iskena senuzi se-RBC sisebenzisa inani elincane lezinto ezinomsakazo ukumaka (ithegi) amaseli abomvu egazi (ama-RBC). Umzimba wakho bese uskenwa ukubona amaseli bese ulandelela ukuthi ahamba kanjani emzimbeni.

Inqubo yalokhu kuhlolwa ingahluka kancane. Lokhu kuya ngesizathu sokuskena.

Ama-RBC amakwe nge-radioisotope ngezindlela ezi-1 kwezingu-2.

Indlela yokuqala ihilela ukukhipha igazi emthanjeni.

Amaseli abomvu wegazi ahlukaniswe nalo lonke elinye isampula legazi. Amaseli abe esehlanganiswa nezinto ezikhipha imisebe. Amaseli anento enemisebe athathwa njengamakiwe. Ngemuva kwesikhashana ama-RBC amakiwe afakwa komunye wemithambo yakho.

Indlela yesibili ifaka umjovo womuthi. Umuthi uvumela okokusebenza okukhipha imisebe ukuthi kunamathisele kumaseli akho abomvu egazi. Okokusebenza okukhipha imisebe kufakwa emthanjeni emizuzwini engu-15 noma engama-20 ngemuva kokuthola lo muthi.

Ukuskena kungenziwa ngokushesha noma ngemuva kokubambezeleka. Ukuskena, uzolala etafuleni ngaphansi kwekhamera ekhethekile. Ikhamera ithola indawo nenani lemisebe enikezwa amaseli amakiwe.

Kungenziwa uchungechunge lokuskena. Izindawo ezithile eziskeniwe zincike kusizathu sokuhlolwa.

Uzodinga ukusayina ifomu lokuvuma. Ugqoka ingubo yasesibhedlela bese ukhipha ubucwebe noma izinto zensimbi ngaphambi kokuskena.

Ungase uzwe ubuhlungu obuncane lapho inaliti ifakwe ukufakwa igazi noma ukujova umjovo. Ngemuva kwalokho, kungahle kube nokushaywa okuthile.

Ama-x-ray nezinto ezisetshenziswa ngemisebe azibuhlungu. Abanye abantu bangase bangakhululeki ngokulala etafuleni eliqinile.

Lokhu kuhlolwa kuvame ukwenziwa ukuthola indawo yokuphuma kwegazi. Kwenziwa kubantu abalahlekelwe yigazi kukholoni noma kwezinye izingxenye zomgudu wamathumbu.

Ukuhlolwa okufanayo okubizwa nge-ventriculogram kungenziwa ukuhlola ukusebenza kwenhliziyo.

Ukuhlolwa okujwayelekile akubonisi ukuphuma kwegazi okusheshayo okuphuma emathunjini.

Kukhona ukopha okusebenzayo okuvela emgodini wamathumbu.

Izingozi ezincane zokutholwa kwegazi zifaka:

• Ukuquleka noma uzizwe unekhanda elincane
• I-hematoma (ukuqoqwa kwegazi ngaphansi kwesikhumba)
• Ukutheleleka (ingozi encane noma kunini lapho isikhumba siphukile)

Kuyaqabukela kakhulu, umuntu angaba ne-allergen yokusabela ku-radioisotope. Lokhu kungafaka i-anaphylaxis uma umuntu ezwela kakhulu entweni leyo.

Uzokwambulelwa inani elincane lemisebe evela kwi-radioisotope. Izinto zonakala ngokushesha okukhulu. Cishe yonke i-radioactivity izobe ihambile kungakapheli izinsuku ezi-1 noma ezi-2. Isithwebuli asikhiphi imisebe.

Izikena eziningi zenuzi (kufaka phakathi ukuskena kwe-RBC) azinconyelwa abesifazane abakhulelwe noma abancelisayo.

Izikrini zingadinga ukuphindwa ngaphezulu kwezinsuku ezi-1 noma ezi-2 ukuthola ukopha emathunjini.

Ukuskena ukopha, umake i-RBC scan; Ukopha - ukuskena kwe-RBC
