I-Venipuncture

IVenipuncture ukuqoqwa kwegazi emthanjeni. Kuvame ukwenziwa ukuhlolwa kwelabhorethri.

Isikhathi esiningi, igazi likhishwa emthanjeni ongaphakathi endololwaneni noma ngemuva kwesandla.

• Isiza sihlanzwa ngemithi yokubulala amagciwane (isinqandakuvunda).
• Ibhande lokunwebeka lifakwa engalweni ephezulu ukufaka ingcindezi endaweni. Lokhu kwenza umthambo ugcwale igazi.
• Kufakwa inaliti emthanjeni.
• Igazi liqoqelwa esitsheni esingangeni moya noma ithubhu enamathiselwe enalithini.
• Ibhande lokunwebeka lisusiwe engalweni yakho.
• Inaliti iyakhishwa futhi indawo imbozwe ngebhandeshi ukuze kunqandwe ukopha.

Ezinsaneni noma ezinganeni ezincane, ithuluzi elibukhali elibizwa ngokuthi i-lancet lingasetshenziselwa ukubhoboza isikhumba nokusenza siphume igazi. Igazi liqoqa emgqeni wesilayidi noma wokuhlola. Ibhandishi lingabekwa ngaphezu kwendawo uma kukhona ukopha.

Izinyathelo odinga ukuzithatha ngaphambi kokuhlolwa zizoya ngohlobo lokuhlolwa kwegazi onalo. Ukuhlolwa okuningi akudingi izinyathelo ezikhethekile.

Kwezinye izimo, umhlinzeki wakho wezokunakekelwa kwempilo uzokutshela uma udinga ukuyeka ukuthatha noma yimiphi imithi ngaphambi kokuhlolwa noma uma udinga ukuzila ukudla. Ungayeki noma ushintshe imithi yakho ngaphandle kokukhuluma nomhlinzeki wakho kuqala.

Ungase uzwe ubuhlungu obuncane noma isitinyela lapho kufakwa inaliti. Ungase futhi uzizwe ushaywa yisiza ngemuva kokukhishwa kwegazi.

Igazi lakhiwe izingxenye ezimbili:

• Uketshezi (i-plasma noma i-serum)
• Amaseli

I-Plasma yingxenye ewuketshezi yegazi egazini eliqukethe izinto ezinjenge-glucose, i-electrolyte, amaprotheni namanzi. I-Serum yingxenye ewuketshezi esele ngemuva kokuthi igazi livunyelwe ukugoqa kushubhu lokuhlola.

Amaseli egazini afaka amaseli abomvu egazi, amangqamuzana amhlophe egazi nama-platelets.

Igazi lisiza ukuhambisa umoya-mpilo, izakhamzimba, imfucuza, nezinye izinto emzimbeni. Kuyasiza ukulawula ukushisa komzimba, ibhalansi yoketshezi, kanye ne-acid-base balance yomzimba.

Ukuhlolwa egazini noma ezingxenyeni zegazi kunganikeza umhlinzeki wakho izinkomba ezibalulekile ngempilo yakho.

Imiphumela ejwayelekile iyahluka ngokuhlolwa okuthile.

Imiphumela engajwayelekile iyahluka ngokuhlolwa okuthile.
