Masifunde nge-Swan-Ganz Catheterization, ejonge ngaphakathi entliziyweni.

Xa ugqirha wakho ekrokrela ukuba unengxaki yokuphefumla okanye ukuba unengxaki yentliziyo, bafuna ukwazi ukuba kwenzeka ntoni entliziyweni yakho, akunjalo? Ngamaxesha anje, namhlanje siza kuthetha ngesixhobo esikhethekileyo esisetyenziselwa ukufumana ulwazi oluchanekileyo malunga nendlela intliziyo yakho esebenza ngayo. Sibizwa ngokuba yiSwan-Ganz Catheter. Usenokuba awuzange uve ngeli gama, kodwa luvavanyo olubaluleke kakhulu.

Ngamafutshane, yintoni le mbhobho yeSwan-Ganz?

I-catheter yeSwan-Ganz yityhubhu ebhityileyo neguquguqukayo (i-catheter). Ikwabizwa ngokuba yi-'pulmonary artery catheter'. Yicinge njengetyhubhu encinci enetyhubhu ezine ezincinci ngaphakathi kuyo. Ngayinye kwezi tyhubhu inomsebenzi owahlukileyo.

Isetyenziswa kakhulu ukulinganisa ulwazi malunga nokusebenza kwenkqubo yakho yokujikeleza kwegazi, oko kukuthi, indlela igazi elihamba ngayo (i-hemodynamics).

Ezi zizinto ezenziwa ziinxalenye ezahlukeneyo (iiports) zalo mbhobho:

• Ulwelo okanye amayeza afunekayo anokunikwa ngqo entliziyweni.
• Uxinzelelo lwegazi ngaphakathi kwamagumbi ahlukeneyo entliziyo nangaphakathi kwemithambo yegazi lunokulinganiswa ngokuchanekileyo.
• Xa le tube ifakwa kumthambo oyintloko othwala igazi ukuya emiphungeni (umthambo we-pulmonary), isetyenziselwa ukufutha ibhaluni encinci enceda ukuyikhokelela kwindawo efanelekileyo.
• Isampuli yegazi ingathathwa nakwimithambo yegazi ethwala igazi ukuya emiphungeni.

Yintoni abayaziyo oogqirha kule tube?

Olu vavanyo lunokunika ugqirha wakho umfanekiso ocacileyo wokuba intliziyo yakho iphilile kangakanani. Kufana nokujonga ngaphakathi entliziyweni yakho.

Ingaba le ndlela isasetyenziswa?

Ewe, ngokuqinisekileyo. Le ndlela isathathwa njengeyona "mgangatho wegolide" wokufumana ulwazi oluchanekileyo malunga noxinzelelo olungaphakathi kwimithambo yentliziyo nemiphunga.

Nangona kunjalo, ukusetyenziswa kwale ndlela kuye kwehla kutshanje, ingakumbi kwizigulane ezigula kakhulu kwiindawo zokhathalelo oluphezulu. Oku kungenxa yokuphuhliswa kweendlela ezingabangeli bungozi kangako, ezingangenisi gazi ezifana ne-"Echocardiography" (ukuskena kwentliziyo) ezinokufumana ulwazi ngaphandle kokungena emzimbeni.

Ngubani ofanele athathe olu vavanyo?

Ugqirha wakho angacebisa olu vavanyo ukuba ukrokrela okanye uyazi ukuba unenye yezi meko zilandelayo zonyango:

• Ubunzima bokuphefumla
• Ukuhlaselwa yintliziyo
• Ukumelwa yintliziyo
• Ukothuka kwentliziyo
• Uxinzelelo lwegazi oluphezulu lwemiphunga
• Izingqisho zentliziyo ezingaqhelekanga
• Ukuxhuzula kwemithambo yegazi (pulmonary embolism)
• I-tamponade yentliziyo
• Iimeko zentliziyo zokuzalwa

Le ndlela ikwasetyenziselwa ukufumana ulwazi malunga nokusebenza kwentliziyo ngaphambi nasemva kotyando olukhulu, njengokufakelwa intliziyo okanye ukufakwa kwesixhobo sokuncedisa i-ventricular yasekhohlo.

Masifunde kancinci ngendlela olu vavanyo oluqhutywa ngayo.

Olu vavanyo ludla ngokwenziwa kwilabhoratri ye-cardiac catheterization yesibhedlele. Akukho mfuneko yokukhathazeka ngale nto. Oogqirha baya kuzama ukukugcina ukhululekile kangangoko kunokwenzeka.

Kwenzeka ntoni ngaphambi kovavanyo?

1. Ugqirha uza kukuchazela ngokucacileyo ukuba kutheni kwaye kwenziwa njani olu vavanyo.

2. Ukuba usela amayeza, uza kubuzwa ukuba kufuneka uwayeke na ngaphambi kovavanyo.

3. Uya kucetyiswa ukuba ungatyi okanye usele iiyure ezimbalwa ngaphambi kovavanyo.

4. Imvume yakho ebhaliweyo (imvume) yokwenza olu vavanyo iya kufumaneka.

5. Uza kulaliswa ebhedini ekhethekileyo.

6. Uza kunikwa amayeza ngomthambo (`IV`) ukuze akuphumze kwaye akunike amandla.

Ngexesha lovavanyo

Okokuqala, ugqirha uza kucoca kakuhle indawo apho kuza kufakwa khona ityhubhu (ngesiqhelo entanyeni, esifubeni, okanye emlenzeni) aze ayivale loo ndawo ukuze ungabi nantlungu. Emva koko, ityhubhu yeSwan-Ganz ifakwa ngononophelo kumthambo omkhulu ize ifakwe kwi-ventricle yasekunene yentliziyo iye kumthambo oyintloko okhokelela emiphungeni (pulmonary artery).

Nje ukuba lonke ulwazi olufunekayo lulinganiswe, ityhubhu isuswa ngononophelo.

Emva kovavanyo

Emva kokuba ityhubhu isusiwe, kuya kufakwa ibhandishi okanye iplasta kwindawo leyo ukunqanda nakuphi na ukopha. Ukuba ityhubhu ifakiwe emlenzeni wakho, uya kucelwa ukuba ulale ebhedini iiyure ezimbini ukuya kwezintandathu. Kuqhelekile ukubona inxeba elincinci apho ityhubhu ifakiwe khona. Oku kuya kuphela emva kweveki enye okanye ezimbini.

Ngaba kukho umngcipheko koku?

Le yeyona nto ibalulekileyo. Umngcipheko weengxaki zokufaka ityhubhu yeSwan-Ganz uphantsi kakhulu . Oko kukuthi, ngaphantsi kwe-0.5%. Oko kuthetha ukuba ukuba oku kwenziwa kubantu abangama-200, umntu omnye kuphela oza kuba nengxaki. Kodwa, njengakweyiphi na inkqubo yezonyango, kukho umngcipheko omncinci kakhulu.

• Usulelo kwindawo efakwe kuyo ityhubhu.
• Iqamza lomoya lingena emthanjeni wegazi.
• Ukuba kusetyenziswa umthambo wesifuba (umthambo we-subclavian), kukho ithuba elincinci kakhulu lokonakala kwemiphunga.
• Ukubetha kwentliziyo okungaqhelekanga.
• Ukonakala kodonga lwentliziyo, ivalvu, okanye umthambo (oku kunqabile kakhulu).

Ukuba unale mpawu, fowunela ugqirha wakho ngokukhawuleza.

Ukuba ufumana nayiphi na kwezi zinto zilandelayo xa ubuyela ekhaya emva kovavanyo, yazisa ugqirha wakho ngoko nangoko.

• Ukuba inxeba apho ityhubhu ifakwe khona liyadumba okanye ukuba igazi okanye olunye ulwelo luvuza kulo .
• Ukuba kukho ukungakhululeki okanye ukudumba emlenzeni apho ityhubhu ifakwe khona.
