Idivayisi yokusiza ye-Ventricular

Amadivayisi we-Ventricular assist (VADs) asiza inhliziyo yakho ukuthi ipompe igazi lisuka kwelinye lamagumbi amakhulu okupompa liye kuwo wonke umzimba wakho noma kolunye uhlangothi lwenhliziyo. La mapampu afakwa emzimbeni wakho. Ezimweni eziningi zixhunywe kwimishini engaphandle komzimba wakho.

Idivayisi yokusiza ye-ventricular inezingxenye ezi-3:

• Iphampu. Iphampu linesisindo esingamakhilogremu ayi-1 kuye kwayi-2 (0.5 kuya ku-1 kilogram). Ibekwe ngaphakathi noma ngaphandle kwesisu sakho.
• Isilawuli se-elekthronikhi. Isilawuli sifana nekhompyutha encane elawula ukuthi iphampu isebenza kanjani.
• Amabhethri noma omunye umthombo wamandla. Amabhethri athwalwa ngaphandle komzimba wakho. Zixhunywe kupompo ngentambo engena esiswini sakho.

Uma une-VAD efakiwe efakiwe, uzodinga i-anesthesia ejwayelekile. Lokhu kuzokwenza ulale futhi ungabi nezinhlungu ngesikhathi senqubo.

Ngesikhathi sokuhlinzwa:

• Udokotela ohlinzayo wenhliziyo uvula maphakathi nesifuba sakho ngokusikwa okuhlinzwa bese ehlukanisa ithambo lakho lesifuba. Lokhu kuvumela ukufinyelela enhliziyweni yakho.
• Ngokuya ngepompo esetshenzisiwe, udokotela ohlinzayo uzokwenza isikhala sepompo ngaphansi kwesikhumba sakho nezicubu engxenyeni engenhla yodonga lwesisu sakho.
• Udokotela ohlinzayo uzobe ebeka ipompo kule ndawo.

Ishubhu lizoxhumanisa ipompo nenhliziyo yakho. Enye ithubhu izoxhuma iphampu ku-aorta yakho noma kwenye yemithambo yakho emikhulu. Enye ithubhu izodluliswa esikhunjeni sakho ukuxhuma iphampu kusilawuli nakumabhethri.

I-VAD izothatha igazi kwi-ventricle yakho (elinye lamagumbi amakhulu okupompa enhliziyo) ngebhubhu eholela empompini. Lapho-ke le divayisi izokhipha igazi libuyele komunye wemithambo yakho nasemzimbeni wakho.

Ukuhlinzwa kuvame ukuthatha amahora amane kuya kwayisithupha.

Kunezinye izinhlobo zama-VADs (abizwa ngamadivayisi we-percutaneous ventricular assist) angabekwa ngamasu angahlaseli kangako okusiza i-ventricle yangakwesokunxele noma yesokudla. Kodwa-ke, lokhu ngokuvamile akukwazi ukuhlinzeka ngokugeleza okuningi (ukwesekwa) njengalokho okufakelwe ngokuhlinzwa.

Ungadinga i-VAD uma unokwehluleka okukhulu kwenhliziyo okungalawulwa ngemithi, amadivayisi wokuhamba, noma ezinye izindlela zokwelapha. Ungayithola le divayisi ngenkathi usohlwini lokulinda ukufakelwa inhliziyo.Abanye abantu abathola i-VAD bagula kakhulu futhi kungenzeka ukuthi sebevele besemshinini wokusekela inhliziyo-lung.

Akuwona wonke umuntu onokwehluleka okukhulu kwenhliziyo ongumuntu ofanelekela le nqubo.

Izingozi zalokhu kuhlinzwa yilezi:

• Amahlule egazi emilenzeni angahamba aye emaphashini
• Amahlule egazi akha kule divayisi futhi angaya kwezinye izingxenye zomzimba
• Izinkinga zokuphefumula
• Isifo senhliziyo noma isifo sohlangothi
• Ukungezwani komzimba nemithi yokubulala izinzwa esetshenziswa ngesikhathi sokuhlinzwa
• Izifo
• Ukopha
• Ukufa

Abantu abaningi bazobe sebesesibhedlela vele bezolashwa ngokuhluleka kwenhliziyo yabo.

Iningi labantu abafakwa kwi-VAD bachitha kusuka ezinsukwini ezimbalwa kuya ezinsukwini ezimbalwa egumbini labagula kakhulu (i-ICU) ngemuva kokuhlinzwa. Ungahlala esibhedlela isonto noma ngaphezulu ngemuva kokufakwa kwepompo. Ngalesi sikhathi uzofunda ukuthi unganakekela kanjani ipompo.

Ama-VAD amancane angenakudalelwa iziguli ezihamba ngezinyawo futhi lezo ziguli zidinga ukuhlala e-ICU isikhathi sokusetshenziswa kwazo. Ngezinye izikhathi zisetshenziswa njengebhuloho le-VAD yokuhlinzwa noma ukutakula kwenhliziyo.

I-VAD ingasiza abantu abanesifo senhliziyo ukuthi baphile isikhathi eside. Kungasiza futhi ukuthuthukisa ikhwalithi yempilo yeziguli.
