Yintoni i-Cardiopulmonary Bypass okanye i-Heart Lung Bypass?
Yintoni iCardiopulmonary Bypass Machine (CBM)?
Umshini we-cardiopulmonary bypass machine (CBM) uyaziwa ngokuba ngumshini we-lung-pulp machine. Yisisombululo esenza umsebenzi wokubonelela ngegazi (kunye ne-oksijeni) emzimbeni xa intliziyo imisiwe kwinkqubo yokupasa.
Kwiimeko ezininzi, umatshini usetyenziselwa ukwenza iinkqubo ezinzulu ezifuna ukuba intliziyo igqitywe.
Izigulane zisepom kuphela nje ngokuba kuthatha ixesha lokuthintela intliziyo ekubetheni, ukuzalisa intliziyo evulekileyo okanye inkqubo kwimiphunga, kwaye uqale kwakhona intliziyo.
Kutheni iCardiopulmonary Bypass isetyenzisiwe?
Ukumisa intliziyo ngaphandle kokulimaza isigulane, igazi le-oxygen kufuneka liqhubeke lijikeleza ngomzimba ngexesha lotyando ngaphandle kokuyeka. Umpompo we-cardiopulmonary bypass umsebenzi wentliziyo, ukupompa igazi ngomzimba, nokuqinisekisa ukuba izicubu zomzimba zithola umoya-mpilo abazifunayo. Umatshini wongeza i-oksijini egazini ngelixa esithatha isenzo sokuphambanisa intliziyo, ukubeka endaweni yomsebenzi wemiphunga.
I-CBM isetyenziselwa izizathu ezibini eziphambili. Isizathu esiqhelekileyo kukuba intliziyo inokumiswa ukuhlinzwa. Ezinye iintlobo zonyango zomzimba zazingenakukwazi ukwenza ngokubetha kwentliziyo, njengoko utyando lwaluya kwenziwa "ekujoliswe kuyo" okanye kwakuya kubakho ukulahleka kwegazi.
Umzekelo omkhulu wolu hlobo lwenkqubo yokufakelwa kwentliziyo - intliziyo yesigulane kufuneka isuswe emzimbeni ukuze intliziyo ezinikezelweyo ingeniswa. Ngaphandle kwepom ukuba ithatyathele isenzo senhliziyo, ukutshintsha kwentliziyo kwakungenakwenzeka.
Kwakunjalo nokuhlinzwa kwamaphaphu, kufuneka kubekho indlela yokwenza i-oxygen igazi xa imiphunga ingakwazi.
Inkqubo yokufakelwa kwemiphunga idinga indlela enye yokuphefumula ngegazi xa imiphunga ingakwazi, kodwa intliziyo ingaqhubeka ibetha ngexesha le nkqubo.
Kwezinye izigulane, ipompi ayisetyenziswanga ukuhlinzwa, kodwa ukukunceda ukugcina isigulane siphila xa befumana ukungaphumeleli kwentliziyo okuya kuba ubomi buphela. Kwezinye iimeko ezinqabileyo, ukukhubazeka kwentliziyo kungagcinwa kwipom ukuxhasa isigulane kude kube yintliziyo yokutshintsha .
I-Cardiopulmonary Bypass isebenza njani?
Udokotela ogqirha unamathela kwi-tubing ekhethekileyo kwisitya esikhulu segazi (njengokuqala i-IV enkulu) evumela ukuba igazi le-oksijini eliphelile liphume emzimbeni kwaye liye liye kumatshini ogqithisiweyo. Kulapho, umatshini u-oxygenates igazi kwaye uyabubuyisela emzimbeni ngokusebenzisa isethi yesibini ye-tubing, nayo iqhotyoshelwe emzimbeni. Ukupompa okuqhubekayo komatshini kuqhube igazi le-oxygen emzimbeni, njengentliziyo.
Ukubekwa kweethubhu kuchongwa ngokukhetha kwonyango. Iibhubhu mazibekwe kude kwisiza sokuhlinzwa ukuze zingaphazamisi umsebenzi wesigqirha, kodwa zifakwe kwisitya segazi esikhulu ngokwaneleyo ukulungiselela ukubheja kunye nokuxinzelelo kwepompo. Ezi zimbini ziqinisekisa ukuba igazi liphuma emzimbeni ngaphambi kokuba lifike entliziyweni kwaye libuyele emzimbeni emva kwentliziyo, unike ugqirha indawo enokuhlala kunye negazi.
Itheyibhile yesithathu ifakwe ngokufutshane okanye ngqo kwi ntliziyo, kodwa ayixhunyiwe kwi-CPM. Isetyenziselwa ukuchukumisa intliziyo nge cardioplegia, isisombululo se potassium esima intliziyo. Xa i-cardioplegia iqalisa ukusebenza, i-CBM iqaliswa kwaye ithatha umsebenzi wentliziyo nomphunga.
Ngubani oqhuba umshini weCardiopulmonary Bypass?
Umntu oqhuba i-cardiopulmonary bypass pump ubizwa ngokuba ngu-perfusionist. I-Perfusionists inesidanga se-bachelor kwi-intanethi echaphazelekayo nempilo, emva koko iqhube iminyaka engaphezu koko emibini yokuqeqesha imfundo njengomngcipheko. Abanye abahlaziyiyo bathatha uvavanyo lokuba yi-clinic perfusionist eqinisekisiweyo, efana nogqirha ebhodi eqinisekisiwe kwi-specialty.
Izingozi zeCardiopulmonary Bypass
Ubungozi bokuba kwintliziyo kunye nomphunga weemiphunga zibandakanya ama-clots egazi, ukuphuma kwegazi emva kokuhlinzwa, ukulimala kwintlanzi ye-phrenic, ukulimala kweentso ezinzulu nokunciphisa umphunga kunye / okanye umsebenzi wentliziyo. Le mngcipheko iyancipha ngamaxesha amancinci kwipompo kwaye yanda ngamaxesha ompompo.

ILizwi Ku:
Naliphi na inkqubo efuna ukusetyenziswa komshini we-cardiopulmonary bypass umthambo omkhulu kwaye kufuneka uthathwe ngokungathí sina. Nangona iingozi ezinxulumene nale nkqubo zinokubaluleka, ezi zonyango zi nookugcina ubomi okanye ukuphucula ubomi.
Xa kunokwenzeka, kubalulekile ukuthatha ixesha lokuxoxa ngemingcipheko kunye nemivuzo yenkqubo kunye nezinye iindlela zokuhlinzwa phambi kokuba wenze isigqibo.
