I-Dextrocardia yimeko apho umntu azalwe enentliziyo kwicala lasekunene lomzimba, nto leyo ekhokelela kumathuba amaninzi okuba neempawu ezenza kube nzima ukwenza imisebenzi yemihla ngemihla kwaye ezinokunciphisa umgangatho wobomi, njengokufutshane ukuphefumla nokudinwa xa uhamba okanye unyuka izitepsi, umzekelo. Ezi mpawu zivela kuba kwimeko ye-dextrocardia kukho ithuba elikhulu lokuphuhliswa kokungalunganga okufana nokudumba kwemithambo, ukungaphuhli kakuhle kweendonga zentliziyo okanye iivevhe ezibuthathaka.

Nangona kunjalo, kwezinye iimeko, into yokuba intliziyo ikhula kwicala lasekunene ayithethi ukuba kukho naluphi na uhlobo lokuxakeka, njengoko amalungu ekhula ngokuchanekileyo, ke ngoko, akukho mfuneko yokwenza naluphi na uhlobo lonyango.

Ke, kufuneka kuphela ukuba ukhathazeke xa intliziyo ikwicala lasekunene kwaye iimpawu zivela kuthintela ukwenziwa kwemisebenzi yemihla ngemihla. Kule meko, kuyacetyiswa ukuba uye kugqirha wabantwana, kwimeko yomntwana, okanye ugqirha wezentliziyo, kwimeko yomntu omdala, ukuvavanya ukuba ngaba kukho ingxaki kunye nokuqala unyango olufanelekileyo.

Iingxaki eziphambili zentliziyo kwicala lasekunene lomzimba

1. I-ventricle yasekunene eneevenkile ezimbini

Intliziyo eqhelekileyo1. I-ventricle yasekunene eneevenkile ezimbini

Ngamanye amaxesha intliziyo inokukhula ngesiphene ekuthiwa yi-ventricle elungileyo eneendawo ezimbini zokuphuma, apho imithambo emibini yentliziyo iqhagamshela kwi-ventricle efanayo, ngokungafaniyo nentliziyo eqhelekileyo apho umthambo ngamnye udibana khona ne-ventricle.

Kwezi meko, intliziyo ikwanonxibelelwano oluncinci phakathi kwee-ventricles ezimbini ukuvumela igazi ukuba liphume kwi-ventricle yasekhohlo engenakuphuma. Ngale ndlela, igazi elityebileyo kwioksijini lixubana negazi eliphuma kuwo wonke umzimba, libangela iimpawu ezinje:

• Ukudinwa okulula nokugqithisileyo;
• Ulusu oluhlaza kunye nemilebe;
• Izipikili ezishinyeneyo;
• Ubunzima bokufumana ubunzima kunye nokukhula;
• Ukuphefumla okugqithisileyo.

Unyango luhlala lwenziwa ngotyando ukulungisa unxibelelwano phakathi kwee-ventricles ezimbini kunye nokubekwa ngokutsha komthambo we-aortic kwindawo efanelekileyo. Kuxhomekeke kubuzaza bengxaki, kunokuba yimfuneko ukwenza utyando oluninzi ukuze ufumane esona siphumo sihle.

2. Ukungalunganga kodonga phakathi kwe-atria kunye nee-ventricles

Intliziyo eqhelekileyo2. Ukungalunganga kodonga

Ukungalungi kweendonga phakathi kwe-atria kunye ne-ventricles kwenzeka xa i-atria ingahlulwanga phakathi kwabo, kunye ne-ventricles, ebangela ukuba intliziyo ibe ne-atrium enye kunye ne-ventricle enye enkulu, endaweni yeebini. Ukunqongophala kwesahlulo phakathi kwe-atrium nganye kunye ne-ventricle kuvumela igazi ukuba lixube kwaye kukhokelele kuxinzelelo olwandayo kwimiphunga, kubangele iimpawu ezinje:

• Ukudinwa okugqithisileyo, kwanaxa usenza imisebenzi elula njengokuhamba;
• Isikhumba esiluhlaza okanye esincinci;
• Ukungabikho komdla;
• Ukuphefumla ngokukhawuleza;
• Ukudumba kwemilenze kunye nesisu;
• Inyumoniya rhoqo.

Ngokwesiqhelo, unyango lwengxaki lwenziwa malunga neenyanga ezi-3 ukuya kwezi-6 emva kokuzalwa ngotyando ukwenza udonga phakathi kwe-atria kunye nee-ventricles, kodwa, kuxhomekeke kubukhali bengxaki, ugqirha unokuyalela amanye amayeza, anjengehypertensive iziyobisi, kunye ne-diuretics, ukuphucula iimpawu de umntwana afike kwiminyaka apho kukho umngcipheko omncinci wokuhlinzwa.

3. Isiphene ekuvulekeni komthambo we-ventricle efanelekileyo

Ukuvulwa okuqhelekileyo komthambo3. Isiphene ekuvulekeni komthambo

Kwezinye izigulana ezinentliziyo kwicala lasekunene, ivelufa phakathi kwe-ventricle elungileyo kunye nomthambo we-pulmonary isenokungaphuhliswa kakuhle kwaye, ke ngoko, ayivuleki kakuhle, kuthintela ukugqithiswa kwegazi ukuya emiphungeni kunye nokuthintela ioksijini eyaneleyo yegazi. . Ngokuxhomekeke kwinqanaba lokungalunganga kwevalve, iimpawu zinokubandakanya:

• Isisu esidumbileyo;
• Iintlungu zesifuba;
• Ukudinwa kakhulu nokuphelelwa ngamandla;
• Ubunzima bokuphefumla;
• Ulusu olu-purple.

Kwiimeko apho ingxaki iphakathi, unyango lusenokungabi yimfuneko, nangona kunjalo, xa lubangela iimpawu ezingapheliyo nezibi kunokuba yimfuneko ukuthatha amayeza anceda igazi lijikeleze ngcono okanye kwenziwe utyando ukubuyisela ivalve, umzekelo.

4. Imithambo itshintshiselana entliziyweni

Intliziyo eqhelekileyo4. Imithambo etshintshiweyo

Nangona yenye yezona ngxaki zinqabileyo zentliziyo, ingxaki yokutshintsha kwemithambo entliziyweni inokuvela rhoqo kwizigulana ezinentliziyo kwicala lasekunene. Le ngxaki ibangela ukuba i-pulmonary artery idityaniswe kwi-ventricle yasekhohlo endaweni ye-ventricle elungileyo, kanye njengoko i-aortic artery idityaniswe kwi-ventricle elungileyo.

Yiyo ke loo nto, intliziyo eneoksijini ishiya intliziyo idlule ngqo emiphungeni kwaye ayidluli kuwo wonke umzimba, ngelixa igazi elingenayo ioksijini liphuma entliziyweni lize liye ngqo emzimbeni lingafumani ioksijini emiphungeni. Ke, ezona mpawu ziphambili zibonakala kungekudala emva kokuzalwa kwaye zibandakanya:

• Ulusu oluhlaza;
• Ubunzima kakhulu ekuphefumlweni;
• Ukungabikho komdla;

Ezi mpawu zibonakala kwakamsinya emva kokuzalwa kwaye, ke ngoko, kufuneka ukuba uqale unyango ngokukhawuleza kunye nokusetyenziswa kweprostaglandins enceda ukugcina umngxunya ovulekileyo omncinci phakathi kwe-atria yokuxuba igazi, ekhoyo ngexesha lokukhulelwa kwaye ivala kungekudala emva kokubeleka. Nangona kunjalo, utyando kufuneka lwenziwe kwiveki yokuqala yobomi ukubeka imithambo kwindawo efanelekileyo.
