Njengoko uyazi, phantse zonke izitho zomntwana ziqala umsebenzi wazo nangaphambi kokuzalwa kwakhe. Ngoko, intliziyo igqugquzela ukuhamba kwegazi kwiinqanawa, iintso zivelisa umchamo, iimbumba zivelisa ama-hormone.
Umntwana kuphela ngumzimba ongasebenzi kumzimba wesetyhini. Xa beqala ukucwina, bajika baze baqale umsebenzi wabo.
Kungokuzalwa komntwana ukuba intliziyo iqale ukusebenza ngokusebenzayo. Ngoko ke, unina unokukwazi ukubona indlela i-neonatologist, esebenzisa i-stethoscope, iphulaphula intliziyo yesisu esandul 'ukuzalwa ukuba ingabandakanyi imisindo.
Ukwahlula
Yonke ingxolo eyenzeka entliziyweni yeintsana ezisandul 'intsha iyahlukana ibe yintsholongwane kunye nefuthe. Iyokuqala ivele ivele ngenxa yokubunjwa kweengxowa ezongezelelweyo entliziyweni. Kule meko, i-hemodynamics ayiphazamiseki.
Isandi sokugula sisenzeka ngezifo ezifana:
- isiphako sohlulo;
- i-stenosis ye-pulmonary artery ;
- evulekileyo yokuhamba.
Izifo ezikhankanywe ngasentla zihlala zihamba kunye nezibonakaliso ezinzima kakhulu, ngoko ukuxilongwa kwabo akubangele ubunzima obukhethekileyo.
Iimbangela zeentliziyo ziyabubula
Abazali abancinci abaninzi baneliswe ngcamango eyodwa yokuba umntwana wabo osanda kuzalwa unokubhongeka kwentliziyo. Olu loyiko aluqondanga, kuba ukuxilongwa akunakwenziwa nje kuphela ngenxa yesigxina.
Izizathu zomsindo ovalelwa entliziyweni yintsana inokuhluka. Kwiimeko ezininzi, ukuvela kwazo kubangelwa ukutshintshwa kwe-circulation of circulation. Ngoko ebusweni, igazi elixutywe ngokugqithiseleyo liphuma emitanjeni yegazi, edibaniswa neempawu ze-anatomical. Ukuxutywa kwegazi lomgubo kunye nomzimba okhulayo emzimbeni wengane kubangelwa ubukho entliziyweni yeendlela ezintathu zokubala:
- ifowuni;
- umgca wokuhamba;
- ngxakini.
Emva kokuzalwa, bayaqhubeka nokusebenza ixesha elifutshane kwaye njengoko umntwana ekhula. Yingakho, kwiintsuku zokuqala zomsindo wokuphila ungasuswa, kuba ukuqulunqwa kwezi zikhankanywe ngasentla kusasebenza.
I-arterial duct
I-Batalov (i-arterial) i-duct yindlela edibanisa phakathi kwe-trum pulmonary kunye ne-aorta. Ivala iiveki ezimbini emva kokuzalwa komntwana. Kwiimeko ezinqabileyo, ikhula kwiinyanga ezimbini. Ukuba emva kwalesi sihlandlo ngexesha le-ECHO-CG entliziyweni yengane engekafiki, iimvumi ziyafunyanwa, oku kubonisa ukuphuhliswa kwengxaki yokuzalwa komntwana.
Iwindow ye-Oval
Yinto yokwenza i-anatomiki efumaneka kwi-septum eyahlula i-atrium cavity. Ukuvalwa kwayo, njengomthetho, kwenzeka ngenyanga yokuqala kwaye idibaniswa nokuhamba ngokunyuka, ukwandisa ukunyuka kwengcinezelo kwi-atrium yekhohlo. Oomama abaninzi, abo abantwana abasandul 'ukuzalwa baxilongwa ngentliziyo yokugungquthela ngenxa yobuninzi befestile ye-oval, xhalaba malunga nokuba kuyingozi kwaye ukuba kunjalo, bunjani? Akukho nto ixhala ngayo - ifowuni ye-oval ingavaliwe ngokupheleleyo, kwaye ngeminyaka emi-2, kwaye ubukho bayo buyichaphazela i-hemodynamics nayiphi na indlela.
Ihambo ehambayo
Umsebenzi oyintloko wendlela yokutya i-venous ukuxhuma izithambo ezingezantsi ezingenanto kunye neepalini. Iyabonakala ngokukhawuleza emva kokuzalwa, kwaye iguqulwa ibe yintambo equkethe izicubu ezixhamlayo.
Kungakhathaliseki ukuba yintoni imbangela yokuba kwenzeka, nayiphi na isandi entliziyweni kufuneka ixilongwe. Abo bantwana, abanomsindo wabo ngumqondiso wesifo senhliziyo , bafuna ukulandelwa rhoqo. Ukuba kunokwenzeka, ukungenelela kwongqinisiso kwenziwa, nenjongo yalo ukuphelisa isisiphako.
