Izingane zinendlela engavamile yokukhula esibelethweni sikamama. Banezidingo ezifanayo, mayelana nokudla kwabo kanye ne-oxygen, kodwa abangakasebenzisi isimiso sokugaya noma sokuphefumula. Amaphaphu azokwakheka phakathi nesikhathi sokukhulelwa, kodwa ngeke bawasebenzise baze bazalwe, yingakho sizibuza indlela izingane eziphefumula ngayo ngaphakathi kwesisu sowesifazane okhulelwe.
Siyazi umbilical cord, kodwa izikhathi eziningi asazi ukuthi yimiphi imisebenzi ebonakala esibelethweni sowesifazane okhulelwe. Leli shubhu eliguquguqukayo lihlanganisa umbungu ku-placenta futhi lizoyisiza ithole imisoco eyidingayo kanye nomoya-mpilo. Kule migqa elandelayo sichaza kabanzi ukuthi iyimisebenzi kanjani nokuthi inamuphi ukubaluleka okubalulekile ekukhuleni kwengane.
Ukuphefumula kwengane ngaphakathi kwesisu sowesifazane okhulelwe?
Ingane noma i-fetus idinga ukudla nomoya-mpilo ukuze sikhule futhi sithuthuke. Awukwazi ukukwenza njengoba sazi, kodwa uthatha lezi zinto ngenkaba.
Inkaba ixhuma ingane ne-placenta., i-placenta yakhe nayo ixhunywe esibelethweni sikamama. I-fetus ayisebenzisi amaphaphu ayo ukuze iphefumule, kodwa yenza kanjalo ngentambo yenkaba. Umoya-mpilo ugeleza emthanjeni wenkaba, ukuze ufinyelele inhliziyo bese usabalaliswa kuwo wonke umzimba.
Ngemuva igazi elingenawo umoya-mpilo buya ngenkaba ukuya esibelethweni, lapho kuthatha umoya-mpilo futhi ukuze ubuyele enganeni. Ngalesi simiso, ukuphathwa ngendlela efanele komoyampilo odingekayo kulawulwa, ngaphandle kokuba kube nensalela noma yiluphi uhlobo lokugcwala kwamanzi.
Imisebenzi yezintambo zombilical
El intambo yombilical ixhuma i-fetus ku-placenta. Kuwuhlobo lomgudu oguquguqukayo owondla ingane nge-oxygen nezakhi. Inesilinganiso esingaba ngu-56 cm. Ifomu nokusebenza kwayo kuyingxenye yokuthuthukiswa kokukhulelwa konke, ngoba ngemithambo emibili ye-umbilical umntwana angondliwe ngendlela efanele.
Amaphaphu akheka ngesikhathi sokukhulelwa
- Amaphaphu omntwana aqala ukukhula evikini lesihlanu lokukhulelwa, lapho zikhula kancane kancane zibe i-alveoli.
- Phakathi kwamaviki 7 kuya ku-16 isihlahla se-bronchial kanye nezakhiwo ezisekela amaphaphu (uqwanga, imithambo yegazi nemisipha) ziqala ukwakha.
- ngeviki 13 umntwana uzoqala ukuhogela uketshezi oluncane lwe-amniotic futhi uzolukhipha, kuzoba yisigaba sakhe esincane sokulungiselela.
- phakathi amasonto 17 kuya ku-27 i-bronchi izoqala ukuhlukana ibe ama-bronchioles futhi lapho i-pneumocyte ne-surfactant iqala ukuvela, into evimbela i-alveoli ekunamatheleni lapho ihogela umoya.
- the isonto 28 kuya ku-36 Kuvela i-alveoli yokuqala, ezokwenziwa ibe semthethweni kanye nesakhiwo sonke samaphaphu kuze kube yisikhathi sokuzalwa.
Amaphaphu ayisitho sokugcina esiqeda ukukhula ngesikhathi sokukhulelwa. njengoba inkaba ithatha indawo yokusebenza kwayo ngaphandle kwenkinga. Ingane ihlala ngaphansi kwamanzi ngaphansi kwendawo yasemanzini ebizwa ngokuthi i-amniotic fluid nalapho amaphaphu akho eyogcwala khona lolu ketshezi.
Ukuphazamiseka komoyampilo ngesikhathi sokukhulelwa
Ukuphazamiseka komoyampilo kungenzeka ngesikhathi sokukhulelwa. Enye yezimbangela kungaba ukufinyela okuqine ngokweqile noma uma kukhona a i-hyperstimulation yesibeletho. Ukusetshenziswa okungalungile noma okungafanele kwe-oxytocin kungadlala indima ebalulekile, kube yimbangela yaleli qiniso.
Ngesikhathi sokukhulelwa kungadala futhi ukuphazamiseka kwendlela ye-oxygen emgwaqeni placenta, kungaba ngenxa ye-placenta previa, ukuphuma kwe-placenta, izifo ezibangelwa amagciwane, i-anemia, noma ukwakheka kwe-hemoglobin engavamile. Ukuphazanyiswa kwe-oksijini ngentambo yombilical kungaba enye yezimbangela, lapho kuyodingeka khona funda ngokujulile ukuthi kungani kwenzeka.
Kuze kube yilapho umntwana ezalwa, isimangaliso esilindelwe isikhathi eside ngeke senzeke. Kuze kube yilapho idlula emgodini wokuzalwa noma ibelethwa ngokuhlinzwa, ikhala lakho nomlomo akukakalungeli ukuvuleka futhi donsa umoya okokuqala ngqa. Yilapho uhosha umoya futhi amaphaphu akho azokhula, okubangela ukuba umoya-mpilo uhanjiswe ngegazi lakho ukuze uphile.
