I-hypoxia ye-Fetal iyenzeka ngokuntuleka njalo kwe-oksijini okunikezwa kwezicubu nezitho zomntwana. Ngokwezibalo, i-hypoxia engapheli yesisu ivela ku-10.5% wabesifazane abakhulelwe. I-hypoxia engapheli ikhula kancane kancane, ngakho-ke ingane ikwazi ukuvumelanisa nokuntuleka komoya okwenziwe njalo.
I-fetal hypoxia - izimbangela
Isizathu se-hypoxia esingapheli singase sibe nesifo se-anemia besifazane okhulelwe, isifo sofuzo (izifo zenhliziyo, izifo zokuphefumula, ukudakwa okungapheli, njll) nokuphulwa kwegazi lokuphuma kwegazi (ngenxa ye-pre-eclampsia, impikiswano ye-rhesus-factor noma iqembu legazi, i-perenashivanii). Izimpawu zomtholampilo ze-hypoxia ezingapheli zesisu ziyashintsha emvuthweni wokunyakaza kwesisu; ekuqaleni ziba njalo, futhi ukwanda kwe-oksijeni yindlala kanye nokukhathala kwezinqubo zokubuyisela izithelo zezithelo ziba njalo. Ukunciphisa inani lokunyakaza kuya ku-3 ngehora kusho ukuthi ingane ihlupheka futhi owesifazane udinga ukubonana nodokotela ngokushesha. Ukwenza izifundo ezinjenge-cardiotocography ne-dopplerometry kusiza ukucacisa ukuxilongwa.
Ungakuvikela kanjani hypoxia ye-fetal?
Ukuze ugweme imiphumela ebangelwa ukuntuleka okungapheli kwe-oxygen, udinga ukuqeda imbangela. Ngezimo eziphuthumayo zezinhliziyo zenhliziyo, izinhlelo zokuphefumula nezama-excretory, i-pre-eclampsia yezinga eliphansi, i-anemia ye-1 degree, ukwelashwa kungaba ekhaya. Ngezimo ezikhokhelwayo nezikhokhelwayo, ukwelashwa esibhedlela kunconywa kakhulu.
I-hypoxia yesisu engapheli - imiphumela
Njengoba kunesifo esincane se-oksijini, isitho somzimba wesisu singakwazi ukwakha izindlela zokuzivumelanisa ngokwandisa izinga lokushaya kwenhliziyo kuya ku-150-160 beats ngomzuzu, okwandisa amandla oksijini wegazi, isakhiwo esikhethekile se-hemoglobin, nokukhula komzimba. Ukuntuleka okungapheli oksijini kungabangela ukulibaziseka ekuthuthukiseni ingane emfantwini, ukulimala kwezinhlelo ze-cardiovascular and nervous systems.
