Ukubeleka kwiiveki ezingama-32

Nayiphi na ibhinqa elindele ukuba umntwana azalwe ngokukhawuleza ukholelwa ixesha elithile xa embona okokuqala. Njengoko uyayazi, ubude bexesha lokuxhaswa ngamaviki ezingama-40. Kodwa akusoloko umntwana eshiya umzimba womama ngexesha elinjalo. Ngokuqhelekileyo, kukho oko kuthiwa ukuzalwa kwangaphambi kokuzalwa ngaphambi kokuba iiveki ezingama-37 zesisu. Masiqwalasele ngakumbi le ngxaki kwaye sikuxelele ngemingcipheko engenzeka ngexesha lokubeleka kwiiveki ezingama-32 zokukhulelwa.

Ngenxa yento umntwana azalwa ngayo ngaphambi komhla wokugqibela?

Enyanisweni, izizathu zokuzalwa komntwana, kuninzi kakhulu. Nangona kunjalo, kwiimeko ezininzi, ukuzalwa ngaphambi kokuzalwa kungenxa yokufumaneka kwezi zifo ezilandelayo:

• encinci okanye, ngokuchaseneyo, i-polyhydramnios;
• ukwanda komzimba kubasetyhini abakhulelweyo;
• izifo ezithathelwanayo kunye neentsholongwane;
• uphuhliso lwe- hypoxia yomntwana;
• sisifo somzimba;
• izifo zofuzo;
• Ulwaphulo lweRhesus;
• msebenzi womzimba.

Yintoni ekhokelela ekuzalweni kwangaphambi kweveki 32?

Kufuneka ukuba uqaphele ukuba kwiimeko ezininzi kunokwenzeka ukuba ushiye umntwana ophelele kwaye ophilileyo. Nangona kunjalo, ngaphandle kweengxaki ezinqabileyo.

Okokuqala, kuyimfuneko ukuqaphela ukungakhangeki kokuhambelana kwenkqubo yokuphefumula yomntwana. Umqhubi osebenzayo, ovimbela i-alveoli ukuba ingawa phantsi emiphakeni kwaye imele ifune ukuphefumla, iqala ukuhlanganiswa kwiveki ye-20-24 yokukhula komntwana. Kodwa ngelo xesha, ukuvuthwa okupheleleyo kwesi simiso kubonakala kuphela kwiiveki ezingama-36.

Yingakho ubambano kwiveki ye-32 yokukhulelwa akunakuyenza ngaphandle kokuphulwa, okubizwa ngokuba yi-ventilation-perfusion ratio kwimiphunga. Le nto ibangela iingxaki ezifana ne-hypoxia, ukunyuka kwengqondo (ukwanda kwinqanaba le CO2 egazini), i-metabolic-breathing acidosis (ukunciphisa igazi pH). Kwimeko enjalo, umntwana ufuna unyango lwengxamiseko ngokuphuphuma umoya.

Ukuba nemiphumo engapheliyo yokubeleka kwiiveki ezingama-32 kunokubanjelwa ekunciphiseni kwimisebenzi yokhuseleko lomzimba, elinezifo ezithintekayo zentsholongwane kunye nezifo ezithathelwanayo, ubunzima obuncinane bomntwana (ngokuqhelekileyo i-1800-2000 g). Eyona nto, iinkqubo zentsana kunye nezitho zilungele ukusebenza ngokuqhelekileyo.

Ngokwahlukileyo, kuyimfuneko ukuthetha ngemiphumo yomsebenzi wokuqala kwisonto lama-32 lokukhulelwa, okungafumaneka kwintokazi. Eyokuqala, kwiimeko ezinjalo, ingozi yokuphuma kwe-intrauterine yanda. Ngelo xesha, ukusuleleka kwenkqubo yokuzala akukwazi ukupheliswa ngokupheleleyo. Ukunikezelwa kwezi zinto, njengommiselo, ibhinqa ubuncinane ubuncinane kwiintsuku ezili-10 kwisebe leposi emva kokulawulwa koogqirha.
