Ukukhulelwa kweveki ezingama-28 - uphuhliso lomntwana

Kwiiveki ezingama-28 ( iinyanga ezi-7 ezithweleyo ), umntwana sele eseneminyaka engama-1 ubudala, kodwa ngezinye izihlandlo zokubeletha kwangaphambi kokuzalwa kwangoku kwenzeka ngeli xesha. Kwaye ngokulungelelaniswa kokubeleka kokubeleka kunye nokunyamekela kokubeleka emva kokubeleka kwisebe elikhethekileyo kwiintsana zangaphambi kwangoko, umntwana unamathuba onke okuphila kwaye akhule kwaye aphuhlise kakuhle ngokungabikho kwintsholongwane ebuncinci. Ukususela ekubelethweni ngeli xesha akuqhelekanga, ukuphuhliswa kwe-fetus ngeli xesha kuyaziwa.

Iveki yama-28 yokukhulelwa kunye nobukhulu bomntwana

Ukuphakama komntwana ozalwe ngeli xesha kungama-33-38 cm, ubunzima bomntwana bukhula kwiiveki ezingama-28 zokukhulelwa phakathi kwe-1100 no-1300.

Ubukhulu be-ultrasound kwiiveki ezingama-27 ukuya kwe-28 zokukhulelwa

Ukuphuhliswa kwe-fetus ngeli xesha kuhambelana nenqaku eliqhelekileyo lophuhliso lomntwana ozalwe kwiiveki ezingama-28. Ubuninzi obukhulu obukunceda ukuqikelela ixesha lokukhulelwa:

• I-BDP (ubukhulu biparietal yekrele) 69.2 - 71.9 mm;
• I-LTE (ubukhulu be-frontotemporal yekrele) 88 - 91mm;
• DB (ubude besifazane) 50.9 - 52.9 mm;
• I-SDHK (ithetha ububanzi besifuba) 62.9 - 66.7 mm;
• I-SJ (ububanzi bentsholongwane yesisu) 71.3 - 75.4 mm;
• Ubungakanani be-placenta 30,6 - 31,3 mm.

Ubukhulu be-ultrasound kwiiveki ezingama-28 ukuya kwe-29 zokukhulelwa

Uphuhliso lwe-Fetal luhambelana nenqaku eliqhelekileyo lokuphuhliswa komntwana ozalwe ngeveki 28, ubukhulu obuphambili obunceda ukugqiba iminyaka yobudala:

• I-BDP (ubukhulu biparietal yekrele) 71.9 - 75.1 mm;
• I-LTE (ubukhulu beparietal ngobukhulu bekhayi) 91 - 94 mm;
• DB (ubude bethanga) 52.9 - 55.1 mm;
• SDHK (ububanzi bomyinge wesifuba) 66.7 - 69.0 mm;
• I-SJ (ububanzi bentsholongwane yesisu) 75.4 - 78.0 mm;
• Ubungakanani be-placenta 31.3 - 32.1 mm.

Kuzo zombini iimeko, i-placenta idla ngo-2 degrees of mature, ngaphandle kokungeniswa kwayo, ukuphakama kwe-amniotic fluid endaweni engahlawulelwayo kwiindawo ezingama-fetal akufanele kudlule i-70 mm. Zonke iigumbi ezi-4 zibonakala ngokucacileyo entliziyweni, ikhondo leenqanawa ezisemgangathweni lichanekile, isantya senhliziyo yesisu sisisigxina kwiveki yama-28 yesigxina, 130-160 ngomzuzu, intloko ikhona, amaqhosha ayengaphantsi kancinci, ukunyuka kwe-fetal kusebenza, ngokulinganayo, ukuya kwi-15 ngeyure.

Ukuphuhliswa kwentwaba kwiiveki ezingama-28 zesisu Umntwana ozelwe ngeli xesha unempawu zokungcoliswa kwangaphambili. Imiphunga yayo ayifumaneke ngokwaneleyo ngumbutho osebenzayo kwaye unokuvula kuphela. Ulusu lubomvu, lufakwe ngophezulu oluninzi ngaphandle kweethambo ezincinci, kwaye umntwana akakwazi ukuzimela ngokuzimeleyo ukulawula ubushushu bomzimba. I-membrane yamehlo inxalenye okanye ibuyiselwe ngokupheleleyo kwaye amehlo avulekile. I-Cartilages kwi-auricles ithambile. Amakhwenkwe angenawo amathande kwi-scrotum, amantombazana ayigubungeli imilomo emikhulu yelabi kunye nabancinci.

Kwiiveki ezilandelayo, umntwana kufuneka aqhubeke nokukhula kwisibeleko, kodwa nangalo xesha umntwana ozelweyo unethuba lokusinda, kodwa umama, ukuzalwa kungabungozi ngenxa yokuba kunokwenzeka ukuba ulungelelaniso lwangaphambi kwexesha, usebenze ngobunzima kunye nokulungelelaniswa kwenzalo yokuzalwa.
