I-Ultrasound kwiiveki ezingama-32

I-ultrasound ifakiwe kwisicwangciso esisezantsi sesifundo ngexesha lokukhulelwa. I-ultrasound icwangcisiwe kwaye ayiyihlongozwayo, icebo eliye lacwangciswa linemihla ecacileyo kwaye ihlolisisa ukufumanisa ukungasebenzi komntwana kunye nokugula kwemfuyo. I-ultrasound yokuqala iqhutywe kwiiveki ezingama-9-11, okwesibini ngo-19-23, kwaye i-ultrasound yokugqibela ekukhulelweni iyenziwa kwiiveki ezingama-32-34.

Kutheni uqhuba i-ultrasound trimester yokukhulelwa?

Inye yesithathu ehleliweyo ngexesha lokukhulelwa lenzelwa ezi zinto zilandelayo:

• ukuvavanya urhulumente wendawo osebenzayo kunye nomsebenzi we-placenta (ukuchithwa kokungenakuthola kwe-placental);
• ngenjongo yenkcazo yesimo somzimba wesisu (ukukhuphela ukulibaziseka kokuphuhliswa kwe-intrauterine) kunye nendawo yayo kwindawo yesisu (intloko, i-pelvic, isiphambano);
• ukwenza i-biometrics yobusana (ukulinganisa umda wekhanda, umlenze kunye nesisu), misela ukuhambelana nobukhulu bomntwana kwisithuba sokukhulelwa.

Ingane ibukeka njani i-ultrasound kwisithathu sesithathu sokukhulelwa?

Kwi-ultrasound ye-fetus yeeveki ezingama-30, kunokubonwa ukuba ulusu alusekho wrinkled, kodwa lugqibelele. Ubunzima bomntwana ngu-1400 grams, kwaye ubude buyi-40 cm.

Ngethuba le-ultrasound kwiiveki ezingama-32 zesisu, unokubona ukuba ubunzima bomntwana buyi-1900 gram, kwaye ubude buyi-42 cm. Umntwana sele ufana nomntu omncinci, unayo yonke into esebenziweyo, ngexesha le-ultrasound uyakwazi ukubona ukunyakaza kwakhe (isantya, ukuxhoma ngeengxaki kunye nemilenze). Xa uqhuba i-ultrasound kwi-3D kunye ne-4D, unokubona amehlo omntwana.

Ukuvavanya kwe-biometry ebusweni kwiiveki ezingama-32:

• ubungakanani biparietal ngeli xesha lilingana no-75-89 mm;
• usayizi wes occipital ubungakanani nge ultrasound ngu-95-113 mm;
• i-circumference yentloko ye-fetal ngokuqhelekileyo i-283-325 mm;
• umjikelezo wesisu somntwana kwiveki ye-32 ngowama-258-314 mm.

Xa ulinganisa amathambo ende, iziphumo ezilandelayo zifumaneka ngokuqhelekileyo:

• ubude bebhinqa ngu-56-66 cm;
• ubude be-humerus - 52-62 cm;
• ubude bamathambo obushushu buyi-45-53 cm;
• ubude bamathambo ama-shin buyi-52-60 cm.

Nge-ultrasound kwiiveki ezingama-33 zokukhulelwa, unokubona ukuba ubunzima bomntwana bunyuke ngo-100 grams kwaye sele sele bu-2 kg, kwaye ukukhula bekuyi-44 cm.

Ngombulelo kwi-ultrasound, uyabona ukuba ekuqaleni kwekota yesithathu yokukhulelwa, umntwana usuqalile ngokupheleleyo kwaye ezinyangeni zilandelayo ziza kukhula ngokukhawuleza kwaye zibe namandla. Ngoko ke, kwi-trimester yesithathu, kubaluleke kakhulu ukuba umama ozayo kufuneka adle ngokulinganayo kwaye angasebenzisi kakubi umgubo kunye nocoko.

Ukukhupha i-ultrasound yesithathu ekukhuleleni kubandakanya ukuqhuba i-doppler, ukwenzela ukuvavanya ukuhamba kwegazi kwimida ye-strings. Ngaphambi kokungaqhelekanga, kuyadingeka ukuba kwenziwe i-doplerometry yeempahla ezisele (intsimbi ye-cerebral, i-uterine arteries, i-aorta ye-fetus).

I-ultrasound ekukhulelweni kwexesha elide

I-ultrasound emva kweveki ezingama-34 ayilungiswanga kwaye iyenziwa ngokwalathiso. Ukuba umfazi waqala ukuphazamisa ukukhuphaza komntwana, kunye ne-lethargic okanye okanye wayeka ukuva. Esinye isibonakaliso se-ultrasound ekukhulelweni kokukhawuleza kubakho ukuphuma kwegazi ngokuthe ngqo kwi-genital tract (ngegazi elinzima, lo mfazi uboniswa ngokukhawuleza kwinqanaba le-caesarean). Kwi-ultrasound, ungabona ubungakanani be-hematoma kunye nokwanda kwayo okunokwenzeka. Uzi kwiiveki ezingama-40 zesiganeko kwaye emva koko waqhutyelwa ukuxilonga intambo kunye nokuxinisa intambo.

Njengoko sibona, i-ultrasound kwi-iveki ye-32 yokukhulelwa ibaluleke kakhulu ekufundeni ukuxilonga okuvumela ukuxilonga i-pathology ye-placenta ngexesha, kunye nokuvavanya ukuphuhliswa kwe-fetus (usebenzisa i-biometrics) nokuthotyelwa kwayo ngexesha lokunyuka. Kwi-ultrasound kwi-3rd trimester, kunyanzelekile ukuba wenze i-artery doppler.
