Ngethuba lekota yokuqala , isantya senhliziyo yengane kufuneka iqale kwindawo ethile malunga ne-100 beats ngomzuzu (bpm) malunga neeveki ezingama-6 (ixesha lokubona okokuqala), ukuphakama kwiiveki ezingama-9 (ngamanye amaxesha ukuya kufinyelela kumanqanaba angama-180 bhontshi ngomzuzu) kwaye ngokukhawuleza kwehla njengoko umntwana esebenzisa ixesha.
I-ultrasound ibonakalise iNqanaba leNtsholongwane yeNtliziyo eLawulayo kwi-Trimester yokuqala. Ngaba Ndiza kuhlawula?
Xa isantya senhliziyo ihamba ngokukhawuleza kunokuba ilindeleke, ugqirha unokuphawula ukuba kukho isizathu esithile sokukhathazeka kwaye ucebise i-ultrasound yokulandelelana ukujonga ukukhula komntwana.
Inqanaba lentliziyo elincinci lisizathu sokuxhalabisa kuba uphando lubonisa ukuphakama okuphezulu xa umntwana enesantya senhliziyo esingaphantsi kwama-100 ngeengqungquthela ngehora kwi-6.2 iiveki zokukhulelwa okanye ngaphantsi kwama-beats angama-120 ngomzuzu kuma-6.3 ukuya kwiiveki ezi-7.
Ukuba i-ultrasound yakho ibonisa ukuba umntwana wakho wayenomlinganiselo osantya kwintliziyo, mhlawumbi uyothuswa kwaye uxhalabele, ingakumbi ukuba ufuna ukufumana ulwazi malunga nokuba lithetha ntoni oku. Unokuvakalelwa kukuba kufuneka ulinde iiveki ukulandelelana. Kodwa ngelishwa, akukho ndlela yokuxelela oko kwenzeka ngaphandle kokulinda. Ngamanye amaxesha isantya senhliziyo yengane iya kulungelelanisa, kwaye ukukhulelwa kuya kuqhubeka ngaphandle kweengxaki. Kodwa ngokudabukisayo maxa wambi isiphumo sihamba ngenye indlela. Akukho nto wena okanye ugqirha wakho onokukwenza ukuchaphazela umphumo wokugqibela. Xa ukukhulelwa kuthinteka emva kokubona isantya senhliziyo esancinci, isisombululo sihlala sisisifo esingaqhelekanga esasikhona ekukhulelwe.
Ixabiso le-ultrasound ngexesha lokukhulelwa
Ngexesha lokukhulelwa, i-ultrasound isetyenziselwa izizathu ezininzi kubandakanya oku kulandelayo:
- Ukuthandana (ukuqikelela iminyaka yobudala bomntwana)
- Ukuhlolwa kwe-Aneuploidy (chromosome)
- Uvavanyo lobude besibeletho
- Ukumiselwa kwenhlalakahle yobumntwana ( iphrofayili ye-biophysical )
- Uhlolo lwe-Anatomical
Ngexesha leveki ezili-13 ukuya kwezi-18 zokubeleka, ubudala bomntwana buyakunqunywa ngokusebenzisa i-ultrasound.
Imilinganiselo eyahlukeneyo isetyenziselwa ukuqikelela ubuncinane bomntwana kuquka oku kulandelayo:
- Ububanzi beBiparietal
- Isihloko seNtloko
- Isibilini sesisu
- Ubude be-Femur
Ukuchaneka kokuthandana kubandakanya okanye kuthatha iintsuku ezi-7. Ngamanye amazwi, ubudala bomntwana buqikelelwa ngaphakathi malunga neveki. Kwiiveki ezingama-24, oluchanekileyo linciphisa kwaye i-ultrasound isetyenziswe kakuhle ukuvavanya ubunzima bomntwana kunye nokukhula.
Ukusebenzisa i-ultrasound, iitoni zenhliziyo zomntwana zithethwa kwiiveki ezili-10. Kuthatha iiveki ezi-18 ukuya kwe-20 ukuva intliziyo yesana usebenzisa i-fetoscope.
I-ultrasound yimiqathango yegolide, okanye indlela engcono, ukujonga ukuba umntwana uyaphila. Ngokudabukisayo, ukuba umntwana ukhona kodwa akukho ntliziyo ifunyenwe, ngoko umntwana ufile.
I-Heartbeat engcolileyo iboniswe ngexesha le-Ultrasound
Ngamanye amaxesha ngekota yokuqala yokukhulelwa, akucaci ukuba kukho intliziyo. Kule meko, iimvavanyo ezongezelelweyo kufuneka zenziwe ukuba zibone ukuba umntwana usaphila. Ezi mvavanyo zibandakanya amanqanaba e-serial beta hCG, uhlobo lwe-hormone yokukhulelwa.
Ukukhulelwa komntwana ngexesha lokukhulelwa kwangaphambili
Ngethuba lokukhulelwa kokugqibela, uphawu lokuqala lokuphelelwa ngumntwana ngokuqhelekileyo ludinga ukuhamba. Xa umntwana engashukumi, i-ultrasound ingasetyenziselwa ukufumana intliziyo yesisu kunye nokufumanisa isizathu sokungabikho kokuhamba komntwana.
