Naliphi na umama uya kukhumbula ngonaphakade izandi zentliziyo yengane yakho, evela kwi-device e-ultrasound. Kusukela kulo mzuzwana ukuba owesifazane okhulelweyo uyaqala ukuphulaphula umzimba wakhe, ezama ukubamba ama-echoes of life ngaphakathi kwakhe.
Isixhobo sokuhlola intliziyo yesifo
Kukho iindlela ezininzi zokubeka esweni ukubonakala kunye nokuvakala kwemivimbo yesifo senhliziyo. Umshini oqhelekileyo we-ultrasound ungabamba intliziyo yesisu kwisonto le-6, xa lifikelela kuma-130 ukusika ngomzuzu. I-phonendoscope yonyango eqhelekileyo yenza ukuba kube lula ukubala le data kuphela kwiiveki ezingama-16, xa isingqimba saso siba soloko siba ngaphezu kowesifazane okhulelweyo. Izandi ezivalelekileyo zokubetha kwentliziyo ngumbono wezifo zengqondo zesazi kunye nezobuchopho ziza kubamba, zibambe indlebe kwisisu somfazi. Kwakhona, isixhobo sisetyenziswa ngokubanzi nge-echocardiograph, esikuvumela ukuba uhlalutye imeko jikelele yeemithwalo yegazi kunye nentliziyo, kunye nokuphanda ukunyuka kwegazi kumanzi onke. Ukuvavanya intliziyo yesisu ngaphambi kokuzalwa kwesigqirha kunceda i-cardiotocograph. Nguye obonisa imeko yokwenene yomzimba womntwana kunye nesingqimba sokuqhawulwa kwezihlunu ze-uterine. Inika izibonakaliso zangempela zokuzaliswa kwintsana ne-oxygen kunye nomsebenzi wayo kwinkqubo yabasebenzi.
Inqanaba lentliziyo ye-Fetal ngeveki
Kwizonyango, kukho imilinganiselo ethile yentlawulo yentliziyo yesibhozo kwiiveki, nayiphi na ukuphambuka okumele kubangele ukuba uqaphele umama nodokotela ombona. Nazi ezinye izibalo eziqhelekileyo:
- Isantya senhliziyo yentlungu kwiiveki ezi-7 kufuneka ngokuqhelekileyo ibe malunga ne-110-130 ibhokhwe ngomzuzu;
- intliziyo ye-fetal kwiiveki ezi-13 kwaye de kube sekupheleni kwenkqubo yokuthoma i-140-160 ibetha ngomzuzu.
Uvavanyo lokukhulelwa okucwangcisiweyo luya kubonisa intliziyo yesisu kwiintsuku ezingama-19. Ukunxibelelana kwesiqhelo kwiimimiselo kuya kunceda ukukhupha konke ukwesaba nokwesaba. Umntwana sele sele ehamba ngokunyanisekileyo, uchitha i-oksijeni engaphezulu, ngokulandelanayo, kunye nentliziyo yokubetha iphindaphindiweyo. Ekubeni kukho nasiphi na isifo sokukhulelwa, unokufuneka ulandele intliziyo ye-fetal kwiiveki ezingama-20 kunye nayo yonke into elandelayo, ukuze uphelise umngcipheko wokufa kwangaphakathi kwintsana.
Ukubethelwa kwe-fetus kwiiveki ezingama-23 sele sele kuluhluke kakhulu kangangokuba kuvumela ugqirha wokumamela ukuphulaphula imisindo engaphandle kunye nokuvavanya iitoni zesisu senhliziyo. Le nqubo ibizwa ngokuba yi-auscultation. Ukufunyanwa kweentliziyo ezingenangqondo, ezingenakunyaka okanye ezingavumelekiyo zingabonakalisa intsana yomoya we-oksijini yindlala.
Ngesigqibo esifike ngexesha sokubhalisa kwintetho yomfazi, umfazi okhulelweyo uthunyelwa kwesinye isiqhelo se-ultrasound, esenza isigxina se-fetal ngesonto 30, imeko yayo jikelele, isikhundla, njl. Kulo xesha ukuba kusetyenziswe i-echocardigraph kunye nokuchonga indawo ekhoyo yenhliziyo kwintsana yengane inokwenzeka.
Ukuba unina uneengxaki ezinkulu zempilo kunye nokuphambuka ekuphuhlisweni komntwana, kubalulekile ukurekhoda izinga lentliziyo ye-fetal ngeveki 32, eyenziwa ngokusebenzisa indlela ye-cardiotocography. Ngeyure ukuphindaphindwa kwemivalo yesifo senhliziyo yomntwana kubhaliweyo kunye nokuhluka kwayo ngexesha lokulwa.
Kwiiveki zokugqibela zokubeleka umntwana usele mkhulu kwaye uhlala kwindawo yonke kwisibeleko. Ukusebenza kwemoto kunciphisa, kubonakala kubuthelela amandla afunekayo ekuzalweni. I-ultrasound ye-fetal heartbeat kwiiveki ezingama-38 iya kubonisa ukuncipha kwexesha eliphindaphindiweyo kwinqanaba lokuqhekeza, okuqhelekileyo kweli nqanaba.
Ekupheleni kokukhulelwa, isibeleko sisetus, esinokuchaphazela kakubi ukunikezelwa kwe-oksijini kumntwana. Akunangqiqo ukuphanda izinga lentliziyo ye-fetal ngeveki 39, njengoko ukuzalwa kusondele kakhulu kwaye ukuvavanya kwimeko yayo kuya kuba nolwazi oluxabisekileyo kumgqithisi.
Gcina intliziyo yeeveki kuphela kubafazi abanomlinganiselo othile wokungaphazamiseka kwesigxina.
