Ukuzalwa kobomi obutsha kuyimfihlelo enkulu. Namhlanje, oogqirha banezixhobo zabo ezivumela ukuba "bajonge" kwihlabathi langaphakathi, kodwa ke asikazazi zonke iziqhelo zokuphuhliswa komntu ozayo, kodwa sinokugweba isimo somntwana, ngokuyisiseko, kuphela ngentlawulo yenhliziyo (izinga lentliziyo). Oomama abanomdla abanexhala kunye nexhala bayaziphulaphula, benentliziyo edibeneyo, balindela iziphumo ze-ultrasound okanye i-CTG - konke okulungileyo kunye ne-crumb? Iiprotoksi zophando, njengomgaqo, ziqulethe ixabiso elihlukileyo: intliziyo yomntwana ihlala iguqukela, ngoko ke imigangatho yesantya senhliziyo yesisu iyahluka kakhulu ngeveki.
Inqanaba lentliziyo yentliziyo kwi-trimester yokuqala
Intliziyo yesibindi isakhiwe kwiiveki ezi-4-5 zokukhulelwa. Kwaye sele sele ngeveki yesi-6, intliziyo ye-fetal "iyava" kunye nenzwa ye-ultrasound sensation. Ngeli thuba, intliziyo kunye nenkqubo yesantya yomntwana ayisayi kudala, ngoko kwinqanaba lokuqala kukho imilinganiselo yentliziyo yefestile kwiiveki , ukuvumela ugqirha ukuba alandele ukuphuhliswa kunye nemeko yengane. Ixabiso le-fetal heart rate ngeveki linikezelwa kwithebula elilandelayo:
| Ixesha lokukhulelwa, iiveki. | Inqanaba lentliziyo, ud./min. |
|---|---|
| 5 (ukuqala komsebenzi wentliziyo) | 80-85 |
| 6 | 103-126 |
| Wesi-7 | 126-149 |
| 8 | 149-172 |
| 9 | 175 (155-195) |
| 10 | 170 (161-179) |
| 11 | 165 (153-177) |
| 12 | 162 (150-174) |
| 13 | 159 (147-171) |
| 14 | 157 (146-168) |
Nceda uqaphele ukuba ukusuka kwi-5 ukuya kweveki ye-8 kubandakanyeka, amazinga akwa-HR kubantwana ekuqaleni nasekupheleni kweveki (ukwanda kwenani lentliziyo) kunikwa, kwaye ukususela kwiveki ye-9 yokukhulelwa izinga lokunyamekela kwenhliziyo kunye nokunyamezela kwabo kunikwa. Ngokomzekelo, intliziyo ye-fetal ibetha kwiiveki ezi-7 iya kuba yi-126 ibhokhwe ngomzuzu ekuqaleni kweveki kunye ne-149 beats ngomzuzu ekupheleni. Kwaye kwiiveki ezingama-13 umlinganiselo wentliziyo yesisu, ngokuqhelekileyo, kufuneka ibe yi-159 beats ngomzuzu, ixabiso eliqhelekileyo liya kuqwalaselwa ukusuka kwi-147 ukuya kwi-171 ibhokhwe ngomzuzu.
Inqanaba lentliziyo ye-Fetal kwisiqingatha sesibini nesithathu
Kukholelwa ukuba ukusuka kwiiveki ezi-12 ukuya ku-14 zokukhulelwa aze abelethe intliziyo yomntwana kufuneka ngokuqhelekileyo enze iinqwelo eziyi-140-160 ngomzuzu. Oku kuthetha ukuba izinga lentliziyo ye-fetal kwiiveki ezili-17, iiveki ezingama-22, ezingama-30 kunye neeyure ezingama-40 kufuneka zihlale zifana noko. Ukwehlukana kwelinye icala okanye kwelinye kubonisa ukungonwabi komntwana. Ngokukhawuleza (i-tachycardia) okanye i-bradycardia, i-bradycardia, inokuqala, iya kukhankanya i-hypoxia ye-intrauterine ye-fetus. I-Tachycardia ibonisa i-oxygen elambileyo yenkwenkwe yentsana, ebonakala ngathi ngumphumela wokuhlala ixesha elide lomama kwigumbi elincinci okanye ngaphandle kokunyakaza. I-Bradycardia ithetha nge-hypoxia enobuhlungu, ngenxa yokungafezeki kwe-fetoplacental. Kule meko, unyango olunzulu, kwaye ngamanye amaxesha ukuhanjiswa kwexesha eliphuthumayo kunye necesarean section (ukuba unyango lwexesha elide alisebenzanga kwaye isimo se-fetus siqhubeka sihlahloka) kuyimfuneko.
Kwiiveki ezingama-32 kunye nesantya senhliziyo yentliziyo kamva kunokunqunywa ukusebenzisa i-cardiotocography (CTG). Ngokuhambisana nomsebenzi wentliziyo womntwana, i-CTG ibhalisa iziphene zesisu nomsebenzi womntwana. Ukukhulelwa kokukhawuleza
Kukho ezinye izimbangela zokuphula umthetho wesisu sentliziyo: ukugula kowesifazane okhulelweyo, ukukhathazeka kwakhe ngokomzwelo okanye ukukhathazeka, ukwenziwa komzimba (umzekelo, i-gymnastics okanye ukuhamba). Ukongezelela, izinga lentliziyo lomntwana lixhomekeke kwimisebenzi yakhe yemoto: ngamaxesha okuvuka kunye nokunyakaza, intliziyo yesanda iyanda, kwaye ngexesha lokulala intliziyo encinci iyabulala rhoqo. Ezi zinto kufuneka ziqwalaselwe ekuhloleni umsebenzi womzimba womntwana.
