Nangona kunjalo, ipharamitha ephambili esetyenziswe ukuxilonga imeko yesimo senhliziyo intlawulo yesimo senhliziyo (rate rate). Ngelo xesha, eli pharamitha litshintshile kwaye lixhomekeke ngokupheleleyo kwixesha apho ukuxilongwa kwenziwa khona.
Ziziphi iinkqubo zeHR kumaziko okuqala?
Ukucacisa ukungaphambuki, xa uhlalutya umsebenzi we-cardiovascular system yomntwana ongakazalwa, itheyibhile isetyenzisiwe apho umgangatho wentsholongwane yentliziyo isetyenziswe iiveki. Ingqwalasela ekhethekileyo ihlawulwa kwixesha apho ukuxilongwa kuqhutyelwa khona. Oku kuchazwa yinyaniso yokuba le parameter iyatshintsha ngokukhawuleza kangangokuba ekugqibeleni kwaye ekuqaleni kweveki enye imilinganiselo eyahlukeneyo inokumiselwa. Ngokomzekelo, ekuqaleni kweveki yesi-7, izinga lokushaya kwenhliziyo liyi-126 ibhokhwe ngomzuzu, kwaye ekugqibeleni ngu-149. Ngeveki ye-13 intlawulo yenhliziyo ingama-159 beats.
Inqanaba lentliziyo litshintsha njani kwi-2 kunye neyesithathu?
Intlawulo yenhliziyo, ishintshwe iiveki zokukhulelwa, ihlaziywa kwi-2 trimester. Ngoko ukususela kwiiveki ezili-12 ukuya kwezi-14 ukuya kwiziqhelo eziqhelekileyo ezithathwayo zi-140-160 ngeengcingo. Intliziyo enjalo ibonwa ngokukhawuleza kwenkqubo yokuzalwa. Ukuphambuka kule ndawo okanye kwicala elingaphambeneyo, ngokuqhelekileyo kubonisa ukuba kukho ukuphulwa. Ngexesha elifanayo, imbangela ebalulekileyo yokutshintsha kwexabiso lentliziyo kunoma yiliphi ixesha lokuxhamla li-fetus hypoxia. Ngokuqhelekileyo, kukhokelela ekunyuseni kwenani lentliziyo, i-tachycardia. Kwiimeko ezinzima ze-oksijini yendlala, i-bradycardia ivela, oku kuba ngumphumela wokuthi u-fetoplacental insufficiency. Kwiimeko ezinjalo, ugqirha ugqiba ukuba wenze ntoni ngokulandelayo: ukuba uzalwe ngaphambi kokuzalwa (ukuba kunokwenzeka kwaye uvumele ixesha) okanye ugcine umfazi, uzama ukuzinzisa imeko yakhe.
Inqanaba lentliziyo lihlolwa njani emva kwexesha?
Uvavanyo lwesantya senani lentliziyo, elenziwa iiveki zokukhulelwa, lwenziwa kamva ngoncedo lwe- CTG. Qalisa ngeeveki ezingama-32, kwaye phinda le nkqubo rhoqo kwiintsuku eziyi-14. Kanye kunye nokulungiswa kwentlawulo yenhliziyo, ukulungiswa kwezicatshulwa ze-uterine kunye nomsebenzi wemoto wengane. Zizo ezi zikhokelo eziqwalaselwe xa zivavanya imeko epheleleyo yomntwana, kunye nokuvavanya ukuphuhliswa kwe-intrauterine.
Yintoni eyenza utshintsho kwizinga lentliziyo yentliziyo?
Kukho izizathu ezininzi zokunyusa izinga lentliziyo yesisu. Le nyaniso inyanzelisa inkqubo yokuxilongwa, kwaye ngamanye amaxesha akunakwenzeka ukuseka okhokelela ekuphuhlisweni kwephulo. Nangona kunjalo, akusoloko kukho utshintsho kule nqondiso kubangelwa ukuphulwa okukhoyo. Ngoko, ukuphambuka kwentlawulo yenhliziyo ukusuka kwisiqhelo kungabangela:
- izifo ezingapheliyo ezikhulelweyo;
- Ukuphazamiseka kwesimo sengqondo sengqondo somfazi okhulelweyo;
- ukwandiswa komzimba.
Ukongeza kwimiba engentla, ukwanda kwenani lentliziyo kukhuthazwa ngumsebenzi ogqithiseleyo wemoto wesifazane okhulelweyo. Ngoko, ngovuko lo mbonakaliso lukhula kancinci, kwaye ngexesha lokuphumla intliziyo yomntwana ishaya kangangoko. Ezi zinto zikwaqwalaselwa kwakhona kwi-diagnostic.
Ngaloo ndlela, uphawu olunjalo lokusebenza kwenkqubo yesifo somntwana esiswini luyinto enolwazi kwaye isetyenziselwa ukuxilongwa kwezifo. Kwiimeko ezininzi, kungenxa yenguqu kule parameter oogqirha bamisela i-hypoalia ye-fetal, efuna ukulungiswa, ekubeni Kamva oku kuchaphazela kakubi ukukhula komntwana wesisu.
