I-Dopplerometry yabasetyhini abakhulelweyo - izikhombisi, eziqhelekileyo

I-dopplerometry ye-fetal yinto ekhethekileyo ye-ultrasound, apho uvavanyo lweempawu kunye neempawu zokuhamba kwegazi kwiinqanawa zesisu, i-placenta kunye ne-fetus zenziwa. Le sifundo esivumela ukuba sikwazi ukuchonga ngexesha elifanelekileyo ukuphulwa, njengokuba, umzekelo, i- hypoalia yesisu.

Ziziphi iinkcazo ezibhekiselwe kwi-dopplerometry?

Xa kulungiswa i-dopplerometry, emiselweyo kwabasetyhini abakhulelweyo, abaninzi abafazi banomdla kwizikhombisi zesimiso. Ngaphandle kokulindela isigqibo sogqirha, oomama bokamva bayazama ukufumana umphumo wophando ngokwabo. Musa ukwenza oku, kuba xa uhlalutya impendulo, ezininzi izinto kufuneka ziqwalaselwe.

Ukuvavanya ukuhamba kwegazi ngexesha le-dopplerometry kubafazi abakhulelweyo baqwalasele ezi zilandelayo:

• Inkcazo yokuxhaswa (IR) - ngumlinganiselo phakathi kwe-systolic (ngexesha lokuqhaqha kwentliziyo) kunye ne-diastolic (ukuphumla) amazinga okuhamba kwegazi;
• I-index index (PI) - umlinganiselo wokohluko phakathi kwe-systolic kunye ne-diastolic velocity kwixabiso lentliziyo yesantya sesitya esifumene;
• Umlinganiselo we-systolic-diastolic (SDO) - umlinganiselo wokujikeleza kwegazi ukuhamba ngeempahla ukuya kwisigaba se-systole kunye ne-diastole.

Njani ukuhlolwa kweziphumo ze-dopplerometry?

Izicatshulwa zezidumbu ze-dopplerometry zilapha ngasentla zihlolwe ngokwahlukileyo. Kule meko, ukuxilongwa kwemibhobho yenziwa ngokuthe ngqo kwaye ukuphuma kwegazi kwi-uterine, umbilical, i-carotid kunye ne-cerebral arteries, kunye ne-aorta, ithathwa ingqalelo.

Isiqhelo sezibonakaliso ze-dopplerometry kubasetyhini abakhulelweyo bahlala beshintsha, kwaye kuxhomekeka kwithuba lokukhulelwa.

Ngaloo ndlela, i-SDO kwimibhobho ye-uterine, ukususela kwiiveki ezingama-20 kude kube ngumzuzu wokuzalwa, ngu-2.0.

I-LAD, kwaye kunye nayo i-PI, IR kwimibhobho yomtya we-umbilical iyancipha ngokukhawuleza kwaye kancane kancane kwi-2 nesiqingatha sokukhulelwa.

I-SDO yeenguqu zenguqu ilandelayo:

• 20-23 iveki - 0,61-0,80;
• 24-29 iveki - 0.57-0.77;
• 30-33 iveki - 0.519-0.74;
• 34-37 iveki - 0,49-0,7;
• Iveki yama-38-41 i-0.40-0.68.

Isalathisi sokusasaza, kwakhona, sitshintshana ngexesha lobunzima:

• 20-23 iveki - 3.8-3.95;
• 24-29 iveki - 3,3-3,5;
• 30-33 iveki - 2,5-2,8;
• 34-37 iveki - 2.4-2.6;
• Iveki ye-38-41 - 2.18-2,22.

Nangona kunjalo, wonke umama ozayo kufuneka aqonde ukuba izikhombisi ezinikeziwe ziqwalaselwa ngokubambisana neendlela zokukhulelwa. Ngoko ke, akukho mfuneko ukuba kuyimfuneko ukucacisa iimpawu ezifunyenweyo ngenxa ye- doplerometry ngokuzimeleyo .
