Ndezvipi zviratidzo zvinotorwa mu dopplerometry?
Paanosarudza dopplerometry, yakatemerwa vakadzi vane pamuviri, vakadzi vakawanda vanofarira zviratidzo zvemaitiro. Pasina kumirira kuguma kwechiremba, vanaamai vekupedzisira vanoedza kuona chigumisiro chekutsvakurudza ivo pachavo. Usaita izvi, nokuti paunenge uchiongorora mhinduro, zvinhu zvakawanda zvinofanira kuverengwa.
Kuongorora ropa rinopera panguva yedopplerometry muvakadzi vane pamuviri vanofungisisa zvirevo zvinotevera:
- Resistive index (IR) - ndiwo musiyano pakati pe systolic (panguva yekuputika kwemoyo) uye diastolic (kuruvara) mahara ekuyerera kweropa;
- pulse index (PI) - chiyero chepakati pakati pe systolic uye diastolic velocity kusvika kuhupenyu hwechimiro chekurumidza kwechikepe chakaonekwa;
- systolic-diastolic ratio (SDO) - chiyero chekuyerera kweropa kupfurikidza nemidziyo kusvika muchikamu che systole uye diastole.
Iko kuongororwa kwemigumisiro ye dopplerometry?
Chimwe chezvinhu zvakataurwa pamusoro apa dopplerometry zviratidzo zvevakadzi vane pamuviri vanoongororwa zvakasiyana. Muchiitiko ichi, kuongororwa kwemasayeri kunoshandiswa kushandiswa uye ropa richiyerera mu uterine, umbilical, carotid uye cerebral arteries, uyewo mu aorta, inotorwa.
Chimiro chezviratidzo zve dopplerometry kuvakadzi vane pamuviri zvinogara zvichichinja, uye zvinoenderana nenguva yekuzvitakura.
Nokudaro, i-SDO muhutachiona hwehutachiona, kubva pamusi we20 wevhiki kusvika panguva yekuzvarwa, i 2.0.
KANA, uye neyo PI, IR mune mitsetse ye umbilical cord inoderera zvishoma nezvishoma uye zvishoma nezvishoma mukati me2 nehafu yepamuviri.
I-SDO yevhiki ichishandura sezvinotevera:
- 20-23 vhiki - 0,61-0,80;
- 24-29 vhiki - 0.57-0.77;
- 30-33 vhiki - 0.519-0.74;
- 34-37 vhiki - 0,49-0,7;
- I 38-41 vhiki iine 0.40-0.68.
Nhamba yekusunungura, zvakare, inoshandura panguva yekugumira:
- 20-23 vhiki - 3.8-3.95;
- 24-29 vhiki - 3.3-35;
- 30-33 vhiki - 2,5-2,8;
- 34-37 vhiki - 2.4-2.6;
- 38-41 vhiki - 2.18-2,22.
Zvisinei, amai vese vemangwana vanofanira kunzwisisa kuti zviratidzo zvakapiwa zvinotorwa munyaya pamwe chete nezvinoitwa panguva yekudzivirira. Nokudaro, pasina chikonzero chinofanira kunge zvakakosha kududzira tsika dzakagadzirwa sechikonzero che doplerometry pachako .
