Dopplerometry kwa amayi apakati - zizindikiro, kawirikawiri

Fetal dopplerometry ndi mtundu wapadera wa ultrasound, momwe kuyendera kwa makhalidwe ndi maonekedwe a magazi mu zotengera za chiberekero, placenta ndi fetus zimachitika. Ndi phunziro ili lomwe limatithandiza kudziwa nthawi yotsutsana, monga, fetal hypoxia.

Ndi zizindikiro ziti zomwe zimaganiziridwa mu dopplerometry?

Pogwiritsa ntchito dopplerometry, oyenerera amayi apakati, amayi ambiri amasangalatsidwa ndi zizindikiro za chikhalidwe. Popanda kuyembekezera chigamulo cha dokotala, amayi amtsogolo amayesa kupeza zotsatira za kufufuza okha. Musati muchite izi, chifukwa pofufuza yankho, pali zinthu zambiri zomwe muyenera kuziganizira.

Kuwona magazi akuyenda pa dopplerometry mwa amayi apakati muziganizira zizindikiro zotsatirazi:

• Nthendayi (IR) - ndi kusiyana pakati pa systolic (panthawi ya kupanikizika kwa mtima) ndi ma diastolic (kumasuka) kuchuluka kwa magazi;
• pulse index (PI) - chiŵerengero cha kusiyana pakati pa systolic ndi diastolic kuthamanga ku mtima wa mtima wa liwiro la chotengera chopezeka;
• systolic-diastolic chiŵerengero (SDO) - chiŵerengero cha magazi chikuyenda mofulumira kudzera m'zombo kupita ku gawo la systole ndi diastole.

Kodi kuyesa kwa zotsatira za dopplerometry ndi motani?

Zizindikiro zapamwamba zomwe zili pamwambazi za amayi apakati zimayesedwa mosiyana. Pachifukwa ichi, matenda a mitsempha amachitidwa mosiyana ndipo magazi amatha kuyenda m'mimba ya uterine, umbilical, carotid ndi ubongo, komanso aorta.

Chizoloŵezi cha zizindikiro za dopplerometry kwa amayi apakati zimasintha nthawi zonse, ndipo chimadalira nthawi ya mimba.

Kotero, SDO mu mitsempha ya uterine, kuyambira pa sabata la 20 kufikira nthawi yoberekera, ndi 2.0.

LAD, ndipo ndi PI, IR mu mitsempha ya umbilical chingwe imachepetsanso pang'onopang'ono m'kati mwa 2 ndi theka la mimba.

SDO ya masabata amasintha motere:

• Sabata 20-23 - 0,61-0,80;
• 24-29 sabata - 0.57-0.77;
• Sabata 30-33 - 0.519-0.74;
• Sabata 34-37 - 0,49-0,7;
• Masabata 38-41 ndi 0.40-0.68.

Mndandandanda wazomwe umakhala nawo, umasinthidwanso pa nthawi yogonana:

• Sabata 20-23 - 3.8-3.95;
• 24-29 sabata - 3,3-3,5;
• Sabata 30-33 - 2,5-2,8;
• Sabata 34-37 - 2.4-2.6;
• Masabata 38-41 - 2,18-2,22.

Komabe, mayi aliyense wamtsogolo ayenera kumvetsetsa kuti zizindikiro zomwe wapatsidwa zimagwiritsidwa ntchito mogwirizana ndi zomwe zimachitika pa mimba. Choncho, palibe chifukwa choyenera kudziwa zomwe zimapezeka chifukwa cha doplerometry .
