Doppler fetal: hana a me ka ho omńkalakala

I kēia mau lā i loko o kaʻike, o fetal malformations a me ka maʻamau pele o ka hāpai keiki kāna hana i increasingly hoʻohana laekahi lako a pan e leie aku, e nānā i ka pilikia, mai o ka loko. Kani ultrasonic i hoʻomākaukauʻia mea i lohe nui ia i loko o kaʻike, a me ka Ikepili o ka maʻi a me na kumu o ke kanaka kino. Oia haʻawina i paa i loko o 'inikua me ka hana pono, aʻaneʻane nō paʻa mau i loko o ke kaʻina hana o ka kilo lapaau, a. No ka hapai nā wāhine, ma ka hou ana i ka pololei, haʻawina hoonoho fetal ultrasound me ka Doppler velocimetry. He hana maʻamau no kekahi 'inikua waena.

Doppler

Ma ka holoʻokoʻa wā o ka gestation bebe wahine i kauoha mai ai study ultrasound mīkini. Ma kekahi mau kahua o ka hoʻonaʻauao o ka hāpai keiki, fetal Doppler ua ia no ka noiʻi a me ka Kāohiʻana o developmental kāna hana. Doppler - ultrasound o kekahi o ka laha ', a ua ana hanaʻia i loko o ka mahina hope o ka hāpai keiki, i hookuu i ke kolu o ka trimester.

Study o ke koko i loko o ka kikowaena arteries fetus, ka uterus, ke keiki e loiloi i ke koko kahe māmā holo a me ka moku'āina o na moku nui, a umbilical arteries, hoomaopopo ana i ke kākoʻo a me ka kino fetus. E lawe mai ia i ka ao pono he kupaianaha kīʻamo. Nō kāu, Doppler ultrasound ua hana pū me ka nui a me ka hiki ke lawelawe me ke kaawale, hou study kauka.

Ka hoʻokohu 'ana ultrasound me ka Doppler

Doppler e hooholo i ka kiko'ī nui, i ke anawaena a me ka wahi o ka papa kuhikuhiE arteries,ʻaʻole wale nō i ka hua, akā, i ke keiki, ka piko, he wahine ka uterus, i ke koko māmā holo i loko o nā kīʻaha, a me kekahi mea e hiki i ka 'eleu ka loaʻaʻana o ke alo aku o kekahi paewaewa ole ia'na hana o ke keiki, a hiki e he harbinger o likeʻole complications nā i hāpai keiki, a ma ka hana. No laila, o ka nui o ka noiʻi e ole e underestimated. Penei, 'eleu Doppler fetal transcript o kona kiko'î ae manawa e lawe mai kāohi hoomau, hooluolu aku au i ke ano a me kaʻole hiki ka pilikia.

Nāʻikepili no ka Doppler

Doppler like hou noiʻi ua koi 'ia e koho, inā i loaʻa ka wahine hapai i ke kēia mau maʻi:

• Preeclampsia.
• Hypertensive naʻau maʻi.
• Hakuʻala maʻi.
• Mimikō mellitus.

No hoi Doppler fetus hiki o ka lanakila ma ka kakahiaka nui ka loaʻaʻana o developmental kāna hana, congenital mā, developmental lohi, oligohydramnios, manawa kūpono o premature maturation o ke keiki, ka piko abnormalities i loko o ka 'ole paha congenital chromosomal abnormalities, loa ano o ka naʻau maʻi, a no laila, ma luna o.

I ka like o ka uterine artery Doppler iaoia

Doppler like o ka uterine artery e loiloi i ka moku'āina o ka vascular'ōnaehana o ka uterus, keiki, mezhresnichnogo ka lewa. Ho okumu mezhresnichnogo makahiki ia lŘlŘ a hiki i ka embryo implantation, ka hola hoʻokahi pule ma hope o hapai ana. Koko holo i loko o ka uterus o na wahine, e i i ke komo o nā arteries: ovarian a me ka uterine. A hiki i ka ho okumu ana o ke keiki i loko o nā paia o nā arteries, kekahi loli ana, i a laila e alakai ai i ko lakou ulu, a? Anoe? I ia laua me ka ulu ana o ke keiki. Ma keia kaʻina, uteroplacental koko ua hanaʻia e ke hoʻokō 'ho okumu ana o ke keiki, a māhuahua 10 manawa.

Uterine artery Doppler e leie aku e loiloi i ka functioning o kaʻoni iho artery kahua i terminates i ka luna o ka 3rd trimester. Inā complications ai ka haohao ana iloko o hāpai keiki, aole ia e ana i loko o nā arteries a pau o physiological loli, no laila, ka mea e ole hoʻonui a ulu i ka ulu ana o ke keiki. Hiki arteries e hikiʻole e hōʻoia 'ai a māʻona holo a me ke koko kahe ana i ke keiki, a e alakai i ka make ana o ka mea, a me deficiency o ka mahuaola, ka oxygen. Kēia, ma ka huli, e alakai i ka placental abruption, miscarriage a me ka miscarriage.

Doppler: transcript

Iloko o ka Doppler study ma ultrasound mea pale i kekahi mea kiʻi e hoohalike ai i ke koko velocities o na arteries i kēlā cardiac kalapona, a oko ma ka systolic a me ka diastolic. E maopopo i loko o ka wā e hiki mai, ka mea ma ua lü, hana transcript:

• Systole - ka manaʻo koikoi mai ana ka ka ho'ēmiʻana o ka naʻau Muscle.
• Diastole - o ka'aloʻahiʻa ua loaʻa i hoʻomaha o ka naau Muscle.

No laila, no ka mea, hookahi o lakou naau lanakilaʻikepili hōʻike ma systolic a diastolic ke koko, i loko o nā arteries. No kela a me keia o na moku hoao ana i kona mau rula a me nā 'ano typical koko māmā holo curves.

E loiloi i nā puke maʻamau, a me nā hoailona o ke koko hoʻohana i nā kēia indices:

• Systolic-diastolic lākiō.
• Lāʻau ikiʻai wale inideka.
• ia'ku inideka.

Systolic-diastolic lākiō, i ka lāʻau ikiʻai wale inideka a me ka ia'ku inideka noonoo i ka moku'āina o ka papa kuhikuhiE arteries a me ka aorta a me ke koko pele i loko o ia mau mea, i mea i ka manaʻo o kēia ao, e like me ka Doppler. Kūmau a me nā deviations mai o ia noonooʻano o ka 'aʻe' ana o fetal? Acaeoey, hoakaka i ka pathology pili i ke kanawai o ke koko ma luna o ke keiki hanau ana. No laila, i ke kauka ke Loiloi i ka functioning o ke keiki a me kona viability, na lako o ka o oxygen ka fetus ma ka piko, e like me ka hiki mā ma fetal? Acaeoey pili me ka circulatory kāna hana a me nā maʻi o ka naau Muscle.

Doppler: rula

E loiloi i ka hopena o Doppler haʻawina hoʻohana i ka kūikawā papaʻaina o nā loina. Ka mea, ke koho i ka pono imua kūmau Fetal Doppler no ekolu nā hoailona:

• Systolic-diastolic lākiō.
• ia'ku inideka.
• Lāʻau ikiʻai wale inideka.

Ia mau haʻawina e hanaʻia nō ia i loko o nā mea a pau hapai wahine, akā, ia mea nui oiaio hoi no ka mea nana e mea ma kamepiula, a he pilikia i ke koko holo, a hereditary mā.

Doppler fetal a vascular ultrasound study ua waeia no ka manawa o 23 pule o ka hāpai keiki. I loko o kēia wā, ke kaʻina hana ka loa i pili i ka helu pūʻulu ka pilikia o complications a me placental malformations, a e alakai i ka hoopau ana i hāpai keiki. Akā, ua haʻawina hiki ke lawe mai e hoʻomaka ana mai ka 13 pule a hiki i ka pauʻana o ka hāpai keiki. Kēlā me kēia pule i kona iho Doppler indices. kēia mau haʻawina a pau e lawe mai i ka makaikai i ka papa kuhikuhiE arteries ekolu: umbilical artery, uterine, fetal aorta.

Anakahi systolic-diastolic lākiō, e hoʻomaka ana mai ka 20 pule o ka hāpai keiki, e ia 2.4 a emi.

ia'ku inideka he pōpilikia no ka mea umbilical artery, uterine, a me MCA. Ke kūmau mea:

• no ka makuwahine - emi ma mua a me ka ewaewa ole i ka 0,58;
• no ka umbilical artery - Ua emi ma mua a me ka ewaewa ole i ka 0,62;
• 'inideka pono e emi ma mua o paha e like me 0,77 o ka waenakonu cerebral artery o ka fetus.

No ka mea lua o ka hapalua o ka hāpai keiki, mau kii aneane ua hoʻololiʻia. A ma ka hope o ka gestation nā hoailona o ka systolic-diastolic hiʻohiʻona e ole oi mau huahelu.

Hōʻike 'ia nā loina

Doppler 3 trimester fetal koko haʻawina a me ka poʻea pau i ke kakahiaka nuiʻike, Kāohi manao placental insufficiency, hana maikaʻiʻole o ka preeclampsia me ka ano loli o ke koko i loko o uterine moku. Ma nä ka emi ana i loko o ia hoʻi, ke diastolic Hawaiʻi, systolic-diastolic lākiō ua nui holomua, a pela, me ka 'ē aʻe' inideka, pōpilikia ma luna o ke kumu o ia mea, ua hoi e māhuahua.

I ka Doppler i loko o ka lua a me ke kolu o kau o ka hāpai keiki kūikawā noonoo ua uku i ka poe akamai i umbilical artery. Ke aʻo hālawa o ke kikowaena artery o ka piko koko e lawe nui ma hope o ka hebedoma umi o ka hāpai keiki. Ma keia kēia lākiō o diastolic koko ka mea hiki ole ke 'akomi i no i ke 14 pule. Ma fetal chromosomal abnormality i mea ano ma 10-13 pule gestation ua maʻamau kākau aʻe diastolic pele.

Ma uncomplicated hāpai keiki i kela systolic-diastolic hiʻohiʻona 'aʻole i oi aku mamua o ekolu iniha, kapuaʻi, ma ka hālawa hōʻike i ke koko. No ka fetal pathology wehewehe aku ma ua hoʻemi pau diastolic māmā holo a hiki i ka piha nalowale.

Ma ka mahina elima o ka hāpai keiki, a hoʻoholumua i ka loa nui PalekanaEND_LINK nā hoailona i noiʻi hua o ke koko. Kaupaona i nā kuhikuhi i ka aorta a me ka waena cerebral artery. Nā aiee o kēia mau lua i pele koko i kiʻekiʻe paepae systolic puʻe loli ma ka aorta, pinepine pu ma ka emi i loko o diastolic hana. Ua uuku ka mea e, i ka luna o ka pilikia o pathologies. Ka loa lakou malaila kulana home 'ole o ka' Aʻohe waiwai diastolic ke keʻena.

No ka waena cerebral artery lapaʻau loli i loko o ke koko kahe i ke ukali, ma ka mea ku ole, he mea ulu ma ka diastolic ke keʻena, a, ma ka huli, mea he kīnā o cerebral hyperperfusion, a hōʻike i ka hooulu ana o fetal hypoxia.

Ma ka like o ke koko i loko o ka venous leki uea systolic kuahiwi noho ma ka hapanui o ka wahi o ka uku kuala o ka hālawa, a ua mohala me abrupt loli kekahi manawa miki pu hou ma ka diastolic ke keʻena o ka pōkole lōʻihi like 'ole. Ke'ī mai, ka mea a pau hālawa mea kūpono kouʻaʻahu me ka hoʻolaʻa pahi kuahiwi. Inā denoted ke kiʻekiʻe kuahiwi o ka systolic ke keʻena, a me ka nalowaleʻana o ka diastolic puʻe, ka mea e hoike i ka chromosomal fetal pathology, e like me ka hanana o fetal hypoxia.

I ka pololei o ka ultrasound Doppler iaoiaeii mea ma kahi o 70%. Ka loa ka hoʻokō o ke ao o ka utero-placental a me fetal-placental koko, i mea aneane hoʻokahi haneri pakeneka hiki diagnose likeʻole kāna hana.

Ka loiloi 'o ka like hualoaʻa

E like me ka mea okoa indices hihia hoʻi ke koko kahe kiko'î e māheleʻia i loko o nā degere he:

• 1 ka papahelu - kēia haunaele ma uteroplacental koko i mau hua placental koko a placental 'aʻe' ana i ka hua me ka unmodified uteroplacental.
• 2 degere - he he hoʻokahi-manawa loli a me ka hoʻohuikau 'ia ma nā' ano o ke koko, i nā hualoaʻa e hiki i kekahi pilikia cia, akā, i ka mea, i wahi e e.
• Grade 3 - o ka loaʻa nui o ka noho pilikia aʻe 'ana i loko o hua'ōlelo o ka hua-placental koko, nānā' ole o ka ina loli paha hoi nīnūnē aʻe 'ana o ka utero-placental koko pele.

Nāʻikepili no ka Doppler hookohu

Fetal Doppler hiki ke lawelawe kekahi manawa, a me ka palua o ka manawa ma hāpai keiki me ka oaeouee? Ina hana. I kekahi manawa ka mea, ua hoakaka hou pinepine ana. Keia ia lŘlŘ ina he mau ka pilikia a me pathologies o ka fetus a me ke koi 'ana o ka uterus a me ka placenta. Aia o kekahi papa inoa o nāʻikepili no i pololei pono e eʻoiaʻiʻo a me ka Doppler pele haʻawina:

• Inā i ka makuahine o ka makahiki, ua oi aku ma mua o 35 a emi o 20 makahiki (kakahiaka ole pō hāpai keiki).
• Polyhydramnios a me oligohydramnios.
• Ma mua like hua mai la ia e ka ultrasound mīkini hōʻike kaula hihia.
• Fetal kūpono 'ana lags ma hope o ka hoʻokumu kūmau.
• Ka makuahine malama loa maʻi maʻi.
• Ka wā mua pregnancies pau i loko o miscarriages a me na keiki i hanau me ka loa mā a me stillborn.
