Tsanangudzo ye hss. Norm nekupanduka kubva pairi

Kuberekwa zvirokwazvo kunogona kunzi imwe yenguva dzinonyanya kukosha muupenyu hwemukadzi, iyo yaanofanirwa nayo zvakakwana. Nokukurumidza iye achava amai vemurume anodikamwa zvikuru, saka anoedza kutarisira hutano hwake paanenge achiri mudumbu. Kuberekwa kunonyatsochengetedzwa uye kunotungamirirwa navanachiremba kuitira kuti vadzivise matambudziko ose. Imwe yenzira dzakanakisisa yekucherechedza kukura kwe fetus ndeyekuyera moyo wekutsvaga - chss. Chimiro chezvikanda izvi paavhareji zvinofanira kuva pakati pe 120 ne 160 kurohwa paminiti. Zvisinei, munguva yose yehutachiwana, zviratidzo izvi zvinogona kusiyana. Nokudaro, somuenzaniso, panguva yekubata kwemavhiki matanhatu kusvika masere, fetal heart contractions inenge inenge 110 kusvika ku 130 kurova paminiti, pamasvondo 9 kusvika ku10, ine chiyero che 170 kusvika 190, inogona kutaurwa kuti chassis inowanzoitika. Kutanga pavhiki yegumi nemana uye kune imwe nguva yose yekugadzirisa, chirwere chemoyo chemucheche chakanyatsogadziriswa uye chinowanzoita 140-160 kurohwa paminiti.

Zvinonakidza kuziva kuti kuongorora uye kuongororwa kwenhamba yemwoyo kwave kwakashandiswa kwenguva refu kuti kuonekwa kwokutanga kwemucheche yemamiriro ekuberekwa. Scientist Kilian akatove muna 1848 akaratidza kuti mwoyo rhythm yemucheche inogona kuchinja nekuda kwe intrauterine hypoxia. Nemhaka yekufungidzira uku, stethoscope ye obstetric yakagadzirwa uye yakagadzirwa. Yakave yakashandiswa zvakanyanya nenguva iyo masayendisiti akaratidza kuti zvinobvira kutarisa kubatwa kwemoyo zvakanyatsoratidzwa nekubatsira kwe electrocardiogram. Gare gare, kune nzira idzi dzekutsvakurudza, dzakawanda zve ultrasound uye CTG dzakawedzerwa kuwana mufananidzo wakarurama uye wakakwana.

Kusvika parizvino, nekuda kwekuvandudzwa nekugadziriswa kwesayenzi uye teknolojia, hapana chakaoma pakuyera fetal heart rate. Chimiro, chinotsanangurwa muna 120-160 kurohwa, chinoratidza chimiro chechimiro uye chimiro chekuberekwa, asi kukanganisa kwaro kusvika kumaduku maduku kana kukuru kunowanzoita kuti munhu afunge nezve zvikonzero. Ndicho chikonzero, kuitira kuti tisava nematambudziko munekusimbiswa kwema embryo, vakadzi munguva yose yekudzivirira vanoendeswa kuurongwa hwe ultrasound uye cardiotocography.

Cardiotocography ndeyekusanganiswa kwezvibereko zveutterine uye palpitation ye fetus. Migumisiro yekudzidza kwakadaro inogona kupa ruzivo rwakanyanya pamusoro pehupenyu hwemucheche. Kunyanya kunyanya, iyo ECG inoita kuti zvibvirire kuongorora:

- kukosha kwepakati yemwoyo yenhamba;

- mhinduro yemwoyo we fetal kuenda kune kufamba kwayo;

- kuchinja mumoyo wehutachiwana nekuda kwezvipembenene zveuterine;

- kuvepo kwekuderera kana kuwedzera mumoyo wekuraira.

Apo chiremba anoongorora fetus yebhokisi, chimiro chayo chinokosha zvikuru. Izvi zvinokonzerwa nekuti kuwandisa kwechimiro chekuderedza kunogona kuratidza varombo uye huwandu hwekuwedzerwa kwe okisijeni kumucheche. Mamiriro akadaro mumishonga inonzi tachycardia. Asi kudengenyeka kwemwoyo pasi pekugara kunogona kuratidza kuipa kwehuwandu hwemamiriro ehutusi. Kurongedza kunopfuura kudarika 120 / min. Ive inokonzera kukanganisa kusina kukwana kana hypoxia ye fetus. Izvi zvinonzi bradycardia. Mamiriro chete ekuderera kwepfungwa yepamwoyo ndiyo yakasarudzwa ndeyekudzivirirwa kwepelvic ye fetus. Kana iyo embryo, iyo inenge inenge inenge mamiriyoni masere yakareba, isina chido chepfungwa zvachose uye isipo, saka inonyanya kuratidza kubata kusina kusimba. Zvisinei, kuitira kuti arege kukanganisa uye kuti aite zvakajeka kuongorora, chiremba anofanira kuraira mukadzi ane pamuviri achidzokorora ultrasound. Inoitwa kamwe vhiki imwe chete, uye chete pamusana pemigumisiro yakagadziriswa tinogona kuwana tsanangudzo dzakananga.

Zvakakosha kuisa pfungwa dzevakadzi vose kune chimwe chinhu chiduku asi chinonyanya kukosha: kufambira mberi kwema fetus nechokuita kwayo kunobva pane mararamiro ayo mukadzi ane pamuviri anonamatira. Chimiro che fetal heart zvinopesana zvinofanira kushandiswa nenzira yakarurama yekuzorora uye kushanda kweamai vanouya.
