Kuongororwa kunoitwa sei uye rini?
Kazhinji kazhinji mumamiriro ezvinhu akadaro, ultrasound is transabdominal, i.e. iyo sensor inowanikwa pamadziro emadziro emukati. Chinodiwa ndicho chidzara chakazara. Saka, musati watanga nzira, mukadzi, kunyanya kwema1-1,5 maawa asati apera, unoda kunwa 500-700 ml yemvura. Kana chidzidzo chacho chaitwa mangwanani, mukadzi wacho anorayirwa kuti arege kutora maawa 3-4.
Maererano nemitemo, ultrasound pakutanga kuongorora inoitwa pamasvondo gumi nemaviri ekuzvitakura. Panguva imwecheteyo, nzira yakadaro inobvumirwa mukati memavhiki gumi nemaviri ekupedzisira.
Chii chinonzi ultrasound chinoratidzira pamasvondo gumi nemaviri ekuzvitakura?
Chidzidzo chekufambira mberi kwekufambisa kunoitwa pamwe chete pamiganhu yakawanda. Zviratidzo zvikuru izvo zvinofananidzwa nehutsika uye nguva dzose zvinofungidzirwa pa ultrasound muvhiki yechipiri yekutakura ndezvi:
- KTP - coccygeal parietal size. Nharaunda kubva pamucheto weparietal bone kusvika ku coccyx yakagadzirirwa;
- BDP - biparietal size - kureba pakati pe 2 parietal tubercles;
- TVP - ukuru hwekoro nzvimbo.
Kugadzirisa migumisiro yekudzivirira pamasvondo gumi nemaviri e-ultrasound uye kuenzanisa nemitemo inoshandiswa navanachiremba vachishandisa tafura.
Panguva imwe chete, vanachiremba vanosimbisa zvakare:
- kuenzanisira kukura kwehutachiona hwemhepo, kubhadhara zvakanakira chimiro;
- kuongorora basa remwoyo yematambudziko, nekugadzirisa kushaya mwoyo;
- chengetedza kukura kwechimiro chema fetus nekuyera urefu hwepafudzi, chidya, shin, forearm.
Kunyatsotarisa mukutsvakurudza kwakadaro kunobviswa nekuongorora iyo placenta, kugadzirisa kubwinya kwayo uye nzvimbo yekubatanidza. Mukuwedzera, chiremba anonyatsotarisa tsambo yembilical, nokuti zvakananga kuburikidza nayo chibereko chinogamuchira zvinhu zvinobatsira uye oksijeni. Kusiyanisa pakati pehukuru hwemidziyo uye chimiro chinogona kuratidza nenzira yakananga mukana wekuvandudzwa kwehupenyu hwekukanda kwomweya wezvakakomba, izvo zvinozokanganisa zvakanyanya kukura kwayo.
Nokudaro, sezvinogona kuonekwa kubva munyaya yacho, ultrasound pavhiki yekubata pamuviri 12 ndeimwe yezvidzidzo zvakakosha zvinogona kuona kutyorwa munguva yepakati pfupi.
