Bakeng sa bokhachane bohle, mosali o fuoa bonyane lipatlisiso tse tharo tse entsoeng tsa ultrasound. Libeke tse mashome a mabeli a metso e 'meli (32), mochine oa boraro o hlophisitsoeng oa ultrasound ea fetus Morero o ka sehloohong oa tlhahlobo ke ho bona hore na ho ka etsahala'ng ho lieha ho ntlafatsa botalatsi le ho hlahlojoa ha placenta. Joaloka lihlohlolong tse fetileng - libeke tse mashome a mabeli le metso e 'meli, ngaka e shebile litekanyo tsa mokokotlo oa hlooho, mpa le boholo ba litho tsa' mele.

Qetellong mabapi le lipatlisiso tse entsoeng ke ngaka, ho boleloa hore na bokhachane bo boleloa joang, ke hore na boholo ba tholoana bo lumellana le mekhoa e tloaelehileng ea nako e itseng.
Li-ultrasound libeke tse 31-32 tsa bokhachane ha e le hantle li na le sepheo sa ho ithuta lesea la lesea feela, empa hape le placenta. Setsebi se khetholla sebaka sa sona le lerako leo e leng ho lona. Tlhahisoleseding ena ke ea bohlokoa e le ho fumana mokhoa oa ho pepa, 'me o bohlokoa haholo haeba ho na le lintlha tsa karolo ea ho tlohela. Ha ho hlahlojoa placenta, ngaka e tsamaisang bokhachane e etsa hore ho itokisetse ha khalala ea mosali ho ea pepelong.
Ho kenyelletsa di-ultrasound ka libeke tse 32 tsa bokhachane
Litlhaloso tsa ultrasound libeke tse 32 tsa bokhachane li bapisoa le litafole tse ikhethang, tse hlophisitsoeng ho latela mekhoa ea ho hōla ha lesea ho ea nakong e itseng ea bokhachane. Haeba likarolo tsa ultrasound libeke tse 32 li fapane le tse tloaelehileng tsa bohlokoa bakeng sa beke kapa libeke tse peli, sena hase phapang. Ke habohlokoa ho hlokomela hore setho se seng le se seng se na le batho ka bomong, 'me mekhoa e amohelehang ka kakaretso ke likopano feela. Ka beke ea mashome a mararo a metso e 'meli ea litefiso tsa bokhachane li shebahala joaloka tsena:
