Tahukah anda "pusingan bayi dari
songsang menjadi kepala dibawah”atau dikenali sebagai "external cephalic version" adalah procedure lama yang telah praktikkan oleh
bidan kampunng zaman dulu? Bezanya ianya
bukan lagi dilakukan oleh mak bidan tetapi oleh doctor terlatih dibawah
pengawasan ultrasound,CTG dan dewan pembedahan.
ECV ini dilakukan pada usia kandungan 36 hingga 37 minggu
kerana awal dari itu bayi akan pusing balik menjadi songsang dan kalau lewat
pula, ia sukar dilakukan kerana air ketuban telah pun berkurangan.
Namun apa yang lebih penting
di sini adalah jika berlaku komplikasi semasa ECV yang memerlukan bayi
dilahirkan secara caesarean!
Sebab itu ECV mesti dilakukan oleh yang telah
terlatih,dihospital yang ada dewan bedah dan pemantauan bayi dengan CTG.
Peratus berjayanya external cephalic version ini mengubah bayi songsang adalah 50% dan dengan ini ia mampu mengurangkan setengah dari
risiko caesarean. Namun kira-kira 3 % akan pusing balik menjadi songsang.
Anda juga perlu tahu bahawa tidak semua ibu yang mempunyai kandungan songsang boleh
melakukan ECV.
