Fetal position ultrasound is ultrasound examinationin which the gynaecologist assesses the position the foetus is in the womb. It is most commonly performed in third trimesteras the position of the foetus is important for planning the birth.
During the examination, the gynaecologist checks whether the foetus is in cephalic insert (cephalic) - the fetus is upside down. This is the most optimal and most common position for vaginal birth. In addition, the fetus can also occupythe posterior rectum (breech) - the foetus is ass- or feet-facing. In this position, a caesarean section is more often considered, depending on the circumstances, transversely - the fetus lies horizontally. Vaginal delivery is not possible in this position; a caesarean section is required unless the fetus is first turned or oblique position - the fetus is tilted diagonally. This position is usually unstable and may change before birth. Each of these requires a different level of monitoring and sometimes a specific approach to birth planning.
The review is important because determining the mode of deliveryhelps to identify whether the foetus is likely to turn, allows follow-up in women where there is a risk of complications (e.g. multiple pregnancy, too much/too little amniotic fluid, premature placenta) and helps to decide on additional measures such as external fetal reversal (ECV) pelvic position.
If the foetus is at 36-37 weeks still in the pelvic or transverse position, the doctor often suggests additional steps or a consultation on the method of delivery.
UZ is done through the abdomen. The gynaecologist examines the position of the head, body, back and limbs of the foetus and records the current position. The examination is hiter, or and completely safe.
An ultrasound scan to check the fetal position is therefore a crucial part of the preparation for childbirthas it allows for safe planning and timely the most appropriate mode of delivery.
