An ultrasound device that costs only 30 risks falsely reassuring parents about their unborn baby’s health.

Fetal dopplers allow mothers to listen to the heartbeat of their baby in the womb. However, they were never intended to be used without the necessary training.

In October I will present my ten-minute-rule motion to parliament to regulate the sale of these devices. following concerns first raised with me by the charity Kicks Count.

As Will Quince, co-chairman of the all-party group on baby loss has written in this space previously, the government aims to cut the stillbirth and neo-natal death rate by 20 percent by 2020 and 50 percent by 2030. The UK’s stillbirth and neonatal death rates are the third worst in the developed world. This is not simply a parental problem, but a healthcare problem on a systemic level. How a stillbirth can affect your life by giving your lifelong trauma and other physical problems is something no mother wants to know. However, medical negligence and the improper use of fetal dopplers are causing it to happen all too often. If we are to cut the stillbirth and neo-natal death rate by 2020, we must ensure that baby health is monitored to the very highest standards.

Fetal dopplers simulate a sound by sending ultrasound waves into the abdomen which reflect off any movement. This could be the baby’s heartbeat but could also be the mother’s moving blood vessels or other unrelated sounds. Midwives train for three years using the highest quality equipment in order to detect heartbeats. If mothers ignore changes in their babies’ kicking or moving in the womb and rely on a device that can be bought over the counter the result could potentially be fatal.

Furthermore, even if home dopplers could flawlessly detect a baby’s heartbeat it is still not a sufficient measure of its health. A heart can continue to beat despite other serious issues being present.

The NHS Choices website describes the monitors as “potentially dangerous to the mother and baby’s health”. The Royal College of Midwives says that “expectant mothers have been warned against the use of home fetal doppler devices over fears that they may give false reassurances about the health of their baby.”

Vicky McNelly, from Reading, lost her baby after delaying seeking medical advice because she had heard her baby’s heartbeat on a home doppler.

“I’d used a home doppler a handful of times throughout my pregnancy,” she said. “We loved being able to listen to her heartbeat for as long as we wanted. I didn’t do it for reassurance at first, it was purely for fun and to feel even closer to her.

“My baby was two weeks overdue when I woke up in the early hours of one morning around 3am and I didn’t feel right. I felt unsettled but I couldn’t put my finger on what was wrong. I went downstairs and sat on my pregnancy ball and after a few minutes of knowing that Evie’s movements had changed I got out the doppler and tried to listen for her. I heard some noises but not the same ones.”

More than 12,000 people have signed a petition calling for dopplers to be banned.

It is extremely welcome that Mothercare announced in June that doppler devices would be discontinued once current stocks run out but with sales rising and work to raise awareness of the risks clearly not taking effect it is important to regulate the market.
