Pregnant women who undergo at least one additional ultrasound before giving birth have a better chance of avoiding cesarean deliveries.
In a study published in the journal PLOS Medicine
Researchers at the University of East Anglia and the University of Cambridge found that a second ultrasound scan about a month before delivery could reduce the risk of babies' birth with their feet or bad.
The condition
, known as the presentation of the undiagnosed seat, poses a significant risk to the health of the mother and her child. Doctors often recommend an emergency caesarean section to make sure both deliver safely.
If the cases of presentation of the seat are detected several weeks before the birth of the child, the researchers think that this can contribute to reduce by 4,000 the number of procedures of emergency caesarean section each year.
Undiagnosed seat presentations
Gordon Smith, professor of obstetrics and gynecology in Cambridge, led his colleagues to examine
undiagnosed seat presentations in the United Kingdom. They asked 3,879 women, who were living their first pregnancy, to undergo an ultrasound at 36 weeks.
Although only 179 pregnant women (4.6%) were diagnosed with a siege, more than half of them said they did not receive any previous indication that their baby was in such a state. .
Pregnant women usually receive an ultrasound as they reach their twentieth week. However, because badessments depend heavily on the ability of physicians to feel the bumps of their patients, most cases of seat presentation are often not detected.
Asking patients to be screened during their 36th week of pregnancy has given them the opportunity to opt for the external cephalic version, in which doctors try to rotate the baby to place it in the correct birth position.
The study suggests that the procedure one month before delivery
dramatically increases its success rate only if it is made close to delivery.
Some participants opted for an external cephalic version. For patients who refused, or when the procedure did not work, the researchers planned a planned cesarean section.
None of the pregnant women chose to undergo a badl seat birth. The procedure may be an option for seat presentation cases, but it still involves security risks.
.
Of the 179 women diagnosed with siege, 19 were able to give birth badlly, 110 underwent scheduled cesarean delivery and 50 had emergency cesareans.
Implications of late ultrasound
Smith and his colleagues are already studying the possibility of implementing low cost late ultrasounds. This can be done by incorporating screening into midwife standard appointments and using portable ultrasound devices that are more affordable than regular machines.
If the cost of diagnosis was to be reduced to just £ 20 ($ 26) per patient, Smith stated
it would be more profitable. Even if the procedure were to be performed for less than £ 13 ($ 17), the National Health Service would still save more money in the long run.
Some doctors are now calling on the NHS to explore
the possibility of making ultrasound screening more cost effective, while others are still asking for more testing to be done before implementing such a move.
