RCOG reduced fetal movements guideline urgent assessment fetal movements

Reduced fetal movement at 32-33 weeks needs assessment today at the maternity hospital or obstetric emergency unit, even though this scan contains several reassuring findings. If she cannot feel movements now, or they are much less than usual, go immediately. Do not wait until tomorrow or rely on eating/drinking something to see if it improves.

What this report shows

  • Single live fetus, head-down position.
  • Heart rate 148/min, which is within the usual fetal range.
  • Movements and cardiac activity were seen at the time of the scan.
  • Amniotic fluid is normal: AFI 13.9 cm.
  • Estimated weight about 1996 g, around the 32nd percentile, so not classified as growth restricted from this measurement.
  • No obvious structural anomaly was detected on this scan. It is explicitly not an anomaly scan.
  • Placenta is fundal, grade III. This alone does not diagnose a problem, but needs to be considered by the obstetrician in the context of reduced movements and fetal monitoring.

About “MCA-low”

The report shows MCA peak systolic velocity (MCA-PSV) 32.15 cm/s = 0.72 MoM.
This result is not suggestive of fetal anemia. MCA-PSV is mainly used to screen for fetal anemia, where the concerning finding is an elevated value, typically above about 1.5 MoM, not a low value. A value of 0.72 MoM does not mean low blood flow to the brain, low intelligence, or fetal brain damage.
It may be worth asking the doctor whether they meant a different MCA measure, such as MCA pulsatility index or the cerebroplacental ratio, since those values are not visible in this report.

What should happen now

Because she reports reduced movement, she should be assessed today, typically with:
  1. CTG/NST fetal heart-rate monitoring, usually for at least 20 minutes.
  2. Maternal blood pressure and urine protein check.
  3. Obstetric review of the ultrasound, growth, fluid, placenta, and Doppler studies. The report does not show umbilical artery Doppler or a full placental-insufficiency Doppler assessment.
  4. Further monitoring or repeat scan as the obstetrician advises.
Current RCOG guidance states that any decrease or change in fetal movements should be reported and assessed, with priority given to confirming fetal wellbeing and excluding urgent problems. See the RCOG reduced fetal movements guidance.

First child with delayed development

That history is important, but it cannot be linked to this MCA reading. A normal late-pregnancy ultrasound cannot exclude many genetic, metabolic, neurodevelopmental, hearing, or developmental conditions.
The obstetrician should review:
  • The first child’s exact diagnosis, developmental assessment, genetic-test results if any, and medical records.
  • Whether referral to a fetal medicine specialist and genetic counselor is appropriate.
  • Whether parental carrier testing or targeted testing in pregnancy is indicated. This depends entirely on the first child’s established diagnosis, if known.

Go urgently now if

  • No movements are felt
  • Movements remain clearly less than her normal pattern
  • Vaginal bleeding, leaking fluid, strong abdominal pain/contractions
  • Severe headache, blurred vision, upper abdominal pain, sudden swelling, or high blood pressure
A reassuring scan is helpful but does not replace same-day CTG assessment when movements have reduced. Recent evidence also continues to identify reduced fetal movement as a situation needing careful risk assessment, particularly when growth restriction or hypertension coexist (PMID 40091517).

She went and doctor gave her betnesol injection

WHO antenatal corticosteroids preterm birth betamethasone recommendation 2025

Betnesol is betamethasone, a corticosteroid injection given in pregnancy to help the baby’s lungs mature if the doctor thinks there is a meaningful possibility of delivery before term, often within the next 7 days.
At 32-33 weeks, this is a common and appropriate precaution if the doctor is concerned about fetal wellbeing, possible early delivery, preterm labor, or another reason delivery might be needed. It does not itself mean that delivery is certain or that there is brain damage.
Usually it is given as a short course, commonly two injections 24 hours apart. Follow the exact schedule the obstetrician gave. WHO describes IM betamethasone in divided doses totaling 24 mg for pregnancies with a high likelihood of preterm birth. WHO recommendations
Important next steps:
  • Confirm whether she needs the second injection and when.
  • Ask if her CTG/NST was reassuring, and whether admission, repeat Doppler, biophysical profile, or early delivery is being considered.
  • Continue to observe her baby’s usual movement pattern. If movements are again clearly reduced, absent, or concerning after returning home, go back to the hospital immediately, even if she has received Betnesol.
  • If she has diabetes or high sugars, her blood glucose may rise temporarily after steroid injections and should be monitored by her clinical team.
The injection is intended to reduce breathing problems and some complications if a premature birth occurs. It is not treatment for “low MCA,” nor does it establish a developmental problem in this baby.
