Reduced fetal movement assessment

Absent movement may signal fetal compromise or death

A sudden decrease, weakness or cessation of the baby's usual movements, especially with pain, bleeding, fluid loss, maternal illness or a period of unusually vigorous movement, needs immediate maternity assessment and must not wait until the next day.

Action: Tell the patient to contact or attend the maternity unit now; confirm fetal heart activity promptly, assess maternal observations and obstetric symptoms, and arrange computerised CTG from 26+0 weeks plus indicated ultrasound and senior review.

Synopsis

Respond to a pregnant person's subjective change in fetal movement without delay, use gestation-specific assessment to identify death, acute compromise or placental dysfunction, and plan recurrent or term presentations safely.

  • From 24+0 weeks, advise immediate contact with maternity services at any time of day or night for concern about reduced, weaker or absent movement; do not instruct the patient to wait until morning.
  • Normal movement varies between pregnancies, so use the baby's established pattern and the patient's concern; there is insufficient evidence for a universal numerical kick-count threshold.
  • Movement type changes near term, but frequency and strength do not normally decline in the third trimester and movement remains expected through labour.
  • Confirm fetal heart activity with a handheld Doppler in every presentation, including before 24 weeks, then avoid delaying ultrasound if viability remains uncertain.
  • Assess fetal size, symphysis-fundal height when not already on serial scans, maternal blood pressure, urinalysis and risk factors for fetal growth restriction or stillbirth.
  • After viability is confirmed, arrange computerised CTG from 26+0 weeks to exclude acute fetal compromise; interpret any abnormality with immediate senior obstetric input.
  • After 28+0 weeks, perform ultrasound when reduced movement persists despite a normal CTG or an additional growth-restriction or stillbirth risk exists, provided no scan has been performed in the preceding two weeks.
  • Normal CTG, growth, liquor and Doppler do not require automatic birth, but recurrence prompts fresh assessment and presentation after 39+0 weeks supports individualised discussion of expediting birth.

    • Key red flags

    No fetal heart detected with a handheld Doppler requires urgent ultrasound confirmation by an appropriately trained clinician and sensitive communication; do not prolong repeated bedside searching.

    An abnormal computerised CTG, persistent fetal bradycardia or tachycardia, recurrent decelerations or another sign of acute compromise requires immediate senior obstetric review and a gestation-appropriate birth decision.

    Reduced movement with vaginal bleeding, severe abdominal pain, uterine tenderness, trauma, fluid loss, hypertension symptoms, fever or maternal collapse requires simultaneous emergency maternal and fetal assessment.

    Reduced movement plus suspected small-for-gestational-age fetus, oligohydramnios or abnormal umbilical artery Doppler suggests placental dysfunction and needs specialist fetal-growth management.

    Repeated reduced-movement presentations are not explained by one earlier normal test and require reassessment for predisposing causes and placental or fetal compromise.

    A patient reporting sudden excessive, frantic or unusually vigorous movement followed by reduced or absent movement should be assessed urgently rather than reassured by the earlier activity.

    Investigation priorities

    01
    Handheld Doppler fetal-heart auscultationFirst step

    Confirm fetal cardiac activity promptly at every presentation across gestations.

    Management branches

    Immediate contactTake the report seriously

    The patient notices fewer, weaker, absent or unusually changed fetal movements.

    1. Establish gestation, time and nature of change, current movement and associated bleeding, pain, fluid loss, illness or hypertension symptoms.
    2. Advise immediate maternity assessment when concern persists, without requiring food, cold drinks, home Doppler use or a fixed count before attendance.
    3. On arrival, assess maternal physiology and obstetric symptoms and confirm fetal-heart activity promptly with urgent ultrasound if it cannot be detected.
