Fetal tone and reflex
Amniotic liquid
Fetal heart rate reactivity


Score :

What is the interest of the biophysical profile?

• Look for fetal hypoxia and acidosis

• Avoid death in utero

• Decrease the rate of false-positive fetal heart rate

MANNING Biophysical Score

Parameter: Respiratory movements, Global movements, Tonus, Amniotic fluid and CTG

With regard to the ultrasound parameters, the observation lasts a maximum of 30 minutes but stops as soon as all of these criteria are met.

Scores of 8 to 10 are considered normal, with a reassuring prognosis for one week, except for outdated terms.

Score at 6: New evaluation at 24 hours

Score less than or equal to 4: Terminate the pregnancy, because probable fetal distress

In practice, when this score is limited, the umbilical and cerebral Dopplers must be added.

What are the factors influencing the biophysical score?

• Inhibited by drugs

– Morphine

– Heroine

– Methadone

• Stimulated

– Hyperglycemia

– Catecholamines

Manning score is correlated with fetal pH

- Score 4 => pH < 7.30 for 50%

- Score 2 => pH < 7.25 for 75%

What is the effect of fetal hypoxia on the biophysical score?

• Acute hypoxia

– decrease in the reactivity of the fetal heart rate.

– decrease in respiratory movements.

• Chronic hypoxia

– decrease in the reactivity of the fetal heart rate.

– decrease in respiratory movements.

– decrease in fetal movements.

– decrease in fetal tone.

– decrease in the amount of liquid.
