Scanlon et al developed the early neonatal neurobehavioral scale (ENNS) for evaluating neonates born to a mother receiving epidural anesthesia. This can be used to evaluate the infant's response to drugs given to the mother during delivery.
The score is modified by Amiel-Tison et al. This modfiicatio was further modified by addition of a borderline score (with 0.5 points).
Elements:
(1) score based on 15 measurements
(2) global assessment
Parameters:
(1) response to pinprick
(2) habituation to repeat pinprick
(3) pull to sitting
(4) arm recoil
(5) truncal tone
(6) general body tone
(7) rooting
(8) sucking
(9) Moro response
(10) habituation to Moro response
(11) habituation to light in eyes
(12) response to sound
(13) habituation to sound
(14) placing reaction (the infant is suspended in the upright position and the dorsum of the foot is applied to a protruding edge)
(15) alertness
where:
• The response to light in the eyes could be added, in addition to the habituation item.

Interpretation:
• minimum ENNS: 0
• maximum ENNS: 15
• The higher the score the more normal the infant. A score >= 12 indicates a good neurobehavioral status.
• If the effect is due to a drug, then it should improve as the drug is eliminated. If it is due to disease then it should persist.
