Out of 4.3 million babies born per year, between 800,000 and
1 million are born to women who used drugs during
pregnancy.
Alcohol
Nicotine
Illegal drugs
5.4 million children in the United States live with a parent
who has a substance abuse disorder.
3.4 million live with a mother who has a substance abuse
disorder.

Neonatal abstinence syndrome is the clinical term used for
opiate withdrawal in the newborn.
Characterized by the development of specific withdrawal signs
after birth, usually presented between 48 and 72 hours.
It is estimated that between 48 and 94% of infants exposed to
opiates in utero develop clinical signs of withdrawal after
delivery.
WHAT IS NAS?
![Page 4: Neonatal abstinence syndrome](https://reader038.vdocuments.us/reader038/viewer/2022100518/559e01b81a28ab1e6a8b460f/html5/thumbnails/4.jpg)
Babies who are born to substance abusing mothers are at risk
for developing NAS.
They are scored using the Finnegan system by the nurses in
the NICU. There are 3 categories:
Central nervous system disturbances
Metabolic/vasomotor/respiratory disturbances
Gastrointestinal disturbances
According to the scores given by the nurses, the decision is
then made whether or not the baby requires treatment for its
symptoms.

Much like in the CP project, we can use the accelerometer
technology to measure patterns of movement in NAS babies.
Develop subjective, automated system for scoring the NAS
babies’ symptoms.
Treat symptoms earlier
Avoid over-/under-treating
Decrease need to trust parents
Send babies home sooner
HOW CAN WE HELP?

There are several ‘movement -based’ symptoms that could potentially be measured using our technology:
Tremors
Seizure activity
Moro reflex
Muscle tone?
Respiratory rate
According to Dr. Joan Fisher, the tremors are a universally presented sign of withdrawal. This may be our best bet.
C. O’Brien and colleagues are already using the Actigraph to compare clinical scoring with measure of movement.

Wireless sensors
One per baby, not needed on all 4 limbs
IRB probably won’t allow wired sensors
Remotely accessible by clinicians
Sync with electronic chart and medical records
Objective data not dependent on observer
