Opioids most common cause
🩺 Signs
High-pitched cry, irritable, jittery
Tremors, hypertonia, poor feeding
Diarrhea, sweating, sneezing, yawning

📚 Neonatal Abstinence Syndrome — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Neonatal abstinence syndrome (NAS) is a constellation of withdrawal signs in a newborn exposed in utero to opioids or other substances. After birth the maternal drug supply is cut off, producing central nervous system irritability, autonomic instability, and gastrointestinal and respiratory disturbances. Care centers on a quiet, low-stimulation environment, scoring of withdrawal severity, and sometimes pharmacologic weaning.
🔑
Key points
Understand these first
Classic signs are a high-pitched cry, hyperactive reflexes/tremors, irritability, poor feeding, and a difficult-to-console state.
Other findings include excessive sucking, frequent yawning/sneezing, sweating, nasal stuffiness, diarrhea, and poor weight gain.
A standardized tool (e.g., Finnegan scoring) guides assessment and pharmacologic treatment decisions.
Pharmacologic management may use morphine or methadone with gradual weaning for opioid withdrawal.
A swaddled, quiet, dimly lit environment with minimal stimulation reduces irritability.
Skin breakdown from frequent loose stools and constant movement is a common complication.
✅
Nursing priorities
What to do, in order
Provide a calm, low-stimulation environment: swaddle snugly, dim lights, reduce noise, and cluster care.
Assess withdrawal severity with a scoring tool and administer/wean medications as ordered.
Offer small, frequent feedings and monitor weight, intake, and output.
Protect skin integrity, especially the diaper area and chin/knees from rubbing.
Support maternal-infant bonding and connect the mother to substance-use resources without judgment.
🚩
Red flags — report now
Escalate immediately
Report seizures, apnea, or inability to console/feed.
Report poor weight gain, dehydration, or severe diarrhea/vomiting.
Report rising withdrawal scores indicating need for or escalation of medication.
🧪
Labs & values
Numbers to know
Neonatal/maternal urine or meconium drug screen (positive confirms exposure)
Monitor weight and glucose for adequacy of intake
🗣️
Patient teaching
What patients must know
Teach caregivers gentle soothing: swaddling, vertical rocking, a pacifier, and a quiet dim room.
Explain the importance of small frequent feeds and tracking weight.
Provide nonjudgmental support and referrals for maternal recovery and follow-up care.
