Neonatal withdrawal or neonatal abstinence syndrome (NAS) or neonatal opioid withdrawal syndrome (NOWS) is a withdrawal syndrome of infants after birth caused by in utero exposure to drugs of dependence, most commonly opioids. Common signs and symptoms include tremors, irritability, vomiting, diarrhea, and fever. NAS is primarily diagnosed with a detailed medication history and scoring systems. First-line treatment should begin with non-medication interventions to support neonate growth, though medication interventions may be used in certain situations.In 2017, approximately 7.3 per 1,000 hospitalized infants in the United States were diagnosed with NOWS. Not all opioid-exposed infants will show clinical signs of withdrawal after birth. Clinical signs range from mild to severe, depending on the quantity and type of substance exposure.The most common form on neonatal withdrawal occurs after in utero exposure, however, iatrogenic withdrawal can also occur after medications are used to treat critically ill infants after they are born. Signs and symptoms
Drug and alcohol use during pregnancy can lead to many health problems in the fetus and infants, including neonatal abstinence syndrome (NAS). The onset of clinical presentation typically appears within 48 to 72 hours of birth but may take up to 8 days. The signs and symptoms of NAS may be different depending on which substance the mother used.Common signs and symptoms in infants with NAS may include:
Signs due to hyperactivity of the central nervous system:
Tremors (trembling)
Irritability (excessive mood crying)
Sleep problems
High-pitched crying
Muscle tightness
Hyperactive reflexes
Seizures (2% to 11%), notably this clinical sign is controversial given it does not occur in other populations experiencing opioid withdrawal.
