Transcript NEONATAL ABSTINENCE SYNDROME

SUBSTANCE ABUSE
The Drug-Exposed Infant
Authored by: Kathy McKee MS, RNC
OBJECTIVES
List three physiological or behavioral
signs of an infant exposed to drugs in
utero
 Describe use of Neonatal Abstinence
Scoring
 Discuss nursing interventions
appropriate for infants exposed to drugs
in utero

The Statistics

National Institute on Drug Abuse
– 500,000 – 700,000 affected babies annually in
the United States

Washington State
– 12,000 drug affected babies each year
Guidelines for Testing and
Reporting

Screening
– It is the responsibility of every practice to make sure that
all pregnant and postpartum women are screened for
substance use (WA State Dept of Health)

Testing
– Drug testing is based on specific criteria and medical
indicators

Reporting
– Reports of prenatal substance exposure shall not be
construed to be child abuse or neglect and shall not
require prosecution of the mother
Testing

Mom

– Risk Indicators







No prenatal care
Previous unexplained
fetal demise
Precipitous labor
Abruptio placentae
Hypertensive episodes
Severe mood swings
Repeated spontaneous
abortions
– Consent
Baby
– Risk Indicators








Jittery with normal
glucose level
Marked irritability
Preterm birth
Unexplained seizures
or apneic spells
Unexplained IUGR
Neurobehavioral
abnormalities
Congenital
abnormalities
Signs of NAS
– Consent
The Drug-exposed Infant
Transient effects
 Teratogenic effects

– Dysmorphic
– Behavioral

Confounding variables
– Maternal health, socioeconomic status, lifestyle
– Drug used/Poly-drug use
– Use in relation to gestational age
– Time used prior to delivery
Common Findings in Drug
Exposed Infants
Hypersensitivity to stimuli
 Abnormal muscle tone
 Sleep Problems
 Feeding Problems
 GI Problems

Alcohol

Fetal Alcohol Spectrum Disorders/Alcohol
Related Birth Defects
– Growth Restriction
– Facial Dysmorphism




Microcephaly
Short palpebral fissures
Hypoplastic philtrum
Thin upper lip
– CNS Dysfunction


Neurological symptoms
Cognitive & behavioral signs
Nicotine
17% of pregnant women between
the ages of 15 and 44 smoke
 Adverse Effects

– Decreased blood flow through the
placenta
– Low birth weight
– Neurobehavioral impact
– Increased respiratory tract illnesses
– Sudden infant death syndrome
Cocaine

Stimulant
– Tachycardia
– Hypertension
– Decreased blood flow and oxygen delivery to
fetus
– Increased uterine contractions
Effect of Cocaine on the Infant
Irritability
 Poor feeding
 Decreased interaction
 Disorganization
 Sleep disturbances
 Tremors
 Sneezing
 Tone abnormalities
 High-pitched cry

Possible
association with:
–Congenital heart
defects
–Urinary
obstruction
defects
–Gastrointestinal
obstruction
Methamphetamine

Potent stimulant
– Vasoconstriction
– Increased heart rate
– Hyperthermia
– Decreased appetite in user
– Decreased oxygen and nutrient
delivery through placenta
– Prolonged circulation of drug in
fetal circulation
Effects of Methamphetamine
on the Infant
Associated
with:

–Congenital brain
lesions

–Cleft lip

– Disorganized suck
– No suck
–Cardiac defects
–Low birth weight and
reduced OFC
–Hyperbilirubinemia
Poor state control
Lethargic
Poor feeding



Irritable
Abnormal tone
Excoriated buttocks
Narcotics/Opiates
Morphine, Heroin, Methadone
 Continued use will lead to profound
physiologic and psychological addiction
 Neonatal Abstinence Syndrome

– Passive exposure in utero as a
consequence of maternal addiction.
– Iatrogenic exposure by the administration
of narcotic analgesics to the neonate
Neonatal Abstinence
Syndrome
Generalized disorder characterized by
21 symptoms most commonly seen in
withdrawing infants.
 2/3 of infants born to opiate-dependent
women will exhibit signs of NAS
 Time of onset varies
 Symptoms vary

Neonatal Abstinence
Scoring

Assists in the detection of
– Onset of withdrawal symptoms
– Severity of symptoms
– Response to intervention
– Resolution of symptoms

Assess high risk infant
– 2 hours after birth
– Every 3-4 hours
NAS Scoring

The Finnegan scale
– If score is 8 or greater

Score every 2 hours for 24
hours
– Scores > 8 on three
consecutive scores

Evaluate need for
medication
– If intervention not needed
by 72 hours

Scoring may be
discontinued
System Disturbances
 Central
Nervous System
 Metabolic/Vasomotor/Respiratory
 Gastrointestinal
Central Nervous System








Cry
Sleep pattern
Exaggerated Moro Reflex
Tremors
Muscle tone
Excoriation
Myoclonic jerks
Convulsions
Metabolic,Vasomotor,
Respiratory
Sweating
 Fever
 Yawning
 Mottling
 Nasal stuffiness
 Sneezing
 Nasal flaring
 Increased respiratory rate, retractions

Gastrointestinal
Excessive sucking
 Poor feeding
 Regurgitation, projectile vomiting
 Loose stools, watery stools

Medications for NAS
Morphine Sulfate
 Phenobarbital
 Ativan
 Other

Nursing Care of the Drug
Exposed Infant





Careful Assessment
NAS Scoring (if opiate exposure)
Control of the environment
Feeding techniques
Therapeutic Handling
–
–
–
–
Swaddle
Clapping
Vertical rocking
C-position
Nursing Care of the Drug
Exposed Infant

Dealing with the family
– Personal feelings
– Public health issue vs. Crime
– Involve in care—teach
Opportunities for changing the addicted
woman’s behavior and her view of health care
providers can be influenced by the care she
and her infant receive while hospitalized
