A 12 month review of infants admitted with neonatal abstinence syndrome to
a neonatal intensive care unit was undertaken. The relationship of maternal
drug abuse to symptoms, the effectiveness of pharmacologic agents in contr
olling symptoms and the length of inpatient stay Here investigated
A retrospective review of maternal and infant records was performed. Those
infants with a serial Finnegan score greater than 8 were treated. Pharmacol
ogic treatment was oral morphine sulphate (0.2mg 4-6 hourly), phenobarbiton
e (3-7mgs/kg/day), or combination of the above.
43 infants were admitted to the hospital during the gear. The average mater
nal age was 24.6 years, (18-34 years). Drug use volunteered by the mothers
was methadone alone in 6 cases, methadone and benzodiazepines in 14, methad
one and heroin and benzediazepines in 7, methadone and heroin in 10, heroin
alone in 2, and other multiple drug use including oral morphine sulphate,
dothiepin and cannabis in 4, Average gestational age was 40.3 (35-42 weeks;
), The average birthweight was 2.81 kgs (1.89-3.91 kgs), Time to onset of w
ithdrawl symptoms was 2.8 (1-13) days. The duration of pharmacologic treatm
ent (oral morphine sulphate and / or phenobarbitone) was 21.8 (1-62) days.
The total hospital stay for the 43 infants was 1,011 days.
This study confirms that polydrug abuse is the commonest type of drug abuse
in Dublin. The duration of withdrawal symptoms is loosely related to drug
type, but increasing duration of symptoms is noted for infants exposed to b
enzodiazepines, Our experience would favour the use of morphine sulphate to
treat pure opiate withdrawal symptoms. Over the 12-month period, there was
an average occupancy of 3 beds per day in the paediatric department.
