    The effectiveness of three treatment regimens used in the management of neonatal abstinence syndrome
    Khoo, Khooi Tin ( 1995-09)
    This study proposed a multifactorial model of development to understand the development of infants during their first 12 months of life who had been born to chemically dependent women. The impact of maternal chemical dependency on pregnancy outcome, factors associated with severity of neonatal abstinence syndrome and effectiveness of three treatments used in the management of neonatal abstinence syndrome was studied in 271 mother-infant pairs, who were managed by the Chemical Dependency Unit, Royal Women’s Hospital, Melbourne between April 1991 and May 1994. The chemically dependent mothers and their infants were grouped on the basis of their primary drug of abuse: viz methadone, heroin, non-opioid and codeine groups. Fifty two infants born to drug-free mothers were recruited from a routine antenatal clinic of the same hospital to serve as a control group. The controls were matched for maternal age, marital status, race socioeconomic status, educational level, alcohol and tobacco consumption. Patterns of maternal drug use were determined by reports from methadone treatment programs, drug rehabilitation centres, medical records, personal interviews and urine toxicologic assays performed on mothers during pregnancy and on their infants during the first 48 hours of life. Urine was assayed for metabolites of methadone, amphetamines, barbiturates, cocaine, opiates, cannabis and benzodiazepines. There were 180 heroin-dependent, one morphine-dependent and one pethidine-dependent pregnant women enrolled in methadone maintenance programs. The methadone group consisted of these 182 methadone-maintained women and their offspring. Thirty five heroin-dependent women and their offspring formed the heroin group. The non-opioid group consisted of 46 chemically dependent women who used multiple drugs but not opioid drugs during their pregnancy and their offspring. There were eight mother-infant pairs in the codeine group. The mothers in this group primarily abused medication containing codeine in pregnancy. (For complete abstract open document)
