Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Goal: Three different drugs are used in a randomised, double blind, clinical multi-centre trial with three arms. Major objective is to investigate the duration of drug treatment based on the Finnegan score. Secondary objectives are to document weight gain, the need for adding a second drug when the first drug is not effective enough and possible side effects such as convulsions.
Methods: Neonates born after 34 completed weeks of gestation with meconium proven antenatal opiate exposure and parental informed consent are included. Infants with severe malformation are excluded. Each infant is assessed every eight hour by a modified Finnegan score. When 9 points are exceeded drug treatment is started and dose increased stepwise according to the score. The masqued solution applied orally contains morphine, phenobarbital or chlorpromazine. When the maximum dose does not reduce the score, a second randomisation and one of the two remaining drugs is added, again in a blinded way.
A total of 120 infants, 40 in each group will be included in the study.
