About
The aim of this study is to characterize the interest of concentrations in meconium of drugs used for treatment of pregnant opioid-dependent woman as a prognostic factor of time, severity and duration of neonatal abstinence syndrome (NAS). 43 women treated with buprenorphine, 49 with methadone, and their newborns, were included. NAS is assessed by Lipsitz scale. Buprenorphine, norbuprenorphine, methadone, EDDP and morphine are quantified in meconium (one collected immediately after birth, another for 24 to 48 h) by a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, developed and validated for this study.
