Sufentanil Pharmacokinetics After Intra Amniotic Injection (2IAS)

December 2, 2025 updated by: University Hospital, Lille

Assessment of Fetal and Maternal Sufentanil Pharmacokinetics After Intra-amniotic Injection

The fetus may be exposed during pregnancy to nociceptive stimuli because of fetal pathology (e.g., malformation) or a diagnostic or therapeutic procedure.

To date, there is very little data and no consensus on fetal analgesia. The aim of the investigators study is to evaluate the pharmacokinetics of Sufentanil after intra amniotic injection.
