Analgesics and anaesthetics during peripartum period


Our focus in KuBiCo–project is to evaluate the foetal and newborn effects of analgesics and anaesthetics given for parturient during peripartum period. Maternal pharmacokinetics and –dynamics of different compounds used for pain relief and anaesthesia for caesarean section will be measured. Foetal and newborn exposure will be estimated based on the drug concentrations in the placental venous and arterial blood. Pharmodynamic effects of these compounds on newborn will be tested with a comprehensive neurological and adaptive capacity evaluation, and by recording amplitude integrated EEG. All these measures are painless for newborn.
