Does the choice of epidural drug (bupivacaine vs ropivacaine/lidocaine) affect fetal drug exposure in parturients undergoing cesarean section?
Highly lipophilic epidural drugs like bupivacaine and dexmedetomidine have lower transplacental transfer to the fetus compared to less lipophilic alternatives due to rapid maternal clearance and higher volume of distribution.
Tero Ala‐Kokko (1998) conducted an RCT in Elective cesarean section. Ropivacaine or lidocaine-epinephrine vs. Bupivacaine was evaluated on Fetal drug exposure (maternal venous, umbilical venous and arterial free drug concentrations). Epidural administration of bupivacaine led to lower fetal drug exposure compared to lidocaine or ropivacaine during elective cesarean section.
