Objectives
Narrative objectives1
We measure maternal and umbilical blood anesthetic concentration in the case of conversion from labor analgesia to cesarean section using ropivacain and fentanyl. We study the relationship between the anesthetic concentration and neontal health status.

Assessment
Primary outcomes
We asses the neonatal health status immediately after birth. The neonatal health status includes Apgar score, umbilical cord artery blood pH, neonatal resuscitation, and admission to the NICU/GCU.
Key secondary outcomes
We evaluate the condition of the mother from the beginning of anesthetic administration for cesarean section to the end of cesarean section. We evaluate the presence of local anesthetic systemic toxicity and respiratory depression as a maternal condition.

Other related information
We measure maternal venous anesthetic concentraion before drug administration and at delivery. We also measure umbilical venous anesthetic concentration at delivery.
We study the relationship between the anesthetic concentration and neonatal health status. The neonatal health status includes Apgar score, umbilical cord artery blood pH, neonatal resuscitation, and NICU/GCU admission.
We study the relationship between the anesthetic concentration and maternal health status.
Maternal status includes the presence or absence of local anesthetic systemic toxicity and respiratory depression.
