Assessment
Primary outcomes
Anesthetic concentrations in maternal venous blood before conversion to cesarean section, and in maternal venous blood and umbilical venous blood at the time of cesarean delivery.
Key secondary outcomes
Associations between anesthetic concentrations (in maternal venous blood before conversion to cesarean section and in maternal venous and umbilical venous blood at the time of cesarean delivery), drug dosage, timing of administration, and maternal and neonatal conditions.

Other
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.
