This study aimed to evaluate the correlation between the induction to delivery (I-D) time and neonatal plasma drug concentration and anesthesia, as well as its effects on neonates.Methods: Fifty-two parturients in whom general anesthesia was induced for CS were divided into group A (I-D 0.05). The plasma concentration of etomidate in MA and UV was higher in group A than that in group B (P 0.05). The concentrations of etomidate in the MA and UV were negatively correlated with the I-D time (P < 0.05).Conclusion: Prolonged I-D time did not significantly influence the maternal or neonatal plasma concentration of remifentanil. It is safe to administer remifentanil target-controlled infusion in combination with etomidate and sevoflurane for general anesthesia induction during CS.Keywords: cesarean section, placental transport, general anesthesia, remifentanil, etomidate, drug concentration
