Experience with remifentanil-sevoflurane balanced anesthesia for abdominal surgery in neonates and children less than 2 years.

Background: Few data report remifentanil use in the neonatal population. We described here our experience with remifentanil-sevoflurane balanced anesthesia in neonates and children less than 2 years who underwent general anesthesia for abdominal surgery.

Methods: We retrospectively studied the pattern of remifentanil infusion associated with sevoflurane inhalation in preterm neonates (PTN; n = 18) (born before 37 weeks of gestation and <45 weeks of postmenstrual age), full-term neonates (FTN; n = 21) (born after 37 weeks of gestation and less than 29 days old) and older children up to 2 years (CUT; n = 24).
