Stress hormone changes in general anesthesia of long duration: isoflurane-nitrous oxide vs sevoflurane-nitrous oxide anesthesia

In inhalation anesthesia with the duration of more than 10 hours, isoflurane-nitrous oxide and sevoflurane-nitrous oxide had the same effects on stress hormone changes except for epinephrine, norepinephrine, and ADH. Epinephrine, norepinephrine, and ADH concentrations were higher in isoflurane-nitrous oxide anesthesia.
