[Comparative assessment of the hormonal status during N2O and xenon anesthesia using similar methods].

The hormonal status of 38 surgical patients during anesthesia with nitrous oxide and Xe administered by similar methods showed that in contrast to anesthesia with N2O, Xe anesthesia helped not only preserve the adaptive potential, but even increase the defense potential of the organism during surgery. Xe anesthesia was associated with a 1.5 times less requirement in fentanyl, with the levels of stress hormones being better; Xe is the best alternative to nitrous oxide.
