Results
The present study is a follow-up on our earlier research series, and is based on reanalysis of the data obtained from the previous research series.
To estimate ICP during sedation and anesthesia, we analyzed the data from 124 healthy male volunteers whose waveforms were available for calculation of nICP in the previous research series.
The effects of nitrous oxide inhalation sedation on nICP was published in JOURNAL OF THE JAPANESE SOCIETY FOR DISABILITY AND ORAL HEALTH .

The present study is an additional analysis of the previous data. The previous data are obtained from an intervention experiment in which healthy adult volunteers were administered various sedative and anesthetic drugs, such as sevoflurane (n=18), nitrous oxide (n=20), dexmedetomidine (n=18), propofol (n=24), and midazolam (n=44). The written informed consent was obtained in the original study approved by the IRB.
