Case Reports
[Anesthetic machine leakage from vaporizer by external force derived from keyboard of electronic medical records].
We experienced the leakage from the vaporizer of the anesthetic machine despite the normalities on performing the initial leak test. The vaporizer of the anesthetic machine was compressed by computer keyboard of EMR which caused a leak from vaporizer. After computer keyboard and the vaporizer were set at normal position, the leak stopped.

Comparative Study
[Is nitrous oxide useful for laryngeal mask airway insertion under 8% sevoflurane?].
The usefulness of nitrous oxide for laryngeal mask airway insertion under 8% sevoflurane anesthesia was investigated. ⋯ Nitrous oxide shortened induction time, decreased hemodynamic changes, but did not increase postoperative nausea, vomiting and headache when used for anesthesia induction with 8% sevoflurane to insert laryngeal mask airway.

The bispectral index (BIS) is widely used to measure anesthetic levels in the perioperative period. In our hospital, the BIS monitors (A-2000) are connected to bedside monitors and display BIS values on them through outside input. ⋯ One possible reason is thought that the BIS Quatro Sensor transmits both EEG signals and sensor information to the BIS A-2000 monitor separately. BIS A-2000 monitors may process EEG signals and sensor information individually, and transfer BIS parameters to the external equipments, regardless of sensor information.
