We describe a case of dextran-induced anaphylactic shock during general anesthesia. A 34-year-old woman was scheduled for partial hepatic resection under general anesthesia. General anesthesia was induced with intravenous remifentanil, thiamylal and rocuronium, and was maintained with oxygen, air, sevoflurane and remifentanil. ⋯ The patient's blood pressure and oxygen saturation immediately improved, and the operation was resumed. No postoperative complications were evident, and the postoperative course was uneventful. Although low molecular weight dextran is often used as plasma expander or to prevent thromboembolism, it can cause severe hypotension or bronchospasm during general anesthesia.

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.
