The Feasibility of Bispectral Index Monitoring: RESULTS

In: Anesthesia

16 Sep 2009

An outline of the patients and their preoperative data, preoperative complications, and surgical procedure are given in Table 1. The EMG input and impedance were significantly higher in the IVS group (EMG, 40.3 ± 8.8 dB; impedance, 8032 ± 1237ft; n = 7) than the GA group (EMG, 31.5 ± 9.5 dB; impedance, 4021 ± 1828 ft; n = 7). The SQI and the percentage of “good” EEGs (EEG satisfying all of the following: EMG < 50 dB, SQI > 25%, and impedance < 10 kft; Johansen and Koitabashi’s criteria) during anesthesia were significantly lower in the IVS group (SQI, 71.3 % ± 20.5%; good EEG, 83.3% ± 7.9%; n = 7) than the GA group (SQI, 91.0% ± 18.9%; good EEG, 95.1% ± 2.1%; n = 7) (Table 2).
