Correlation of Surgical Pleth Index with Stress Hormones during Propofol-Remifentanil Anaesthesia

Figure 1

Values are mean±SD. Base: baseline before anaesthesia; Intu: after tracheal intubation; Max: at maximum operative trauma which was defined intraoperatively by the surgeon; After-Max: 15 min after the maximum operative trauma; Mean: mean blood pressure; HR: heart rate; SPI: the group in which remifentanil administration was guided by SPI; Control: the group in which remifentanil administration was guided by standard traditional inadequate anaesthesia criteria. ^∗𝑃<0.05, ^∗∗𝑃<0.01 compared with respective values at Base in the same group with one-way ANOVA followed by LSD test. ^#𝑃<0.05, ^##𝑃<0.01 compared with respective values at Intu in the same group with one-way ANOVA followed by LSD test. ^&𝑃<0.05, ^&&𝑃<0.01 compared with respective values at Maxi in the same group with one-way ANOVA followed by LSD test. No differences were found between the SPI group and the Control group at all four event-related time points (𝑃>0.05).
