Mean ± standard deviation for averaged parasympathetic tone activity (PTAm) (dimensionless), heart rate (HR) (beats/min), mean arterial pressure (MAP) (mmHg), and bispectral index (BIS) (dimensionless), before (pre-stimulus) and 1 and 2 min after four surgical stimuli: pneumoperitoneum insufflation (insufflation), introduction of trocars (trocar), and removal (manipulation and incision) of the left (left ovary) and right (right ovary) ovaries. * Statistically different from pre-stimulus (p < 0.05); † statistically different from 2 min (p < 0.05).
