2. Figure 1
Procedure diagram. (a): Intra-abdominal view of 2-0 byosin suture penetrating the abdominal wall. The needle is manipulated inside the abdominal cavity with Babcock forceps (b). (b): The suture passes through and around the ovarian ligament (l) and ovary (o). (c): The suture is exteriorized through the abdominal wall for manual stimulation. The stimulus is performed with a calibrated force transducer to quantify the tension used. (d): During stimulation, the suture will pull the ovary and ovarian ligament inducing a visceral response. The uterus (u) moves during stimulation but not enough to induce a noxious response.

3. Figure 2
Stimulus – response curve. The stimulus – response curve for sevoflurane MAC when different stimulation forces were applied to the right ovary. The mean ± SD of sevoflurane MAC was measured using the end-tidal sevoflurane concentration. The stimulation force was recorded using a force transducer. # indicates MAC values that were different when compared to 1.96 N. The remaining MAC values were not different between them (p > 0.05).
