Figure 2. Tactile withdrawal threshold (mN) to von Frey monofilament testing after sciatic nerve block with ropivacaine.

Figure 2

This is an illustration of nociceptive responses of the treated (left) hindlimb to tactile stimuli as a function of treatment and time. The last time point (\on the X-axis represents behavioral testing before rats were euthanized (postoperative day 12–14). The ropivacaine (RPV) group showed anesthesia at 1 hr after injection (P<0.001), compared to the vehicle group (VEH). There were no statistically significant differences in tactile withdrawal threshold (mN) to von Frey monofilament testing between the RPV and VEH groups at any other time point.
