Figure 1. Recovery of sensation to touch, cold, pinprick, and transcutaneous electric stimulation after tourniquet release is slowest in the high-dose ropivacaine group and is consistently slower than in the lidocaine group. Differences in the recovery of sensation to pinprick and transcutaneous electric stimulation are noted between the high-dose and low-dose ropivacaine groups. Differences in the recovery of touch and cold sensation are found between the low-dose ropivacaine and lidocaine groups.
