Fig. 5. Application of capsaicin (0.05%) after injection of either (A) 1% or (B) 2% of lidocaine + QX-314 (0.2%) significantly increased the nociceptive blockade produced by lidocaine coinjected only with QX-314 (0.2%). (C) Comparison of the duration of nociceptive (closed diamonds) and motor (open diamonds) blockade produced by triple application of 1% lidocaine/capsaicin/QX-314 (black diamonds) or 2% lidocaine/capsaicin/QX-314 (gray diamonds). Grading for the nociceptive block is as in Fig. 3. Grading for the motor block is as in Fig. 4. (D) Differential block produced after sciatic nerve injection of lidocaine, QX-314, and capsaicin.
