Distal Peripheral Nerve Stimulation Successfully Assesses Sciatic Nerve Integrity Following Parasacral Sciatic Motor Block: A Case Report

Following the placement of lumbar plexus and parasacral sciatic catheters for complex lower extremity surgery, a 19-kg child had dense sensory and motor blockades in the postanesthesia care unit. The surgical team felt obligated to exclude anatomically modifiable compression of the sciatic nerve and planned for surgical reexploration. Using an insulated short, beveled needle, direct electrical nerve stimulation distal to the parasacral sciatic block and proximal to the surgical site elicited tibial nerve motor function and confirmed nerve integrity. Peripheral nerve stimulation can be used to differentiate between the etiologies of motor blockade in time-critical situations.
