Intraneural injection during nerve stimulator-guided sciatic nerve block at the popliteal fossa.

BACKGROUND Exact location of the needle tip during nerve stimulation-guided peripheral nerve blocks is unknown. Using high-frequency ultrasound imaging, we tested the hypothesis that intraneural injection is common with nerve stimulator-guided sciatic nerve (SN) block in popliteal fossa. METHODS Forty-two patients scheduled for hallux valgus repair were studied. Sciatic block at the popliteal...

Intraneural injection during anterior approach for sciatic nerve block.

To the Editor:—We read with interest the case report by Sala-Blanch et al. The authors describe an unorthodox but interesting treatment for patients undergoing continuous sciatic nerve block that raises several concerns. In short, using computed tomographic imaging without clear clinical indication, the authors documented that nerve stimulator–guided needle placement during sciatic nerve block ...

No clinical or electrophysiologic evidence of nerve injury after intraneural injection during sciatic popliteal block.

BACKGROUND Intraneural injection during nerve-stimulator-guided sciatic block at the popliteal fossa may be a common occurrence. Although intraneural injections have not resulted in clinically detectable neurologic injury in small studies in human subjects, intraneural injections result in postinjection inflammation in animal models. This study used clinical, imaging, and electrophysiologic mea...

Intraneural injection with low-current stimulation during popliteal sciatic nerve block.

BACKGROUND Prevention of an intraneural injection of a local anesthetic during peripheral nerve blockade is considered important to avoid neurologic injury. However, the needle-nerve relationship during low-current electrical nerve localization is not well understood. METHODS We postulated that intraneural needletip location is common during low-current stimulation popliteal sciatic nerve blo...
