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...
متن کاملNerve puncture and apparent intraneural injection during ultrasound-guided axillary block does not invariably result in neurologic injury.
BACKGROUND Nerve puncture by the block needle and intraneural injection of local anesthetic are thought to be major risk factors leading to neurologic injury after peripheral nerve blocks. In this study, the author sought to determine the needle-nerve relation and location of the injectate during ultrasound-guided axillary plexus block. METHODS Using ultrasound-guided axillary plexus block (1...
متن کاملThe Effect of Ultrasound on Acceleration of Peripheral Nerve Injury
Background: Many people suffer from nerve injury. The time consuming nature of the treatments makes the condition worse. Therefore, finding a way to accelerate the process of nerve repair is very important.Objective: To determine the effect of ultrasound on the acceleration of crushed peripheral nerve regeneration.Methods: The experimental model included crushed rat’s sciatic nerve. 40 rats w...
متن کاملIntraneural 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 ...
متن کاملPeripheral nerve injury after local anesthetic injection.
BACKGROUND A well-known complication of peripheral nerve block is peripheral nerve injury, whether from the needle or toxicity of the medication used. In this study, we sought to determine the extent of damage that results from intrafascicular injection of various commonly used local anesthetics (LAs). METHODS Sixteen Lewis rats received an intrafascicular injection of saline (control) or 1 o...
