Minimum effective local anesthetic volume for surgical anesthesia by subparaneural, ultrasound-guided popliteal sciatic nerve block
Because of its rapid onset time, recent years have seen an increase in the use of ultrasound (US)-guided popliteal sciatic nerve block (PSNB) via subparaneural injection for induction of surgical anesthesia. Moreover, in below-knee surgery, combined blocks, as opposed to sciatic nerve block alone, have become more common. These combined blocks often require a large volume of local anesthetic (L...
متن کاملIntraneural 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 کاملUltrasound guidance improves a continuous popliteal sciatic nerve block when compared with nerve stimulation.
BACKGROUND AND OBJECTIVES Continuous sciatic nerve blockade at the popliteal level effectively alleviates postoperative pain after major foot and ankle surgery. No randomized controlled trials have previously compared the success rate of continuous sciatic nerve sensory blockade between ultrasound and nerve stimulation guidance. In the current study, we tested the hypothesis that ultrasound-gui...
متن کاملLateral popliteal sciatic nerve block compared with subcutaneous infiltration for analgesia following foot surgery.
A new lateral approach to blocking the sciatic nerve in the popliteal fossa is described. In a prospective study, 40 patients scheduled for foot surgery involving osteotomies were allocated randomly into one of two groups following induction of general anaesthesia: group PS (n = 21) received a lateral popliteal sciatic nerve block and group SC (n = 19) received subcutaneous infiltration of the ...
متن کاملIs sickle cell disease a possible risk factor for peripheral neuropathy after popliteal sciatic nerve block?
trauma service of Tuscany. In the population examined, the mortality rate was 11.5%, lower than the 18.9% in the German validating group of the original paper by Raum and colleagues, but EMTRAS calculations were still effective in predicting mortality (AUC 0.802). In our trauma population, EMTRAS lacked the efficacy shown in the German validating group. Our patients were similar to those in the...
