objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

Kilohertz electrical stimulation (KES) has been shown to induce repeatable and reversible nerve conduction block in animal models. In this study, we characterized the ability of KES stimuli to selectively block specific components of stimulated nerve activity using in vivo preparations of the rat sciatic and vagus nerves. KES stimuli in the frequency range of 5-70 kHz and amplitudes of 0.1-3.0 ...

OBJECTIVE Block of the sciatic nerve at the popliteal fossa can be performed using the ultrasound machine; it may be proximally or distally to the bifurcation of the sciatic nerve using lateral, medial, or posterior approaches. It is frequently used for surgeries below the knee specially the foot and ankle operations. PURPOSE This study compares one and two injections of the sciatic nerve in ...

objective(s): to investigate the effect of topical administration of alpha-lipoic acid into chitosan conduit on peripheral nerve regeneration using a rat sciatic nerve transection model. materials and methods: forty five wistar rats were divided into three experimental groups randomly. a 10-mm gap of sciatic nerve was bridged with a chitosan conduit following surgical preparation and anesthesia...

Both obturator and sciatic nerve block in combination with femoral nerve block (FNB) have been suggested to be useful in relieving pain after total knee arthroplasty (TKA), compared with FNB alone. We compared their efficacy in this retrospective study. For six consecutive months, patients undergoing unilateral TKA under general anesthesia with continuous FNB plus obturator nerve block (n = 8) ...

BACKGROUND Sciatic nerve block is widely used for anesthesia and analgesia in lower limb surgery, traditional method used for sciatic nerve block is nerve stimulation guidance. Whether the use of ultrasound-guided technology can increases the success rate of sciatic nerve block and provide other benefits are not defined. This meta-analysis was aimed to clarify this issue. METHOD We searched P...

objective: to assess the effect of heparin binding neurotrophic factor (hbnf) on sciatic nerve regeneration in animal model of rat. methods: seventy-five male wistar rats were divided into five experimental groups randomly (each group containing 15 animals): sham operation group (sham), autograft group (auto), transected control (tc), chitosan conduit (chit) and heparin binding neurotrophic fac...

BACKGROUND Sciatic nerve block when combined with femoral nerve block for total knee arthroplasty may provide superior analgesia but can produce footdrop, which may mask surgically induced peroneal nerve injury. In this prospective, randomized, observer-blinded study, we evaluated whether performing a selective tibial nerve block in the popliteal fossa would avoid complete peroneal motor block....
