Ultrasound guidance compared with electrical neurostimulation for peripheral nerve block: a systematic review and meta-analysis of randomized controlled trials

Abstract

US improves efficacy of peripheral nerve block compared with techniques that utilize PNS for nerve localization. Larger studies are needed to determine whether or not the use of US can decrease the number of complications such as nerve injury or systemic local anaesthetic toxicity.

Comparison of three techniques for paravertebral brachial plexus blockade in dogs

“…In humans, the use of ultrasound guidance during regional anesthesia has improved the clinical success rates and decreased the complication rates compared to neuro-stimulator guidance (Liu et al 2005;Chan et al 2007;Koscielniak-Nielsen 2008;Abrahams et al 2009). In cadaveric dogs, the US guided technique for PBPB resulted in 100% successful staining of the nerve roots C6, C7 and C8 (Bagshaw et al 2009).…”

“…In humans, introduction of US guidance for RAnT has greatly improved the success rates, shortened performance and onset time, prolonged duration of the block and decreased the incidence of block-related complications, such as inadvertent vascular puncture, compared to other techniques (Liu et al 2005;Chan et al 2007;Koscielniak-Nielsen 2008;Abrahams et al 2009). The use of US allows clear visualization and localization of nerves, provides real-time guidance for needle movement and allows observation of local anesthetic spread around the nerve, enabling a decrease of the total dose of local anesthetic used (Marhofer et al 2005).…”

Ultrasound-guided regional anesthesia for upper limb surgery

“…6 Ultrasound guidance has been shown to increase the likelihood of success, reduce the time to perform the technique, decrease the onset time of the block, and diminish the risk of vascular puncture when compared with nerve stimulation alone. 7 Therefore, in this module, we have elected to discuss ultrasound-guided techniques exclusively.…”

Eficacia analgésica de una dosis única de dexametasona perineural en el bloqueo ecoguiado del nervio femoral en cirugía de prótesis total de rodilla

“…La ecografía aplicada en los bloqueos locorregionales ha demostrado ser una técnica segura y eficaz, mejorando la calidad del bloqueo anestésico-analgésico, comparada con la neuroestimulación 8,9 , permitiendo utilizar volúmenes de anestésicos menores 10 , disminuyendo el tiempo de latencia y prolongando la analgesia 11 .…”
