Ultrasound guidance for peripheral nerve blockade

Abstract

In experienced hands, ultrasound provides at least as good success rates as other methods of peripheral nerve location. Individual studies have demonstrated that ultrasound may reduce complication rates and improve quality, performance time, and time to onset of blocks. Due to wide variations in study outcomes we chose not to combine the studies in our analysis.

Precision and Safety of Ultrasound-Guided versus Palpation-Guided Needle Placement on the Patellar Tendon: A Cadaveric Study

“…Nevertheless, we also observed that to achieve this accuracy and safety, ultrasoundguided procedure required significantly more time and more needle passes than the palpation-guided procedure. Contrary to our results, previous studies found that ultrasound guidance can reduce the time of the procedure [25,29,38] and the number of passes [39]. These differences may be due to the fact that the technique evaluated in the current study, unlike previous studies, is a target-contact task, which requires a longer time to achieve a larger and accurate contact surface and, therefore, needs higher precision.…”

“…Our study results demonstrated a significant reduction in the distance between the needle and the targeted tissue, e.g., interface between patellar tendon and Hoffa's fat pad, when employing ultrasound guidance. This finding supports the notion of precise needle tip placement, as previously suggested [23][24][25]. Previous studies with different ultrasound guidance procedures have obtained accuracy rates between 1.5 mm and 3.27 mm when using phantoms [28,36,37].…”

Precision of Ultrasound-Guided versus Anatomical Palpation-Guided Needle Placement of the Ulnar Nerve at the Cubital Tunnel: A Cadaveric Study

“…In this study, an ultrasound-guided procedure significantly decreased the distance from the needle to the targeted tissue supporting an accurate placement of the tip of the needle. Consistent with our results, ultrasound-guided procedures have consistently been demonstrated to improve accuracy for other peripheral nerves [18,26,28]. In fact, previous studies using different systems of ultrasound-guidance with achieved accuracy rates between 1.50-3.27 mm with different phantoms [19,29,30].…”

Ultrasound-Guided Radiofrequency Treatment of Intercostal Nerves for the Prevention of Incidental Pain Arising Due to Rib Metastasis

“…The use of USG guidance provides increased safety during intercostal nerve block by correct needle placement, decreased complication, and decreased time of the proceedure. 40,41 In our study, steroids were used in all patients to decrease the neuritis that may occur after the RF treatment and may be a contributing factor to the pain relief as suggested by Shankar et al 35…”
