Purpose of review: The objective of the current review is to examine the likelihood of improved safety in peripheral nerve blockade attributable to ultrasound guidance.
Recent findings: With ultrasound guidance, a 10-fold reduction in the incidence of local anesthetic systemic toxicity as well as a tendency toward less long-term neuropathies are shown.
Summary: Ultrasound is clearly superior to other techniques with the aim of achieving maximum efficacy with minimum risk: a win-win approach.
