Brachial plexus blockade is the cornerstone of the peripheral nerve regional anesthesia
practice of most anesthesiologists. As part of the American Society of Regional Anesthesia …

Background Peripheral nerve blocks can be performed using ultrasound guidance. It is not
yet clear whether this method of nerve location has benefits over other existing methods …

Ultrasound guidance improves success rate of axillary brachial plexus block Page 1 176

IMPLICATIONS: Preliminary data, although limited, suggest that ultrasound-guided imaging
during regional blockade may improve outcomes and decrease complications. Educational …

HIGH-RESOLUTION ultrasound can provide direct realtime imaging of peripheral nerves
and identify tissue planes that permit favorable local anesthetic distribution for conduction …

Background: This prospective, randomized, blinded study tested the hypothesis that
ultrasound guidance can shorten the onset time of axillary brachial plexus block as …

Background We tested the hypothesis that ultrasound guidance may reduce the minimum
effective anaesthetic volume (MEAV50) of ropivacaine 0.5% required to block the femoral …

Introduction: Supraclavicular brachial plexus block provides consistently effective
anesthesia to the upper extremity. However, traditional nerve localization techniques may be …

Background: A stimulation current of no more than 0.5 mA is regarded as safe in avoiding
nerve injury and delivering adequate stimulus to provoke a motor response. However, there …

Background and objectives Ultrasound visibility of regional block needles is a critical
component for safety and success of regional anesthetic procedures. The aim of the study …
