Periarterial Injection Versus Multiple Periveural Injection

August 26, 2016 updated by: Catherine Vanderpitt, MD, North American Institute for Continuing Medical Education (NAICE)

The Ultrasound Guided Periarterial Injection Technique To Axilary Brachial Plexus Block Versus Perineural Multiple InjectionTechnique

In the transarterial technique for axillary brachial plexus block, the axillary artery is intentionally punctured to indicate placement of the needle within the neurovascular sheath; local anesthetic is then injected deep and superficial to the axillary artery.

Detailed Description

To lessen the risk for hematoma and intravascular injection, several modifications, such as the multi-injection perineural technique, have become popular. These techniques require a high degree of technical skill and multiple needle passes, and also carry potential for injury. In this study, the investigators will compare an ultrasound-guided equivalent of the transarterial technique (periarterial injections) to a commonly used multi-injection perineural technique.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: US-guided periarterial techique
Axillary brachial plexus block by an ultrasound-guided periarterial technique
Procedure: US-guided periarterial techique
The needle will be inserted in the axillary fossa in-plane (cranial to caudal) close to the intersection of the pectoralis and biceps muscles. Two separate injections of local anesthetic will be made deep and superficial to the axillary artery
Experimental: US-guided multi-injection technique
Ultrasound-guided multi-injection perineural technique for axillary brachial plexus
Procedure: US-guided multi-injection technique
The median, ulnar and radial nerves will be identified by ultrasound. Local anesthetic will be injected adjacent to each nerve
