Periarterial Injection Versus Multiple Periveural Injection

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

  • Inclusion criteria:
  • Patients (ASA physical status I-III) scheduled to undergo hand or wrist surgery under axillary brachial plexus block
  • Exclusion criteria:
  • Patients with pre-existing neuropathy
  • Patients with allergy to local anesthetics
  • Patients with prior surgery in the ipsilateral axilla
  • Pregnant patients
  • Patients with difficulties in communication

Treatment and study plan

US-guided periarterial techique

Procedure

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

US-guided multi-injection technique

Procedure

The median, ulnar and radial nerves will be identified by ultrasound. Local anesthetic will be injected adjacent to each nerve

Primary outcomes

  1. Block procedure time for the axillary brachial plexus block

    Time frame: time of the block achievement will be recorded up to 15 minutes

Secondary outcomes

  1. Onset of the block

    Time frame: outcome measure will be measured up to 30 minutes a

  2. Time to request pain medication

    Time frame: participants will be followed for 3 days

  3. Block success rate

    Time frame: participants success or block failure within 24 hours
