Dual Endpoint Nerve Stimulation Versus Ultrasound in Infraclavicular Block for Hand Surgery

Current best practice for performance of infraclavicular block dictates the use of a dual-endpoint nerve stimulation technique that still only results in a 79% success rate. Use of an ultrasound-guided technique has the potential to significantly improve success. A randomized, controlled study to evaluate this area remains to be performed and is required to demonstrate to anesthesiologists that an ultrasound-guided approach should supersede nerve stimulation as the technique of choice for infraclavicular block.

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

Inclusion criteria

Patients undergoing elective upper limb surgery at or below the elbow.
Patients aged >18 and <80 years
ASA I-III
BMI<35

Exclusion criteria

Inability to read, write or speak English. (This is necessary because subjects will have to follow detailed instructions to allow testing of motor and sensory function. It is not feasible to have an interpreter present in the block room during performance of these procedures)
Contraindication to brachial plexus block
Existing neurological deficit in the area to be blocked
Known loco-regional malignancy or infection
Coagulopathy
Allergy to local anesthetic agents.
Chest or shoulder deformities
Severe respiratory disease
Healed but dislocated clavicle fracture

Treatment and study plan

Ultrasound Guided Infraclavicular Nerve Block

Procedure

Use of Ultrasound to help guide needle placement and local anesthetic injection during infraclavicular nerve block.

Dual-Endpoint nerve stimulation

Procedure

Use of dual-endpoint nerve stimulation to guide needle placement and local anesthetic injection during infraclavicular nerve block.

Primary outcomes

To compare ultrasound-guided infraclavicular block with conventional dual-endpoint nerve stimulator guided infraclavicular block with regards to block success, ease of nerve localization, speed of onset, duration of block and complications.
