Outcome Measures
Primary Outcomes (2)
Success rate
the percentage of patients who successfully complete surgery without any additional anesthesia. Will be assessed at the end of the surgery with an expected average time of 2 hours.
2 hours after the block performance
total anesthesia-related time
The total anesthesia-related time is the sum of performance and onset time (see below).
<30 minutes after the block performance
Secondary Outcomes (8)
imaging time
5 minutes
needling time
5 minutes
number of needle passes
5 minutes
Performance time
10 minutes
Onset time
every 5 minutes until 30 minutes after the end of the block performance
- +3 more secondary outcomes
Other Outcomes (2)
paresthesia and numbness
up to 48 hours postoperatively
blood vessel puncture
10 minutes
Study Arms (2)
single injection
ACTIVE COMPARATORAxillary plexus block performed with single injection dorsally to the artery
Double injection
ACTIVE COMPARATORAxillary plexus block performed with 2 injections: one over musculocutaneous nerve the second one dorsally to the artery
Interventions
The needle will be advanced until the tip is positioned just dorsal to the artery and 35ml of (lidocaine 1.5% with epinephrine 5µg/ml) is deposited in this location.
The needle will be initially advanced toward musculocutaneous nerve and 7 ml of LA (lidocaine 1.5% with epinephrine 5µg/ml) is deposited around the nerve. The needle will be then advanced until the tip is positioned just dorsal to the artery and 28 ml of (lidocaine 1.5% with epinephrine 5µg/ml) is deposited in this location.
35 ml of lidocaine 1.5% with epinephrine 5µg/ml will be used to perform the axillary plexus block
Eligibility Criteria
You may qualify if:
- year of age, ASA physical status I-III, BMI 25 to 35 Kg/m2
You may not qualify if:
- non consents patients, any contraindication to brachial plexus anesthesia (local anesthetic allergy, local infection and coagulopathy), preexisting neuropathy, hepatic or renal failure, pregnancy and surgery in the axillary region.
