Double-Injection Costoclavicular Block for Brachial Plexus Blocks
What You Need to Know Before You Apply
What is the purpose of this trial?
In 2020, a trial demonstrated that a 2-injection technique constitutes the optimal method for the costoclavicular block.
This study aims to determine the minimum amount of medication required to achieve a successful double-injection costoclavicular nerve.
Block dose assignment will be done using an up-and-down sequential method, called the Biased Coin Design (BCD).
The double-injection technique for US-guided costoclavicular block consists in depositing two thirds of the LA volume in the deep compartment (to anesthetize the posterior and medial cords), and one third of the injectate in the superficial compartment (to anesthetize the lateral cord).
The ED90 will be calculated using isotonic regression with a 95% confidence interval derived by bootstrapping.

What Are the Treatments Tested in This Trial?
Interventions
- Ultrasound-guided double-injection costoclavicular nerve block
Trial Overview
Researchers are comparing two different amounts of numbing medicine used in an ultrasound-guided double-injection nerve block near the collarbone. The goal is to find the lowest effective dose needed for successful anesthesia.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Active Control
This group will be randomized to receive a fixed lower volume than the previously successful block.
Patients randomized to this group will receive the same volume that was successful in the previous recruitment.
