U.S., Jan. 30 -- ClinicalTrials.gov registry received information related to the study (NCT07374952) titled 'Minimal Effective Volume 90% for Double-injection Costoclavicular Block' on Jan. 21.

Brief Summary: 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 posteri...
