Prospective Study, monocentric, controlled, randomized study. Evaluating the effectiveness of dermal analgesia provided by the application of Lidocaine and Prilocaine Cream 5% on the puncture site of axillary blocks.Our study includes 70 patients. Number of subjects required for a 50% difference with the standard deviation of the control group, a significance level of 5% for a 80% power, it takes 23 people per group. Objective power of 90% obtained with 35 patients per group.

The expected benefit is the reduction of pain at the skin puncture during the realization of BAX.

Improving professional practice and quality care

Further study details as provided by Poitiers University Hospital:

Primary Outcome Measures:
  • Compare the VAS groups of Lidocaine-Prilocaine 5% and Dexeryl ®
    The main objective of the study is to compare the VAS (visual analogue scale) between groups of Lidocaine-Prilocaine 5% and Dexeryl ® in pain at the skin puncture for producing a block in patients undergoing axillary to an upper extremity surgery

Secondary Outcome Measures:
  • evaluation pain
    - Pain during injection of mepivacaine, measured by a visual analog scale (VAS) from 0 to 100 mm,

  • satisfaction
    - Assessment of satisfaction of anesthetists

  • success
    The success rate of the block defined by the absence of recourse to another anesthetic technique for inadequate analgesia (the use of hypnotic anxiolytic
