Study Summary

For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Surgery of the distal upper limb : hand, forearm, lower third of the arm ,includingthe elbow
  • Urgent or planned surgery
  • Locoregional anesthesia : axillary brachial plexus block, completed by a medialbrachial cutaneous nerve block and an intercostobrachial nerve block

Exclusion

Exclusion Criteria:

  • Refused to sign informed consent
  • Pregnant women
  • Allergic to the local anesthetic

Study Description

The primary objective of our study was to compare the effectiveness of conventional and USG blocks of the MBCN and the ICBN in the axillary fossa. Our hypothesis was that the proportion of patients with complete anesthesia in the entire posteromedial and anteromedial surface of the arm would be greater if a USG technique were used, compared with a conventional technique. The secondary objectives were onset time of complete anesthesia, volume of local anesthetic used for the procedure, tourniquet tolerance during surgery, and ultrasound visibility of MBCN and ICBN.
