Brief 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.

Conditions

Nerve Block

Keywords

Ultrasound-Guided Plane Block; Conventional Block

Outcome Measures

Primary Outcomes (1)

• Number of participants with complete anesthesia

  Number of participants with complete anesthesia of the arm in region innervated by the MBCN and the ICBN

  At time 20 minutes after the medial brachial cutaneous nerve and the intercostobrachial nerve block

Secondary Outcomes (6)

• Number of participants with complete anesthesia, with reduced sensitivity and with absence of anesthesia

  At times 5, 10, 15, 20 minutes after the achievement of the medial brachial cutaneous nerve block and the intercostobrachial nerve block

• Volume of local anesthetic

  After nerve block immediately

• Tourniquet tolerance

  3 hours after the achievement of the medial brachial cutaneous nerve block and the intercostobrachial nerve block

• Good ultrasound view of theses nerves before and after the injection of the local anesthetic

  5 minutes after the achievement of the medial brachial cutaneous nerve block and the intercostobrachial nerve block

• Bad ultrasound view of theses nerves before the injection and good ultrasound view of theses nerves after the injection of the local anesthetic

  5 minutes after the achievement of the medial brachial cutaneous nerve block and the intercostobrachial nerve block
