简要总结
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.
详细描述
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.
