Abstract: Objective

·To investigate the analgesic effect of ultrasound-guided intercostobrachial nerve (ICBN) block on patients with distal humeral fracture who need surgical treatment through posterior approach.


·One hundred and forty-nine patients with distal humeral fracture were enrolled in Shanghai Sixth People's Hospital from February 2016 to March 2021. They underwent elective surgery via posterior approach under non-general anesthesia and were selected for retrospective analysis. They were divided into two groups according to the way of nerve block: 107 cases of brachial plexus block (BP group), and 42 cases of brachial plexus combined with ICBN block (ICB group). The ICB group was divided into two subgroups according to different approaches of ICBN block: 17 cases in “under pectoralis minor” group (ICB1 group) and 25 cases in “axillary region” group (ICB2 group). The general condition of the four groups, the intraoperative sufentanil dosage, visual analogue scale (VAS) pain score, sedation rate and other analgesic demand rates were analyzed.


·There was no significant difference in age, sex, ASA classification, BMI, operation time and bleeding volume between the BP group and ICB group (P>0.05). There was also no significant difference in these general features between the ICB1 group and ICB2 group (P>0.05). The usage of sufentanil, VAS score, sedation rate and other analgesic drug demand rates in the ICB group were lower than those in the BP group (P=0.001, P=0.000, P=0.012, P=0.018), which was statistically significant. There was no significant difference in aspects mentioned above between the two subgroups (P>0.05).


·Compared with brachial plexus block alone, ICBN block combined with brachial plexus block can significantly enhance the analgesic effect in the operation of distal humeral fracture through posterior approach, and the analgesic effect of the two ICBN block techniques is similar.
