Values are presented as mean ± standard deviation (range). Data were analysed by the Mann-Whitney U-test or the t-test according to the normality of data to evaluate the differences of the mean values between group 1 and group 2 (p < 0.05).
Group 1: intraoperative suprascapular nerve block (SSNB) was performed under arthroscopic guidance in addition to preemptive SSNB and axillary block, Group 2: preoperative SSNB was performed without guidance, CI: confidence interval.
