INTRAOPERATIVE BLEEDING
A total of 60 patients were initially recruited for the study, with one patient excluded from the PENG group due to the operation duration exceeding 3 h. Ultimately, the statistical analysis included 29 cases in the PENG group. Similarly, one patient was excluded from the FICB group due to lumbar puncture difficulty, and an additional patient withdrew voluntarily, resulting in 28 cases included in the statistical analysis for the FICB group. There were no significant differences in age, gender, BMI, ASA classification, surgical time, and intraoperative bleeding between the two groups (all P > 0.05). The detailed data are shown in Table
