Role of transversus abdominis plane block combined with multimodal analgesia in early recovery after radical colorectal cancer surgery

Figure 1 Comparison of postoperative Visual Analog Scale pain scores between observation and control groups at different time points. A: Postoperative Visual Analog Scale (VAS) pain scores in observation groups; B: Postoperative VAS pain scores in control groups. The graph illustrates VAS pain scores at 6, 12, 24, 48, and 72 hours postoperatively. The blue line represents the observation group (TAP block combined with multimodal analgesia), while the red line represents the control group (multimodal analgesia alone). Data are presented as mean ± SD. The observation group demonstrated consistently lower VAS scores compared to the control group across all time points, with both groups showing a declining trend in pain intensity over time. VAS: Visual Analog Scale; TAP: Transversus abdominis plane.
