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

Table 2 Comparison of Visual Analog Scale scores at different postoperative time points between two groups (points, mean ± SD)

Time point	Resting VAS score			Movement VAS score
	Observation group (n = 59)	Control group (n = 58)	P value	Observation group (n = 59)	Control group (n = 58)	P value
Postop 6 hours	2.1 ± 0.8	3.4 ± 1.1	< 0.001	3.5 ± 1.0	4.9 ± 1.3	< 0.001
Postop 12 hours	1.8 ± 0.7	2.9 ± 0.9	< 0.001	3.1 ± 0.9	4.3 ± 1.1	< 0.001
Postop 24 hours	1.5 ± 0.6	2.4 ± 0.8	< 0.001	2.7 ± 0.8	3.7 ± 1.0	< 0.001
Postop 48 hours	1.2 ± 0.5	1.9 ± 0.7	< 0.001	2.2 ± 0.7	3.1 ± 0.9	< 0.001
Postop 72 hours	1.0 ± 0.4	1.5 ± 0.6	< 0.001	1.8 ± 0.6	2.5 ± 0.8	< 0.001

Bonferroni method was used for multiple comparison correction, with corrected significance level α = 0.01; indicates P < 0.001, remaining statistically significant after correction.
