Effects of early activity intervention on intestinal motility recovery in patients after colorectal cancer surgery

Table 2 Comparison of postoperative pain scores and related indicators between experimental and control groups, n (%)/mean ± SD

Indicator	Experimental group (n = 40)	Control group (n = 40)	Statistic	P value
NRS pain score (points)
24 hours after surgery	4.2 ± 0.9	5.1 ± 1.2	t = 3.976	0.002
48 hours after surgery	3.0 ± 0.7	4.3 ± 1.0	t = 7.126	< 0.001
72 hours after surgery	1.8 ± 0.5	3.2 ± 0.8	t = 9.542	< 0.001
Good pain control
Proportion with good pain control at 48 hours after surgery1 (%)	33 (82.5)	18 (45.0)	χ2 = 11.882	< 0.001
Analgesic medication use
Additional requests for analgesic medication (times)	2.3 ± 1.1	4.8 ± 1.6	t = 8.475	< 0.001
Pain-related effects
Incidence of pain-related sleep disturbance (%)	6 (15.0)	15 (37.5)	χ2 = 5.227	0.022
Impact of pain on daily activities score (points)	2.6 ± 0.7	4.1 ± 1.2	t = 7.138	< 0.001
Pain control satisfaction rate (%)	36 (90.0)	27 (67.5)	χ2 = 6.465	0.011

¹Good pain control is defined as NRS score ≤ 3 points.

Measurement data were analyzed using t-test, and count data were analyzed using χ² test. P < 0.05 was considered statistically significant.
