Comparison of maternal pain scores and labor durations between the two groups.
| Indicator (measurement time/unit) | Combined group (n = 60) | Control group (n = 60) | t value | P value |
|---|---|---|---|---|
| Maternal pain score (VAS, 0–10) | ||||
| VAS before analgesia (mean ± SD) | 7.5 ± 1.1 | 7.6 ± 1.0 | −0.521 | 0.603 |
| VAS at 30 min after analgesia (mean ± SD) | 3.1 ± 0.9 | 7.0 ± 1.0 | −22.454 | <0.001 |
| VAS during active labor (≥6 cm cervical dilation, mean ± SD) | 3.5 ± 1.0 | 6.8 ± 1.1 | −17.195 | <0.001 |
| VAS at 2 h after delivery (mean ± SD) | 2.8 ± 0.8 | 6.5 ± 1.0 | −22.380 | <0.001 |
| Labor duration (min) | ||||
| First stage of labor (mean ± SD) | 330 ± 100 | 370 ± 105 | −2.137 | 0.035 |
| Second stage of labor (mean ± SD) | 80 ± 30 | 98 ± 35 | −3.025 | 0.003 |
| Total labor duration (mean ± SD) | 420 ± 110 | 480 ± 125 | −2.791 | 0.006 |
