Visual Analog Pain Score Assessment and Side Effects for the First 24 Hours After Cesarean Delivery
| Visual analog pain score (0–100 mm)a | 150 mcg PF-morphine + placebo (control group, n = 30) | 300 mcg PF-morphine + acetaminophen (intervention group, n = 30) | P value |
|---|---|---|---|
| Movement at 24 hours,b mean ± SD (mm) | 46 ± 25 | 31 ± 17 | 0.009 |
| Resting at 24 hours, median [IQR] (mm) | 19 (0–33) | 4 (0–10) | 0.011 |
| Average over 24 hours, mean ± SD (mm) | 37 ± 19 | 23 ± 14 | 0.002 |
| Worst over 24 hours, median [IQR] (mm) | 69 (49–77) | 62 (42–70) | 0.15 |
| Side effects | |||
| Percentage of pruritus requiring treatment | Overall: 50% | Overall: 70% | 0.11 |
| Postanesthesia care unit: 33% | Postanesthesia care unit: 47% | 0.35 | |
| Postpartum unit: 40% | Postpartum unit: 57% | 0.17 | |

Mean ± SD were used for normally distributed variables; median (interquartile range) were used for data that were not normally distributed or for data with outliers or ordinal data; and number (percentage) were used for categorical data.
IQR = interquartile range.
a
Visual analog scale of pain using a 100 mm unmarked line.
b
Primary outcome; data are expressed as mean ± SD or median (interquartile range).
