The comparison of NRS mean in different time between two groups and mean postoperative analgesic consumption in two groups over 24 hours.
| Variables | Magnesium sulfate* | Normal saline* | Mean difference** | P value | ( = 20) | ( = 20) | (95% CI) |
| Pain severity based on (NRS) | Emergence time | 4.30 ± 2.54 | 3.70 ± 0.73 | 0.60 (−0.59, 1.80) | 0.102 | 6 h | 6.45 ± 1.05 | 9.80 ± 0.62 | −3.35 (−3.90, −2.80) | 0.0001 | 12 h | 5.90 ± 0.79 | 7.80 ± 1.11 | −1.90 (−2.51, −1.29) | 0.0001 | 24 h | 4.60 ± 0.94 | 5.90 ± 0.45 | −1.30 (−1.78, −0.82) | 0.0001 | Pethidine consumption (mg) | 16.75 ± 18.23 | 68.0 ± 17.42 | −51.25 (−62.67, −39.83) | 0.0001 |
