| Postoperative 6 h | 30 (20–50) | 30 (10–30) | < 0.999 |
| Postoperative 24 h | 30 (10–40) | 30 (17.5–50.0) | < 0.999 |
| Postoperative 48 h | 20 (9–30) | 20 (10–35) | < 0.999 |
| Postoperative 72 h | 10 (2–20) | 17.5 (10–30) | < 0.999 |
| The VAS when coughing | |||
| Postoperative 1 h (at PACU) | 65 (40–80) | 50 (30–80) | < 0.999 |
| Postoperative 6 h | 65 (40–80) | 50 (30–60) | 0.932 |
| Postoperative 24 h | 50 (40–70) | 50 (50–70) | < 0.999 |
| Postoperative 48 h | 50 (40–60) | 50 (30–60) | < 0.999 |
| Postoperative 72 h | 40 (30–60) | 40 (25–50) | < 0.999 |
Values are median (Q1-Q3). IV PCA: Intravenous patient-controlled analgesia, VAS: visual analogue scale. P values < 0.05 are considered statistically significant.
