Table 3: Intraoperative and postoperative fentanyl consumption, length of stay in PACU, and time of first request to rescue analgesia in both groups.
| QLB (n = 48) | TAP (n = 50) | P value | |
| Intraoperative fentanyl consumption (μg) | 40 ± 7.07 | 42 ± 10.36 | 0.802 |
| Cumulative postoperative fentanyl consumption (24 h) (μg) | 58.82 ± 11.11 | 62.14 ± 17.50 | 0.527 |
| Time of first request to rescue analgesia (minutes) | 420.58 ± 114.76 | 267.32 ± 62.32 | 0.000 |
Data are expressed as mean ± SD, median (range). P-value < 0.05 was considered statistically significant. QLB: Quadratus lumborum block group, TAP: Transversus abdominis plane block group.
