Primary endpoint
ESPB
There was no significant difference in postoperative 24-h sufentanil consumption between the ESPB and SAPB groups (adjusted difference, 1.53 [95% CI, -5.15 to 2.08]). However, both the ESPB and SAPB groups showed a significant decrease in postoperative 24-h sufentanil consumption compared to the control group. The adjusted differences were -9.97 [95% CI, -13.10 to -6.84] for the ESPB group and -12.55 [95% CI, -15.63 to -9.47] for the SAPB group (Fig. Sufentanil consumption at 24 h postoperatively among the three groups.
