ESPB, erector spinae plane block; TAPB, transversus abdominis plane block; VAS, visual analog scale; PCIA, patient-controlled intravenous analgesia; RSS, Ramsay sedation scale.

The measurement data in normal distribution were described as mean ± SD, and compared using independent sample t-test. The measurement data in non-normal distribution were described as M (Q1, Q3), and compared using rank-sum test. The counting data were described as n (%), and compared using χ² test. The ranking data was shown as n (%), and compared using rank-sum test.
