Data are presented as mean ± SD, median (interquartile range), or number (percentage); PACU: postoperative care unit; PONV: postoperative nausea and vomiting; PVB: paravertebral block; RIB: rhomboid intercostal nerve block; SAPB: serratus plane block; For within-group comparisons, comparison between RIB and PVB group is no statistical significance between the two groups(P > 0.05); comparison between SAPB and PVB or RIB and SAPB have statistical significance between the two groups(P < 0.05); Multiple comparisons within groups have been adjusted for significance values by Bonferroni correction for multiple tests
