VAS scores and number of patients receiving rescue analgesia among the three groups

Time after surgery	Group P2.5 (n=43)	Group P7.5 (n=43)	Group P+D (n=43)	P-value
4 h	2 (1.5)	2 (2)	2 (1)	0.7854
24 h	2 (1)	2 (1)	2 (1)	0.3698
48 h	0 (1)	0 (1)	0 (1)	0.8936
72 h	0 (0)	0 (0)	0 (0)	0.1432
Number of patients receiving rescue analgesia, n (%)	3 (7.0)	3 (7.0)	1 (2.3)	0.6980

Notes: Group P2.5: 2.5 μg/kg palonosetron; Group P7.5: 7.5 μg/kg palonosetron; and Group P+D: 2.5 μg/kg palonosetron and 15 μg/kg droperidol. VAS scores are expressed as median (interquartile range). Dunn’s test was used for post hoc pairwise comparisons.

Abbreviation: VAS, visual analog scale.
