Table 4

Postoperative visual analog score at rest.

Time points	Control group (n = 30)	SGB group (n = 30)	value
PACU discharge	2.0 (1.0–3.2)	2.0 (1.0–3.0)	0.885
2 hours postoperatively	2.0 (1.0–3.0)	2.0 (1.0–3.0)	0.867
4 hours postoperatively	1.0 (0–2.0)	2.0 (1.0–2.2)	0.152
8 hours postoperatively	1.0 (0.7–2.0)	1.0 (0–2.0)	0.542
24 hours postoperatively	1.5 (1.0–2.0)	1.0 (0–2.0)	0.346

The variables are presented as median (IQR). SGB, stellate ganglion block; IQR, interquartile range; PACU, postanesthesia care unit.
