Wavelet and pain rating index for inhalation anesthesia: A randomized controlled trial

Table 6 Intraoperative/postoperative adverse events and postoperative visual analog scale for pain

	SBP group, n = 21	WLi group, n = 21	PRi group, n = 20	P value
PONV	4 (0.19)	2 (0.10)	3 (0.16)	0.684
Agitation	3 (0.14)	0 (0)	2 (0.10)	0.224
Respiratory depression	0 (0)	0 (0)	0 (0)	1
Intraoperative awareness	0 (0)	0 (0)	0 (0)	1
Pain VAS0h	0 (0-2)	0 (0-2)	0 (0-2)	0.766
Pain VAS1/2h	2 (0-4)	3 (0-4)	2 (0-4)	0.122

Data for adverse events are presented as n (number per patient). Data for visual analog scale for pain are presented as median (range). The visual analog scale for pain ranged from 0 to 10, with 0 representing no pain and 10 representing maximum intensity of pain. PONV: Postoperative nausea and vomiting; PRi: Pain rating index; SBP: Systolic blood pressure; VAS: Visual analog scale; WLi: Wavelet index.
