Table 2 Postoperative complications, n (%)

Postoperative complications	Desflurane group, n = 23	Control group, n = 23	P value
Postoperative blood transfusion (red blood cells)			0.555
0 U	13 (56.5)	11 (47.8)
1 U	10 (43.5)	10 (43.5)
2 U	0	2 (8.7)
Bile leak	2 (8.7)	2 (8.7)	1.00
Deep vein thrombosis	2 (8.7)	1 (4.3)	0.555
Pneumonia	4 (17.4)	5 (21.7)	0.71

Variables are expressed as absolute and relative values (%). Fisher’s exact test was used for comparisons between the two groups.
