Differences in analgesic consumption, VAS, onset, and duration of sensory and motor block of patients in three groups.

Groups	Group L (n = 19)	Group LD (n = 21)	Group LF (n = 18)	P
Onset time of sensory block (min)	1.9 ± 0.51	1.73 ± 0.51	1.72 ± 0.52	0.44
Duration of sensory block (min)	106 ± 18.03	206 ± 25.05	139 ± 22.89	<0.001
Onset time of motor block (min)	2.15 ± 0.6	2 ± 0.53	2 ± 0.43	0.68
Duration of motor block (min)	119 ± 20.84	225 ± 27.35	147 ± 24.62	<0.001
Total analgesic consumption (mg)	40.78 ± 14.93	25 ± 0.00	34.72 ± 12.54	<0.001
VAS (at time of return sensation)	7.42 ± 1.64	5.61 ± 1.28	6.27 ± 1.70	<0.001

L: lidocaine; LD: combined lidocaine/dexamethasone; LF: combined lidocaine/fentanyl; VAS: visual analog scale.
