Table 2 Comparison of study parameters between the two groups

Study parameters	Group-S (N:40)	Group-I (N:40)	P value
USG scan time (s)	126.75 ± 33.59	102.38 ± 22.22	0.001^*
Block performance time (min)	7.6 ± 1.44	8.1 ± 1.39	0.10
Time for onset of surgical anesthesia (min)	14.48 ± 1.78	17.05 ± 2.28	0.001^*
Number of patients having inadequate block%	3/40 (7.5%)	0/40 (0%)	0.03^*
Number of patients having tourniquet pain (%)	0/40 (0%)	2/40 (5%)	0.15
Number of patients requiring sedation for intraoperative comfort (%)	7/40 (17.5%)	8/40 (20%)	0.99
Number of patients requiring rescue analgesia at the end of 24 h (%)	30/40 (75%)	24/40 (60%)	0.15
Mean time to rescue analgesia (min)	262.2 ± 23.1	288 ± 28.9	0.001^*

USG scan time, block performance time, time to surgical anesthesia, and mean time to rescue analgesia is presented as mean ± SD, comparison done using independent sample Student’s t test. Number of patients having inadequate block, tourniquet pain, requiring sedation were compared using Fisher’s exact test, patients requiring rescue analgesia was compared using chi-square test. ^*indicates P value is significant
