Reduced Opioid Consumption with Pericapsular Nerve Group Block for Hip Surgery: A Randomized, Double-Blind, Placebo-Controlled Trial

Table 2

Comparison in intravenous fentanyl equivalent consumption (μg) during the first postoperative 24 hrs. Values are presented as mean ± standard deviation.

Variable	PENG (n = 25)	Control (n = 25)
Mean (95% CI)	440.72 ± 242.20	611.07 ± 313.89
Min	177	222.5
First quartile	309.6	423.7
Median	435	594
Third quartile	467	705.5
Max	1482.5	1807.3

A statistically significant difference. values were derived by the independent t-test. The Shapiro–Wilk test was employed to test the normality assumption. PENG, pericapsular nerve group; control, control group.
