Table 2 First 24 h demand of postoperative controlled analgesia (PCA)

Type of patients	No. of patients	No. of demands attempts: mean ± SD	p value
Lidocaine group	25	74.24 ± 40.882	0.235
Fentanyl group	25	61.00 ± 36.860
Type of patients	No. of patients	No. of PCA doses given: mean ± SD	p value
Lidocaine group	25	36.76 ± 14.895	0.954
Fentanyl group	25	36.52 ± 14.336	0.954

PCA fentanyl – 1 ml (10 μg) per dose with lockout 10 min provided adequate analgesia in both groups in the first 24 h postoperative: the pain intensity at rest was not different between groups, with a median pain intensity score not exceeding 1 of 10 (p value 0.235), there was no significant difference between the two groups regarding the PCA demands and the PCA doses given to the two groups, fentanyl group required average of 61 ± 36.8 attempts with 36.52 ± 14.336 PCA doses supplied in comparison to the lidocaine group which required 74.24 ± 40.88 PCA doses and supplied by 36.67 ± 14.895 PCA doses with p value of 0.954
