Erector Spinae Versus Ilioinguinal/ Ilio-hypogastric Block in Children Undergoing Inguinal Surgeries

Ultrasound Guided Erector Spinae Versus Ilioinguinal/ Ilio-hypogastric Block for Postoperative Analgesia in Children Undergoing Inguinal Surgeries

Investigators aim to compare the efficacy of US-guided II/IH nerve block versus US-guided ES block for pediatric unilateral inguinal hernia repair with respect to postoperative analgesia

regarding patient registry; a prior G power analysis was done. 24 per group was determined to achieve 80% power to detect a difference of 60 min in time to first rescue analgesia between the two groups with a significance level (α) of 0.05 using a two-sided two-sample t-test; 25 patients were included per group to replace any dropouts.

- Statistical analysis: Data will be analyzed through SPSS (Statistical Package for Social Sciences). Program version 22. Distribution of data will be first tested by the Shapiro test. Data will be presented as the mean and standard deviation (SD), median and range or numbers and percentages. For normally distributed data, the unpaired t-test will be used to compare the mean values of both groups. For pain score, Mann Whitney U test will be used. Fisher's exact test will be used for comparison of categorical data. The P value ≤ 0.05 will be considered as the level of statistical significance.
