Overview
The aim of the study is to compare postoperative analgesia in pediatric patients undergoing inguinal hernia repair by comparing the efficacy of ultrasound guided paravertebral block versus ultrasound guided erector spinae plane block.
Description
- To assess the total amount of rescue analgesic consumption in the first 24 hours
post-operatively in each group.
- To measure the time of first request of rescue analgesia and to assess pain intensity at rest (static) and after movement or coughing (dynamic) using 10 points Modified Objective Pain Score (MOPS).
- To record the incidence of complications (hematoma, local anesthetic toxicity, pneumothorax, infection, hypotension, epidural or intrathecal spread).
- Over all parent's satisfaction: The parents will be asked to rate the overall degree of satisfaction of the analgesia by using a 5-points likert-like verbal scale (1 = very dissatisfied analgesia, 2 = dissatisfied analgesia, and 3 = neutral, 4=satisfied analgesia, and 5=very satisfied analgesia).
