Erector Spinae Plane Block Versus Quadratus Lumborum Block for Postoperative Analgesia in Children

Study Overview
=================
Brief Summary
-----------------
Postoperative pain management in children is still standing as a problem to solve. Effect of quadratus lumborum block has been shown to be a promising technique to overcome postoperative pain in children undergoing low abdominal surgeries. Erector spinae plane block is a new defined relatively safer and easier regional anesthesia technique which could be used for this purpose. Primary aim of this double blinded randomized controlled trial is to compare the analgesic efficacy of this two block techniques in this group of pediatric patients.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain scores | FLACC scale will be used. The Face, Legs, Activity, Cry, Consolability scale or FLACC scale is a measurement used to assess pain for children between the ages of 2 months and 7 years or individuals that are unable to communicate their pain. The scale is scored in a range of 0-10 with 0 representing no pain. The scale has five criteria, which are each assigned a score of 0, 1 or 2. | Postoperative first 6hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to first analgesic drug | Time to first analgesic drug will be recorded | first 48 hour | 
| Need for analgesic | Number of patients who required analgesic in the first 24 hour | 24 hour |
