Pericapsular Nerve Group (PENG) Block for Congenital Hip Dislocation Surgery

Study Overview
=================
Brief Summary
-----------------
Developmental dysplasia of the hip (DDH) is one of the major disorder of the pediatric population with an incidence of 3 to 5 per 1000 children. Open surgical reduction of congenital hip dislocation (CHD) is typically performed after an ineffective closed reduction or older than 18 months. Multiple femoral or pelvic osteotomies and tenotomies are performed during this surgical treatment and cause severe postoperative pain. Pericapsular nerve group (PENG) block has been recently recommended for use as postoperative analgesia in hip surgeries. It is a new regional anesthesia method based on blocking the articular branches of femoral nerve (FN) and accessory obturator nerve (AON) in the region between the anterior inferior iliac spine (AIIS) and iliopubic eminence (IPE).The aim of this study was to evaluate the analgesic effect of ultrasound guided pediatric pericapsular nerve group (PENG) block in pediatric patients undergoing CHD surgery.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Face, Legs, Activity, Cry and Consolability Score (FLACC) | 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 24hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Need for rescue analgesic | Number of patients who required rescue analgesia in postoperative care unit in the first 2 hour | 2 hour | 
| Need for analgesic | Number of patients who required analgesic in the first 24 hour | 24 hour |
