Impact of the Pericapsular Nerve Group (Peng) Block on Postoperative Analgesia in Pediatric Hip and Knee Surgery: Case Reports (2 Cases)

Abstract

The Pericapsular Nerve Group (PENG) block is a novel regional anaesthesia technique that aims to provide hipanalgesia with preservation of motor function, although evidence is currently lacking. A PENG (Pericapsular Nerves Group) blockade is effective in both adult and pediatric patients. However, no studies on patients under five are available in the literature. Herein, we describe our experience with two pediatric patients with hip dysplasia and spina bifida. Purpose: This study aimed to evaluate the analgesic effect of the Pericapsular Nerves Group (PENG) in preschool children undergoing hip surgery and spina bifida. Patients and methods: This study included two patients, aged 4 and 2 years old, who were qualified for hip surgery and spina bifida. general anesthesia with the addition of a PENG block was performed. Postoperative pain management after surgery for developmental dysplasia of the hip is a challenge for older children and pediatric patients with epidural block contraindications. Pericapsular Nerve Group (PENG) block is an innovative technique reported for pain control around the hip joint. We report the application of a PENG block in a child with spina malformation who underwent open hip surgery.
