Comparison of ultrasound-guided erector spinae plane block with ultrasound-guided pericapsular nerve group block for paediatric hip surgery: A randomised, double-blinded study

Abstract

Background and Aims: Postoperative pain after hip surgeries in children could be classified as severe, requiring combined intra- and postoperative opioid analgesia with regional blocks. This study was carried out to investigate ultrasound-guided pericapsular nerve group (PENG) block versus ultrasound-guided erector spinae plane (ESP) block for pain management after paediatric hip surgery. The primary objective was to assess the time of the first request for morphine rescue analgesia. Methods: In this randomised study, 56 children scheduled for elective unilateral hip surgery were distributed randomly to ESP and PENG groups. Intraoperative haemodynamics, fentanyl consumption, postoperative pain measurement, morphine consumption, time of first rescue analgesia, adverse effects and parents’ satisfaction score were studied. The primary outcome was the time of the first request for morphine rescue analgesia. The Chi-square test, Student’s t-test and the Mann–Whitney U test were used, where applicable, to compare the groups. Results: The time to first rescue analgesia was significantly longer in Group ESP than in Group PENG (P 0.05). Conclusion: ESP and PENG could be both effective for intraoperative and postoperative analgesia in paediatric hip surgeries, but the ESP block prolonged the time of first rescue analgesia more than the PENG block.
