Study summary

This randomized controlled trial (RCT) compares the analgesic effectiveness of two regional anesthesia techniques-Pericapsular Nerve Group (PENG) block combined with Lateral Femoral Cutaneous Nerve Block (LFCB) versus Lumbar and Sacral Erector Spinae Plane Blocks (L-ESPB and S-ESPB)-in pediatric patients undergoing hip surgery.

Read the detailed description

Orthopedic hip procedures in pediatric patients, including osteotomies, arthroscopic interventions, and reconstructive surgeries, often result in significant postoperative pain. Effective analgesia is critical for reducing surgical stress, accelerating rehabilitation, and minimizing opioid use and associated side effects. Regional anesthesia techniques have gained attention for their opioid-sparing effects and enhanced recovery profiles.

This randomized controlled trial aims to compare the analgesic effectiveness of two regional anesthetic approaches:

- The pericapsular nerve group (PENG) block is combined with the lateral fetal cutaneous nerve block (LFCB), targeting hip joint innervation directly and providing comprehensive sensory coverage.

Lumbar and sacral erector spinae plane blocks (L-ESPB and S-ESPB) employ fascial plane techniques to deliver analgesia by diffusing local anesthetic around nerves innervating the hip region.

This trial aims to establish the optimal regional anesthesia technique and determine the clinical benefits of using dexamethasone and dexmedetomidine as adjuvants. The results will guide clinicians toward evidence-based analgesic protocols in pediatric orthopedic hip surgery, potentially reducing opioid-related complications and improving patient recovery outcomes.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Pediatric patients aged between 2 and 16 years.
  • Scheduled for elective orthopedic hip surgery, including: Osteotomies and Hip reconstruction surgeries
  • ASA () physical status classification: I-III.
  • Written obtained from the patient's legal guardian(s).

Exclusion criteria

Exclusion Criteria:

  • Known allergy or to any of the study medications
  • Presence of infection or inflammation at the intended injection site(s) of regional anesthesia.
  • Coagulopathy or bleeding disorders (including patients on anticoagulant therapy) that contraindicate nerve blocks.
  • Neurological disorders or peripheral neuropathies that could influence sensory or motor assessment of the lower limbs.
  • Cognitive impairment or behavioral disorders significantly affecting pain assessment accuracy or cooperation.
  • History of chronic opioid use or known substance abuse.
  • Severe systemic disease or condition compromising patient safety or interfering with study protocol adherence.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
