About this study
Official title: Comparing the Postoperative Analgesic Effect of Fascia Transversalis Plane Block Versus Pericapsular Nerve Group Block for Hip Surgery in Pediatrics: A Randomized Controlled Clinical Trial
Hip joint surgery for developmental dysplasia of the hip (DDH) in children is extremely painful and associated with considerable postoperative pain despite the use of systemic opioids. Caudal anesthesia and lumbar plexus block (LPB) were still the most common regional anesthesia techniques for perioperative analgesia in children undergoing this type of surgery. recently, pediatric anesthesiologists don't consider choosing both techniques because of potential complications such as intravascular and intrathecal injection, and urine retention. novel peripheral nerve blocks have been advocated in pediatrics to avoid the aforementioned complications such as PEricapsular Nerve Group (PENG) block, Quadratus Lumborum Block (QLB), and Fascia Transversalis Plane Block (FTPB) The objective of the current study is to assess the analgesic efficacy of ultrasound-guided FTPB versus ultrasound-guided PENG block in pediatric patients undergoing open hip surgery for DDH
Read the detailed description
During the pre-anesthesia check-up visit, the proposed intervention will be discussed with the eligible participant's parents or caregivers including data about the aim, the advantages, and the expected side effects, and then a detailed written informed consent will be obtained before recruitment and randomization.
All participants will be premedicated with 0.5mg/kg oral midazolam about 30min before being admitted to the operating room. The routine standard monitoring including electrocardiography (ECG), non-invasive blood pressure (NIBP), pulse oximetry for blood oxygen saturation (SpO2), temperature probe, and end-tidal CO2 (EtCO2) will be applied to all participants. Induction of general anesthesia (GA) will be performed using a face mask with sevoflurane inhalation in oxygen starting with 2% up to 8% till complete loss of consciousness after that peripheral intravenous (IV) line will be secured where fentanyl 1 μg/kg and followed by cisatracurium 0.15mg/kg to facilitate orotracheal intubation. Anesthesia will be maintained by using isoflurane 1.2-1.5% in oxygen air mixture 50%:50% in addition to incremental cisatracurium 0.03mg/kg.
After induction of GA, the eligible participants will be randomly assigned to one of two equal groups either FTPB or PENG block.
In both interventional group participants, the assigned block will be performed after induction of GA by the same investigator who will have no further role in the study. Surgery will be started about 15 minutes after performing the block.
Fentanyl 1μg/ kg will be administrated intraoperatively in the case of inadequate analgesia which is defined as an increase of heart rate (HR) and/or mean arterial blood pressure (MAP) more than 20% above the pre-operative values. At the end of the surgery, isoflurane will be switched off and extubation will be done after reversal of muscle relaxant with neostigmine 0.05 mg/kg and atropine 0.02 mg/kg where the participants will be transferred to the Post-Anesthesia Care Unit (PACU). Paracetamol (15 mg/kg) will be administered IV every 6 hours in all participants.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FTPBProcedure or surgery
Also called Fascia Transversalis Plane Block
A 22-gauge needle will be advanced from anterior using an in-plane technique and passed through the posterior 'tail' of the transversus muscle. the local anesthetic solution of 0.25% bupivacaine will be injected for a total volume of 0.5 ml/kg will be injected to separate the transversalis fascia from the transversus muscle.
PENG BlockProcedure or surgery
Also called Pericapsular Nerve Group block
A 22-gauge, 80-mm needle will be inserted from lateral to medial in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly where the local anesthetic solution of 0.25% bupivacaine will be injected for a total volume of 0.5 ml/kg
| Study group | Role | What they receive |
|---|---|---|
| the ultrasound-guided fascia transversalis plane block | Experimental | The TFPB will be performed while the participant is in the supine position. a high-frequency linear ultrasound probe (5-13 MHz) will be placed transversely in the midaxillary line between the iliac crest and the costal margin. After the external oblique, internal oblique, transversus abdominis muscle, and quadratus lumborum (QL) muscle will be identified. Receives: Procedure: FTPB |
| The ultrasound guided Pericapsular Nerve Group block | Experimental | while the participant is in the supine position, a linear ultrasound probe will be initially placed in a transverse plane over the anterior inferior iliac spine (AIIS) and then aligned with the pubic ramus by rotating the probe counterclockwise approximately 45 degrees; In this view, the ilio-pubic eminence (IPE), the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle will be observed. Receives: Procedure: PENG Block |
What is being measured
The primary outcome is the main question the study is designed to answer.
The time until the first rescue analgesic requirement postoperatively
Postoperative pain will be assessed by Face, leg, activity, cry, consolability (FLACC) score by the attending physician either in the PACU or in the surgical ward which ranges from a minimum score of zero (relaxed \& comfortable) to a maximum of 10 (severe discomfort \&pain). Morphine IV 0.1 mg/kg will be given as rescue analgesia if the FLACC score will be more than 3.
Measured: the first postoperative 48 hours

Questions about this trial
What is this clinical trial studying?
A study testing FTPB and PENG Block in people with Pain, Postoperative and Developmental Dysplasia of the Hip, run by Alexandria University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The time until the first rescue analgesic requirement postoperatively (time frame: the first postoperative 48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05348421, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023.
