- Brief Summary
Surgical procedure including hip joint surgery is extremely painful and associated with considerable postoperative pain in children despite the use of systemic opioids.
Caudal block is a common method used for perioperative pain relief in pediatric lower limb surgeries but carries some complications.
Some novel techniques of regional anesthesia were explored including the quadratus lumborum block (QLB), lumbar plexus block, and recently Pericapsular nerve group (PENG) block.
The objective of the current trial is primarily to assess the analgesic efficacy of ultrasound-guided trans-muscular QLB versus ultrasound-guided PENG block in pediatric patients undergoing open hip surgery for developmental dysplasia of the hip (DDH)
- 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 detailed 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, oxygen saturation (SpO2), temperature probe, and end-tidal CO2 (EtCO2) will be applied to all participants. Induction of anesthesia 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 general anesthesia, the eligible participants will be randomly assigned to one of two equal groups using an allocation sequence which will be generated using permuted block randomization technique and the block size will be variable.
In both interventional groups of participants, the assigned block will be performed after induction of general anesthesia 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 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 patients. Postoperative pain will be assessed by FLACC score (Face, leg, activity, cry, consolability). Morphine 0.1 mg /kg IV will be given as rescue analgesia if the FLACC score will be \> 3. Postoperative HR and MAP will be recorded postoperatively at 2 h, 4, 8, 12, 24, and 48 hours.

Group Intervention Description Pericapsular nerve group (PENG) block PENG block After induction of GA, the participant will be in the supine position. A linear high-frequency ultrasound probe (5-13MHz) 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. 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. Following negative aspiration, the local anesthetic solution of 0.25% bupivacaine will be injected in 5-mL increments while observing for an adequate fluid spread in this plane for a total volume of 0.5 ml/kg. trans muscular quadratus lumborum (TQL) block TQL block after induction of general anesthesia (GA), the participant will be placed in the lateral position, and a high-frequency linear ultrasound probe (5-13 MHz) will be placed on the anterior iliac crest. The Petit's triangle (formed of the iliac crest inferiorly and the borders of external abdominal oblique anteriorly and latissimus dorsi (LD) posteriorly) will be identified and then Tracing dorsally from Petit's triangle, the external oblique, and the internal oblique are seen disappearing into an aponeurosis as the quadratus lumborum (QL) appears beneath the LD (anteriorly), and going farther dorsally, the QL, erector spinae, and psoas major (PM) muscles around the transverse process of lumbar vertebra L4 are seen. A 22-gauge needle will be inserted using an in-plane technique along the posterior edge of the probe in the anteromedial direction. The needle tip will be placed between the QL muscle and the PM muscle, then 0.5 ml/kg of 0.25% bupivacaine will be injected.
- Primary Outcome Measures
Name Time Method the time until the first rescue analgesic requirement postoperatively During the first postoperative 48 hours Postoperative pain will be assessed by Face, leg, activity, cry, consolability (FLACC) score at different time points with a minimum score of zero (relaxed \& comfortable) to a maximum of 10 (severe discomfort \& pain). This will be done by the attending physician either in the PACU or in the ward. If FLACC will come \> 3, morphine 0.1 mg/kg will be given as rescue analgesia
