Interventions

  • Ultrasound-Guided Transversus Abdominis Plane Block — PROCEDURE
    Following induction of general anesthesia and before the start of surgery, an ultrasound-guided transversus abdominis plane (TAP) block will be performed. After identification of the target fascial plane and confirmation by hydrodissection, 0.2% bupivacaine will be administered at a volume of 0.5 mL/kg. The total bupivacaine dose will be limited to 2 mg/kg.
  • Ultrasound-Guided Linea Semilunaris Block — PROCEDURE
    Following induction of general anesthesia and before the start of surgery, an ultrasound-guided umbilical paramedian linea semilunaris block will be performed. The linea semilunaris will be identified under ultrasound guidance, and the appropriate fascial plane will be confirmed by hydrodissection. Subsequently, 0.2% bupivacaine will be administered at a volume of 0.5 mL/kg. The total bupivacaine dose will be limited to 2 mg/kg.

Study Details

The aim of this prospective randomized controlled trial is to compare the postoperative analgesic efficacy of ultrasound-guided transversus abdominis plane (TAP) block and umbilical paramedian linea semilunaris block in pediatric patients undergoing elective laparoscopic abdominal surgery. A total of 56 pediatric patients will be randomly assigned in a 1:1 ratio to receive either a TAP block or a linea semilunaris block after induction of general anesthesia and before the start of surgery. Both blocks will be performed under ultrasound guidance using 0.2% bupivacaine at a volume of 0.5 mL/kg, with the total dose limited to 2 mg/kg. The primary outcome will be total opioid consumption during the first 24 hours after surgery. Secondary outcomes will include postoperative pain scores, time to first analgesic requirement, additional analgesic requirements, postoperative nausea and vomiting, and block-related complications.

Arms

  • Active Comparator: USG Guided Transversus Abdominis Plane Block
    Participants randomized to this group will receive an ultrasound-guided transversus abdominis plane (TAP) block after induction of general anesthesia and before the start of surgery. The block will be performed using 0.2% bupivacaine at a volume of 0.5 mL/kg, with the total bupivacaine dose limited to 2 mg/kg.
  • Experimental: USG Guided Linea Semlunaris Block
    Participants randomized to this group will receive an ultrasound-guided umbilical paramedian linea semilunaris block after induction of general anesthesia and before the start of surgery. After identification of the linea semilunaris and confirmation of the target plane by hydrodissection, 0.2% bupivacaine will be administered at a volume of 0.5 mL/kg, with the total bupivacaine dose limited to 2 mg/kg.

Primary Outcome Measure

Total Postoperative Opioid Consumption During the First 24 Hours [ Time Frame: First 24 hours after surgery ]
