Official title
Comparison of Ultrasound-Guided vs. Conventional Scalp Block for Postoperative Analgesia in Pediatric Supratentorial Tumor Surgeries: A Randomized Controlled Trial.
Overview
Although scalp nerve blocks have been shown to provide effective postoperative analgesia in pediatric neurosurgical procedures, limited data exist on their use under ultrasound guidance. The smaller anatomical structures and higher vascularity of the pediatric scalp increase the risk of inadvertent vessel puncture or systemic toxicity with landmark-based techniques. Ultrasound guidance enables direct visualization of the targeted nerves and adjacent vessels, potentially improving block accuracy and safety. To date, no randomized controlled trial has compared ultrasound-guided versus conventional scalp block specifically in pediatric supratentorial tumor surgeries. This study aims to fill this gap.
Interventions
- Procedure Ultrasound-guided scalp block
Patients will receive ultrasound-guided scalp block using bupivacaine 0.25% at 0.1-0.2 mL/kg per nerve site, not exceeding a total dose of 2.5 mg/kg. - Procedure conventional scalp block
Patients will receive conventional scalp block using landmark-based technique with bupivacaine 0.25% at 0.1-0.2 mL/kg per nerve site, not exceeding a total dose of 2.5 mg/kg.
Primary outcome measures
- Mean arterial blood pressure intraoperatively from baseline till skin incision [Time frame: from 5 minutes immediately before skin incision till the peak mean arterial blood pressure recorded within the first minute after incision]
Secondary outcome measures (4)
- Duration of analgesia [Time frame: 24 hours postoperatively]
- objective pain scale [Time frame: 2, 4, 6, 8, 12, 16, and 24 hours postoperatively]
- Total doses of ketorolac [Time frame: 24 hours postoperatively]
- 6. Total dose of paracetamol [Time frame: 24 hours postoperatively]
