Effectiveness Of Intravenous Vs Rectal Acetaminophen For Pain Management In Post Operative Neonates

This randomized controlled trial investigates the comparative effectiveness of intravenous (IV) versus rectal administration of acetaminophen for managing postoperative pain in neonates. Neonates, due to their limited physiological reserves and underdeveloped metabolic systems, require precise pain management strategies to prevent potential developmental delays or adverse effects. Acetaminophen, a commonly used analgesic in neonatal care, is metabolized primarily by the liver and excreted via the kidneys. However, its pharmacokinetics vary significantly based on the route of administration, making it important to evaluate which method offers more reliable pain relief. The study includes 64 term neonates who underwent surgery and are expected to require pain relief for at least 12 hours. Preterm and preoperative neonates are excluded. The neonates were randomized into two groups: one receiving acetaminophen intravenously (15 mg/kg) and the other rectally (40 mg/kg), ensuring similar concentrations at the effect site. Key variables include rescue analgesia requirements, time to rescue analgesia, and changes in pain scores. Pain relief efficacy is measured by pain score changes, and any need for additional analgesia is recorded. This study will provide valuable insights into the optimal route for administering acetaminophen in neonates.
