Opioid Selection and Management in Pediatric Patients

Age-Specific Opioid Recommendations

For infants under 2 years old, intravenous nalbuphine is the preferred opioid for rescue analgesia, while intravenous fentanyl is recommended for breakthrough pain in acute settings 1, 2
For children 2-18 years old, oral/rectal/intravenous tramadol is the first-line opioid for ward-based pain management, with fentanyl reserved for acute breakthrough pain 1, 2, 3
Intravenous fentanyl is the primary opioid for treating serious breakthrough pain in the post-anesthesia care unit for infants under 2 years old 1, 2, 3
Fentanyl should be administered in divided doses and titrated to effect for infants under 2 years old 4, 5
Intravenous nalbuphine is specifically recommended as the rescue opioid for infants under 2 years old 1, 2
The American Academy of Pediatrics recommends against codeine use in children under 12 years old due to the risk of respiratory depression 7

The European Society for Paediatric Anaesthesiology emphasizes that opioids should be part of a multimodal strategy, not monotherapy, to minimize opioid use in pediatric patients 4, 5
A non-opioid foundation with NSAIDs and paracetamol can provide opioid-sparing effects in pediatric patients 1, 2, 6
Regional anesthesia with long-acting local anesthetics should be prioritized whenever possible to reduce opioid requirements in pediatric patients 1, 2
Intraoperative ketamine has opioid-sparing effects and reduces respiratory impairment risk in pediatric patients 4, 5
Alpha-2 agonists, such as clonidine, can reduce opioid requirements and postoperative agitation in pediatric patients 4, 5

All opioid administration in pediatric patients requires minimum monitoring with pulse oximetry and clinical observation, and preferably in a high to intermediate care setting for 24-48 hours after major operations 4, 3
Experienced staff should be available around the clock, ideally an Acute Pain Service team, when administering opioids to pediatric patients 4, 5

Codeine should not be used in pediatric patients due to the risk of respiratory depression, even if previously used without apparent adverse effects 7
Opioids should not be relied upon alone for pain management in pediatric patients; a multimodal approach with NSAIDs, paracetamol, and regional anesthesia is recommended to reduce opioid requirements and associated complications 4, 5
PONV prophylaxis is highly recommended when administering opioids to pediatric patients to reduce the risk of postoperative nausea and vomiting 4, 5
Remifentanil should not be used without transition planning to prevent an analgesic gap in pediatric patients 4, 5, 3
