Opioids for procedural pain in neonates.

Area of Science:

• Neonatal pain management
• Pharmacological interventions in neonates
• Evidence-based pediatrics

Background:

• Neonates frequently undergo painful procedures for medical reasons.
• Opioids (morphine, fentanyl, remifentanil) are commonly used for neonatal pain but may impact brain development.
• Alternative pain management strategies include non-pharmacological interventions and other drugs.

Purpose of the Study:

• To assess the benefits and harms of opioid use in neonates for procedural pain.
• To compare opioids against placebo, non-pharmacological methods, other analgesics/sedatives, or different opioid administration routes.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) using Cochrane search methods.
• Included preterm and term infants (up to 46 weeks PMA) exposed to procedural pain.
• Primary outcomes: pain assessment using validated scales and adverse events; GRADE methodology used for evidence certainty.

Main Results:

• Opioids probably reduce pain scores (PIPP/PIPP-R, NIPS) during procedures compared to placebo (moderate to low-certainty evidence).
• Evidence is very uncertain regarding pain scores at different time points and for specific harms like bradycardia or hypotension.
• Opioids may increase apnea episodes (low-certainty evidence); no studies reported parent satisfaction or compared different opioid types/routes.

Conclusions:

• Opioids likely offer pain relief during procedures in neonates compared to placebo.
• Significant uncertainty exists regarding opioid-induced harms and effectiveness against non-pharmacological interventions or other analgesics.
• Further research is needed, particularly comparing different opioids and administration routes, and reporting on adverse events.
