Long-term subcutaneous morphine administration after surgery in newborns

Area of Science:

• Neonatal surgery
• Pediatric pain management
• Pharmacology

Background:

• Effective pain management is crucial for neonates undergoing major surgery.
• Intravenous morphine is a common but invasive method for postoperative pain control in newborns.
• Alternative, less invasive methods are needed to manage neonatal pain.

Purpose of the Study:

• To evaluate the efficacy and safety of subcutaneous morphine administration in neonates after major surgery.
• To identify potential side effects associated with subcutaneous morphine use in this population.

Main Methods:

• Morphine was administered subcutaneously using an Insuflon catheter in 20 neonates post-major surgery.
• Pain was assessed using the Neonatal Infant Pain Score (NIPS) and withdrawal using the Finnegan score.
• Potential side effects including hypotension, administration pain, and infection were monitored.

Main Results:

• All 20 neonates experienced effective pain relief with subcutaneous morphine.
• No severe side effects were observed; three neonates showed transient crying upon initial administration.
• The Insuflon catheter facilitated subcutaneous morphine delivery without local infection or hypotension.

Conclusions:

• Subcutaneous morphine administration via Insuflon catheter is a viable alternative to intravenous treatment for postoperative pain in neonates.
• This method ensures good pain control with a favorable safety profile in neonates.
• Further research with larger cohorts is warranted to confirm these findings.
