Continuous lumbar/thoracic epidural analgesia in low-weight paediatric surgical patients: practical aspects and...

Area of Science:

• Pediatric Anesthesiology
• Neonatal Surgery
• Pain Management

Background:

• Continuous epidural anesthesia is known to reduce perioperative stress and opioid requirements.
• It may also prevent the need for postoperative mechanical ventilation in infants.
• This study focuses on the perioperative course of young infants receiving continuous thoracic/lumbar epidural anesthesia.

Purpose of the Study:

• To prospectively evaluate the safety and efficacy of continuous thoracic/lumbar epidural anesthesia in young infants undergoing major surgery.
• To assess the perioperative outcomes, including analgesia quality and complications.
• To identify factors influencing the need for mechanical ventilation and extubation timing.

Main Methods:

• Prospective data collection from 44 epidural anesthetics in 40 infants (18 premature or former premature) weighing 1,400-4,300 g.
• Infants underwent major abdominal, thoracic, or ano-rectal surgery.
• Data included epidural placement success, analgesia duration, and intra/postoperative complications.

Main Results:

• Epidural placement was successful in all cases, providing 24-96 hours of high-quality analgesia.
• Tracheal extubation was delayed in 4 cases due to various reasons, including muscle relaxant overdose and prior opioid administration.
• Intraoperative complications included hemodynamic instability (1) and vascular catheter placement (5). Postoperative complications included meningitis (1), erythema (7), apnea (6), and re-intubation (6).

Conclusions:

• Continuous epidural analgesia is effective for low-weight infants undergoing major surgery.
• Immediate tracheal extubation after surgery is feasible.
• Careful monitoring for pain, respiratory failure, and meningitis is crucial, considering the unique aspects of infant physiology and pharmacology.
