Investigating neuromuscular blockade effects on pain after laparoscopic surgery in children

Effect of Deep Neuromuscular Blockade on Postoperative Pain in Pediatric Patients Undergoing Laparoscopic Surgery: a Prospective Randomized Controlled Trial

Not applicable Interventional Seoul National University Hospital · NCT06679569

This study tests if using different amounts of a muscle relaxant during laparoscopic surgery can help reduce pain in children aged 2 months to under 7 years after their operation.

What this trial studies

This study examines how different levels of neuromuscular blockade affect postoperative pain in pediatric patients aged over 2 months to under 7 years who are undergoing laparoscopic surgery with general anesthesia. Participants will receive either a low or high dose of rocuronium via continuous infusion during their procedure. The goal is to determine if the degree of neuromuscular blockade can influence pain management outcomes in this population. The findings could provide insights into optimizing anesthesia practices for young patients.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged over 2 months to under 7 years scheduled for laparoscopic surgery under general anesthesia.

Not a fit: Patients undergoing emergency surgery or those with chronic pain conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for pediatric patients after surgery.

How similar studies have performed: While there may be studies on neuromuscular blockade, this specific investigation into its impact on postoperative pain in pediatric patients is relatively novel.
