Prolonged Neuromuscular Blockade From Continuous Vecuronium in an Infant With Renal Failure Being Treated With...

Area of Science:

• Pediatric Critical Care Medicine
• Clinical Pharmacology
• Nephrology

Background:

• Neuromuscular blockade is essential for critically ill pediatric patients requiring mechanical ventilation or undergoing procedures.
• Vecuronium is a commonly used neuromuscular blocking agent, but its use in pediatric patients with renal impairment is not well-documented.
• Renal failure is suspected to prolong vecuronium's effects through the accumulation of active metabolites, as observed in adult and some pediatric cases.

Purpose of the Study:

• To report a case of prolonged neuromuscular blockade from vecuronium in an infant undergoing continuous renal replacement therapy.
• To highlight the impact of renal function on vecuronium's pharmacokinetics and duration of action in pediatric patients.
• To emphasize the importance of considering renal replacement therapy and renal function when selecting neuromuscular blocking agents.

Main Methods:

• Case report of an infant receiving vecuronium.
• Monitoring of neuromuscular blockade during and after continuous renal replacement therapy.
• Clinical observation of recovery from neuromuscular blockade.

Main Results:

• The infant experienced several days of prolonged neuromuscular blockade after vecuronium administration, despite cessation of the agent.
• Continuous renal replacement therapy did not fully mitigate the prolonged blockade, suggesting impaired clearance of active metabolites.
• The case illustrates the potential for extended paralysis in pediatric patients with renal failure exposed to vecuronium.

Conclusions:

• Vecuronium's neuromuscular blockade can be significantly prolonged in pediatric patients with renal failure, even during continuous renal replacement therapy.
• Accumulation of renally cleared active metabolites is the likely cause of extended paralysis.
• Clinicians must carefully consider the patient's renal function and the potential for prolonged neuromuscular blockade when using vecuronium in critically ill children.
