Abstract
Neuromuscular blockade may be required in critically ill pediatric patients to facilitate ventilator synchrony or maintain safety during high-risk procedures. Vecuronium is one neuromuscular blocking agent used for this purpose; however, there are limited data regarding its use in pediatric patients with renal failure. Although predominantly considered to be metabolized by the liver, there are numerous adult cases and 1 pediatric case report that have described extended paralysis from vecuronium due to renal failure. The proposed mechanism is accumulation of renally cleared active metabolites. This case report describes an infant with vecuronium exposure during continuous renal replacement therapy who experienced prolonged neuromuscular blockade for several days after the agent was stopped. This highlights the importance of considering renal function when selecting neuromuscular blocking agent.
