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

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.

Project description:Unlabelled♦BackgroundThe standard treatment of peritoneal dialysis (PD)-associated peritonitis (PD-peritonitis) is intraperitoneal (IP) administration of antibiotics. Only limited data on the pharmacokinetics and appropriateness of contemporary dose recommendations of IP cefalothin and cefazolin exist. The aim of this study was to describe the pharmacokinetics of IP cefalothin and cefazolin in patients treated for PD-peritonitis. ♦MethodsAs per international guidelines, IP cefalothin or cefazolin 15 mg/kg once daily was dosed with gentamicin in a 6-hour dwell to patients with PD-peritonitis during routine care. Serial plasma and PD effluent samples were collected over the first 24 hours of therapy. Antibiotic concentrations were quantified using a validated chromatographic method with pharmacokinetic analysis performed using a non-compartmental approach. ♦ResultsNineteen patients were included (cefalothin n = 8, cefazolin n = 11). The median bioavailability for both antibiotics exceeded 92%, but other pharmacokinetic parameters varied markedly between antibiotics. Both antibiotics achieved high PD effluent concentrations throughout the antibiotic dwell. Cefazolin had a smaller volume of distribution compared with cefalothin (14 vs 40 L, p = 0.003). The median trough total plasma antibiotic concentration for cefazolin and cefalothin during the dwell differed (plasma 56 vs 13 mg/L, p < 0.0001) despite a similar concentration in PD effluent (37 vs 38 mg/L, p = 0.58). Lower antibiotic concentrations were noted during PD dwells not containing antibiotic, particularly cefalothin, which was frequently undetectable in plasma and PD effluent. The median duration that the unbound antibiotic concentration was above the minimum inhibitory concentration (MIC) was approximately 13% (plasma) and 25% (IP) for cefalothin, and 100% (plasma and IP) for cefazolin, of the dosing interval. ♦ConclusionsWhen IP cefalothin or cefazolin is allowed to dwell for 6 hours, sufficient PD effluent concentrations are present for common pathogens during this time. However, with once-daily IP dosing, in contrast to cefazolin, there is a risk of subtherapeutic plasma and PD effluent cefalothin concentrations, so more frequent dosing may be required.
