Neonatal IV drug compatibility

Abstract:

Aim: Incompatibility of intravenous drugs is dangerous and therefore undesirable. The aim of this study was to identify the most commonly acquired intravenous drugs in five neonatal intensive care units and test these for compatibility.

Methods: The most frequently acquired drugs in five key hospitals in the South-Eastern district of Norway for 2019 and 2020 served as a proxy for prevalence of use. . Representatives were selected from the three most prevalent groups based on the Anatomical Therapeutic Chemical classification system. Co-administration of drug pairs was simulated using clinically relevant concentrations and infusion rates representing mixing ratios in the catheter. Particle formation was assessed by particle counting and size measurement, by visual examination using Tyndall-beam, by turbidiy, and by measuring pH of mixed samples.

Results: The most frequently acquired drug groups were anti-infectives, neurological agents, and cardiovascular drugs. Compatibility testing revealed that both ampicillin and benzylpenicillin were incompatible with morphine. Flecainide and fluconazole showed no signs of incompatibility with morphine. No information on these combinations in a neonatal-relevant setting is available.

Conclusion: We recommend to abstain from co-administering ampicillin and benzylpenicillin with morphine in neonatal intensive settings. Morphine co-administered with flecainide and fluconazole in neonatal patients were evaluated as safe.
