Potentially Hazardous Drugs in the Paediatric ICU: A Narrative Review on the Exemplary Cases of Propofol, Chloramphenicol, and Acetylsalicylic Acid.

Background: In the paediatric intensive care unit (PICU), certain drugs should be avoided or administered with strict precautions and close monitoring. This is due to their potential for toxicity or adverse effects or a lack of safety data, especially for critically ill children with organ failure. Additionally, practitioners must assess the unique pharmacokinetic and pharmacodynamic properties of drugs when treating critically ill children. In this narrative review, we highlight the risks, advantages, and disadvantages of three exemplary cases of drugs for paediatric patients hospitalised in the PICU: chloramphenicol, acetylsalicylic acid, and propofol. Methods: Apart from key papers on these drugs, a retrospective analysis of the English literature on chloramphenicol, acetylsalicylic acid (ASA), and propofol was performed on PubMed for papers from January 2014 to December 2025. Results: Chloramphenicol should be avoided in neonates due to the risk of grey baby syndrome. Acetylsalicylic acid (ASA) is contraindicated in children ≤18 years with suspected viral illness because of the risk of Reye's syndrome, but remains essential for Kawasaki disease and post-cardiac surgery antiplatelet therapy. Propofol should be avoided when used for a longer period at high doses. With proper dosing and monitoring, propofol-related infusion syndrome (PRIS) is preventable, but high-risk patients should receive alternative treatment. Conclusions: This narrative review highlights the significant risks associated with the use of chloramphenicol, ASA, and propofol in paediatric intensive care settings. Their potential for life-threatening and severe adverse reactions emphasises the need for cautious and informed use. Clinicians must carefully consider the risks and benefits of these drugs. To minimise adverse events, strict monitoring, dose adjustments, and the use of safer alternatives are essential. However, it appears that their use in well-defined circumstances in acute illness in children is still warranted. The findings of this narrative review underscore the need for further research to focus on identifying high-risk biomarkers, genetic predispositions, and safer alternatives to improve evidence-based guidelines and reduce morbidity and mortality in paediatric intensive care.
