Abstract
Relevance: Oncological diseases remain the main cause of death in children, increasing the need for intensive care. Hospitalized children suffering from oncological diseases are at high risk for sudden deterioration of their condition, both for the underlying disease and due to infectious complications and the toxic effects of medications. This review highlights information on the Pediatric Early Warning Signs (PEWS) system in oncological patients to detect clinical deterioration promptly. The study aimed to analyze international literature on the use of pediatric early warning signs (PEWS) for clinical deterioration in pediatric oncology. Methods: Current literature on using the PEWS of clinical deterioration in pediatric oncology was studied. Results: The published data show the important role of using the PEWS system in cancer patients for early detection of deterioration of the condition with subsequent provision of emergency medical care. Conclusion: The analysis of international experience has shown that using the PEWS system in children with oncological diseases is an effective method of early recognition of signs of clinical deterioration, which, in turn, allows the timely initiation of complex intensive therapy.
