Pediatric delirium in times of COVID-19 - Critical Care Science (CCS)
Revista Brasileira de Terapia Intensiva. 01-24-2021;33(4):483-486
Delirium is defined as a neurocognitive syndrome characterized by the acute onset of brain dysfunction with fluctuations in the basal mental state, inattention and disorganized thinking or altered levels of consciousness.(,) It is a frequent complication in intensive care units (ICUs).() Its occurrence is strongly predictive of an increase in the duration of mechanical ventilation (MV), length of stay in the ICU and hospital, risk of falls, hospital costs and mortality.()
Data from the literature show that the exact incidence of delirium in pediatric patients is still unknown and ranges from 0.84% to 66%. The prevalence is also quite variable at between 13% and 66% and has been well characterized since the implementation of valid screening tools for delirium in pediatric populations. Higher prevalence values of between 50% and approximately 70% were reported in critically ill children under 5 years of age, those on MV, during the postoperative period of cardiac surgery and during the immediate postoperative period after general anesthesia and elective surgery. However, underdiagnosis or incorrect diagnosis of delirium may occur when it is based only on the clinical experience of the team, without the use of a valid and reliable tool.(,,)
