Abstract
Objective: The primary objective of this study was to investigate the prevalence of intensive care unit (ICU) pediatric delirium in Shanghai, China. Secondary objectives were to determine the association of hypoxia and infection with ICU pediatric delirium, and the impact between different age. Design: Prospective single-center observational study. Setting: Two pediatric intensive care unit (PICU) within a tertiary-A general hospital. Patients: Patients age between 1 month to 7 years in PICU who stayed at least 1 day were included. Convenance sampling was used. Interventions: None. Measurements and Main Results: Pediatric patients (n=639) were screened twice a day for the prevalence of ICU pediatric delirium by Cornell Assessment of Pediatric Delirium, 300 (46.95%) of them had infection and 213 (33.33%) had hypoxia in PICU. Children who suffered hypoxia remained more than three times likely to be delirious during their hospitalization compared with children who were not hypoxia, after controlling other covariates, the odds of pediatric delirium for subjects with hypoxia was 3.26 times (95% CI, 1.98-5.38) the odds without hypoxia. Also, the odds of pediatric delirium for subjects with infection was 2.55 times (95% CI, 1.58-4.11) the odds without infection adjusting for other covariates. After subgrouping by age, the occurrence of ICU pediatric delirium with infection for children younger than two years old was 5.37 times (95% CI, 3.09-9.33) compared with patients who were never infection, while that for the children equal to or older than two years old was no statistically significant relationship. Conclusions: The prevalence of ICU pediatric delirium was 31.30%, while there is an independent association of infection and hypoxia with ICU pediatric delirium. Furthermore, children younger than two years old took more risks on pediatric delirium when they were infected in this study, while there was no relationship between infection and pediatric delirium who aged 2 years or older.
