Risk Factors for the Development of Postoperative Delirium in Pediatric Intensive Care Patients

Objectives: To determine and quantify risk factors for postoperative pediatric delirium. Design: Single-center prospective cohort study. Setting: Twenty-two bed PICU in a tertiary care academic medical center in Germany. Patients: All children admitted after major elective surgery (n = 93; 0–17 yr). Interventions: After awakening, children were screened for delirium using the Cornell Assessment of Pediatric Delirium bid over a period of 5 days. Demographic and clinical data were collected from the initiation of general anesthesia. Measurements and Main Results: A total of 61 patients (66%) were delirious.

Total IV anesthesia had a lower risk than inhalational anesthesia (p
