Insights
Postoperative pediatric delirium is common, affecting 66% of children after major surgery. Risk factors include younger age, invasive devices, infections, and inhalational anesthesia.
Area of Science:
- Pediatric critical care medicine
- Anesthesiology
- Neuroscience
Background:
- Postoperative delirium is a significant concern in pediatric intensive care units (PICUs).
- Identifying risk factors is crucial for developing preventative strategies.
Purpose of the Study:
- To determine and quantify risk factors for postoperative pediatric delirium.
- To establish a baseline for future delirium prevention and treatment strategies in children.
Main Methods:
- Prospective cohort study in a tertiary care academic medical center in Germany.
- Screened 93 children (0-17 years) after major elective surgery for delirium using the Cornell Assessment of Pediatric Delirium over 5 days.
- Collected demographic and clinical data from anesthesia initiation.
Main Results:
- 66% of patients (61/93) experienced delirium, with younger children showing more pronounced symptoms.
- Risk factors identified include younger age, invasive catheters, respiratory devices, infections, and inhalational anesthesia.
- Delirium was associated with longer mechanical ventilation duration and differences in medication cumulative doses, independent of disease severity.
Conclusions:
- High prevalence of postoperative delirium in pediatric surgical patients.
- Identified key perioperative risk factors that can inform clinical practice.
- Data supports the development of targeted interventions to reduce pediatric delirium.
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. Younger children developed delirium more frequently, and the symptoms were more pronounced. The number of preceding operations did not influence the risk of delirium. Total IV anesthesia had a lower risk than inhalational anesthesia (p < 0.05). Duration of anesthesia was similar in all groups. Patients with delirium had a longer duration of mechanical ventilation in the PICU (p < 0.001). Significant differences in cumulative doses of various medications (e.g., sedatives, analgesics, and anticholinergics) were noted between groups; these differences were independent of disease severity. Invasive catheters and respiratory devices (p < 0.01) as well as infections (p < 0.001) increased risk of delirium.
Conclusions:
A high prevalence of delirium was noted in the PICU, and several perioperative risk factors were identified. Our data may be a base for development of strategies to prevent and treat postoperative delirium in children.
