Predictors and outcomes of extubation failures in a pediatric intensive care unit: A retrospective study
1Department of Pediatric, Pediatric Critical Care Unit, Faculty of Medicine, King Abdulaziz University, Jeddah, KSA.
Insights
Extubation failure occurred in 12.5% of pediatric intensive care unit patients, particularly younger children. Dexamethasone administration significantly reduced extubation failure risk.
Area of Science:
- Pediatric Critical Care Medicine
- Respiratory Medicine
- Clinical Outcomes Research
Background:
- Extubation failure (EF) is a significant concern in pediatric intensive care units (PICUs), impacting patient outcomes and resource utilization.
- Identifying risk factors and effective interventions for EF is crucial for improving care in critically ill children.
Purpose of the Study:
- To determine the extubation failure rate in a PICU.
- To assess the causes, associated risk factors, and outcomes of extubation failure in pediatric patients.
- To evaluate the efficacy of dexamethasone in mitigating extubation failure.
Main Methods:
- A retrospective study was conducted on 335 pediatric patients (1 month to 14 years) requiring invasive mechanical ventilation (MV) for over 24 hours.
- Extubation readiness was determined by attending physicians based on clinical status and established criteria.
- Data on patient demographics, primary diagnosis, MV duration, ICU stay, and interventions were analyzed.
Main Results:
- The overall extubation failure rate was 12.5% (42 out of 335 patients).
- Younger age, cardiovascular disease as the primary admission condition, higher Pediatric Risk of Mortality III (PRISM) scores, and longer duration of mechanical ventilation and ICU stay were significantly associated with EF.
- Dexamethasone administration prior to extubation was associated with a significant reduction in EF risk (28.3% reduction).
Conclusions:
- Younger pediatric patients exhibit a higher risk of extubation failure, potentially linked to prolonged ICU stays, extended MV requirements, and primary diagnoses.
- Dexamethasone administration demonstrates a promising role in effectively reducing the incidence of extubation failure.
- Further rigorous research is warranted to validate identified EF predictors and develop targeted strategies to prevent extubation failure in pediatric populations.
Objectives:
This study was aimed at determining the extubation failure (EF) rate in a pediatric intensive care unit (PICU), and assessing the etiology, associated risk factors, and outcomes.
Methods:
We conducted a retrospective study on 335 pediatric patients admitted to King Abdulaziz University Hospital between 2018 and 2020, ranging in age from 1 month to 14 years, who required invasive mechanical ventilation (MV) for >24 h. Extubation readiness was determined by the attending pediatric intensive care physician, according to the patients' clinical status and extubation readiness criteria.
Results:
In the cohort of 335 patients, 42 experienced issues during extubation (failure rate, 12.5%). Cardiovascular disease (42.9%) was the main primary admission condition in patients with EF. Younger age (median, interquartile range [IQR]: 4, 1.38-36 months) was strongly associated with EF compared with successful extubation (median, IQR: 12, 2-48; p = 0.036), and with a high predicted mortality rate (10.9%; p < 0.001) and Pediatric Risk of Mortality III (PRISM) score (13; p < 0.001). Furthermore, prolonged ICU stay (25.5 days; p < 0.001) and longer MV requirements (4 days; p < 0.001) before extubation in patients with EF were associated with a high mortality rate (∼12%; p < 0.001). Interestingly, dexamethasone administration before extubation significantly alleviated EF risk (28.3%; p < 0.001).
Conclusion:
A higher EF rate in younger patients may potentially be associated with longer ICU stays, prolonged MV requirements before extubation, and the primary diagnostic condition. Dexamethasone effectively alleviated EF incidence. Further research with a rigorous evidence-based study design is necessary to substantiate the factors identified as predictors of EF and to develop strategies to avoid EF.
