Insights
Adverse events (AE) during invasive mechanical ventilation in the Pediatric Intensive Care Unit (PICU) affect 21.6% of patients. Post-extubation stridor and unplanned extubation are common, with longer hospital stays increasing AE risk.
Area of Science:
- Pediatric critical care medicine
- Patient safety
- Mechanical ventilation
Background:
- Invasive mechanical ventilation is crucial for critically ill children.
- Adverse events (AE) can complicate ventilation and impact outcomes.
- Understanding AE prevalence and risk factors is vital for improving care in the Pediatric Intensive Care Unit (PICU).
Purpose of the Study:
- To determine the prevalence of adverse events (AE) in pediatric patients receiving invasive mechanical ventilation.
- To identify factors associated with the occurrence of AE in this population.
- To inform strategies for reducing AE in the PICU.
Main Methods:
- A cross-sectional study was conducted over two years in a tertiary public hospital's PICU.
- Data on patient demographics, clinical status, ventilation parameters, and AE were collected.
- Logistic regression analysis was employed to identify factors associated with AE.
Main Results:
- A total of 306 patients were analyzed, with 21.6% experiencing at least one AE.
- The most frequent AE were post-extubation stridor (25.9%) and unplanned extubation (16.9%).
- A length of stay of 7 days or more was significantly associated with a higher occurrence of AE (OR=2.6).
Conclusions:
- A substantial proportion of pediatric patients on invasive mechanical ventilation experience preventable adverse events.
- Post-extubation stridor and unplanned extubation are key AE requiring attention.
- Longer hospitalization duration is a significant risk factor for AE, highlighting the need for targeted interventions.
Objective:
To identify the prevalence and factors associated with adverse events (AE) related to invasive mechanical ventilation in patients admitted to the Pediatric Intensive Care Unit (PICU) of a tertiary public hospital.
Methods:
This is a cross-sectional study from July 2016 to June 2018, with data collected throughout patients' routine care in the unit by the care team. Demographic, clinical and ventilatory characteristics and adverse events were analysed. The logistic regression model was used for multivariate analysis regarding the factors associated with AE.
Results:
Three hundred and six patients were included, with a total ventilation time of 2,155 days. Adverse events occurred in 66 patients (21.6%), and in 11 of those (16.7%) two AE occurred, totalling 77 events (36 AE per 1000 days of ventilation). The most common AE was post-extubation stridor (25.9%), followed by unplanned extubation (16.9%). Episodes occurred predominantly in the afternoon shift (49.3%) and associated with mild damage (54.6%). Multivariate analysis showed a higher occurrence of AE associated with length of stay of 7 days or more (Odds Ratio [OR]=2.6; 95% confidence interval [95%CI] 1.49-4.66; p=0.001).
Conclusions:
The results of the present study show a significant number of preventable adverse events, especially stridor after extubation and accidental extubation. The higher frequency of these events is associated with longer hospitalization.
