Insights
Nosocomial infections (NI) affected 45% of pediatric patients on mechanical ventilation (MV). Ventilator-associated pneumonia (VAP) was the most common NI, with MV duration and invasive procedures as key risk factors.
Area of Science:
- Pediatric Intensive Care
- Infectious Diseases
- Critical Care Medicine
Background:
- Nosocomial infections (NI) are a significant concern in pediatric intensive care units (PICUs).
- Mechanical ventilation (MV) is a common intervention associated with increased risk of NI.
- Understanding NI prevalence and risk factors in PICU patients is crucial for patient outcomes.
Purpose of the Study:
- To determine the frequency of nosocomial infections (NI) in pediatric patients requiring mechanical ventilation (MV).
- To identify the types of NI and their causative agents.
- To investigate risk factors associated with the development of NI, particularly ventilator-associated pneumonia (VAP).
Main Methods:
- Retrospective analysis of 60 pediatric patients admitted to a PICU who required MV.
- Data collection on patient demographics, MV duration, invasive interventions, and types of NI.
- Microbiological analysis to identify causative pathogens.
Main Results:
- The overall NI rate was 45% among pediatric patients on MV.
- Ventilator-associated pneumonia (VAP) was the most frequent NI, accounting for 66.7% of cases.
- Pseudomonas aeruginosa was the predominant pathogen in VAP. Duration of MV and invasive interventions were identified as significant risk factors for VAP.
Conclusions:
- Nosocomial infections, especially VAP, are common in mechanically ventilated pediatric patients.
- Prolonged MV and invasive procedures increase the risk of VAP.
- Targeted infection control strategies focusing on reducing MV duration and invasive interventions are essential.
Abstract:
Of 480 patients admitted to the Pediatric Intensive Care Unit of the Institute of Child Health Children's Hospital in Istanbul, 97 required mechanical ventilation (MV). Sixty of these children were included in a retrospective analysis aiming to determine the frequency of and factors contributing to the development of nosocomial infections (NI). NI rate was 45 percent, ventilator-associated pneumonia (VAP) accounted for the greater part (66.7%) of the NI, followed by urinary tract infections (16.7%), septicemia (13.3%), and meningitis (3.3). Pseudomonas aeruginosa was the most frequent cause of VAP. The duration of the MV and invasive interventions were important risk factors for the development of VAP.
