Detailed Description
Total of 9 pediatric critical care centers all across the country will collaborate at this study:
- Akdeniz University Faculty of Medicine, Pediatric Critical Care Division
- Cukurova University Faculty of Medicine, Pediatric Critical Care Division
- Ege University Faculty of Medicine, Pediatric Critical Care Division
- Ankara University Faculty of Medicine, Pediatric Critical Care Division
- Ondokuz Mayis University Faculty of Medicine, Pediatric Critical Care Division
- Erciyes University Faculty of Medicine, Pediatric Critical Care Division
- Koc University Faculty of Medicine, Pediatric Critical Care Division
- Dokuz Eylül University Faculty of Medicine, Pediatric Critical Care Division
- Izmir Katip Celebi University Faculty of Medicine, Pediatric Critical Care Division Since nature of this study is an observational cohort, all noninvasively ventilated children from one month to eighteen years will be enrolled in this study. A three-page questionnaire is designed to collect data. The first page includes information on epidemiological data, underlying disease in terms of both acute and chronicle problems resulting in respiratory problems; the second page includes a multi-colon table to record vital signs (heart and respiratory rate, systemic and diastolic blood pressure), PRISM-III and Pediatric logistic organ dysfunction (PELOD) scores, Glasgow coma scale, blood gas values, ventilation parameters, necessity of sedation (if so, drugs used for sedation) and finally comfort pain scores. Data will be collected immediately prior to commencing NIV, the first, second and sixth hours; if NIV support continues over 24 hours, then daily data will be obtained up to five days. Last questionnaire page consists of data for clinical outcome, reason of NIV failure, necessity of re-intubation and if so timing of re-intubation.
Primary outcome of this study is to observe success rates in decreasing necessity of mechanical ventilation or re-intubation. Successfully managed children will also be evaluated for age groups, underlying disease as well as modes of delivery and ventilation parameters to define thresholds on decision of NIV success or failure. Secondary outcome is to evaluate the NIV failure in terms of pediatric age groups, underlying disease, rates of NIV-related complications. If a respiratory failure occurs, modes of delivery and ventilation parameters, usage of different masks, timing of failure decision according to patients' clinical data will be explored from collected data.
Each center will fill in the questionnaire according to patient data and every two months period data will be collected from collaborators. After one year period, statistical evaluation will be investigated by the principle investigators.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To determine the incidence of NIV failure in children requiring invasive mechanical ventilation
Time Frame: one year
|
NIV failure is defined as necessity of endotracheal intubation due to respiratory insufficiency within 48 hours in children receiving noninvasive ventilation in pediatric critical care units.
Statistical analysis will be performed according to answers to form-I question-6 and form-III question-1 in the questionnaire.
|
one year
|
To determine the incidence of NIV failure as re-intubation within 48 hours.
Time Frame: 1 year
|
NIV failure is also determined as re-intubation within 48 hours for those who were previously intubated and received noninvasive ventilation following extubation.
Second primary outcome will be evaluated by Form - I question-6 and Form - III question-1.
|
1 year
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To determine the reasons resulting in NIV failure in children enrolled in the study
Time Frame: one year
|
Reasons of NIV failure is classified as; patient - ventilator asynchrony, face-mask mismatch, significant leakage percentage, progression to respiratory insufficiency [SpO2/FiO2<193 within the first hour; FiO2 necessity > %80 within two hours; blood gas pH<7.25 within two hours; failure to achieve 10 % expected decrease in respiratory rate within sixth hours, increase in clinically observed respiratory effort or progression to severe ARDS (Oxygenation index > 8)], neurologically deteriorating patient (Glasgow coma score < 8 or a decrease in score more than three units), risk of aspiration or bulbar dysfunction (loss of swallowing), hemodynamic instability, presence of arrhythmia and pneumothorax.
Underlying causes of NIV failure will be evaluated by answers to question-2 in Form III.
|
one year
|
To explore complication rates directly related to noninvasive ventilation.
Time Frame: one year
|
Complications related to noninvasive ventilation are loss of skin intact, development of pneumothorax, puking and related aspiration pneumonia, and hemodynamic instability.
Form - III question 3 will enlighten the incidence and the variety of complications.
|
one year
|
To observe NIV success for those who receive noninvasive ventilation over 48 hours
Time Frame: one year
|
Evaluation of answers to Form III questions 4-5-6 will demonstrate the NIV success for those who receive noninvasive ventilation over 48 hours as the third secondary outcome.
Daily ventilation breaks and length of noninvasive support per day (day 1 to day 5) will also be recorded by investigators to investigate the association of NIV success and noninvasive durations by applying multiple logistic regression analysis.
|
one year
|
To explore prognosis of patients receiving noninvasive ventilation
Time Frame: one year
|
Final secondary outcome will be the exploration of prognosis and the interactions between efficiency of noninvasive ventilation by length of intensive care unit and hospital stay and as well as mortality regarding answers to questions six and seven in Form -III.
