Epidemiological Survey of Children With Prolonged Mechanical Ventilation.

Study Overview
=================
Brief Summary
-----------------
Mechanical ventilation is an effective treatment for respiratory failure, no more than ten percent of patients with respiratory failure need long-term mechanical ventilation.

Detailed Description
-----------------
Mechanical ventilation is an effective treatment for respiratory failure, no more than ten percent of patients with respiratory failure need long-term mechanical ventilation. There is a lack of data on children with long-term mechanical ventilation in China.The investigators conducted this study to investigate the clinical characteristics of children with long-term mechanical ventilation in China. The investigators conducted a multicenter clinical epidemiological survey.The study included PICU wards in major children's hospitals in China and investigated the causes of prolonged mechanical ventilation, the outcome of long-term mechanical ventilation.PMV definition: continuous invasive or noninvasive ventilation time ≥ 21 days, daily ≥ 6 hours.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the cause of prolonged mechanical ventilation | This is a categorical variable. The reasons for the prolonged mechanical ventilation wolud be recorded, includes neuromuscular diseases, upper respiratory airway diseases, central nervous system diseases, lower respiratory airway diseases, abnormal ventilation control diseases. | At enrollment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| mortality rate | The mortality rate among patients received prolonged mechanical ventilation. | During the procedure (about 2 years) | 
| the length of prolonged mechanical ventilaton | The length of prolonged mechanical ventilaton among patients would be recorded during the hospitalization and after discharging. | During the procedure (about 2 years) |
