Pediatric Acute Respiratory Distress Syndrome Asia Study

Mortality rates in children with pediatric acute respiratory distress syndrome (PARDS) are higher in Asia compared to other regions. In adults with acute respiratory distress syndrome, the only therapy that improves mortality rates is a lung protective ventilation strategy. The pediatric ventilation recommendations are extrapolated from evidence in adults, including ventilation with low tidal volume, low peak/plateau pressures and high-end expiratory pressure. A recent retrospective study of ventilation practices in Asia showed varying practices with regards to pulmonary and non-pulmonary therapies, including ventilation. This study aims to determine the prevalence and outcomes of PARDS in the Pediatric Acute and Critical Care Medicine Asian Network (PACCMAN). This study will also determine the use of pulmonary (mechanical ventilation, steroids, neuromuscular blockade, surfactant, pulmonary vasodilators, prone positioning) and non-pulmonary (nutrition, sedation, fluid management, transfusion) PARDS therapies. To achieve this aim, a prospective observational study which involves systematic screening of all pediatric intensive care unit (PICU) admissions and collection of pertinent clinical data will be conducted. Recruitment will be consecutive and follow up will continue to intensive care discharge.

About this study

The overall objective of this study is to prospectively determine the epidemiology of children with PARDS and describe its management in Asia. The first specific aim is to determine the prevalence of PARDS among PICU admissions. This will be achieved by establishing a systematic manner of screening patients and including them in this study. The second specific aim is to describe the use of pulmonary and non-pulmonary therapies in PARDS. This study will utilize an established dataset to extract pertinent and analyzable clinical data.The third specific aim is to determine the outcome of patients with PARDS. These outcomes will include functional data, PICU mortality, ventilator duration and length of stay data. This is a two-part study - the first part to establish the baseline prevalence and ventilator management strategies, the second part will include the implementation of an evidence based ventilation protocol as part of routine care. The same screening process, eligibility criteria and data collection will apply throughout the two parts. We aim to obtain data for approximately 2years prior to and 2years subsequent to the implementation of the ventilator protocol.

Treatment and study plan

Ventilation protocol

Other

An evidence based ventilation protocol will be implemented at participating sites. This will include limits on peak inspiratory pressure (28cmH2O), driving pressure (16cmH2O), tidal volume (mild 8ml/kg, mod/severe 6ml/kg), positive end expiratory pressure to fraction of inspired oxygen table, permissive hypercarbia (mild allow pH 7.30, mod/severe allow pH 7.20) and permissive hypoxia (mild SpO2 92-97%, mod/severe SpO2 88-92%).
