Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In 2023, the second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) updated the diagnostic and management guidelines for Pediatric Acute Respiratory Distress Syndrome (PARDS). The guidelines do not provide sufficient evidence-based recommendations on whether prone positioning ventilation is necessary for severe PARDS patients. However, the effectiveness of Extracorporeal Membrane Oxygenation (ECMO) in treating severe PARDS has been fluctuating around 70% according to recent data from Extracorporeal Life Support Organization (ELSO).

In 2018, the Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) study group conducted a retrospective analysis and concluded that ECMO does not significantly improve survival rates for severe PARDS. However, this retrospective study mainly focused on data from North America, with significant variations in annual ECMO support cases among different centers, which may introduce bias. With advancements in ECMO technology and materials, ECMO has become safer and easier to operate. In recent years, pediatric ECMO support technology has rapidly grown in mainland China and is increasingly being widely used domestically to rescue more children promptly.

ECMO can also serve as a salvage measure for severely ARDS children who have failed conventional mechanical ventilation treatment. When optimizing ventilator parameters (titrating positive end expiratory pressure (PEEP) levels, neuromuscular blockers, prone positioning), strict fluid management alone cannot maintain satisfactory oxygenation (P/F\<80mmHg or Oxygen Index (OI) \>40 for over 4 hours or OI \>20 for over 24 hours), initiating ECMO can achieve lung-protective ventilation strategies with ultra-low tidal volumes to minimize ventilator-associated lung injury.

prone position during ECMO in pediatric ARDS

Procedure: Prone positioning The process of prone positioning requires 5-6 people, with one person acting as the commander responsible for directing and monitoring the implementation of prone positioning. The process of monitoring includes ECMO flow and vital signs. The second person is in charge of the patient's head, including endotracheal intubation, ventilator lines, and jugular ECMO cannula. The third person is responsible for femoral ECMO cannula and central venous line. The fourth to sixth individuals are responsible for rotating the patient's torso towards the side without an ECMO tube. Before initiating prone ventilation, pressure ulcer protection patches should be placed to protect areas under pressure. During ECMO support period, each patient needs to undergo at least four sessions of prone ventilation. Each session should last between 16 to 24 hours.

Intervention Type PROCEDURE

The process of prone positioning requires 5-6 people, with one person acting as the commander responsible for directing and monitoring. The process of monitoring includes ECMO flow and the vital signs. The second person is in charge of the patient's head, including endotracheal intubation, ventilator lines, and jugular ECMO cannula. The third person is responsible for femoral ECMO cannula and central venous line. The fourth to sixth individuals are responsible for rotating the patient's torso towards the side without an ECMO tube. Before initiating prone ventilation, pressure ulcer protection patches should be placed on the patient's forehead, ears, anterior chest, and iliac crest to protect areas under pressure. During ECMO support period, each patient needs to undergo at least four sessions of prone ventilation until their condition improves enough to discontinue ECMO support. Each session should last between 16 to 24 hours.
