Use of Electrical Impedance Tomography in Children With Syndrome of Acute Respiratory Disorder
In Brief
A clinical study evaluating PEEP Titriation for Respiratory Distress Syndrome. Completed, enrolled 20 participants across 1 site.
Detailed Summary
INTRODUCTION: Electrical impedance tomography is a tool for noninvasive monitoring of pulmonary ventilation in real time, which is used during alveolar recruitment maneuvers in patients with acute respiratory distress syndrome. OBJECTIVES: To identify ventilatory and hemodynamic changes during the alveolar recruitment maneuver in children with acute respiratory distress syndrome using electrical impedance tomography. METHODS: Twenty children, aged 4 to 12 years, who present a diagnosis of respiratory distress syndrome, with indication of alveolar recruitment admitted to the Pediatric Intensive Care Unit of the Santa Casa de Misericórdia Foundation of Pará will be selected. Data collection will consist of three before the alveolar recruitment maneuver, immediately after the alveolar recruitment maneuver, 2 hours after the alveolar recruitment maneuver, where the pulmonary ventilation distribution, the driving pressure, the real-time reading compliance will be analyzed. tomography of the Timpel brand, autonomic heart rate modulation through the Polar® RS800CX device, physiological variables such as heart rate, oxygen pulse saturation and blood pressure by measuring the DIXTAL multi-parameter monitor, blood oxygen pressure and the oxygen content dog. The statistical analysis will be performed in the Biostat 5.2 program, and the choice of tests will depend on the types of distributions found and the homogeneity of the respective variances.

Timeline
Interventions
The alveolar recruitment maneuver PEEP reaches a maximum of 25 cmH2O, with recruitment being performed progressively, where the pressure variation is maintained at 15 cmH2O and the PEEP increase progressively occurs at 2 cmH2O every 2 minutes and Ventilatory mode with Controlled Pressure Ventilation. After the alveolar recruitment maneuver, the PEEP titration or determination will be performed, where the PEEP of 2 cmH2O will be reduced every 2 minutes and the variables after the alveolar recruitment maneuver and PEEP maintenance will be checked in the TIMPEL brand equipment at the point where the patient has better alveolar recruitment, with fewer alveolar collapsing points and pulmonary hyperdistension.
