Summary

There are no specific drugs or therapies available to directly treat/prevent ARDS. Mechanical ventilation with an aim to minimize Ventilator Induced Lung Injury (VILI) and management of refractory hypoxemia are the keystones in supportive management of ARDS.

Detailed description

Furosemide: Nebulized furosemide has been studied as a potential treatment option for ARDS patients due to its diuretic properties and potential to reduce pulmonary edema. Research on the effectiveness of furosemide nebulization in ARDS patients could provide valuable insights into its potential role in managing respiratory distress and improving outcomes. Furosemide may reduce pulmonary edema via diuretic and anti-inflammatory effects. Heparin: Nebulized heparin has been proposed as a treatment for ARDS patients due to its anti-inflammatory and anticoagulant effects. By investigating the effectiveness of heparin nebulization in reducing pulmonary inflammation and improving oxygenation in ARDS patients, clinicians can gain a better understanding of its therapeutic potential in this critical condition. - ARDS involves fibrin deposition in alveoli, worsening compliance. Heparin may reduce microthrombosis and inflammation (anti-TNF-α effects). Hypertonic saline: Nebulized hypertonic saline has been suggested as a potential therapy for ARDS patients due to its ability to reduce airway inflammation and improve mucociliary clearance. Examining the effectiveness of hypertonic saline nebulization in ARDS patients could offer valuable insights into its impact on respiratory function and recovery in this challenging patient population. Hypertonic saline may improve mucus clearance and alveolar fluid absorption.

• Mechanical Ventilation Complication

Interventions

Type	Name	Description
DRUG	nebulization	Study solutions will be administered via a vibrating mesh nebulizer (Aerogen® Pro, Aerogen Ltd, Ireland) placed at the Y-piece of the ventilator circuit, proximal to the patient. The nebulizer will be used with its specific T-piece adapter. The nebulizer will be placed at the Y-piece (proximal to the patient), between the endotracheal tube and the circuit. To optimize aerosol delivery, a standardized nebulization protocol will be followed. For the 30-minute duration of each treatment, the ventilator will be set to Volume Control or Assist-Control mode with a constant inspiratory flow of 40-50 L/min, an inspiratory-to-expiratory ratio of 1:3, and an end-inspiratory pause of 0.5 seconds. The heated humidifier will be turned off 15 minutes before and bypassed during the nebulization period. Immediately after the 30-minute nebulization is complete, the humidification chamber will be reconnected, and the heated humidifier will be turned back on.
