Inhaled acetylcysteine to prevent pneumonia in adults on mechanical ventilation
Official title: The Role of N-Acetylcysteine Inhalation in Critically Ill Mechanically Ventilated Patients
Run by Cairo University · NCT07409727 · Data updated 2026-11-12
This trial tests whether breathing in acetylcysteine instead of saline can lower the chance of getting ventilator-associated pneumonia or delay when it starts in adults on a ventilator.

Is this trial a fit for you?
✓Likely a good fit
Adult (18–64) critically ill patients who are intubated, expected to require mechanical ventilation for more than 48 hours, and whose next of kin can provide consent are the intended participants.
✕Probably not a fit
Patients already on long-term NAC, those who are pregnant, immunocompromised, brain dead, hemodynamically unstable (MAP <60 mmHg despite support), or ventilated at another hospital are excluded and unlikely to benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Critically ill adults who are intubated and expected to need mechanical ventilation for more than 48 hours will receive inhaled acetylcysteine or inhaled normal saline while in the ICU. The trial monitors whether acetylcysteine changes the incidence of ventilator-associated pneumonia and the time until pneumonia develops. Key exclusions include patients already on long-term NAC, those who are pregnant, immunocompromised, brain dead, or hemodynamically unstable. Outcomes include infection rates and timing of ventilator-associated complications during the ICU stay.
Why it matters
Potential benefit: If successful, inhaled acetylcysteine could reduce ventilator-associated pneumonia and shorten time on the ventilator and in the ICU.
How similar studies have gone: Prior small trials and observational studies of inhaled mucolytics including N-acetylcysteine have shown mixed and limited evidence for preventing ventilator-associated pneumonia, so effectiveness is not yet established.
