Randomized Controlled Trial Multicenter Study
A randomized trial of the amikacin fosfomycin inhalation system for the adjunctive therapy of Gram-negative ventilator-associated pneumonia: IASIS Trial.
Clinical failures in ventilator-associated pneumonia (VAP) caused by gram-negative bacteria are common and associated with substantial morbidity, mortality, and resource utilization. ⋯ In this trial of adjunctive aerosol therapy compared with standard of care IV antibiotics in patients with gram-negative VAP, the AFIS was ineffective in improving clinical outcomes despite reducing bacterial burden.

Randomized Controlled Trial Comparative Study
A Randomised Clinical Trial Comparing the Effects of Antitussives on Respiratory Centre Output in Patients with Chronic Cough.
Cough is produced by the same neuronal pool implicated in respiratory rhythm generation, and antitussive drugs acting at the central level, such as opioids, may depress ventilation. Levodropropizine is classified as a nonopioid peripherally acting antitussive drug that acts at the level of airway sensory nerves. However, the lack of a central action by levodropropizine remains to be fully established. We set out to compare the effects of levodropropizine and the opioid antitussive agent dihydrocodeine on the respiratory responses to a conventional CO2 rebreathing test in patients with chronic cough of any origin. ⋯ The results are consistent with a peripheral action by levodropropizine; the assessment of ventilatory responses to CO2 may represent a useful tool to investigate the central respiratory effects of antitussive agents.
