Primary Outcome Measures:
  • Number of Patients With Cure, Improved, Failure or Death [ Time Frame: through study completion, an average of 2 weeks ]

    Clinical outcome is classified in 4 categories:

    Cure Improved Failure Death



Secondary Outcome Measures:
  • Number of Patients With Eradication, Persistence or Superinfection [ Time Frame: through study completion, an average of 2 weeks ]

    Microbiological response is classified in 4 categories:

    Eradication Persistence Superinfection


  • Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to Study Drug, Graded According to NCI CTCAE Version 3.0 [ Time Frame: through study completion, an average of 2 weeks ]
    Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to Study Drug, Graded According to NCI CTCAE Version 3.0 focus on neurology and bronchospasm. Nephrotoxicity uses RIFLE criteria for acute kidney injury. RIFLE is an acronym of Risk, Injury, and Failure; and Loss; and End-stage kidney disease.


Estimated Enrollment: 62
Study Start Date: December 2015
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: May 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: inhaled colistin
Inhaled colistin 75 mg mixed with normal saline up to 4 ml every 12 hours at least 5 days
Drug: Inhaled colistin
75 mg of colistin activity, inhaled per dose, every 12 hours
Other Name: Colistate 150

Detailed Description:

Patients diagnosed ventilator-associated tracheobronchitis due to gram negative organism are included to the study.The patients will be received colistin inhalation 75 mg every 12 hours at least 5 days.

The primary objective is to evaluate clinical outcome of inhaled colistin. The secondary objectives are microbiological clearance and toxicity of inhaled colistin.

The sample size was estimated to 62 patients.
