Brief Summary:
This study is a comparison of two most commonly used modes of weaning and the outcomes in the two groups.

Condition or disease Intervention/treatment Phase
Respiration, Artificial Ventilator Weaning Procedure: Pressure support ventilation Procedure: Spontaneous breathing trials Not Applicable

Detailed Description:
Patients ventilated for more than 24 hours are randomized into two groups - one group of patients undergo gradual reduction of pressure support and in the other, T tube trials are used for weaning. The outcomes are compared in the two groups.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 130 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Health Services Research
Official Title: A Randomized Controlled Trial on Weaning by Pressure Support Reduction Versus Spontaneous Breathing Trials in a Respiratory ICU
Study Start Date : April 2008
Estimated Primary Completion Date : September 2009
Estimated Study Completion Date : September 2009

Arm Intervention/treatment
Active Comparator: Pressure support ventilation
Patients in this arm are weaned by gradual reduction of pressure support
Procedure: Pressure support ventilation
These patients are weaned by gradual reduction of pressure support and extubated when they tolerate a pressure support of 7 cm of water for one hour.
Other Name: weaning by reduction of pressure support

Active Comparator: Spontaneous breathing trials
Patients in this arm are weaned by T piece trials
Procedure: Spontaneous breathing trials
These patients are weaned by giving a T piece trial with 8 cm of water pressure support and extubated when they tolerate it for one hour.
Other Name: Weaning by T-piece trials




Primary Outcome Measures :
  1. Rate of weaning failure [ Time Frame: 48 hours from extubation ]

Secondary Outcome Measures :
  1. Occurence of ventilator associated pneumonia [ Time Frame: Until the date of discharge from hospital ]
  2. Reintubation rates [ Time Frame: 48 hours ]
  3. Mortality rates [ Time Frame: Until the time of discharge from hospital ]
  4. Duration from start of weaning to extubation [ Time Frame: In hospital stay ]
  5. Role of various factors that may influence the weaning outcome and hence predict the probability of successful weaning in a patient [ Time Frame: during ICU stay ]
  6. The influence of weaning outcome on mortality and the other complications of mechanical ventilation [ Time Frame: during hospital stay ]
