  Purpose

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


Condition Intervention
Respiration, Artificial
Ventilator Weaning
 Procedure: Pressure support ventilation
Procedure: Spontaneous breathing trials

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, 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

Further study details as provided by Postgraduate Institute of Medical Education and Research:

Primary Outcome Measures:
  • Rate of weaning failure [ Time Frame: 48 hours from extubation ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Occurence of ventilator associated pneumonia [ Time Frame: Until the date of discharge from hospital ] [ Designated as safety issue: Yes ]
  • Reintubation rates [ Time Frame: 48 hours ] [ Designated as safety issue: Yes ]
  • Mortality rates [ Time Frame: Until the time of discharge from hospital ] [ Designated as safety issue: Yes ]
  • Duration from start of weaning to extubation [ Time Frame: In hospital stay ] [ Designated as safety issue: Yes ]
  • 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 ] [ Designated as safety issue: Yes ]
  • The influence of weaning outcome on mortality and the other complications of mechanical ventilation [ Time Frame: during hospital stay ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 130
Study Start Date: April 2008
Estimated Study Completion Date: September 2009
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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

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.
