Targeted-Volume Noninvasive Ventilation Reduces Extubation Failure in Postextubated Medical Intensive Care Unit Patients: A Randomized Controlled Trial

PURPOSE: Till date, the benefit of using noninvasive ventilation (NIV) routinely after extubation to prevent reintubation has been conflicting. We aim to demonstrate the effect of targeted-volume NIV for the prevention of reintubation and extubation failure after planned extubation in medical intensive care unit (ICU) patients. STUDY DESIGN: This was a prospective, randomized controlled study. MATERIALS AND METHODS: Patients on invasive mechanical ventilation for more than 48 hrs for acute respiratory failure, who were ready for extubation, were randomized into targeted-volume NIV (intervention group) or oxygen mask (controlled group) immediately after extubation and continuously for 24 hrs. CONCLUSIONS: Our study is the first study to demonstrate the benefit of application of targeted-volume NIV immediately after extubation in reducing extubation failure rate. There was a trend toward lowering reintubation rate and shorter ICU length of stay and hospital length of stay after extubation in mixed medical ICU patients.
