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.
RESULTS: A total of 58 patients were enrolled in this study. The targeted-volume NIV group was observed to have a trend toward lower reintubation rate within 48 hrs compared to oxygen mask group (0% vs. 17.2%; P = 0.052). Extubation failure rate within 48 hrs was significantly lower in targeted-volume NIV group compared to oxygen mask group (0% vs. 41.38%; P < 0.001). There was a trend toward lower ICU length of stay (6[5] days vs. 10[8] days (median interquartile range [IQR]); P = 0.053) as well as shorter hospital length of stay after extubation (10[19] days vs. 18[15] days (median [IQR]); P = 0.059). There were no differences in the incidence of ventilator-associated pneumonia (VAP)/hospital-acquired pneumonia (HAP) (6.90% vs. 20.69%;P = 0.253) and 28 day-mortality (13.79% vs. 20.69%; P = 0.487).
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.
