Abstract

OBJECTIVE:

To assess the feasibility and safety of remifentanil-based sedation during noninvasive ventilation (NIV) in patients with NIV failure.

DESIGN AND SETTING:

Prospective clinical investigation in a 16-bed intensive care unit of a university hospital in France.

PATIENTS:

Thirteen patients in NIV failure due to discomfort and/or refusal to continue this ventilatory support: 10 with acute respiratory failure and 3 with acute hypercapnic respiratory failure.

INTERVENTION:

Patients were administered methylene blue and were sedated (Ramsay scale 2-3) by a continuous perfusion of remifentanil during NIV. Cardiorespiratory and ventilatory parameters, blood gas analysis, and adverse events were prospectively recorded.

MEASUREMENTS AND RESULTS:

The 13 patients received a total of 125 NIV sessions, totaling 1200 h, of NIV under remifentanil-based sedation (mean remifentanil dose 0.1+/-0.03 microg/kg per minute). Three patients also required propofol. PaO2/FIO2 ratio increased from 134+/-69 to 187+/-43 mmHg after 1 h. In patients with acute respiratory failure respiratory rate decreased from 34+/-12 per minute before remifentanil to 25+/-4 per minute after 1h. In the three patients with acute hypercapnic respiratory failure PaCO2 decreased from 69+/-7 to 42+/-5 mmHg. Four patients required endotracheal intubation without aspiration pneumonia. Twelve of the 13 patients left the ICU.

CONCLUSION:

This pilot study shows that remifentanil-based sedation is safe and effective in the treatment of NIV failure due to low tolerance.
