Abstract

Purpose

Flexible fiberoptic bronchoscopy (FFB) is a major diagnostic tool commonly used in intensive care unit (ICU). However, it generates discomfort and pain and can worsen respiratory and/or hemodynamic condition of critically ill patients. Remifentanil is an ultrashort-acting opioid drug that has been shown to provide effective sedation for painful procedures in spontaneous breathing patients. The aim of this study is to evaluate the safety and efficacy of sedation with remifentanil target-controlled infusion (Remi-TCI) in patients with spontaneous ventilation undergoing FFB in ICU.

Methods

Monocentric prospective study. All patients received Remi-TCI with initial effect-site target concentration of 2 ng/mL, progressively titrated according to their comfort and sedation. Respiratory and hemodynamic parameters were assessed before, during, and after the procedure, as well as comfort, level of sedation, FFB conditions, and recovery patterns. Global Remi-TCI data and potential complications of the procedure were also recorded.

Results

Fourteen patients were included. FFB was successful in all patients with good conditions (sedation, global comfort, and cough). No severe hemodynamic or respiratory complications occurred during procedure. Maximum target concentration and total dose of remifentanil were 2.5 ng/mL (2–4 ng/mL) and 1.4 μg/kg (0.7–2.4 μg/kg), respectively, over 10 min. Patients reported low level of pain and good satisfaction with the procedure.

Conclusions

FFB under sedation with Remi-TCI seems to be safe and effective in critically ill patients with spontaneous ventilation. Such results could be the first step towards wider use of Remi-TCI in patients experiencing awkward and/or painful procedures in this setting.
