Efficacy and Safety of Remifentanil for Mechanically Ventilated Patients in Intensive Care Unit
- Registration Number
- NCT05641909
- Lead Sponsor
- Southeast University, China
- Brief Summary
Remifentanil has been approved by the FDA for continuation as an analgesic into the immediate postoperative period in adult patients under the direct supervision of an anesthesia practitioner in a postoperative anesthesia care unit or intensive care setting. However, National Medical Products Administration(NMPA) did not approve this indication. Therefore, the purpose of this study is to confirm the efficacy and safety of remifentanil in the analgesic therapy of critical ill patients in China.
- Detailed Description
The study was conducted in accordance with good clinical practice and with the guidelines set out in the Declaration of Helsinki. After approval from local and national ethics committees, patients from 18 centres in China were recruited. All patients were randomized, in a double-blind manner, to receive either a remifentanil-propofol regimen or a fentanyl-propofol regimen for analgesia and sedation in the ICU. The aim of the study was to achieve optimal sedation and patient comfort by maintaining an optimal Critical Care Pain Observation Tool (CPOT) score of 2, without clinically significant pain, until the start of the extubation process or for 72 hours, whichever occurred first. CPOT scoring criteria: Facial expressions(Relaxed, neutral=0; Tense=1; Grimacing=2); Body movements(Absence of movements or normal position=0; Protection=1; Restlessness/Agitation=2); Muscle tension(Relaxed=0; Tense, rigid=1; Very tense or rigid=2); Compliance with the ventilator or Vocalization(Tolerating ventilator or movement/Talking in normal tone or no sound=0; Coughing but tolerating/Sighing, moaning=1; Fighting ventilator/Crying out, sobbing=2).

Group Intervention Description Remifentanil Remifentanil Remifentanil analgesia combined with propofol sedation. Treatment was started in patients with an CPOT score of 2 or greater after completion of baseline assessments. All patients received an initial infusion of blinded opioid (placebo bolus dose(6ml) + 6ug/kg per hour infusion at 6 ml/hour). Optimal analgesia (CPOT score ≤2) was then targeted by titrating the infusion in 1.5 ml/hour increments (placebo bolus dose + 1.5ug/kg per hour rate increase). Only when the opioid infusion rate had reached the 'propofol trigger dose' (12ml/h; 12ug/ kg per hour) was propofol to be administered as an initial bolus dose of up to 0.5 mg/kg and an infusion of 0.5mg/kg per hour, and titrated in 25% increments (0.25mg/kg bolus dose + 0.125mg/kg per hour rate increase to treat agitation. Fentanyl Fentanyl Fentanyl analgesia combined with propofol sedation. Treatment was started in patients with an CPOT score of 2 or greater after completion of baseline assessments. All patients received an initial infusion of blinded opioid (1ug/kg bolus(6ml) + 1ug/kg per hour infusion at 6ml/hour). Optimal analgesia (CPOT score ≤2) was then targeted by titrating the infusion in 1.5 ml/hour increments (1ug/kg bolus dose + 0.25ug/kg per hour rate increase). Only when the opioid infusion rate had reached the 'propofol trigger dose' (12ml/h; 2ug/kg per hour) was propofol to be administered as an initial bolus dose of up to 0.5 mg/kg and an infusion of 0.5mg/kg per hour, and titrated in 25% increments (0.25mg/kg bolus dose + 0.125mg/kg per hour rate increase to treat agitation.
