The Use of Remifentanil without Muscle Relaxant for Intubation in Short-Timed, Elective Surgeries

Our aim studied to observe the effectivity of remifentanil on the hemodynamic response and condition of intubation on intubation without a muscle relaxant using a combination with propofol. A total of six patients aged 25–60 years with the American Society of Anesthesiology physical status I–II underwent elective oncologic surgery. Patients received premedication midazolam 0.05 mg/kg and induction with propofol 2 mg/kg and remifentanil 2 ?g/kg intravenously over 60 s. Systolic blood pressure, diastolic blood pressure, and heart rate were observed before premedication, before intubation, and postintubation. Intubation condition was assessed using the Copenhagen Consensus Score based on the ease of laryngoscopy, the position and movement of the vocal cord, and reacting to intubation. All patients were intubated without problem, and the intubation condition was excellent. One patient had hypotension and could be treated by administering the fluids and vasoconstrictor. The other remaining patients were stable without significant hemodynamic changes. A combination of propofol with remifentanil could provide excellent intubation condition and maintaining hemodynamic stability
