Objective To study the feasibility of using propofol and remifentanil for tracheal intubation in patients who are awake, and investigate the influence of tracheal intubation on such vital signs as blood pressure and heart rates. Methods Eighty ASA I-Ⅱ patients who underwent general anesthesia in our hospital between December 2012 and April 2013 were randomly divided into two groups. Patients in group A received fentanyl-propofol, while patients in group B received remifentanyl-propofol-lidocaine. There was no significant difference between the two groups in gender, age, and body weight (P>0.05). Conventional intubation induction method was used for group A:0.05-0.10 mg/kg midazolam, 4 μg/kg fentanyl, 1.0-1.5 mg/kg propofol, and 0.6-0.9 mg/kg atracurium were given and tracheal intubation was performed after muscle relaxation. Group B patients were treated with remifentanyl propofol-lidocaine compound liquid slow intravenous injection, and compound cricothyroid membrane puncture method before endotracheal intubation. We observed the two groups of patients for vital signs before and after induction, and choking cough reactions. Results Patients in both the two groups were all able to complete tracheal intubation. Circulation change and incidence of tachycardia in patients of group A were significantly higher than those in group B (P<0.05). The rates of bradycardia, hypoxemia, and choking cough response were low in both groups with no statistically significant difference (P>0.05). Conclusion Remifentanyl propofol-lidocaine compound liquid can be safely used for implementation of endotracheal intubation in patients who are awake, and the hemodynamic stability can be maintained.
