Abstract

Background: This study was conducted with the aim of comparing the sedation rate of Propofol and Lidocaine -Propofol combination in patients undergoing bronchoscopy.

Methods: In this clinical trial study, 60 patients undergoing bronchoscopy were divided into two groups of 30 people, in the first group 1 mg/kg of Propofol and in the second group 1 mg/kg of Propofol together with 1.5 mg/kg of Lidocaine were injected. And the hemodynamic parameters, depth of sedation, consumption of Propofol and midazolam, and pain intensity after the operation were evaluated and compared between two groups.

Results: Patients in the propofol-Lidocaine group had better hemodynamic stability and the trend of sedation score changes was significantly different between the two groups (P=0.042). In terms of pain intensity during recovery, propofol-Lidocaine recipients had less pain intensity (P<0.001). Patients receiving propofol-Lidocaine received less Propofol (P=0.028) and midazolam (P=0.01).

Conclusion: The results of the present study show that the use of injectable Lidocaine with Propofol is associated with more favorable hemodynamic stability, reduction of Propofol consumption, better sedation, and less postoperative pain, so it seems that the use of Lidocaine with Propofol is beneficial. It is preferable to Propofol alone.
