Abstract:

Objective: The main purpose of this study is to investigate the most effective and reliable method for prevention of propofol injection pain. Material and Methods: In this prospective, randomized, double-blind trail we gave one of the six drugs of penthotal, lidocaine, saline, ketamine, ondansetron and decort by using wrist tourniquet. Then we evaluated arm withdrawn, grimace, verbal rating scale (VRS) and postoperative recall the pain during propofol injection. Results: Evaluation of VRS data between six groups revealed that the lidocaine group was the most painless group (86%). These findings were followed respectively by ondansetron (82%), decort (72%), penthotal (52%), ketamine (46%) and saline (12%). Conclusion: In this trail we revealed that lidocaine group was the most successful group to handle with propofol injection pain. Furthermore ondansetron group results were similar to lidocaine group.
