Pak J Med Health Sci Jan ;14(2):343-5.

Aim: To determine whether the pretreatment with thiopental sodium 0,5mg is better than lidocaine 40mg to prevent the pain associated with propofol injection. Study Design: Randomized control trial. Place & Duration: Department of Anesthesiology, Central Park Medical College and Hospital Lahore from 1st January 2019 to 30th June 2019. Methods: One hundred cases of ASA I-II aged 18-20 years old for elective surgery under general anesthesia were included. They were divided in two groups; group A and group B, each comprised 50 patients. At the time of induction of general anesthesia, group A was pretreated with injection thiopental sodium 0,5mg /kg and group B was with injection lidocaine 40mg after applying the tourniquet. All study drugs were made into 2ml with normal saline. The patient were observed and asked for pain after every 5-10 sec during the induction of propofol injection. Results: Patients in group A reported a significantly less pain as compared to group B. Conclusion: Using the thiopental sodium 0,5mg/kg before induction with propofol injection is better and safe to prevent the pain caused by propofol injection is better than lidocaine 40mg in elective surgery.
