Egypt100 participantsStarted 2023-03-01
Plain-language summary
This research will be carried out in order to determine the optimal lidocaine dose in propofol lidocaine mixture to prevent pain on propofol injection during induction of general anesthesia using a modified Dixon's up-and-down method. Patients \& methods: Include assessment of severity of pain on propofol injection using seven doses of lidocaine in lidocaine propofol mixture in ASA I\&II patients aged 18-60 years with exclusion of patients with history of drug allergy, hepatic or renal impairment, cardiac problems, neurologic deficits or psychiatric disorders.
The primary outcome will be pain scale during injection and volume of propofol-lidocaine mixture used. Secondary outcome will be increase in heart rate and/or hand or forearm withdrawal during injection, patient satisfaction, demographic data, type and duration of surgery, Time for unconsciousness.
Aim of the work: To determine the Minimal effective dose of lidocaine in propofol lidocaine mixture to achieve painless induction of anesthesia using propofol.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
