Adjunctive Nitrous Oxide During Emergency Department Propofol Sedation in Adults
United States43 participantsStarted 2015-02
Plain-language summary
The purpose of this study is to describe the safety and efficacy of nitrous oxide administration for pain and anxiety before propofol in patients requiring any procedure under sedation in the Emergency Department. Procedural sedation is the use of sedative, analgesic, and/or dissociative agents to relieve anxiety and pain associated with diagnostic and therapeutic procedures. Propofol is commonly used and is a sedative and amnestic, but provides no analgesia. Short acting opioids may be used for pain relief, but come with the risk of respiratory depression. An optimum analgesic to relieve pain in patients who need procedural sedation should be short acting, easy to administer and safe. Nitrous oxide may be a suitable agent, but literature supporting or rejecting its use in adults is lacking. This study aims to fill this gap. Adult patients capable of consenting, coming to the Emergency Department with painful condition requiring procedural sedation are the targeted population. Eligible patients who consent to the study will receive Nitrous Oxide gas delivered through a hand held mask before they receive propofol for the procedure. Information regarding their vitals, pain scores and medical condition will also be collected.

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?

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?
