Antinociceptive Modalities on Ischemia Reperfusion Injury

Taiwan142 participantsStarted 2011-01

Plain-language summary

Postoperative pain caused by surgery-associated tissue injury is a major concern for all the clinical practitioners. Because it affects multiple systems and induces physiological, immunological and psychological changes. Previous literature showed surgical injury induces a systemic inflammatory metabolic-endocrine response that is proportional to the severity of the surgical stress. In surgeries such as liver transplantation, the patients suffer not only from postoperative pain but also an additional oxidative stress caused by ischemia reperfusion. Previous report have proved that an adequate postoperative pain control improves the recovery and reduces the inflammatory cascade by suppression of physiological and psychological stresses. However, the effect of postoperative pain management on ischemia reperfusion injury is unclear so far. In this three year study, we plan to continue our previous study to test the following two hypothesis: (1) postoperative pain exacerbate remote organ injury caused by ischemia reperfusion, (2) the interaction of different antinociceptive modalities on ischemia reperfusion injury.

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?
