Effect of Rectus Block Timing on Opioid Use
Turkey (Türkiye)50 participantsStarted 2026-03-15
Plain-language summary
The aim of this study is to observe the effect of administering local anesthetic to the abdominal wall at the beginning or end of surgery under general anesthesia on opioid consumption during surgery. The hypothesis of this study is to demonstrate that administering a rectus sheath block before the surgical procedure under general anesthesia is effective in reducing intraoperative opioid consumption and opioid-related side effects compared to administering it after the surgery is completed.

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.
1This trial studied something called a 'rectus block' given at different times during prostate cancer surgery — is a rectus block a technique that would be considered for my surgery, and how does the timing of it affect pain control during the procedure?
2The study measured opioid use during surgery using a tool called the Nociception Level Index — can you explain what that monitoring approach involves, and whether that kind of real-time pain tracking is used in my surgical team's practice?
3Since this trial is now completed, have the results been published or shared anywhere, and if so, what did they find about whether earlier or later block timing reduced the amount of remifentanil needed during surgery?
4Remifentanil is a strong opioid used during surgery — how does reducing the amount of it used intraoperatively actually benefit me as a patient in terms of recovery or side effects after the operation?
5Given that this study is listed as Phase NA and focused specifically on intraoperative opioid consumption, does it tell us anything meaningful about post-surgical pain management, or should I be asking separate questions about pain control after I wake up from surgery?

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?
