Effects of a Combination of IV-PCA With Continuous IV Infusion of MO, Versus IV-PCA MO on Postoperative Pain

Israel150 participantsStarted 2009-04

Plain-language summary

After major surgery, such as abdominal or thoracic surgery, the majority of patients experience moderate to severe pain that may not be optimally controlled. Inadequate pain relief may lead to complications that can hinder rehabilitation and slow recovery. Morphine (MO) is the most commonly used opioid for the treatment of post-surgical pain (14). The preferred method of administration nowadays is intravenous patient-controlled analgesia (PCA). In contrast, Continuous infusion of intravenous morphine (CIVM) is seldom used in Post-Anesthesia Care Units (PACUs) for acute postoperative pain, due to concerns of cardio-respiratory deterioration, even though different studies have found this technique of administration effective and safe (in terms of opioid-related symptoms.As part of our efforts to improve postoperative pain management in the Tel Aviv Sourasky Medical Center's PACU, we wish to determine if combining CIVM with IV PCA will be superior over IV PCA only for the treatment of postoperative pain following major abdominal or thoracic surgery.Our hypothesis is that the continuous infusion, even if given at a relatively low dose, would enable the build-up of pharmacologically effective MO blood level, thus providing an overall better control of pain.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * patients undergoing major abdominal procedures (e.g. laparotomy, nephrectomy, gastrectomy, gastric bypass, pancreatectomy, splenectomy, and abdominal aortic aneurysm) or thoracic surgery (segmentectomy, lobectomy or pneumonectomy) in our institution during the years 2008-9. Exclusion Criteria: * patients with a history of drug or alcohol abuse, psychiatric disturbances, senile dementia, Alzheimer's disease, seizures or suicide risk, use of psychotropic drugs, pregnancy or nursing, hypersensitivity to MO, or to non steroidal anti-inflammatory drugs (NSAIDs) or their excipients, chronic or acute pain of any origin, respiratory failure or insufficiency, uncompensated or congestive heart or hepatic failure and those scheduled for an emergency or palliative procedure. * we will also exclude patients using antidepressants, anticonvulsants or muscle relaxants, and patients using any monoamine oxidase inhibitor within 2 weeks of surgery.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
