ClinConnect Summary
This clinical trial is looking at how effective intravenous (IV) acetaminophen is for managing pain in patients who have a small bowel obstruction, compared to the usual treatment with opioid medications. A small bowel obstruction happens when something blocks the intestine, causing pain and preventing food and fluids from passing through. The study aims to see if using IV acetaminophen can provide better pain relief without some of the side effects that come with opioids.
To join this study, participants need to be adults aged 65 to 74 who have been diagnosed with a small bowel obstruction and are experiencing abdominal pain. They also need to be on a diet where they cannot eat or drink anything by mouth. However, certain individuals cannot participate, such as those with liver problems, those who are already on opioids, or anyone who cannot provide consent. If eligible, participants can expect to receive either the IV acetaminophen or the standard opioid treatment while their condition is being monitored closely. This trial is currently active but not recruiting new participants at this time.
