Opioid-free anaesthesia for reducing confusion after stomach surgery in older adults
Treatments studied
Part of Brain & nervous system, Mental health clinical trials.
This study tests whether avoiding opioid painkillers during anaesthesia can reduce confusion after surgery in older adults. It is specifically for people 65 and older having stomach or intestine surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 65 years old or older.
- You must be scheduled for non-emergency gastrointestinal surgery (surgery on your stomach or intestines) with general anaesthesia.
- Your body mass index (BMI) must be between 18 and 30. Your doctor can tell you this number.

- You must not have taken certain psychiatric medications long-term, like clozapine, risperidone, or haloperidol, within the past year.

This study tests whether a low dose of the medicine esketamine can help prevent confusion after surgery in older adults at higher risk. You may qualify if you are 65 or older, planning a major non-cardiac surgery, and have certain health conditions like high blood pressure or diabetes.
This study tests whether avoiding opioid pain medicines during surgery can lower the chance of confusion or delirium after the operation. It is for adults aged 65 or older who are having planned abdominal surgery.
This study compares two types of anesthesia for older adults having major planned surgeries. One type avoids using opioid painkillers (which can cause side effects), and the other includes them. The goal is to see if avoiding opioids helps you feel better and recover more comfortably after your operation.
This trial tests giving either lidocaine or dexmedetomidine during abdominal surgery to see if it helps keep the brain healthy and lowers the chance of waking up confused or agitated. It is for older adults having planned abdominal surgery who are otherwise in fairly good health.
This study is looking at a pain management approach that avoids using opioid painkillers during heart surgery in older adults. The goal is to see if this approach helps people recover faster after surgery with fewer side effects.
This study tests whether a nasal spray called dexmedetomidine can help prevent confusion (delirium) after lung surgery in people aged 65 and older. It is given before surgery to see if it keeps the mind clear during recovery.
