This trial tests whether spinal cord stimulation can reduce pain and improve quality of life in people with long-lasting nerve pain from chemotherapy (CIPN). You must already have tried at least two nerve-pain medicines and still have significant pain, and you must have had a successful spinal cord stimulator test before joining.
Rochester, MinnesotaAges 18 years+ - NCT05379673Recruiting
Breathing changes with extra oxygen after surgery
This study looks at whether giving extra oxygen during recovery from general anesthesia changes how you breathe after surgery. You may be offered different oxygen levels around the time you wake up to see what helps your breathing most comfortably.
Stanford, CaliforniaAges 18–70 - NCT05400174Recruiting
How blood pressure changes affect thinking and brain flow in Parkinson’s
This study measures how your blood pressure affects thinking skills and how blood flows in the brain in people with Parkinson’s. It may help researchers understand what blood-pressure changes could mean for cognition in Parkinson’s.
