Chicago, IllinoisAges 19 years+ - NCT04355195Recruiting
Preventing delirium after surgery in older patients
This trial tests a “care plan” meant to lower the risk of confusion (delirium) after surgery in people age 70 and older. If you qualify, you may receive additional prevention-focused care before and around your operation.
BerlinAges 70 years+ - NCT04194216Enrolling by invitationPhase 3
Antibiotic prevention during rhinoplasty surgery
This trial studies whether giving antibiotics before and around rhinoplasty (nose reshaping) can lower the risk of infection. If you qualify, you may be randomized to receive antibiotic prevention or another approach to prevention.
Stanford, CaliforniaAges 18 years+ - NCT04109638Recruiting
PEMF therapy to reduce pain after shoulder or knee surgery
This trial studies whether PEMF, a type of non-surgical device that uses pulsed electromagnetic fields, can reduce pain after shoulder or knee surgery. If you join, you’ll also be expected to do post-surgery physical therapy exercises and report your pain and function.
Redwood City, CaliforniaAges 18 years+ - NCT04134702Recruiting
Acupuncture for less pain after outpatient knee surgery
This study tests whether acupuncture can reduce pain after outpatient arthroscopic knee surgery done under general anesthesia. It may help by improving pain control while avoiding certain medicine side effects, but you must meet several specific safety and medication limits.
Greifswald, VorpommernAges 19–55 - NCT04094701Recruiting
Study of opioid needs after hip arthroscopy surgery
This study looks at how much pain medicine (opioids) people actually need after hip arthroscopy and what factors may affect it. It may help improve safer, more personalized pain control after surgery.
Chicago, IllinoisAges 18–80 - NCT04144972Recruiting
Closed-loop deep brain stimulation for long-lasting nerve pain
This trial tests a “smart” deep brain stimulation device that senses your brain signals and adjusts treatment to reduce severe, long-lasting pain. It may help people whose pain has not improved with multiple pain medicines and surgery cannot fix the cause.
San Francisco, CaliforniaAges 22–80 - NCT03810768Recruiting
Metabolomics study of ICU-acquired weakness after surgery
This study looks at blood and body chemistry (called metabolomics) to understand and possibly predict muscle weakness that can happen in the ICU after surgery. It may help researchers find better ways to prevent or monitor this problem.
Vienna, State of ViennaAges 18 years+ - NCT03737292RecruitingPhase 4
Numbing medicine for chest surgery pain after small lung operations
This trial tests whether a long-lasting numbing shot (liposomal bupivacaine) works better than a regular numbing shot (plain bupivacaine) for pain after minimally invasive chest surgery. It may help you have less post-surgery pain and potentially use less pain medication.
Hershey, PennsylvaniaAges 18 years+ - NCT03857945Recruiting
Training to prevent falls after foot or ankle surgery
This trial studies whether teaching people to use mobility devices before surgery can lower the chance of falling afterward. It’s for adults having planned (elective) one-sided foot or ankle surgery and who will need limited walking after surgery.
Birmingham, AlabamaAges 18 years+ - NCT03875716Recruiting
De-intensified radiation after surgery for HPV throat cancer
This trial studies a lower-intensity (less aggressive) course of radiation therapy after curative surgery for HPV-related tonsil or base-of-tongue cancer. The goal is to see if patients can still be treated successfully while reducing side effects from radiation.
Boston, MassachusettsAges 18 years+ - NCT03675386Recruiting
Help reducing opioid use after surgery for chronic pain
This trial tests a program to help people with long-term (chronic) pain use less opioid medicine after surgery. It may help you reduce opioid doses while still managing your pain.
Toronto, OntarioAges 18 years+ - NCT03715517Recruiting
Spinal anesthesia to improve recovery after liver surgery
This trial studies whether using spinal/epidural anesthesia during liver tumor removal surgery can help people recover better and with less pain. It compares this approach to standard general anesthesia care to see if recovery is smoother.
Winnipeg, ManitobaAges 18 years+ - NCT02939664Enrolling by invitation
Laparoscopic gastric bypass vs banding for weight loss
This trial compares two types of minimally invasive weight-loss surgery: gastric bypass versus a gastric band. It looks at which approach works better and is safer for people who qualify for bariatric surgery and have not succeeded with supervised weight-loss programs.
Majadahonda, MadridAges 18–65 - NCT02083835Recruiting
Study to improve pain after surgery using patient questionnaires
This trial studies how to better understand and improve pain after surgery by asking patients to complete short questionnaires. It may help hospitals find ways to reduce postoperative pain and better track recovery.
JenaAges 4 years+ - NCT00969111Recruiting
Radiation after prostate surgery for prostate cancer without nodal spread
