TaoyuanAges 18 years+ - NCT05843877RecruitingPhase 3
Surgery choice and insulin islet transplant to prevent leaks
This Phase 3 trial studies a pancreatic surgery approach (pylorus-preserving Whipple or similar) and, in some cases, moving your insulin-making cells into your body to help prevent a dangerous post-surgery leak from the pancreas. It may help people who are considered high risk for this complication based on pancreas texture and duct size.
DresdenAges 18 years+ - NCT05824260Recruiting
Study of risk factors for complications after major surgery
This study looks at patients who've had major abdominal, bone, or blood-vessel surgery to understand what factors make some people more likely to have complications afterward. It analyzes information already collected from hospitals to help doctors better predict and prevent problems.
AmiensAges 18 years+ - NCT05789953Recruiting
Machine-learning plan to prevent lung complications after surgery
This trial tests a computer-based (machine-learning) approach to help prevent lung problems after elective surgery done under general anesthesia. It may help by identifying higher-risk patients and guiding care to reduce postoperative pulmonary complications.
UlmAges 18 years+ - NCT05794321RecruitingPhase 2
IV tranexamic acid during gender-affirming chest surgery
This Phase 2 study tests whether giving tranexamic acid through a vein during gender-affirming mastectomy can safely reduce bleeding. It may help lower blood loss and related complications during surgery.
San Francisco, CaliforniaAges 18 years+ - NCT05133024RecruitingPhase 2
Beetroot juice to help prevent bowel slowdown after colon surgery
This Phase 2 study tests whether drinking beetroot juice can reduce “postoperative ileus,” when the intestines temporarily don’t move normally after colorectal surgery. If it works, it may help you recover bowel function sooner after an elective laparoscopic colon and upper rectum operation.
EdegemAges 18 years+ - NCT05124236Recruiting
Pre-surgery vs post-surgery focused radiation for brain metastases
This trial compares two ways of giving focused radiation for brain metastases: before surgery or after surgery. It aims to see which timing works better to control tumors while keeping you safe.
InnsbruckAges 18 years+ - NCT04908579RecruitingPhase 4
Preventive ketamine to reduce pain after surgery
This study tests whether giving ketamine before or during surgery can reduce pain afterward. It is designed for adults with higher body weight who also have certain health conditions like well-controlled diabetes or blood pressure.
CairoAges 21–60 - NCT04912531Recruiting
Virtual reality and smell tools to ease surgery pain
This trial tests whether a combination of virtual reality and guided smells can reduce pain and anxiety around major heart and chest surgeries. If you’re scheduled for one of the listed operations, the study may help make recovery feel more comfortable by using sensory-based distraction.
Boston, MassachusettsAges 18 years+ - NCT03489499Recruiting
Genetic testing study of pain after planned surgery
This study looks at whether genetic differences can help predict how much pain you may have after an elective (planned) operation. If you qualify, you may be asked to give consent and share information so researchers can compare pain experiences across people.
BernAges 18 years+ - NCT04828954Recruiting
Testing different immobilization plans after thumb joint surgery
This study compares different ways of keeping your thumb still (immobilizing it) after thumb base joint surgery. It aims to see which immobilization approach leads to better recovery and hand function.
Chicago, IllinoisAges 40 years+ - NCT04707794Recruiting
Preventing confusion after non-heart surgery in older adults
This study looks at how often older adults develop sudden confusion (delirium) after non-heart operations under general anesthesia. It may help doctors better predict who is at risk and improve care after surgery.
New Delhi, National Capital Territory of DelhiAges 65 years+ - NCT04725916Recruiting
Study of water exposure and drain-related risks after certain surgeries
This trial looks at how using water (like showers) affects risks related to surgical drains after specific cosmetic or reconstructive procedures. Your results may help improve post-surgery safety guidance for patients who go home with drains.
Danville, PennsylvaniaAges 18 years+ - NCT04433676Recruiting
