Reducing anxiety for children before surgery
This study tests a way to help children aged 5-12 feel less anxious before surgery. If successful, it could make the start of anesthesia calmer and more comfortable for your child.
MarseilleAges 5–12 - NCT06957678Enrolling by invitation
AI predicts lymph node spread in stomach cancer using scans and biopsy
This study uses artificial intelligence to predict whether stomach cancer has spread to nearby lymph nodes. By analyzing your CT/MRI scans and biopsy results before surgery, the AI may help doctors plan your treatment more precisely.
Shijiazhuang, None SelectedAges 18–80 - NCT05702944RecruitingPhase 4
Skipping pre-surgery blood pressure medicine for certain adrenal tumors
This trial studies whether it is safe to skip a specific pre-surgery blood pressure medicine (alpha-blocker) for people with normal blood pressure who have a pheochromocytoma or paraganglioma in one adrenal gland. It aims to see if fewer pre-op meds can still prevent risky blood pressure surges during surgery.
SeoulAges 19–70 - NCT06947096Enrolling by invitation
AI prediction of stomach cancer spread to lymph nodes
This study uses artificial intelligence to analyze your CT scan and predict whether stomach cancer has spread to lymph nodes behind your belly. The goal is to help doctors decide if you need more extensive surgery.
Shijiazhuang, None SelectedAges 18–80 - NCT06933498Recruiting
Nerve block for less pain meds in back surgery
This trial tests whether a nerve block (called an erector spinae plane block) given before surgery can reduce the amount of pain medicine and anesthesia needed during lumbar disc surgery. It may help people have less pain and fewer side effects.
AnkaraAges 18–75 - NCT06937853Recruiting
Genes and painkiller response for tooth pain
This trial tests whether your genes affect how well a common painkiller (NSAID) works for tooth pain after a root canal procedure. It may help find the best pain relief for you.
Erzurum, ErzurumAges 18–65 - NCT06906601Recruiting
Magnetic tracking before breast surgery: a medical study
This study tests a new magnetic tracking method to help surgeons precisely locate breast tumors before surgery. It may help improve the accuracy of breast-conserving surgery.
LyonAges 18 years+ - NCT06905132RecruitingPhase 2
Short radiation before surgery for soft tissue sarcoma
This study tests a 5-day course of radiation before surgery instead of the usual 5 weeks. It may help people who face challenges like travel or tumor growth that make the longer schedule difficult.
Charleston, South CarolinaAges 18 years+ - NCT06421285Recruiting
Exercise before breast cancer surgery to prevent lymphedema
This trial tests whether doing exercise before surgery can help prevent arm swelling (lymphedema) in women being treated for breast cancer. If you are newly diagnosed, facing chemotherapy first, and can exercise safely, this study might be a good fit.
Seoul, Seoul Special CityAges 20–80 - NCT06889545Recruiting
Comparing ways to measure frailty before surgery in older adults
This trial compares different ways to measure frailty in people aged 70+ before surgery lasting at least 2 hours, to see which tool works best.
HamburgAges 70 years+ - NCT06560905RecruitingPhase 2
PSMA-PET scan before melanoma surgery
This trial tests if a special scan (PSMA-PET) can help plan surgery for melanoma that has spread to lymph nodes. It may help doctors remove all cancer more accurately.
LondonAges 18 years+ - NCT05146726Recruiting
Finding the best care for low blood before planned surgery
This study looks at how to detect and treat pre-surgery anemia (low hemoglobin/low blood level) in people having planned operations where blood transfusion is likely. Some participants may also use a machine that collects and returns their own blood during surgery to reduce the need for donor blood.
BerlinAges 18 years+ - NCT05141591Recruiting
Anxiety before ENT surgery and opioid use after surgery
This trial looks at whether people’s anxiety before ear, nose, and throat (ENT) surgery affects how much pain medicine (opioids) they need after surgery. It may help doctors better plan pain control based on anxiety level and possibly gender-related patterns.
Vienna, State of ViennaAges 18 years+ - NCT06857630Recruiting
Hemoglobin levels and kidney injury in emergency surgery
This trial looks at whether a patient's hemoglobin level (a measure of red blood cells) before emergency surgery can help predict the risk of acute kidney injury afterward. It aims to find if early detection can prevent kidney damage.
SamsunAges 18–80 - NCT06824935Enrolling by invitation
Cataract surgery anesthesia needs study
This study looks at how much anesthesia is needed during outpatient cataract surgery. It may help find the right approach for your comfort and safety.
IstanbulAges 18 years+ - NCT06818942Recruiting
Predicting difficult keyhole appendix surgery
This trial looks at how to predict if a laparoscopic appendectomy (keyhole surgery to remove the appendix) will be more difficult. It uses information from before surgery to help doctors and patients prepare.
Shanghai, Shanghai MunicipalityAges Any age - NCT06810232Enrolling by invitation
Health factors and longer hospital stay after endoscopy
This study looks at how general health factors (like age and other medical conditions) might affect how long you need to stay in the hospital after a routine stomach or bowel exam called an endoscopy. The goal is to understand which patients may need extra care so hospitals can plan better.
IstanbulAges 18 years+ - NCT06806059Recruiting
Exercise before bladder removal surgery study
This study looks at whether being active before bladder cancer surgery helps you recover with fewer problems. It tests how physical activity before surgery affects your health afterwards.
Munich, BavariaAges 18 years+ - NCT06808022Enrolling by invitation
Back exercises before spine surgery

La Jolla, CaliforniaAges 18 years+ - NCT06805721Recruiting
Observational study of endovascular treatment for brain and spine vessel conditions
This study follows patients of any age who are having a minimally invasive procedure (endovascular treatment) for blood vessel problems in the brain or spine. It looks at how patients do before and after the procedure, any complications, and what factors might predict a good outcome.
MilanAges Any age - NCT06794697Recruiting
Does admission day affect anxiety before heart surgery?

Common questions
- Are there clinical trials for preoperative?
- Yes. Clin2 currently lists 376 recruiting preoperative studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a preoperative trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a preoperative trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
