How blood sugar control affects brain oxygen and recovery in diabetic surgery patients
This study looks at how well-controlled blood sugar (measured by HbA1c) affects brain oxygen levels during urologic surgery and how it impacts recovery afterward. It compares diabetic patients to non-diabetic patients to understand the role of blood sugar control in surgical outcomes.

Comparing opioid-free to standard anesthesia for back surgery
This study compares two types of anesthesia for lower back surgery: one that uses opioids and one that does not. The goal is to see which approach controls pain better with fewer side effects.
Istanbul, MaltepeAges 18–75 - NCT07483151Recruiting
Heart Surgery and Thinking Changes Study
This study looks at how changes in blood flow (called venous congestion) after heart surgery might affect thinking and memory. It aims to find out if there is a link between how blood returns to the heart and brain function after surgery.
Yangzhou, JiangsuAges 18 years+ - NCT06776536Recruiting
Testing ultrasound depth in endometriosis bowel surgery
This trial uses an ultrasound probe placed inside the rectum during surgery to see how accurately it measures how deep and how far endometriosis has spread into the bowel wall. The goal is to help surgeons decide exactly how much bowel needs to be removed.
IstanbulAges 18–55 - NCT07472959RecruitingPhase 4
Morphine for pain after heart bypass surgery
This study tests whether giving morphine during coronary artery bypass surgery can help control pain after the operation. It is for people having planned heart bypass surgery who are moderately sick and not already on strong pain medicines.

Shared decision-making during planned C-section under spinal anesthesia
This trial tests whether involving you in decisions during your planned C-section can improve your experience. You will be awake under spinal anesthesia and the study focuses on helping you feel more in control.
AlexandriaAges 18 years+ - NCT06393062Recruiting
Urine test after kidney stone surgery
This trial checks whether a simple test on the first urine after kidney stone surgery can help find infections early. It only includes adults having a specific type of stone removal who are infection-free before surgery.
AdıyamanAges 18 years+ - NCT07463586Recruiting
Brain oxygen and confusion after surgery in older adults
This study looks at how giving extra oxygen during surgery affects brain function and confusion (delirium) in older adults. It involves placing a small sensor on your forehead to measure brain oxygen levels.
Seongnam-si, Gyeonggi-doAges 65 years+ - NCT06791005RecruitingPhase 3
Timing of carbon nanoparticles injection for thyroid cancer
This trial tests whether the timing of a carbon nanoparticle injection during thyroid cancer surgery improves outcomes. It may help patients who need their whole thyroid removed and have cancer in both lobes or spread to lymph nodes.
Xi'an, ShaanxiAges 16–80 - NCT07460037Recruiting
Brain signal study for speech recovery after stroke or injury
This trial uses a special brain-mapping test called high-density ECoG to study how people who have lost speech due to stroke, brain tumor, or ALS can be helped by reading brain signals when they imagine speaking. It may lead to new devices that let people with severe speech problems communicate using only their thoughts.
Hangzhou, ZhejiangAges 20–80 - NCT06753500RecruitingPhase 4
Numbing medicine during gallbladder surgery
This trial tests whether giving a special numbing medicine during gallbladder surgery helps reduce pain. It is for adults having laparoscopic (minimally invasive) gallbladder removal.
Barranquilla, AtlantivoAges 18 years+ - NCT05150795RecruitingEarly Phase 1
Testing pregabalin before surgery versus fentanyl during surgery
This trial compares two medicines used around the time of surgery—pregabalin given by mouth before surgery versus fentanyl given during surgery—to see which better controls pain after the operation. You might join if you’re a generally healthy surgical patient and aren’t using certain related medicines.
CairoAges 21–45 - NCT07445659Recruiting
Brain-guided anesthesia for thyroid surgery
This study is testing a new type of brain-activity monitoring during thyroid surgery. It uses special stickers on your head to help guide the anesthesia, which may lead to a smoother recovery.
Kayseri, KayseriAges 18–70 - NCT06101511Recruiting
Breathing tube pressure for safer abdominal surgery
This trial is testing if using less air pressure from the breathing machine during abdominal surgery can help prevent lung complications. If you are at higher risk for breathing problems after surgery, this study may help find a safer way to manage your breathing during the operation.
Amsterdam, NoordhollandAges 18–100 - NCT07449897Recruiting
Gallstone removal during gallbladder surgery study
This study tests a method to remove bile duct stones during gallbladder surgery, aiming to treat both problems in one procedure.
OsloAges 18 years+ - NCT06804434Recruiting
Pain monitor during stomach or liver cancer surgery
This trial tests a device that monitors your pain level during surgery using a special index called the Nociception Level Index. It may help doctors manage your pain better without using too much medicine.
Cluj-Napoca, ClujAges 18 years+ - NCT07439679Recruiting
Anxiety Before Double Jaw Surgery and Your Recovery
This trial studies how anxiety before double jaw surgery affects your body during surgery and your recovery (pain, swelling, and ability to open your mouth). Researchers will use a simple anxiety questionnaire to see if feeling anxious changes your surgical experience.
IstanbulAges 18 years+ - NCT07440199Recruiting
Comparing two pain blocks for lung surgery without a breathing tube
This study compares two different pain-blocking techniques for a specific type of lung surgery. It aims to see which one provides better pain relief for patients who are awake during the procedure.
ElâzığAges 18–65 - NCT06808295RecruitingPhase 1
Dexmedetomidine for tear duct surgery
This study tests whether a medication called dexmedetomidine can reduce the amount of anesthesia needed during tear duct surgery (DCR), possibly making the procedure safer and more comfortable.
GizaAges 16–75 - NCT05831345RecruitingPhase 3
Methadone during surgery to prevent post-surgery pain
This Phase 3 trial tests whether giving methadone during hip or knee replacement surgery can reduce pain after surgery. It may help some people use less rescue pain medicine afterward, but it also has safety checks for kidney, liver, heart, and opioid-related risks.
BrusselsAges 18–80 - NCT07429916RecruitingEarly Phase 1
Ketamine for shoulder pain after weight loss surgery
This trial tests if a single dose of ketamine, given during surgery, can reduce common shoulder pain after laparoscopic gastric sleeve surgery. If you are having this weight-loss procedure and meet the weight and health criteria, this study may help improve your recovery.
