Recruiting studies
- NCT06802224RecruitingPhase 4
Medication to prevent kidney injury after major surgery

Comparing anesthesia types for hip surgery in older adults
This study compares general anesthesia (you are completely asleep) versus spinal anesthesia (you are awake but numb from the waist down) during hip surgery to see which one is better at preventing heart muscle damage. It is for people 65 and older who are at moderate to high risk for heart problems.
IstanbulAges 65 years+ - NCT05824338RecruitingEarly Phase 1
Testing ropivacaine spinal anesthesia for lower back surgery
This early study tests whether using ropivacaine (a local numbing medicine) in spinal anesthesia is safe and workable for certain lower back operations. If you qualify, it may help doctors refine anesthesia choices for your type of surgery.
New Westminster, British ColumbiaAges 19–80 - NCT06454305Recruiting
Breathing exercises after abdominal surgery
This study tests two breathing techniques (ACBT and blow bottle) to help people recover lung function after abdominal surgery under general anesthesia. If you have trouble coughing up mucus or need extra oxygen after surgery, you may benefit.
Lahore, Punjab ProvinceAges 30–50 - NCT07021105Enrolling by invitation
Comparing nerve blocks for pain after gynecological surgery
This study tests two different types of nerve blocks (called 'plain blocks') to see which one works better for controlling pain after major gynecological surgery. You would receive one of the blocks before surgery, and then use a pump you control to get extra pain medicine as needed.
Adana, SarıçamAges 18–69 - NCT06909227Recruiting
Testing lactate levels to predict complications after infant surgery
This study checks whether measuring lactate (a substance made by muscles during stress or low oxygen) in a vein right after surgery can help doctors predict complications in babies less than 1 year old. It focuses on infants who need general anesthesia for non-cardiac surgeries inside the hospital.
ParisAges birth–1 year - NCT07048899Enrolling by invitationPhase 4
Irrisept for emergency surgery patients
This trial tests if using Irrisept (a special wound-cleaning solution) during emergency surgery can help prevent infections. It includes adults who need an open surgery for an urgent stomach or bowel problem.
Tyler, TexasAges 18 years+ - NCT06417567Recruiting
Preventing nausea and vomiting after GI cancer surgery
This study tests whether the medication NEPA (Netupitant and Palonosetron) can prevent nausea and vomiting in people who have had surgery for liver, gallbladder, or pancreatic cancer. It may help those who want to avoid post-surgery sickness.
Tianjin, Tianjin MunicipalityAges 18–65 - NCT07064200Recruiting
Timing of TAP blocks for abdominal surgery
This study compares two different ways to give a numbing medicine (TAP block) before abdominal surgery to see which one works better for pain control. If you are scheduled for elective abdominal surgery, joining may help doctors find the best way to manage your pain.
New York, New YorkAges 18–65 - NCT04620343Recruiting
Study of breathing treatment for EILO during exercise
This trial tests a treatment approach for exercise-related breathing difficulty called EILO. It aims to help people whose breathing problems show up during peak exercise and who want ongoing follow-up.
Bergen, VestlandAges 12 years+ - NCT07461779RecruitingPhase 4
Oxygen to the healthy lung during lung surgery
This study is testing whether giving extra oxygen to the lung that is not being operated on (the non-dependent lung) during surgery can reduce problems after lung surgery. If you are having lung surgery, this might help you recover better.
MadridAges 18 years+ - NCT06400901Recruiting
Brain signals during recovery from anesthesia for DBS patients
This trial records brain activity during recovery from general anesthesia in people undergoing deep brain stimulation (DBS) surgery. It aims to understand how the brain wakes up after anesthesia.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07176494Recruiting
Revision of Deep Brain Stimulator in Parkinson's Disease
This study is for people with Parkinson's disease who need to have their deep brain stimulator (a device that sends electrical pulses to control movement) replaced or adjusted. The researchers want to learn the best way to do this procedure safely.
Ankara, Yenimahalle\AnkaraAges 40–85 - NCT07716891Recruiting
Testing if rocuronium given before anesthetic speeds up muscle relaxation onset
This trial investigates whether giving rocuronium (a muscle relaxant) before the main anesthetic can make muscles relax faster and affect heart rate and blood pressure during the start of general anesthesia. It aims to improve safety and smoothness of the process for people having planned surgery with a breathing tube.
YinchuanAges 18–65 - NCT06743243Enrolling by invitationPhase 4
Tegoprazan for planned surgery patients under general anesthesia
This trial tests whether a stomach-acid-reducing drug (tegoprazan) helps prevent complications during planned surgeries under general anesthesia. It is for adults aged 20–69 with a non-emergency surgery and a BMI under 35.
SeoulAges 20–69 - NCT06814054Recruiting
Predicting low blood pressure after anesthesia in older patients
This study uses ultrasound measurements of the carotid artery and vena cava to predict if older patients might experience low blood pressure after going under general anesthesia for elective surgery. If successful, it could help doctors take preventive steps.
Tanta, El GharbyiaAges 65 years+ - NCT06378645RecruitingPhase 4
Propofol vs. sevoflurane for erections during urologic surgery
This study compares two common anesthesia drugs, propofol and sevoflurane, to see which one helps prevent unwanted erections during urologic surgery. It is designed for people having transurethral procedures (like for an enlarged prostate or bladder tumor) who have at least mild erectile function.
ZurichAges 18–75 - NCT05608772Recruiting
Revision weight-loss surgery after failed sleeve
This study looks at which revision surgery works best after a prior sleeve stomach operation that didn’t last. It tests switching to one of three procedures to help with weight regain, and it excludes more severe acid reflux cases.
Alexandria, Alexandria GovernorateAges 18–60 - NCT07501468Recruiting
Comparing two breathing devices for shoulder surgery
This trial tests two types of breathing tubes (SafeLM and I-gel) to see which works better for people having shoulder surgery while sitting up. It aims to find a safer way to keep your airway open during the procedure.
Ankara, AnkaraAges 18–80 - NCT07746505Recruiting
Remimazolam vs midazolam for anesthesia in older adults
This study compares two sedative medicines used to start general anesthesia in patients 65 and older having non-cardiac surgery. The goal is to see which one is safer and works better for older patients.
HangzhouAges 65 years+ - NCT06380244Recruiting
Pain Relief Without Opioids for Abdominal Surgery
This study tests if a completely opioid-free anesthesia approach works as well as standard general anesthesia for people having laparoscopic or robotic urological surgery. It aims to offer effective pain control without using strong opioid painkillers.
Krakow, Lesser Poland VoivodeshipAges 18–75 - NCT07280546Recruiting
Breath sounds study during surgery
This trial studies breath sounds during planned surgeries under general anesthesia. It aims to understand how breath sounds change during procedures, which may help doctors improve monitoring and care.

- Are there clinical trials for general surgery?
- Yes. Clin2 currently lists 123 recruiting general surgery 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 general surgery 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 general surgery 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.
