Comparing Stress and Antioxidant Levels in Two Types of Anesthesia for Tubal Ligation
This study compares stress hormones and body chemicals in women who get either spinal anesthesia (numbing the lower body) or general anesthesia (fully asleep) during a laparoscopic tubal ligation. The goal is to see which method causes less stress on the body.
AnkaraAges 18–45 - NCT05681572RecruitingPhase 3
Sedation before surgery to help kids feel better after anesthesia
This study tests whether giving a calming medicine before general anesthesia improves how children feel and experience anesthesia afterward. The goal is to see which pre-surgery approach works best and is comfortable for kids.
Montpellier, MontpellierAges 7–18 - NCT07275450Recruiting
Ultrasound-guided numbing vs general anesthesia for ear surgery

ZagazigAges 21–65 - NCT06747494Recruiting
Comparing general vs spinal anesthesia for hip or knee replacement
This study compares two types of anesthesia (general and spinal) for people having a total hip or knee replacement. The goal is to see which approach is better for recovery and overall outcomes.
Miami, FloridaAges 18 years+ - NCT06879600Recruiting
High-flow oxygen for emergency surgery patients with full stomachs
This trial tests if using high-flow oxygen through the nose before surgery helps patients who need emergency surgery and have a full stomach. It may make oxygen levels safer during the start of anesthesia.
Viet Tri, Phu ThoAges 18 years+ - NCT06802224RecruitingPhase 4
Medication to prevent kidney injury after major surgery
This study compares two medications given during surgery to see which one better protects the kidneys after the procedure. If you are having major non-cardiac surgery that lasts at least 2 hours and you need medication to support your blood pressure, this trial may be a good fit.
San Francisco, CaliforniaAges 18 years+ - NCT07675798Recruiting
Caudal block for reducing fistula after hypospadias repair
This study tests whether a numbing injection into the lower back (caudal block) reduces the risk of a leak or fistula after hypospadias repair surgery in young boys. It may help your child have fewer complications and a smoother recovery.
Diyarbakır, Eyalet/YerleşkeAges 6 months–5 years - NCT07245654Recruiting
Monitoring anesthesia depth in children during surgery start-up
This study tests a special monitoring device (CONOX) that tracks how deeply a child is asleep and their pain level during anesthesia. The goal is to see if it helps make anesthesia safer and more comfortable for kids having surgery.
BrnoAges 1–19 - 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 - NCT05951764Recruiting
Checking risk prediction for heart and brain conditions
This study builds or tests computer models that predict risk for heart (cardiovascular) and thinking/memory (neurocognitive) problems using information from people in the general population. It may help improve early detection and planning for care.
ParisAges 45 years+ - NCT06346158Recruiting
Predicting deep anesthesia from propofol levels
This study wants to see if we can predict the right amount of propofol (a sleep medicine) needed for deep anesthesia during surgery. It may help doctors give just the right dose for each person.
Montreal, QuebecAges 18 years+ - NCT06892795Enrolling by invitation
Predicting low body temperature during surgery in children
This study aims to predict which children might get too cold during surgery under general anesthesia lasting more than 30 minutes. It's trying to create a simple checklist to help doctors keep kids warm and safe.
Harbin, HeilongjiangAges Up to 15 years - NCT02975310Recruiting
In-clinic endoscopy surgery for chronic sinus polyps
This trial tests an in-clinic (not hospital) endoscopic procedure to remove nasal polyps in people with chronic sinus inflammation, after usual medicines haven’t helped. It may help reduce nasal blockage and improve sinus symptoms, while comparing safety and outcomes after the procedure.
Vancouver, British ColumbiaAges 18 years+ - NCT06740201RecruitingPhase 4
Testing a new anesthesia drug in elective surgery
This study tests how well a computer model predicts the dose of a new anesthetic called cipepofol during planned surgeries that last at least an hour. The goal is to see if the model gives the right amount of drug for safe and effective anesthesia.
Chengde, HebeiAges 18–65 - NCT06296173Recruiting
Lung-protective breathing tube removal after surgery
This study tests a special breathing tube removal method during surgery recovery to protect your lungs. It may help you breathe better after your abdominal surgery.
Vancouver, British ColumbiaAges 18 years+ - NCT06906263Recruiting
Anesthesia safety during airway scopes in children with tracheostomy
This study looks at problems that may happen during anesthesia (medicine to put you to sleep) when children with a tracheostomy have a routine scope to check their airway. It aims to make these procedures safer for kids like you.
SolnaAges Up to 18 years - NCT06192082Recruiting
Heart risks during painless stomach scope in frail elderly
This study looks at whether older, frail patients have heart problems during a painless stomach scope (gastroscopy). It aims to find safer ways to give sedation for these patients.

Study brain signals after median nerve stimulation during anesthesia
This early-stage study checks how brain activity changes when the median nerve is gently stimulated while you’re under general anesthesia with propofol. It may help researchers better understand brain–nerve connections and improve how these signals are measured.
BrusselsAges 18–81 - NCT07275983Recruiting
Knee replacement recovery: spinal vs. general anesthesia
This study looks at recovery after total knee replacement surgery. It compares people who had spinal anesthesia (numbing the lower body) to those who had general anesthesia (being fully asleep) to see which group recovers better.

Common questions
- Are there clinical trials for general anesthesia?
- Yes. Clin2 currently lists 171 recruiting general anesthesia 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 anesthesia 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 anesthesia 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.
