Testing a new way to predict numbing success for children's surgery
This trial checks if a simple monitor reading (peripheral perfusion index) can help doctors know if a numbing shot (caudal block) will work well for children having belly or pelvic surgery. It may lead to better pain control during and after surgery.
Cairo, AbbasiaAges 1–5 - NCT07359586Recruiting
Laryngopharyngeal injury after breathing tube under anesthesia
This study looks at throat and voice box injuries that can happen after having a breathing tube during surgery. It may help doctors understand why some people experience hoarseness, sore throat, cough, or choking after non-ear-nose-throat operations.
Hangzhou, ZhejiangAges Any age - NCT07330570Recruiting

This study looks at how likely children are to get new cavities after they have had dental treatment under general anesthesia for early childhood cavities. It aims to help dentists better understand and prevent future decay.
Aydin, AydınAges 6–16 - NCT07325812Recruiting
Lung opening maneuvers during spine surgery
This study tests whether periodic lung opening maneuvers during back surgery can reduce lung collapse and improve breathing mechanics. Doctors will use ultrasound to monitor your lungs.
IstanbulAges 18–65 - NCT07324863Recruiting
Ultrasound block for stress reduction in hernia surgery
This trial tests whether a specific ultrasound-guided nerve block (EXORA) can lower stress during umbilical hernia surgery. If you are having this surgery and are generally healthy, you may be able to join.
TantaAges 21–65 - NCT07308756RecruitingPhase 4
Study on two drugs for better recovery after surgery
This trial tests if giving two medicines, dexmedetomidine and esketamine, during and after surgery can help you feel better and recover more comfortably. It is for adults having general anesthesia for at least one hour who will use a patient-controlled pain pump afterward.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07301307Recruiting
Blood pressure and fluid management during surgery
This trial tests a new tool that helps doctors manage fluids and blood pressure during surgery. It uses a special index (HPI) and computer-assisted fluid management to keep your blood pressure stable, which may reduce complications.
Athens, AtticaAges 18 years+ - NCT07287293Recruiting
Suctioning vs no suctioning when waking from anesthesia
This trial compares two ways of managing your breathing tube when you wake up from general anesthesia: suctioning the tube or not. It aims to see which method is more comfortable and safer for you after surgery.
Samut SakhonAges 18 years+ - NCT06889987Recruiting
Pain block comparison for kidney surgery patients
This study compares two types of ultrasound-guided pain blocks for cancer patients having a kidney removed. It aims to find which block provides better pain control after surgery.
CairoAges 18–65 - NCT07244575Recruiting
Metformin and nausea after general anesthesia study
This study looks at whether the diabetes medicine metformin, taken before surgery, affects the risk of nausea and vomiting after general anesthesia. If you take metformin and are having planned surgery, this trial may help understand its effects.
Guangzhou, GuangdongAges 18 years+ - NCT06104059Recruiting
Pain management during planned laparoscopic surgery
This trial tests a new way to monitor pain during laparoscopic surgery. It may help your doctor adjust pain medicines to keep you comfortable.
Athens, AtticaAges 18–70 - NCT07224243Recruiting
How oxygen during surgery affects recovery
This study looks at how different oxygen levels during surgery affect recovery. It includes adults having surgery with a breathing tube, but excludes people having open-heart surgery, certain lung procedures, or who have had bleomycin chemotherapy.
Ann Arbor, MichiganAges 18 years+ - NCT06166706Recruiting
Ventilation methods in children during anesthesia
This study looks at how children are ventilated (helped to breathe) during surgery. It will help doctors understand current practices and improve care for young patients.
PerthAges Up to 16 years - NCT07203287RecruitingPhase 4
Comparing muscle relaxants in kidney disease patients during surgery
This trial compares two muscle relaxants, rocuronium and cisatracurium, to see which causes fewer complications in people with chronic kidney disease (not on dialysis) who need general anesthesia. If you have kidney disease and are having surgery that requires a breathing tube, this study may help determine the safer drug for you.
Galveston, TexasAges 18–80 - NCT07200726Recruiting
Brain inflammation and thinking after heart surgery
This study looks at whether brain inflammation during heart surgery may affect memory and thinking. It includes people aged 60 and older who are having planned heart surgery.
Genk, LimburgAges 60 years+ - NCT07165236Recruiting
Bladder tumor surgery and memory changes study
This study looks at how bladder tumor surgery might affect thinking and memory. It checks blood markers to see if they are linked to any mental changes after the operation.
Osijek, CroatiaAges 18–80 - NCT07143799Recruiting
Scalp block vs general anesthesia for subdural hematoma drainage
This study compares two ways to manage pain during surgery to drain a subdural hematoma (a collection of blood pressing on the brain). Some patients will get a scalp block (numbing injections in the head) while others will receive general anesthesia (being put to sleep). The goal is to see which approach works better and has fewer side effects.
SohagAges 18–75 - NCT07114549Recruiting
Validating a tool to predict difficult mask ventilation
This study tests whether a scoring system (MASCAN) can correctly predict if a patient will be difficult to ventilate using a facemask during surgery. It aims to improve safety by identifying high-risk patients before anesthesia begins.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT07108465RecruitingEarly Phase 1
Anesthetic comparison for wisdom tooth removal
This trial compares two numbing medicines, bupivacaine and ropivacaine, to see which works better for removing impacted lower wisdom teeth during general anesthesia. It may help determine which option provides better pain relief after surgery.
Porto Alegre, Rio Grande do SulAges 18–60 - NCT07088900Recruiting
Dexmedetomidine with bupivacaine for pain relief in children's appendix surgery
This trial tests if adding dexmedetomidine to bupivacaine (a numbing medicine given near the tailbone) provides better pain relief during and after appendix surgery in children. It may help reduce the need for other pain medicines.
CairoAges 2–7 - NCT06984874Recruiting
Nerve block for kids having chest surgery
This study tests a nerve block injection in the back to reduce pain in children aged 6–16 having a specific type of chest surgery (thoracoscopic sympathectomy). It may help them wake up more comfortable and need less pain medicine.
Shibīn al Kawm, MenoufiaAges 6–16 - NCT07061548Recruiting
Predicting heart output changes during surgery using capnography
This trial uses a computer algorithm to predict changes in how well your heart pumps blood during surgery. It looks at carbon dioxide levels in your breath to make these predictions. This could help doctors adjust care in real time.
SeoulAges 19–75 - NCT07027293Recruiting
Comparing two airway devices in elderly patients
This trial tests whether placing the I-gel or classic laryngeal mask airway in different head positions works better for elderly patients during surgery. It aims to find the safest way to help you breathe while you are asleep.

Common questions
- Are there clinical trials for general anesthesia?
- Yes. Clin2 currently lists 176 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.
