Melbourne, VictoriaAges 6–18 - NCT06575738RecruitingPhase 1
Semaglutide for teens after weight-loss surgery
This study looks at how teenagers and young adults respond to weight-loss surgery (sleeve gastrectomy) and whether adding a medication called semaglutide can help improve weight loss. It has two parts: first observing how surgery affects you, then testing if semaglutide helps those who didn't lose enough weight after surgery.
Aurora, ColoradoAges 12–24 - NCT07519109RecruitingPhase 1
SYH9089 for pain after abdominal surgery
This study tests an injected medicine (SYH9089) to see if it safely controls pain after abdominal surgery. It may help you recover with less discomfort.
Changsha, HunanAges 18–75 - NCT07632664Recruiting
New treatment model for older lung cancer surgery patients
This study tests a new approach to help older adults (65+) with early-stage lung cancer who are candidates for surgery. The goal is to improve outcomes by using a special assessment to understand each patient's overall health before and after the operation.
Beijing, Beijing MunicipalityAges 65 years+ - NCT03124303Recruiting
Testing ways to measure and prevent delirium after surgery
This study looks at interventions to help with “postoperative delirium,” a sudden confusion that can happen after surgery, and uses brain measures like EEG and optional MRI. It may help doctors identify who is at risk and learn what approaches are most helpful after surgery.
Madison, WisconsinAges 60 years+ - NCT03230565RecruitingPhase 4
Continuous vs bolus pain medication through nerve catheter
This study compares two ways of delivering numbing pain medicine through a nerve catheter after surgery: a steady infusion versus scheduled bolus doses. It aims to see which method works better and is easier to use for post-operative pain control.
Stanford, CaliforniaAges 18 years+ - NCT03309384Recruiting
Monitoring during thyroid surgery to help predict complications
This study checks whether special monitoring done during thyroid surgery can help predict complications afterward. If you’re having a full (total) thyroidectomy, your team may use monitoring to better anticipate problems after surgery.
Vandœuvre-lès-NancyAges Any age - NCT03596424Recruiting
Testing ketamine and dexmedetomidine during lung surgery
This trial studies whether the anesthesia medicines ketamine and dexmedetomidine can improve care during elective lung (video-assisted) surgery. It may help with comfort during and after the operation, depending on how these medicines affect pain and recovery.
Montreal, QuebecAges 18–80 - NCT03625011RecruitingPhase 4
Gabapentin before tonsil surgery to reduce pain
This trial tests whether giving gabapentin before pediatric tonsil (and possibly adenoid) removal can reduce postoperative pain. It may help children feel more comfortable after surgery while still being safe to use in the right patients.
Atlanta, GeorgiaAges 3–18 - NCT03675386Recruiting
Help reducing opioid use after surgery for chronic pain
This trial tests a program to help people with long-term (chronic) pain use less opioid medicine after surgery. It may help you reduce opioid doses while still managing your pain.
Toronto, OntarioAges 18 years+ - NCT03715517Recruiting
Spinal anesthesia to improve recovery after liver surgery
This trial studies whether using spinal/epidural anesthesia during liver tumor removal surgery can help people recover better and with less pain. It compares this approach to standard general anesthesia care to see if recovery is smoother.
Winnipeg, ManitobaAges 18 years+ - NCT03737292RecruitingPhase 4
Numbing medicine for chest surgery pain after small lung operations
This trial tests whether a long-lasting numbing shot (liposomal bupivacaine) works better than a regular numbing shot (plain bupivacaine) for pain after minimally invasive chest surgery. It may help you have less post-surgery pain and potentially use less pain medication.
Hershey, PennsylvaniaAges 18 years+ - NCT03745534Recruiting
Cochlear implant after Gamma Knife for vestibular schwannoma
This pilot study looks at how well cochlear implants work for hearing restoration in people who previously received Gamma Knife treatment for a tumor called vestibular schwannoma. It may help doctors understand what hearing results to expect after surgery.
Vienna, State of ViennaAges 18 years+ - NCT03756961Recruiting
Opioid-free care plan for people having weight-loss surgery
This trial studies whether an opioid-free or opioid-sparing care pathway can improve comfort and outcomes for adults undergoing laparoscopic weight-loss surgery. It may help people avoid side effects from opioid pain medicines while still managing pain safely.
Lindesberg, Region ÖrebroAges 18 years+ - NCT03810768Recruiting
Metabolomics study of ICU-acquired weakness after surgery
This study looks at blood and body chemistry (called metabolomics) to understand and possibly predict muscle weakness that can happen in the ICU after surgery. It may help researchers find better ways to prevent or monitor this problem.
