Guangzhou, GuangdongAges birth+ - NCT04077762Recruiting
Radial vs femoral access to reduce bleeding in heart procedures
This study compares two ways doctors can reach the heart during a catheter procedure: through the wrist (radial) or the groin (femoral). It aims to reduce bleeding and access-site complications, especially when patients may need a balloon/stent (PCI).
San Francisco, CaliforniaAges 18 years+ - NCT04079361Recruiting
Testing early pregnancy complications in multiple languages
This study tests how early pregnancy complications are identified and managed. You may be able to participate if you can follow the study instructions and understand the consent information in the approved languages.
GhentAges 18 years+ - NCT04256798RecruitingPhase 3
Respiratory care after high-risk abdominal surgery
This trial looks at a breathing-focused care plan given around the time of major abdominal surgery to improve recovery and outcomes. You may be eligible if you’re having a large midline abdominal incision and can be followed after surgery.
Botucatu, São PauloAges 10–100 - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.
Fürth, BavariaAges 18 years+ - NCT04367987Recruiting
Heart Rate Changes After Colorectal Surgery
This study measures how your heart rate varies after planned colorectal surgery to see if these changes can predict complications. Researchers will monitor your heart rhythm before and after your operation to understand whether certain patterns might warn of problems early.
NîmesAges 18 years+ - NCT04446832Recruiting
Vaccine study for people waiting for liver transplant
This study tests a vaccine strategy for people who are being evaluated and waiting for a liver transplant. The goal is to see how well the immune system responds and how the results are interpreted before transplant.
LyonAges 18 years+ - NCT04498598Recruiting
Test a modified breathing device for the voice box area
This study tests a modified supraglottic airway device (a type of breathing aid placed above the vocal cords) during surgeries done under general anesthesia. It may help researchers see if a better-shaped device works more safely during planned surgeries that use muscle relaxation.
Cleveland, OhioAges 18–100 - NCT04529629Recruiting
Tests and tracks treatment for adrenal hormone tumor diseases
This trial studies how adrenal hormone tumor diseases should be diagnosed, treated, and followed over time. It may help people get more precise care and better prediction of outcomes, but it has specific health and medication requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04647968Recruiting
Testing one-step versus two-step closure of a trachea skin leak
This study compares two surgical ways to close an abnormal connection between your trachea (windpipe) and your skin (a tracheo-cutaneous fistula). It may help find the safer, more effective closure approach when you’re ready to remove your breathing tube.
Sherbrooke, QuebecAges 18 years+ - NCT04721041Recruiting
Fecal microbiota transplant for gut side effects after cancer treatment
This trial tests a treatment called “washed microbiota transplant,” which transfers healthy gut bacteria to help relieve intestinal problems that started after cancer therapy. You might benefit if you’re an adult with certain ongoing stomach or bowel symptoms after standard cancer treatment, and your body is stable enough for the procedure.
Nanjing, JiangsuAges 18 years+ - NCT04725916Recruiting
Study of water exposure and drain-related risks after certain surgeries
