Recruiting studies
- NCT06666985RecruitingPhase 4
Spinal morphine for pain relief after major abdominal surgery
This trial tests whether a single injection of morphine into the fluid around the spine can provide better pain relief after planned laparoscopic or robotic abdominal surgery. If you are having one of several types of major abdominal surgery that lasts at least 2 hours and requires a hospital stay of at least 1 day, this study may be an option.

GothenburgAges Any age - NCT06247384Recruiting
Predicting low blood pressure during major abdominal surgery
This trial tests a tool that predicts drops in blood pressure during major abdominal surgery. It may help doctors manage blood pressure better during and after surgery.
Poznan, PoznańAges 18–80 - NCT07199881Recruiting
Breathing effort study after major abdominal surgery
This study checks how your breathing effort changes with different levels of breathing support from the ventilator after major abdominal surgery. It helps doctors find the best settings to help you breathe comfortably while you recover.
Bangkok, BangkoknoiAges 18 years+ - NCT07450950Recruiting
Learning from patients before and after major cancer surgery
This trial looks at how people understand health information and what they expect before and after major cancer surgery. The goal is to help doctors better support patients by learning about their hopes and possible regrets.
Copenhagen, CopenhagenAges 18 years+ - NCT07394816Recruiting
Can ultrasound-guided pain blocks reduce lung complications after abdominal surgery?
This study tests whether using ultrasound-guided pain blocks (fascial plane blocks) during major abdominal surgery can reduce lung complications after surgery, especially in older adults. It may offer better pain control and faster recovery.
Yenimahalle, AnkaraAges 65 years+ - NCT07273136Recruiting
Belly nerve block vs. epidural for pain after cancer surgery
This study compares two ways to manage pain after major abdominal cancer surgery: a numbing injection around the belly muscles (subcostal and lateral TAP block) versus an epidural (a thin tube placed in your back). The goal is to see which provides better pain relief.
AsyutAges 18 years+ - NCT07303855Recruiting
Better fluid management after major abdominal surgery
This study compares two ways of giving fluids to people after major abdominal surgery in the ICU. It will see if using a measure of how much blood the heart pumps (cardiac index) is better than the usual method based on vein pressure.
Jakarta Pusat, DKI JakartaAges 18–65 - NCT07331441Recruiting
Nerve block for pain relief after major upper abdominal surgery
This trial tests a nerve block given near the ribs to see if it reduces pain after surgeries like gastric, liver, gallbladder, or pancreatic surgery. It may help you need less pain medicine after the operation.
ShanghaiAges 18–85 - NCT07339449Recruiting
Monitoring during surgery to reduce time on a breathing tube
This study tests whether special monitors used during major abdominal surgery can help high-risk patients wake up sooner and need a breathing tube for less time after the operation.
Zagreb, CroatiaAges 50 years+ - NCT07510451Recruiting
Predicting low blood pressure during major aortic surgery
This trial tests a new monitoring tool that predicts drops in blood pressure before they happen during major aortic surgery. It may help doctors keep your blood pressure more stable during the procedure.
Poznan, PoznańAges 18 years+ - NCT07611721Recruiting
Testing a glucose monitor in critically ill surgery patients
This study tests whether a wearable glucose monitor (Dexcom G7) works well in patients in intensive care after major abdominal surgery or organ transplant who need insulin therapy. The monitor measures blood sugar continuously to help doctors manage insulin doses more safely.
PragueAges 18 years+ - NCT07790172Recruiting
Risk factors for incisional hernia after major abdominal surgery
This study looks at why some people develop an incisional hernia (a bulge near a surgery scar) after major abdominal surgery. By joining, you may help researchers identify risk factors to improve future surgical care.
SohagAges 18 years+ - NCT05355909Recruiting
High-intensity pre-surgery training before major belly surgery
This trial tests whether a structured, high-activity fitness program before elective abdominal surgery can help you prepare and recover better. It’s meant for people considered at moderate to high surgical risk who can safely do pre-op exercise.
Innsbruck, TyrolAges 18–99 - NCT03113435Recruiting
Oxygen plan during major belly surgery for adults
This study tests a more guided oxygen plan during long major abdominal operations to help manage how much oxygen your body uses. It compares the new oxygen approach to the current standard method during surgery.
RomaAges 18 years+ - NCT07329530Recruiting
Muscle and metabolism study in ICU survivors
This study looks at muscle and metabolism changes in people who have been in the ICU for at least 7 days after major abdominal surgery. It aims to understand how recovery affects the body.
LiègeAges 18 years+ - NCT06871150Recruiting
Fluid management during major abdominal cancer surgery
This trial compares three different approaches to guiding fluid management during major abdominal cancer surgery. The goal is to find the best way to maintain stable blood pressure and organ function during the procedure.
Bergamo, ItalyAges 65 years+ - NCT06799832Recruiting
Guiding fluid management during major abdominal surgery using a new index
This study tests whether a new tool, the urethral perfusion index, can help doctors better manage fluids during and after major abdominal surgery. It uses standard catheters already in place, so there's no extra device needed.
HamburgAges 45 years+ - NCT06387303RecruitingEarly Phase 1
Comparing IV Methadone vs Spinal Morphine for Pain After Abdominal Surgery
This study compares two strong painkillers—methadone given through an IV versus morphine injected into the spine—to see which provides better pain relief and recovery after major abdominal surgery. It may help you if you're having open surgery and want less pain afterward.
Charlottesville, VirginiaAges 18–75 - NCT06704451Recruiting
IL-33 and memory after major abdominal surgery
This study looks at whether a protein called IL-33 is linked to memory and thinking problems that can happen after major abdominal surgery. It may help doctors find patients at risk earlier.
Kunming, YunnanAges Any age - NCT06753409Recruiting
Brain monitoring during anesthesia for major abdominal surgery
This study tests whether using a special brain wave monitor during anesthesia can improve recovery for people having major abdominal surgery lasting more than two hours.
AsyutAges 18–70 - NCT07651722Recruiting
Pain control and gut recovery after abdominal surgery
This trial tests a combination of two pain-management approaches—a long-acting numbing medicine injected near nerves and a self-administered opioid—to see if they help your gut function better and control pain after bowel or colon surgery.

Best timing for lung expansion moves during surgery
This trial tests different time intervals for a lung-opening technique (alveolar recruitment) during planned abdominal surgery, aiming to restore 90% of lung volume. It may help lower the risk of lung complications after surgery.
