Postoperative clinical trials

Comparing two pain medicines after C-section

This trial compares two pain relievers, hydromorphone and nalbuphine, given through a patient-controlled pump after cesarean section. It aims to find which provides better pain control with fewer side effects.

Minimal surgery with gel for macular hole

This study tests a new, less-invasive surgery for macular holes. The surgeon uses a tiny gel to help close the hole without removing as much gel-like fluid from your eye as usual. It may help your vision recover with less risk.

Brain waves during surgery in older adults

This study looks at brain wave patterns during surgery in older adults to better understand and predict confusion after surgery. If you are 60 or older and having joint or spine surgery, you may be able to help.

Surgery to stop windpipe collapse in babies with esophageal atresia

This trial tests a surgery called posterior tracheopexy to prevent the windpipe from collapsing in babies with esophageal atresia and tracheomalacia. It may help your child breathe more easily.

Shoulder replacement and pain medication study

This study looks at how your pain tolerance before a total shoulder replacement might relate to how much pain medication you need after surgery. The goal is to help doctors better manage pain medication after surgery.

Tested nerve-block pain pumps after arm or leg surgery

This trial studies whether a timed, stop-and-go pain medicine delivery works better than a steady drip after surgery. It’s done using a small catheter placed near a nerve to help control pain.

Respiratory Variability and Postoperative Complications During Thoracic Lung Resection.

Efficacy of Tramadol With Ropivacaine for Modified Pectoral Nerve Block in Breast Cancer Surgery

Managing Pain After Knee Replacement Surgery

This study looks at how "rebound pain" (increased pain when pain medication wears off) affects long-term pain after total knee replacement. Researchers want to understand this connection and potentially improve pain management strategies for knee surgery patients.

Electrical stimulation for pain after thyroid surgery

This trial tests if electrical stimulation can help reduce pain after thyroid surgery. It is for people who have at least moderate pain after their operation.

How fasting time before banding affects bleeding risk

This study looks at whether the length of time you fast before a procedure to treat varices (enlarged veins in the esophagus) affects the chance of bleeding after the procedure. The procedure, called banding, places small rubber bands around the veins to stop or prevent bleeding.

Pain relief after hip replacement surgery

This study compares two types of nerve blocks for pain relief after hip replacement surgery. It aims to find which method reduces pain and improves recovery.

Using a pain monitor to time breathing-tube removal

This study tests whether a special monitor can help doctors know when it's safe to take a breathing tube out after surgery in the ICU. The monitor looks at pain signals, and the goal is to make the process of breathing on your own again more comfortable.

Melatonin to prevent waking confusion in young children after surgery

This study tests whether giving melatonin before surgery can help prevent agitation and confusion in young children after they wake up from anesthesia. Participation may help your child have a smoother recovery after their procedure.

CT scan to predict liver failure after surgery

This trial uses special CT scans to create a map of your liver's blood vessels before surgery. The goal is to predict if your liver might fail after part of it is removed, so doctors can better plan your care.

Video education for gallbladder surgery recovery

This trial tests whether watching an educational video before gallbladder removal surgery can improve trust in your doctor, reduce pain, and lower anxiety. It may help you feel more prepared and calm before and after your procedure.

Mouth rinse and cold therapy for lower molar pain

This study tests whether using different strengths of a disinfectant rinse inside the tooth, sometimes combined with cold therapy, can reduce pain after a type of root canal treatment for lower molars. It aims to find the most comfortable and effective approach for managing post-procedure pain.

Long-acting vs standard numbing for nose surgery pain

This study compares two types of numbing medicine used during open rhinoplasty (nose surgery) to see which one controls pain better after surgery. One is a long-acting version (liposomal bupivacaine) and the other is the standard numbing medicine (bupivacaine).

Comparing sedatives for nausea after gallbladder surgery

This study compares two different sedative medications used during anesthesia to see which one helps prevent nausea and vomiting after gallbladder removal surgery. Participating may help you recover more comfortably after your procedure.

Mobilization and caffeine after cesarean

This trial tests whether getting out of bed and drinking coffee after a planned cesarean can help reduce pain and speed up recovery. It is for women who have moderate to severe pain after surgery.

Breathing exercises for pain after cesarean

This study tests if a gentle breathing technique called Pranayama can help reduce pain after a planned cesarean. It compares the breathing exercise to usual care to see if it improves recovery.

Using hernia sac flap to cover mesh in bony-edged hernia repair

This trial tests whether using a flap of your own hernia sac to cover the mesh during hernia repair can improve healing. It's for people with a complex hernia that touches a bone, like near the breastbone or pelvis.

Pain block comparison for recovery after liver surgery

This study compares two types of pain-relieving nerve blocks used during liver surgery to see which one helps you breathe better and recover more comfortably after the operation.

Lung surgery planning without a tube, using X-ray guidance

This trial looks at a new way to plan a minimally invasive lung segment removal (“segmentectomy”) using live X-ray guidance, without using a chest tube (“tubeless”). It may help patients with certain small lung lesions (sometimes early lung cancer) get the surgery more precisely.
