Controlling blood pressure during esophagus surgery

This study compares two ways to manage pain after minimally invasive esophagectomy: a paravertebral catheter (a small tube near the spine) versus epidural analgesia (a tube in the back). The goal is to see which method provides better pain relief with fewer side effects.

This trial tests a combination of a medication called esketamine and raising both legs to keep blood pressure stable when older adults go under anesthesia for chest surgery. It may help avoid sudden drops in blood pressure during the start of anesthesia.

This trial tests whether giving small doses of ephedrine during surgery can prevent dangerously low blood pressure in adults undergoing major abdominal surgery. It may help patients who are at risk for this complication.

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.

This trial tests a pain-control method (using an epidural/nerve pain-block through the back, called neuraxial anesthesia) for people having minimally invasive esophagus removal surgery. It may help reduce pain after surgery and improve comfort during recovery.

This study looks at how epidural anesthesia (numbing medicine injected near your spine) affects your heart's pumping function during surgery. Researchers will use a special heart ultrasound to check this, which may help make surgery safer in the future.
