This study looks at whether a quick, painless neck ultrasound before surgery can help predict which older patients (65+) will experience a dangerous drop in blood pressure during spinal anesthesia. Researchers will measure the size and flexibility of a neck vein in 85 participant…

This study watches 254 adults after elective surgery to see what factors affect how much pain medicine they need in the recovery room. No new treatments are given—just routine care. The goal is to find patterns that help doctors personalize pain management and improve recovery.

This study looks at whether measuring skin conductance (a sign of nerve activity) can help predict sudden drops in blood pressure after spinal anesthesia in older adults with cancer. About 100 patients aged 65 and older having urologic cancer surgery will be monitored. The goal i…

This study observes 500 adults aged 65 and older having major abdominal surgery to see if those who receive an ultrasound-guided nerve block for pain have fewer lung complications within 7 days after surgery. The choice of pain management is made by the care team, not the study. …

This study looks at different scoring systems to see which best predicts whether a person will need intensive care after cancer surgery. Researchers will follow 500 adults having cancer surgery and compare the accuracy of these tools. The goal is to help doctors plan better and u…

This study looks at two ways of helping patients breathe during lung surgery when only one lung is used. One method is newer and controls airflow more precisely, while the other is standard. Researchers will measure oxygen levels and lung function in 60 adults to see if the newer…

This study looks at small molecules in the blood (called metabolites) to find differences between people with severe traumatic brain injury and those with other injuries like broken bones. Researchers will take blood samples from 60 adults and analyze them to see if certain patte…

This study watches 134 adults having chest surgery to see if the time one lung is used for breathing affects lung problems like pneumonia or ARDS. It does not test a new treatment but aims to find a safer surgery window. Results may help doctors plan better to reduce risks.

This study looks at whether the quality of sleep before breast cancer surgery affects pain and inflammation after the operation. Researchers will track 150 women, measuring their sleep quality, blood markers of inflammation, and pain levels. The goal is to see if poor sleepers ha…
