This study looks at whether measuring skin conductance, a sign of nerve activity, can predict sudden drops in blood pressure after spinal anesthesia in older cancer patients. About 100 people aged 65 and older having urologic cancer surgery will be monitored. The goal is to find …

This study looks at 500 adults having cancer surgery to see which risk score best predicts if they'll need intensive care afterward. Doctors will compare several scoring tools to find the most accurate one. The goal is to help plan better care and use hospital resources wisely.

This study is observing 150 women scheduled for breast cancer surgery to see if their sleep quality before the operation can predict how much pain and inflammation they will have afterward. Participants will fill out a sleep questionnaire, and researchers will track their pain le…

This study looks at two ways to help patients breathe during lung surgery when only one lung is used. It compares a newer method called flow-controlled ventilation with a standard method. The goal is to see which one improves oxygen levels and lung function. About 60 adults havin…

This study looks at whether using ultrasound-guided nerve blocks for pain relief after major abdominal surgery can lower the chance of lung complications. Researchers will observe 500 adults aged 65 and older who are having elective surgery. The study does not assign treatments; …

This study watches 254 adults after elective surgery to see what factors affect how much pain medicine they need in the recovery room. Researchers will collect data from normal care—no extra treatments or changes. The goal is to find patterns that help doctors personalize pain ma…

This study observes 134 adults having chest surgery to see if the time one lung is deflated (single-lung ventilation) is linked to lung complications like pneumonia or breathing trouble. Researchers will track ventilation time and check for problems within a week after surgery. T…

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 looks at chemical markers in the blood of people with severe traumatic brain injury (TBI) compared to those with broken bones but no brain injury. Researchers aim to find differences that could help doctors better understand injury severity and predict recovery. The st…
