SPINAL ANESTHESIA

This study compares two pain relief methods during spinal anesthesia for above-knee amputation in people with sarcoma of the lower leg. One group gets a standard drug (fentanyl) plus an extra drug (dexmedetomidine), while the other gets fentanyl alone. The goal is to see if the c…

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 looks at whether measuring the size of a vein in the leg with ultrasound before surgery can help predict if an older person's blood pressure will drop too low during spinal anesthesia. About 43 patients over 60 having lower-limb orthopedic surgery will be checked. The …

This study watches 100 pregnant women having planned C-sections to see if the time it takes to deliver the baby changes the baby's cord blood pH and base excess. It compares women who get general anesthesia versus spinal anesthesia. The goal is to learn how delivery timing might …

This study is observing 321 pregnant women having planned C-sections to see if waist size, body mass index (BMI), and a heart rate-to-blood pressure ratio can predict a sudden drop in blood pressure after spinal anesthesia. The goal is to find better ways to identify women at ris…

This study tests two different body landmarks—the top of the hip bone and a point on the lower back—to see which helps doctors find the right spot for spinal anesthesia more accurately in 660 pregnant women having C-sections. The goal is to reduce errors and improve safety by usi…

This study looks at whether two simple calculations using heart rate and blood pressure, taken before surgery, can predict which women will experience a dangerous drop in blood pressure after receiving spinal anesthesia for a planned C-section. Researchers will monitor 300 pregna…

This study looks at whether patients who are more anxious before surgery are more likely to have a sudden drop in heart rate or blood pressure (called a vasovagal event) while receiving spinal anesthesia. Researchers will measure anxiety levels in 1,500 adults and watch for these…

This study tests whether machine learning can accurately predict when spinal anesthesia ends after total knee replacement. Researchers will use patient data like age and surgery details to train computer models. The goal is to help doctors plan better care and improve patient rec…
