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 two easy-to-calculate scores (Shock Index and Modified Shock Index) can predict which women will have dangerously low blood pressure after receiving spinal anesthesia for a planned C-section. Researchers will monitor 300 pregnant women and track how of…

This study tests whether computer programs can accurately predict when spinal anesthesia will wear off after total knee replacement surgery. Researchers will collect data from 140 adults having knee surgery and use machine learning to estimate anesthesia duration. The goal is to …

This study looks at whether measuring skin conductance, a sign of nerve activity, can predict dangerous 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 he…

This study looks at whether feeling anxious before surgery increases the chance of a vasovagal event (like a sudden drop in heart rate or blood pressure) during spinal anesthesia. Researchers will measure anxiety levels in 1500 adults before their operation and watch for fainting…

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…
