SPINAL ANESTHESIA

This study tests whether adding two pain medicines (dexmedetomidine and fentanyl) to standard spinal anesthesia provides better pain relief after above-knee amputation for lower limb sarcoma. About 58 adults aged 18-60 will be randomly assigned to receive either the drug combinat…

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 whether patients who are more anxious before surgery are more likely to have a sudden drop in heart rate or blood pressure (vasovagal event) during spinal anesthesia. Researchers will measure anxiety levels in 1500 adults and watch for these events. No treatme…

This study looks at whether machine learning (a type of artificial intelligence) can accurately predict how long spinal anesthesia lasts in people having knee replacement surgery. Researchers will use patient information like age, surgery details, and anesthesia data to train com…

This study checks if a woman's waist size, body mass index (BMI), and a heart-related index can predict a common complication of spinal anesthesia during C-sections: a sudden drop in blood pressure. Researchers will measure 321 pregnant women before their scheduled C-section and …

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 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 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…
