Summary
This study tested whether raising a patient's legs before general anesthesia can prevent a sudden drop in blood pressure. Researchers studied 200 adults undergoing surgery. The goal was to see if this simple technique reduces the need for emergency medications and keeps the heart pumping steadily.
