DSA vs. BIS for Anesthesia and Analgesia Management

The purpose of this study is to compare two different methods of monitoring brain activity (anesthesia depth) during gynecological surgeries. When patients undergo surgery under general anesthesia, doctors use monitors to ensure they are at the right level of sleep and pain relief. Traditionally, a method called the Bispectral Index (BIS) is used, which provides a single number to represent brain activity. A newer method, called Density Spectral Array (DSA), provides a more detailed, color-coded map of brain waves in real-time. Researchers want to see if using the more detailed DSA map helps anesthesiologists adjust medication more precisely. The study will compare the total amount of anesthetic and pain-relief drugs used in patients monitored with DSA versus those monitored with BIS. The goal is to determine if DSA leads to more personalized care, potentially reducing drug use and improving recovery after surgery
