Article Synopsis
- Intraoperative hypotension is when patients' blood pressure drops during surgery, which can lead to serious health problems.
- Researchers wanted to understand why this happens in patients undergoing major abdominal surgery by using a method called machine learning.
- They discovered six different types of low blood pressure during surgery, which could help doctors give better treatments to patients experiencing these issues.
Background: Cardiac output is an important hemodynamic variable and determines oxygen delivery. In contrast to blood pressure, cardiac output is rarely measured even in high-risk surgical patients, suggesting that clinicians consider blood pressure to be a reasonable indicator of systemic blood flow. However, the relationship depends on constant vascular tone and volume, both of which routinely vary during anesthesia and surgery.
