Risky reduction in blood pressure during surgery can be predicted Interior

The study results will be published on Monday in the scientific journal JAMA. Whether these complications can really be prevented in this way would, according to the researchers, be ‘logical’, but still needs to be definitively scientifically proven.

In 2018, 320 million people underwent surgery worldwide and one in five had a complication. Anesthesiologists are already looking at a possible fall in blood pressure during a procedure. “The problem is that the operating team only responds when the blood pressure falls below a certain limit,” says researcher Denise Veelo. “On average you are a few minutes late with your intervention,” says fellow researcher Bart Geerts.

The American medical technology company Edwards Lifesciences developed a system that gives a warning before the blood pressure goes down, depending on the cause two to fifteen minutes in advance. It has now been investigated whether it works for approximately one hundred OR patients. The hypotension was indeed found to be shorter. “In the group receiving standard care, the researchers saw about 33 minutes of low blood pressure per patient. For the group in which the warning system was used, it was around 8 minutes. “
