ANESTHESIA

This pilot study tested a device called the Learning Intravenous Resuscitator (LIR) that automatically gives IV fluids during major abdominal surgery under general anesthesia. The goal was to see if the device could keep blood volume stable as well as a human anesthesiologist. On…

This study tested a device that delivers high-flow oxygen through the nose during throat surgery. The goal was to keep patients' oxygen levels safe without using a breathing tube. The trial included 29 adults in two French hospitals. The device was considered safe if blood oxygen…

This study tested a new sensor measure called RPVi to see if it can predict how patients will respond to fluids during surgery. Researchers compared RPVi to standard methods in 63 adults having elective surgery. The study was terminated early, so the findings are limited.

This study looked at how anesthesia changes brain activity in people with Parkinson's disease or essential tremor who were already scheduled for deep brain stimulation (DBS) surgery. Researchers recorded brain signals during a short period of anesthesia to understand which circui…

This study looked at 50,000 adults who had non-cardiac surgery under general anesthesia. Researchers wanted to see if the type of anesthesia used was linked to serious heart or brain problems after surgery. The goal was to find safer ways to give anesthesia.
