In this study, propofol was tested to see if it could help reduce brain injury caused by bacterial toxins in rats. The researchers divided the rats into three groups: one group got the toxin only, one group got the toxin plus propofol, and one was a control group. They found that the rats given propofol had lower brain water content and less inflammation compared to those only given the toxin. The brain injury was also less severe in the propofol group when compared to the toxin-only group. This suggests that propofol can help protect the brain from the harmful effects of bacterial toxins.
