Could the type of anesthesia prevent a deadly complication in hip surgery?

This study looks at whether the type of anesthesia (general vs. neuraxial, like a spinal block) affects the risk of bone cement implantation syndrome (BCIS) in adults having hip fracture surgery. BCIS can cause dangerous drops in blood pressure, breathing problems, and even cardiac arrest. The goal is to see if neuraxial anesthesia leads to fewer cases of BCIS and lower levels of certain immune markers. The results could help doctors choose safer anesthesia for these patients.
