A medical technique using electrical current to stop bleeding by coagulating blood vessels.
From electro- + hemostasis (Greek haima, blood + stasis, stopping). This surgical technique emerged in the late 19th century when surgeons discovered electricity could cauterize wounds.
Surgeons can stop bleeding during surgery using a tool called an electrocautery that zaps blood vessels, fusing them shut in milliseconds—it's basically controlled burning to save lives!
