In a way that does not involve bloodshed or violence.
The operation was performed bloodlessly, ensuring a quick recovery for the patient.
Bloodlessly → It is formed from "blood" (from Old English "blōd", meaning the red fluid that circulates in the bodies of humans and animals) and "-less" (meaning without). The word "bloodlessly" means without blood or without the shedding of blood.
Think of 'blood' as the vital fluid and '-less' meaning without — so bloodlessly means without blood.
