Restraints are protective devices used to limit patient movement during medical procedures. They are used to immobilize body parts, restrict activity for safety and security, and prevent removal of life-supporting equipment or self-harm. Common types include clove hitch restraints for limbs, mitten restraints for hands, elbow restraints, mummy restraints for small children, jacket restraints, and safety belts. Proper application and nursing care of restraints is important to prevent tissue damage, pressure sores, and other hazards.
