Giải thích
Children have small, mobile veins and a limited total blood volume, so a 23 gauge winged set with pediatric-volume tubes reduces trauma and blood loss. A large 18 gauge needle is unnecessarily traumatic, prolonged tourniquet time causes hemoconcentration, and lower-extremity draws require provider authorization. Comforting and safely holding the child also improves success on the first attempt.
