My daughter had mountain biking acc and something punctured her thigh. ER kept us in waiting room for over 3 hr and then in room for another 3 hrs before actual treatment. Wound kept bleeding through covering. They would not stitch as a puncture wound. Large hematoma under wound. They flushed wound and put antibiotic salve and non stick bandage and a tonight gauze padding and a ace bandage to keep tight due to hematoma. This cleansing and wrapping took place finally about 4:30 yesterday morning, nearly 6 hrs after in ER. When can she remove non stick bandage and clean wound again? We removed the ace bandage and the layers of gauze used for padding are soaked in blood.
