What is done for a laceration?

That depends : Depending on the size, area of the body, the laceration may be sutures, taped or even left alone. Let the experts make that decision.

Stitch, tape or glue: Depending on the depth of the injury, deeper structures may also need to be repaired (tendons, nerves, ducts), and if these are missed by just closing the skin, you have major issues later. This is why you need an expert (not just steri-strips at home) to evaluate the injury. Some er docs even miss things they shouldn't, so if it's deep, see an expert in the area of injury (plastic surgeon, etc.).
