Is there first aid treatment and care of toe laceration?

Soap & water. Wash all cuts as soon as possible with soap and water, or at least flush with water if unable to wash, and remove any visible foreign bodies. Then cover with polysporin (bacitracin and polymyxin) (not neosporin!) & a bandage, bringing the wound as closely together as possible, and apply pressure if bleeding continues. If large/deep, over a joint, still bleeding, or difficulties beyond the wound, seek medical care.
Keep clean and dry. An otherwise uncomplicated toe laceration should be cleaned initially to remove dirt. If superficial, keep it covered, clean, & dry. It may heal faster if protected in a loose fitting shoe with a firm sole. If it is deep, seek evaluation to see if it needs sutured. If it is very deep or there is concern that other structures are injured, eg tendons or nerves, seek evaluation.
