I have an open wound semi deep on my big toe caused by glass. What is the best way to care for an open wound (skin taken off).

Laceration. You are way late in asking this question! if you have a laceration of your toes so that the skin is laid open, you should have had this looked at, explored, cleansed, and bandaged or sutured at that time. If your doctor says it is too late (a matter of hours) to be sutured, then you should be treating it as she or he suggests.
Clean and protect. Be sure the wound is as clean as possible dress it with nonstick sterile dressing. If it is large, still bleeding or seems to have glass in it still see your doctor. If this was a dirty piece of glass outside check your tetanus vaccine statusif freshly broken glass inside you should be fine.
Toe wound. Ensure all glass pieces are out of the wound. If so, wash thoroughly daily. Then, place antibiotic ointment on the wound and cover with clean band aid or sterile bandage, and cover with tape iif neceasary for bandage adherence. If ever the wound has redness, warmth and swelling, drainage or a bad odor, please get it evaluated. Dont wait, if you have diabetes; get it evaluated asap.
Advice. After trying to pick out any foreign object leave skin flap intact.
Keep it clean!!! If you are not planning on seeing a doctor, keep the would clean, keep the edges as closed as possible and keep pressure off the area. It should heal without stitches, provided you know how to treat such a cut. If not, you better see a doctor for evaluation and more advice.
Local hygiene. Wash with soap and water. Apply antibiotic ointment and cover with a dressing. Don't leave it open to air. Check your tetanus status. Is all the glass removed?
Superfast Healing. The real question is what not to do that slows down healing. Avoid using alcohol, peroxide, hibiclens, betadine, and bleach solutions. Inflammation ( red, hot, swollen, tender) is important to healing so anti-inflammatories (motrin, advil) are bad. Cover the area with a clean dressing changed every other day and protected from trauma. Antibiotics do not help healing unless it is truly infected.
