What should I do if my finger is cut by a knife? It hurts

Tetanus bacilli is an anaerobic bacterium, which means that it grows well in a closed and anoxic environment. Scratches from iron (especially rusty) or glass are the most dangerous, and the deeper the wound, the more suitable it is for growth, and the wound is better for growth when bandaged and closed. If it is an iron or glass scratch, it is recommended to hit it immediately.

However, it is not only tetanus that can take advantage of the situation, pathogenic bacteria such as Staphylococcus aureus can also cause serious consequences, so it should be disinfected immediately at the time of injury (don't be afraid of pain, preferably iodine tincture) and pay attention to changes in the body (such as body temperature) just in case. There is also a reminder to the landlord that if you unfortunately hurt your finger and bleed a lot in the future, you should press both sides of your finger to stop the bleeding, because the blood vessels of the fingers are running on the side of the fingers, and it is useless to press up and down to break the bones. The incubation period of tetanus is generally 6 to 10 days, and there are also a few months, so you can't let your guard down.

If you have had a tetanus toxoid (i.e. vaccine) (three shots), the validity period can last for 10 years, which means that the tetanus toxin antibody will maintain the effective blood concentration for 10 years after the vaccine. It doesn't matter if you've been injected within 10 years.

1. The wound is relatively shallow

The wound is small, the bleeding is not much, the wound is relatively clean, and the fingers can be bent freely. In this case, you can use medical iodine to disinfect, use a cotton ball dipped in medical iodine to scrub the wound, wait until the wound is dry, and then bandage the wound.

Don't: Do not use water at the wound.

2. The wound is deep

If the knife cuts a deep wound and there is a lot of bleeding from the wound, first stop the bleeding with compression, and then go to the hospital for professional treatment.

3. The finger is cut off

If you are not careful, it will lead to the cutting off of your fingers and twisting. If this happens, you can do it as follows:

Step 1: stop the bleeding, the finger is cut off, the broken place will be bleeding non-stop, at this time you have to raise the finger, lift it up, it is best to call someone for help, and then bandage the wound. If this does not stop the bleeding, a tourniquet is wrapped around the base of the finger (which can be replaced by a regular cleaning cord) to stop the bleeding.

Step 2: Wrap the severed finger in sterile gauze, do not rinse it with water, unless the severed finger is seriously contaminated, and then put it in a clean plastic bag.

How to deal with a hand cut by a knife:

1. Hemostasis is the premise.

Depending on the degree of bleeding from the wound, it is divided into the following two categories. If it is just ordinary bleeding, just find a clean handkerchief or towel to bandage the bleeding site, if there are no relevant items around, use other hands or others to help pressurize the wound, which is not only effective and fast, but also will not leave sequelae.

If there is heavy bleeding, especially in the injury of the arteries, it is necessary to control the blood flow first, you can use a tourniquet or an elastic hose, but it should be remembered that before arriving at the hospital and carrying out regular **, the tourniquet should be loosened every hour, and the time should be controlled at about seven minutes, which is to avoid necrosis of the hand due to too much ischemia.

However, there is one thing to pay special attention to, do not use nylon rope or wire to control the relevant parts of the hand, otherwise the result can only be counterproductive, aggravate the injury, and cause irreparable consequences.

2. It is particularly important to prevent infection.

Don't take it upon yourself to apply some medications without going through the doctor's first opinion, especially those with color, which are likely to hinder the doctor's judgment.

3. Avoid further aggravation of the injury.

If you find that you or someone around you has a broken finger, you can first find some small wooden boards as temporary fixations, so that you can do a good preventive role before the doctor, avoid further aggravation of the injury, and also have a good pain-relieving effect.
