Do I need a tetanus shot when I cut my finger with a kitchen knife?

If the knife cuts the finger, it is not necessary to get tetanus. This is mainly related to the depth of the cut. If it is only epidermal injury, it is not necessary to get tetanus at this time. You can also use iodophor for disinfection treatment. However, if the deep injury or even the tendon is injured, you should go to the hospital in time and need timely debridement and suture. Moreover, it is necessary to inject tetanus vaccine. Because deep injuries may cause anaerobic infection and show tetanus. Tetanus is a serious disease, no specific drugs, poor prognosis, can only alleviate symptoms.
