This depends on the condition of the wound. If the wound is deep and small, and there is insufficient oxygen, then treatment for tetanus is necessary. In cases of open fractures or blast injuries with heavy contamination, such as contamination with soil or rust, treatment for tetanus is mandatory. This is because tetanus is caused by the invasion of Clostridium tetani into human mucous membranes, producing a toxin that causes muscle spasms in the body, particularly affecting the jaw and respiratory muscles, leading to oxygen deprivation and asphyxiation. Therefore, if the wound requires treatment with a tetanus shot, treatment for tetanus is essential.
