Introduction
A sewing needle puncture penetrating 1 cm deep generally does not lead to tetanus if properly managed promptly. However, the risk of infection increases if the needle is rusty, the wound is contaminated, or the person has not received a tetanus vaccine. In such cases, medical attention should be sought promptly and treatment should follow medical advice. If the sewing needle is clean and free of rust, the wound is superficial, thoroughly cleaned immediately, and the individual has received a tetanus vaccine within the past 5–10 years, the risk is low.
A sewing needle puncture of 1 cm in depth generally does not lead to tetanus if properly treated promptly. However, the risk of infection increases if the needle is rusty, the wound is contaminated, or the person has never received a tetanus vaccine. In such cases, prompt medical attention is necessary, and treatment should be administered according to medical advice.
If the sewing needle is clean and rust-free, the wound is superficial, thoroughly cleaned immediately, and the individual has received a tetanus vaccine within the past 5–10 years, the risk of infection is low. The wound can be managed by disinfecting with iodine tincture, keeping it dry, and closely monitoring for any changes.
However, if the needle is rusty, there is debris left in the wound, or the person has never been vaccinated against tetanus or has an unclear vaccination history, even a 1 cm deep wound may allow Clostridium tetani bacteria to grow and cause infection. In such cases, medical care is required for proper wound debridement, and tetanus antitoxin or a tetanus vaccine may need to be administered depending on the situation.
For daily care, keep the wound clean and dry, avoid contact with water and pressure, change dressings as directed by a healthcare provider, and monitor for signs of redness, increased pain, or abnormal discharge. Seek follow-up medical care promptly if any discomfort occurs, and ensure adequate rest to strengthen the body's immunity.
