Answer

Immunizations

Snakes do not harbor Clostridium tetani in their mouths, and the risk of acquiring tetanus following snake envenomation is exceptionally low. That said, if a patient's tetanus immunization is not current, a TDaP should be administered while the patient is being evaluated. However, tetanus immunoglobulin in unnecessary.

Diphtheria-tetanus toxoid (Decavac)

Diphtheria-tetanus toxoid is used to induce active immunity against tetanus in selected patients. The immunizing agents of choice for most adults and children older than 7 years are tetanus and diphtheria toxoids. It is necessary to administer booster doses to maintain tetanus immunity throughout life.

Pregnant patients should receive only tetanus toxoid, not a product containing the diphtheria antigen.

In children and adults, one may administer into the deltoid or midlateral thigh muscles. In infants, the preferred site of administration is the mid thigh laterally.
