Emergency Department Care
Treatment of tetanus is directed toward the treatment of muscle spasm, prevention of respiratory and metabolic complications, neutralization of circulating toxin to prevent the continued spread, and elimination of the source.
Admit patients to the intensive care unit (ICU). Because of the risk of reflex spasms, maintain a dark and quiet environment for the patient. Avoid unnecessary procedures and manipulations.
Seriously consider prophylactic intubation in all patients with moderate-to-severe clinical manifestations. Intubation and ventilation are required in 67% of patients.
- Attempting endotracheal intubation may induce severe reflex laryngospasm; prepare for emergency surgical airway control. Rapid sequence intubation techniques (eg, with succinylcholine) are recommended to avoid this complication.
- Perform tracheostomy in patients requiring intubation for more than 10 days. Tracheostomy has also been recommended after onset of the first generalized seizure.
Tetanus immune globulin (TIG) is recommended for treatment of tetanus. TIG can only help remove unbound tetanus toxin, but it cannot affect toxin bound to nerve endings. A single intramuscular dose of 3000-5000 units is generally recommended for children and adults, with part of the dose infiltrated around the wound if it can be identified. The World Health Organization recommends TIG 500 units by intramuscular injection or intravenously (depending on the available preparation) as soon as possible; in addition, administer age-appropriate TT-containing vaccine (Td, Tdap, DT, DPT, DTaP, or TT depending on age or allergies), 0.5 cc by intramuscular injection at separate site.
Tetanus disease does not induce immunity; patients without a history of primary TT vaccination should receive a second dose 1–2 months after the first dose and a third dose 6-12 months later.
Surgical therapy includes debridement of wounds to remove organisms and to create an aerobic environment.
- The current recommendation is to excise at least 2 cm of normal viable-appearing tissue around the wound margins.
- Incise and drain abscesses.
- Delay any wound manipulation until several hours after administration of antitoxin due to risk of releasing tetanospasmin into the bloodstream.
Consultations
- An intensive care medicine specialist should be the primary physician coordinating the patient's care.
- Consult a pulmonary medicine specialist after admission to the ICU for patients with severe respiratory symptoms or those requiring mechanical ventilation.
- Consult an anesthesiologist after admission to the ICU if intrathecal baclofen is to be administered.
