WOUND TOILET, TETANUS ASSESSMENT & SAFETY-NETTING (NO DRUG THERAPY)
Same for children; the tetanus decision uses the same wound classification.
Post-Exposure Tetanus Prophylaxis - disease-level clinical article (tetanus-prophylaxis-clinical.txt)
The non-drug backbone. Cleaning and debridement carry the tetanus source's own instruction that prophylaxis is given in conjunction with them, not instead of them.
- Classify the wound before deciding tetanus cover. The source's split is low risk (clean and minor) versus high risk (contaminated, puncture, avulsions, or resulting from missiles, crushing, burns, animal or human bites, or frostbite).
- Fewer than 3 prior doses or unknown: give the vaccine for a low-risk wound; for a high-risk wound give both the vaccine and human tetanus immune globulin.
- Three or more prior doses: vaccine only if the last dose was over 10 years ago for a low-risk wound, or over 5 years ago for a high-risk wound.
- Give prophylaxis as soon as possible, and still give it on delayed presentation - the incubation period is long and variable.
- Look for a retained foreign body and for compromised blood supply. A missed foreign body is listed as a predisposing factor for tetanus.
- Tetanus-prone wounds may be left open, to avoid the anaerobic conditions the organism needs.
