Tetanus Risk from Open Wounds: Prevention, Symptoms, and Urgency

Cause

Clostridium tetani spores in soil, dust, manure enter through breaks in skin (punctures, burns, crush injuries, contaminated wounds).

Clinical Features

• Trismus (lockjaw)
• Risus sardonicus (facial spasm)
• Generalized muscle rigidity, opisthotonus
• Paroxysmal spasms triggered by stimuli
• Autonomic instability (labile BP, tachycardia, fever)
• Dysphagia, respiratory compromise

Prevention

• Primary vaccination: DTaP (children), Tdap (adolescents/adults).
• Booster: Td or Tdap every 10 years.
• Wound management: Clean, debride; assess tetanus immune status; give Tdap/Td + TIG if indicated (see CDC wound table).

Urgency

Tetanus is a medical emergency. If symptoms develop, immediate hospitalization, human tetanus immune globulin (HTIG), IV metronidazole, airway control, spasm control (benzodiazepines, neuromuscular blockade), and autonomic management in ICU are required. Mortality remains 10–20% even with modern care.
