1. Introduction to Tetanus
Tetanus, often known as “lockjaw,” is a severe communicable disease characterized by painful muscle contractions, particularly of the jaw and neck muscles. Despite being preventable through vaccination, tetanus remains a significant health concern, especially in developing countries.
For pediatric nurses, understanding the complexities of tetanus in children is essential, as early identification and proper management can significantly reduce mortality and morbidity. The primary focus of modern healthcare is on prevention through immunization, but nurses must also be prepared to provide comprehensive care when cases occur.
Quick Facts
- Caused by Clostridium tetani bacteria
- Not contagious person-to-person
- Preventable through vaccination
- High fatality rate if untreated
- Global reduction in cases by 95% since 1980s
Prevention Spotlight
Timely administration of tetanus toxoid-containing vaccines is the cornerstone of tetanus prevention in children. The most effective strategy for eliminating tetanus is achieving and maintaining high immunization coverage with DTaP/Tdap vaccines according to recommended schedules.
2. Pathophysiology
Causative Agent and Mechanism
Tetanus is caused by the exotoxin tetanospasmin produced by Clostridium tetani, an anaerobic, gram-positive, spore-forming bacillus. These spores are found ubiquitously in soil, dust, and animal feces. They are extraordinarily resistant to heat, desiccation, and most antiseptics, allowing them to persist in the environment for years.
Infection Process
- Spores enter the body through wounds, particularly deep puncture wounds, burns, or crush injuries that create anaerobic conditions
- In anaerobic environments, spores germinate into vegetative bacteria
- Bacteria produce tetanospasmin toxin
- Toxin enters local nerve endings and travels via retrograde axonal transport
- Reaches the central nervous system in 2-14 days
Neurotoxic Effects
Tetanospasmin is one of the most potent toxins known, with an estimated minimum lethal dose of 2.5 ng/kg body weight. Once in the CNS, the toxin:
BLOCKS: Mechanism of Tetanus Toxin
- Binds to presynaptic inhibitory neurons
- Light chain enters cytosol via heavy chain-created pore
- Obstructs neurotransmitter release (GABA & glycine)
- Cleaves synaptobrevin protein in vesicles
- Kills inhibitory control of motor neurons
- Spasm production due to unopposed excitatory signals
The toxin primarily affects the inhibitory pathways, blocking release of neurotransmitters that normally inhibit motor neuron activity. This disinhibition leads to the characteristic muscle spasms and rigidity of tetanus. Once fixed to neurons, tetanospasmin cannot be neutralized by antitoxin, and recovery requires the development of new nerve terminals.
3. Types of Tetanus
| Type | Description | Features in Children | Prognosis |
|---|---|---|---|
| Generalized Tetanus | Most common form (80-90% of cases) | Descending pattern: jaw, neck, trunk, extremities; painful spasms | Moderate to severe; 10-20% mortality with treatment |
| Localized Tetanus | Limited to muscles near the wound site | Persistent rigidity confined to injury area | Mild; rarely fatal, may progress to generalized form |
| Cephalic Tetanus | Rare form associated with head injuries or ear infections | Cranial nerve palsies, facial muscle involvement | Severe; 15-30% mortality, often progresses to generalized |
| Neonatal Tetanus | Occurs in newborns, usually via umbilical stump | Poor feeding, irritability, rigidity, spasms | Very severe; 70-100% mortality without intensive care |
Critical Note: Neonatal Tetanus
Neonatal tetanus deserves special attention as it remains a significant cause of infant mortality in developing countries. It typically presents within 3-14 days after birth with:
- Inability to suck or breastfeed
- Excessive crying
- Muscle spasms and rigidity
- Opisthotonus (extreme arching of back)
Primary prevention: Maternal vaccination during pregnancy, clean delivery practices, and proper umbilical cord care are crucial preventive measures.

TETANUS: Key Clinical Signs in Children
- Trismus (lockjaw) – early, distinctive sign
- Exaggerated reflexes and muscle hypertonicity
- Temperature elevation, especially in severe cases
- Autonomic dysfunction (sweating, tachycardia, BP fluctuations)
- Neck stiffness and difficulty swallowing
- Upset by stimuli (noise, light, touch can trigger spasms)
- Sardonicus (risus) – characteristic facial expression
5. Diagnosis
Diagnostic Approach
Tetanus diagnosis is primarily clinical, based on characteristic signs and symptoms. Laboratory confirmation is rarely available or necessary. The following elements are crucial for pediatric nurses in the diagnostic process:
Clinical Assessment
- Thorough history of injuries or potential exposure
- Vaccination status evaluation
- Physical examination focusing on muscle tone and reflexes
- Assessment of trismus (lockjaw)
- Evaluation of response to stimuli
- Spatula test (gag reflex triggers spasm instead of gag)
Differential Diagnosis
- Dystonic drug reactions
- Strychnine poisoning
- Meningitis
- Encephalitis
- Hypocalcemic tetany
- Rabies
- Peritonsillar abscess (in trismus)
Diagnostic Criteria
| Component | Finding |
|---|---|
| History |
|
| Physical Examination |
|
| Laboratory Tests |

Prevention Impact on Diagnosis
Effective prevention through immunization has made tetanus increasingly rare in developed countries, which paradoxically can lead to diagnostic delays as clinicians may have limited experience with the disease. Nurses should maintain a high index of suspicion for tetanus in partially immunized or unimmunized children with compatible symptoms, as early recognition is key to improved outcomes.
6. Nursing Management in Hospital
Initial Assessment and Interventions
Tetanus is a medical emergency requiring immediate hospitalization, preferably in an intensive care unit. The nursing management focuses on comprehensive care addressing multiple body systems:
| Priority | Nursing Interventions | Rationale |
|---|---|---|
| Airway Management |
|
Laryngospasm and respiratory muscle spasms are common life-threatening complications |
| Wound Care |
|
Removes source of infection and prevents continued toxin production |
| Pharmacological Support |
|
TIG neutralizes unbound toxin; antibiotics reduce bacterial load; sedation controls spasms and pain |
Nursing Care Plan for Tetanus
1. Nursing Diagnosis: Ineffective Breathing Pattern
Related to: Laryngospasm, respiratory muscle rigidity, and excessive secretions
Evidenced by: Shallow breathing, decreased oxygen saturation, use of accessory muscles
Interventions:
- Position patient to maximize chest expansion
- Monitor respiratory rate, depth, and oxygen saturation continuously
- Provide supplemental oxygen as prescribed
- Perform suctioning as needed, being careful not to trigger spasms
- Assist with ventilatory support as needed
- Prepare equipment for emergency airway management
Expected Outcomes:
- Maintains adequate respiratory function
- Oxygen saturation remains >95%
- Airways remain patent
2. Nursing Diagnosis: Risk for Injury
Related to: Muscle spasms, seizure-like activity, and autonomic instability
Interventions:
- Create a quiet, dimly lit environment
- Minimize unnecessary stimulation (noise, touch)
- Provide padded side rails if appropriate
- Administer muscle relaxants and sedatives as prescribed
- Position to prevent contractures and pressure injuries
- Monitor for signs of autonomic instability
Expected Outcomes:
- No injuries from muscle spasms
- Reduced frequency and severity of spasms
- Stable vital signs
3. Nursing Diagnosis: Imbalanced Nutrition
Related to: Dysphagia, trismus, increased metabolic demands
Evidenced by: Inability to take oral nutrition, weight loss, negative nitrogen balance
Interventions:
- Assess nutritional status daily
- Collaborate with dietitian for appropriate caloric needs
- Administer enteral or parenteral nutrition as prescribed
- Monitor weight, fluid balance, and laboratory values
- Provide oral care regularly
Expected Outcomes:
- Maintains adequate nutritional status
- Shows positive nitrogen balance
- Weight remains stable or improves
Special Considerations in Pediatric Tetanus
- Anxiety management: Children may experience extreme fear during spasms; age-appropriate comfort measures are essential
- Fluid management: Children are more susceptible to dehydration and electrolyte imbalances
- Pain assessment: Use age-appropriate pain scales to ensure adequate pain control
- Family involvement: Incorporate parents/caregivers in care when possible to minimize patient anxiety
- Developmental support: Prolonged hospitalization requires attention to developmental needs
7. Nursing Management at Home
Transition from Hospital to Home
Recovery from tetanus is often prolonged, requiring weeks to months. Home care planning begins while the child is still hospitalized. The transition requires comprehensive education and support for families to ensure continued recovery and prevention of complications.
Discharge Planning
- Assess home environment for safety and accessibility
- Identify necessary home modifications or equipment
- Arrange for home healthcare services if needed
- Ensure follow-up appointments are scheduled
- Verify complete immunization plans
- Develop emergency response plan
Home Assessment

Preventing Recurrence
Having tetanus does not confer natural immunity. Ensure the child completes the full immunization series for future prevention. Nurses should verify that:
- Age-appropriate vaccination is initiated or continued once the child’s condition stabilizes
- All family members are up-to-date with tetanus immunization
- Caregivers understand the importance of future booster doses
- Proper wound care practices are understood for prevention of future infections
8. Prevention Strategies
Immunization as Primary Prevention
Vaccination is the cornerstone of tetanus prevention. Since the introduction of tetanus toxoid in routine immunization programs, there has been a dramatic reduction in tetanus cases worldwide. For nurses, understanding and advocating for proper immunization is a critical responsibility.
| Age | Vaccine | Notes |
|---|---|---|
| 2 months | DTaP (1st dose) | Combined with diphtheria and pertussis protection |
| 4 months | DTaP (2nd dose) | Series continuation |
| 6 months | DTaP (3rd dose) | Series continuation |
| 15-18 months | DTaP (4th dose) | Booster |
| 4-6 years | DTaP (5th dose) | Booster before school entry |
| 11-12 years | Tdap | Adolescent booster |
| Pregnancy | Tdap | During each pregnancy (preferably 27-36 weeks) |
| Every 10 years | Td or Tdap | Lifetime boosters |
PROTECT: Tetanus Prevention Strategy
- Prompt immunization according to schedule
- Regular boosters every 10 years
- Optimal wound care for all injuries
- Thorough cleaning of wounds
- Education about tetanus risks
- Community vaccination programs
- Timely tetanus prophylaxis after injuries
Wound Management for Prevention
Proper wound care is a critical secondary prevention strategy, especially for children with uncertain vaccination status or those with tetanus-prone wounds.
Tetanus-Prone Wounds
- Puncture wounds
- Wounds with devitalized tissue
- Wounds contaminated with soil or manure
- Burns
- Crush injuries
- Frostbite
- Wounds with foreign bodies
- Wounds older than 6 hours
Proper Wound Care Steps
- Wash hands thoroughly
- Clean wound with soap and water
- Remove debris and foreign bodies
- Allow wound to bleed briefly to flush out bacteria
- Apply antiseptic
- Cover with clean dressing
- Seek medical attention for tetanus-prone wounds
Post-Exposure Prophylaxis
| History of Tetanus Immunization | Clean, Minor Wounds | Tetanus-Prone Wounds |
|---|---|---|
| Unknown or <3 doses | Td/Tdap | Td/Tdap AND Tetanus Immune Globulin (TIG) |
| ≥3 doses, last dose <5 years ago | No prophylaxis needed | No prophylaxis needed |
| ≥3 doses, last dose 5-10 years ago | No prophylaxis needed | Td/Tdap |
| ≥3 doses, last dose >10 years ago | Td/Tdap | Td/Tdap |
Neonatal Tetanus Prevention
Neonatal tetanus prevention requires a multi-faceted approach:
- Maternal immunization during pregnancy (preferably at least 2 doses)
- Clean delivery practices with sterile instruments
- Proper umbilical cord care with antiseptics
- Education about avoiding traditional harmful practices (e.g., application of substances to the umbilical stump)
- Expanding access to skilled birth attendants
These preventive measures have led to elimination of neonatal tetanus in many countries.
