What is Tetanus Neonatorum?

Tetanus neonatorum, also known as neonatal tetanus, is a severe clinical presentation of generalized tetanus in newborns. It occurs when the baby is infected with Clostridium tetani bacteria, which can be present in unsanitary conditions or practices during birth.

Symptoms and Characteristics

• Symptoms usually appear from 4 to 14 days after birth, averaging about 7 days [1].
• The fatality rate for infants has been estimated as 70% to 100%; death usually occurs by the age of 2 weeks [1].
• Four different forms of tetanus have been described based on clinical findings [4].

Causes and Risk Factors

• Infections can occur when traditional birth practices or unsanitary conditions are present.
• Newborns are at a high risk of developing neonatal tetanus if the baby is born with the help of unhygienic practices.

Definition and Diagnosis

• Tetanus neonatorum is defined as a syndrome of generalized rigidity with muscle spasms and seizures in the neonatal period resulting from Clostridium tetani toxin production [9].
• The WHO definition of non-neonatal tetanus requires at least one of the following signs: sustained spasm of the facial muscles or painful muscular contractions.

Prevention and Elimination

• Neonatal tetanus elimination is considered a proxy for maternal tetanus elimination.
• The estimated annual global NT mortality rate was approximately 6.7 NT deaths per 1000 live births in the late 1980s [14].
• In 1989, the 42nd World Health Assembly called for the elimination of neonatal tetanus by 1995.

Common Signs and Symptoms of Tetanus Neonatorum

Tetanus neonatorum, also known as neonatal tetanus, is a form of generalized tetanus that occurs in newborns who lack the passive protection derived from maternal antibodies. The following are common signs and symptoms of tetanus neonatorum:

• Muscle spasms: One of the most distinctive features of tetanus neonatorum is muscle spasms, which can be severe and painful.
• Irritability and excessive crying: Newborns with tetanus neonatorum often become irritable and cry excessively due to the pain caused by muscle spasms.
• Poor feeding or suckling ability: Infants with tetanus neonatorum may have difficulty feeding or sucking, which can lead to dehydration and other complications.
• Rigidity of muscles: Muscle rigidity is another common symptom of tetanus neonatorum, which can cause the infant's body to become stiff and rigid.
• Grimacing of face and restlessness: Infants with tetanus neonatorum may exhibit grimacing or facial spasms, as well as restlessness and agitation.

These symptoms usually appear from 4 to 14 days after birth, averaging about 7 days [3][13]. If left untreated, tetanus neonatorum can have a poor prognosis, with a fatality rate of up to 100% [10].

Diagnostic Tests for Tetanus Neonatorum

Tetanus neonatorum, also known as neonatal tetanus, is a form of generalized tetanus that occurs in newborn infants. Since there are no specific laboratory tests to diagnose tetanus neonatorum, the diagnosis is primarily based on clinical evaluation and symptoms.

• Clinical Examination: A thorough physical examination by a healthcare provider is essential to diagnose tetanus neonatorum. The provider will look for classic signs such as muscle stiffness and spasms in newborns with a history of unsanitary birth conditions [13].
• Lumbar Puncture: In some cases, a lumbar puncture may be performed to rule out meningitis or other central nervous system infections that can present similarly to tetanus neonatorum [9][10].
• Electroencephalogram (EEG) and Electromyography (EMG): These tests may also be used to rule out other conditions such as seizures or muscle disorders, but they are not specific for diagnosing tetanus neonatorum [10].

It's essential to note that the diagnosis of tetanus neonatorum is primarily clinical, and laboratory tests are not routinely available. A healthcare provider will look for a combination of symptoms, history, and physical examination findings to make a diagnosis.

Treatment Options for Tetanus Neonatorum

Tetanus neonatorum, also known as neonatal tetanus, is a life-threatening disease caused by the bacterium Clostridium tetani. The treatment of tetanus neonatorum involves both supportive care and specific medications to manage symptoms and prevent complications.

• Supportive Care: This includes providing respiratory support, wound debridement, and maintaining hydration and electrolyte balance.
• Medications:
  • Benzodiazepines: Diazepam is the most frequently studied and used drug for treating muscle spasms associated with tetanus. Lorazepam is another effective alternative (1).
  • Antibiotics: Metronidazole is the most appropriate antibiotic, while parenteral penicillin G is an alternative treatment (9). The antibiotics are used to treat the underlying bacterial infection.
  • Human Tetanus Immunoglobulin (TIG): This is a human antibody that can neutralize the tetanospasmin toxin. It should be administered without delay (8).
• Other Medications: Sedatives like phenobarbital may also be used to control muscle spasms, and antibiotics like doxycycline or penicillin G may be used to treat the underlying bacterial infection.

Important Consideration

It is essential to note that tetanus neonatorum requires immediate medical attention. The treatment should be initiated promptly, and the patient should be hospitalized in a quiet environment to prevent further complications (9).

The differential diagnosis of tetanus neonatorum, also known as neonatal tetanus, includes several conditions that can mimic the symptoms of tetanus in newborns.

• Birth Asphyxia: This condition can cause similar symptoms to tetanus neonatorum, including failure to feed, vomiting, and convulsions [7].
• Hypoglycemia: Low blood sugar levels can also present with similar symptoms, such as seizures and muscle spasms [4].
• Hypocalcemic Tetany: This condition is characterized by muscle spasms and tetany (a condition where the muscles contract involuntarily) due to low calcium levels in the blood [5].
• Seizures: Neonatal tetanus can sometimes be confused with seizures, which are a common cause of neonatal mortality [13].
• Meningitis: This infection can also present with symptoms similar to tetanus neonatorum, such as convulsions and muscle spasms [6].
• Sepsis: Infection in the blood can also mimic the symptoms of tetanus neonatorum, including failure to feed and vomiting [13].

It's worth noting that the diagnosis of tetanus neonatorum is primarily clinical, with no specific laboratory test available. However, a positive wound culture and isolation of the organism can confirm the diagnosis in some cases [11].
