Adrenergic hyperactivity and epidural block in severe tetanus. A case report.

Area of Science:

• Anesthesiology
• Neurology
• Critical Care Medicine

Background:

• Tetanus can cause severe sympatho-adrenal overactivity, leading to dangerous cardiovascular disturbances.
• Management of these autonomic symptoms in tetanus is crucial for patient outcomes.

Observation:

• A 69-year-old male patient presented with severe tetanus and significant sympatho-adrenal overactivity.
• Cardiovascular instability and elevated plasma catecholamines were noted.

Findings:

• A lumbar epidural block was administered to manage the sympatho-adrenal overactivity.
• The epidural block successfully reduced cardiovascular disturbances and decreased plasma catecholamine levels.
• However, the duration of other tetanus manifestations remained unaffected by the intervention.

Implications:

• Lumbar epidural blocks represent a potential therapeutic option for managing autonomic dysfunction in severe tetanus.
• This intervention may help stabilize hemodynamics and mitigate risks associated with catecholamine excess.
• Further research is needed to explore the broader efficacy and limitations of epidural blocks in tetanus management.
