Dysautonomia: perioperative implications

Area of Science:

• Neurology
• Cardiology
• Anesthesiology

Background:

• Severe autonomic failure affects approximately 1 in 1,000 individuals.
• Patients exhibit paradoxical physiological and pharmacological responses.
• Commonly noted symptoms include orthostatic hypotension, but also supine hypertension, altered drug sensitivity, and blood pressure changes with ventilation.

Purpose of the Study:

• To review the clinical pathophysiology of autonomic failure.
• To emphasize aspects relevant to perioperative care.
• To discuss diagnostic and treatment strategies for patients with autonomic failure.

Main Methods:

• Literature review focusing on autonomic failure pathophysiology.
• Analysis of clinical manifestations and patient responses.
• Examination of perioperative management strategies.

Main Results:

• Autonomic failure presents with diverse and complex symptoms beyond orthostatic hypotension.
• Patients demonstrate heightened sensitivity to various stimuli and medications.
• Effective perioperative management requires a thorough understanding of the condition's pathophysiology.

Conclusions:

• Autonomic failure necessitates specialized care, particularly in the perioperative setting.
• Comprehensive diagnostic and treatment approaches are vital for patient safety.
• Optimized preoperative, intraoperative, and postoperative care improves outcomes for patients with autonomic failure.
