Neurological infections after neuraxial anesthesia

Area of Science:

• Neurology
• Infectious Diseases
• Anesthesiology

Background:

• Infection represents the most frequent cause of severe neurological complications after neuraxial anesthesia.
• The occurrence of these infections is influenced by the expertise of the practitioner and patient demographics.

Purpose of the Study:

• To review the common causes, risk factors, and preventive strategies for infectious complications associated with neuraxial anesthesia.

Main Methods:

• Literature review focusing on meningitis and epidural abscess following neuraxial anesthesia.
• Analysis of risk factors including operator technique, patient conditions, and procedural elements.
• Identification of established and recommended preventive measures.

Main Results:

• Meningitis, often caused by viridans streptococci, is linked to dural puncture during labor, inadequate aseptic technique, and concurrent infections.
• Epidural abscesses, typically caused by Staphylococcus, arise from catheterization, with prolonged use, poor asepsis, and traumatic insertion as primary risks.
• Preventive strategies encompass mask usage, rigorous sterile techniques, limiting catheter duration, and judicious antibiotic use in high-risk cases.

Conclusions:

• Implementing strict aseptic protocols and optimizing neuraxial anesthesia procedures can significantly reduce the incidence of serious infectious complications.
• Adherence to guidelines for catheter management and operator technique is crucial for patient safety.
