Lumbar drains: Practical understanding and application for the otolaryngologist

Area of Science:

• Neurosurgery
• Otolaryngology
• Nephrology

Background:

• Lumbar drains are frequently employed in otolaryngology for managing cerebrospinal fluid (CSF) pressure.
• Their primary applications include treating CSF leaks from fistulas or post-skull base surgery to promote healing.

Purpose of the Study:

• To highlight the importance of otolaryngologists understanding lumbar drain management.
• To emphasize the need for familiarity with potential complications and monitoring.

Main Methods:

• Insertion of lumbar drains into the intrathecal space.
• Routine neurologic examinations, monitoring for infection, and assessment of CSF drainage rates.
• Adherence to a maximum 5-day duration to minimize infectious risks.

Main Results:

• Complications, though infrequent, can occur and may necessitate drain adjustment or removal.
• Potential adverse events range from headaches and cranial neuropathies to severe outcomes like intracranial hemorrhage.
• Close monitoring for fever, nuchal rigidity, and neurological changes is essential.

Conclusions:

• Lumbar drains are vital tools in otolaryngologic patient management.
• Otolaryngologists must be knowledgeable about lumbar drain function and potential adverse effects for timely intervention.
