[Cerebrospinal fluid shunting: anesthetic particularities]

Area of Science:

• Neurosurgery
• Anesthesiology

Context:

• Hydrocephalus treatment necessitates cerebrospinal fluid (CSF) drainage via external or internal shunts, or endoscopic ventriculocisternostomy.
• Anesthetic management varies based on patient age, with local anesthesia suitable for external drainage in older children and adults, while general anesthesia is required for others.
• Increased intracranial pressure presents challenges like difficult intubation and a full stomach, demanding anesthetic approaches that prioritize homeostasis.

Purpose:

• To outline anesthetic considerations for patients undergoing cerebrospinal fluid (CSF) drainage procedures for hydrocephalus.
• To highlight potential complications and management strategies for patients with CSF shunts, particularly in specific physiological or procedural contexts.

Summary:

• Cerebrospinal fluid (CSF) drainage techniques for hydrocephalus include external drainage, internal shunting, and endoscopic ventriculocisternostomy.
• Anesthetic drug selection should avoid ketamine and enflurane, with anti-epileptic drugs being mandatory and antibiotic prophylaxis recommended for internal drainage.
• Complications such as infections, mechanical failures, and bleeding are common, leading to reinterventions and repeated anesthesia exposure.

Impact:

• Patients with shunts face risks of malfunction during pregnancy, MRI, or laparoscopy, requiring neurosurgical team collaboration and shunt function verification.
• Effective anesthetic management and prompt recognition of shunt-related issues are vital for patient outcomes and minimizing the need for iterative procedures.
• Understanding these anesthetic challenges and shunt-related risks is crucial for optimizing patient care and managing hydrocephalus effectively.
