What are the post-craniotomy care guidelines for inpatients?

Post-Craniotomy Care Guidelines for Inpatients

Post-craniotomy care should focus on close neurological monitoring, management of intracranial pressure, prevention of complications, and early intervention for any deterioration to optimize patient outcomes in terms of mortality and morbidity. 1, 2

Immediate Postoperative Monitoring

• Transfer patients to a neurointensive care unit or specialized stroke unit for close and frequent monitoring of neurological status 3, 1
• Monitor level of consciousness (e.g., using Glasgow Coma Scale or Canadian Neurological Scale) at least hourly, with more frequent assessments as the individual patient condition requires 3
• Assess for worsening symptom severity and monitor blood pressure at least hourly 3
• Immediately notify the neurosurgical team if changes in neurological status occur, including decreased level of consciousness, changes in CNS score by ≥1 point, or change in NIHSS score by ≥4 points 3
• Obtain repeat CT scans when deterioration in neurological status occurs 3, 4

Management of Intracranial Pressure

• Maintain cerebral perfusion pressure (CPP) >60 mmHg using volume replacement and/or catecholamines if necessary 3
• For patients with suspected elevation in intracranial pressure, follow institutional protocols for management, which may include:
  • Administration of hyperosmolar therapy (mannitol 20% or hypertonic saline) 3, 2
  • Head of bed elevation between 0-30° 3
  • Target serum osmolality of 300-310 mOsmol/kg 3, 2
• For severe cases, consider profound sedation, analgesia, intubation, and controlled mechanical ventilation with target PaCO₂ of 35 mmHg 3

Prevention and Management of Common Complications

Neurological Complications (occurring in approximately 16% of patients) 5

• Monitor for focal neurological deficits, which may occur even without radiographic correlates 6
• Watch for seizures, which occur in approximately 8% of postoperative patients 7
• Consider prophylactic antiepileptic therapy, particularly for patients with multilobar involvement 7
• Monitor for hyponatremia, which can present with depressed mental status or even focal neurological deficits such as pupillary changes 6

Non-Neurological Complications

• Manage postoperative nausea and vomiting (PONV), which occurs in approximately 25% of patients 5, 3
  • Use multimodal antiemetic regimens targeting different chemoreceptors 3
  • Consider serotonin 5-HT3 receptor antagonists (e.g., ondansetron) and steroids (e.g., dexamethasone) 3
  • Avoid medications that can cause confusion or sedation (e.g., anticholinergics, phenothiazines) at higher doses as they may impair neurological examination 3

Glycemic Control

• Maintain strict perioperative glycemic control as poor control has been associated with increased risk of poor clinical outcomes 3
• Prevent both intraoperative hyperglycemia and hypoglycemia 3

Management of Coagulation Disorders

• Correct coagulation disorders before craniotomy according to their etiology, potentially in collaboration with a hematologist 3
• For patients on anticoagulants who underwent emergency procedures:
  • Use protamine sulfate to reverse heparin-associated ICH 3
  • Administer intravenous vitamin K to reverse warfarin effects 3
  • Consider prothrombin complex concentrate, factor IX complex concentrate, or FFP for rapid INR normalization 3

Special Considerations for Decompressive Craniectomy

• For patients who underwent decompressive craniectomy, monitor for specific complications including:
  • Extracranial herniation 4, 8
  • External brain tamponade 4, 8
  • Paradoxical herniation 4, 8
  • Trephine syndrome 4

Planning for Cranioplasty

• Perform comprehensive neurosurgical evaluation to confirm readiness for cranioplasty 1, 2
• Obtain CT imaging to assess for decreased vasogenic edema, which indicates appropriate timing for reconstruction 1, 2
• Consider timing carefully, as early cranioplasty (within 10 weeks) may have higher complication rates, particularly in patients with ventriculoperitoneal shunts 2
• Be aware that delaying bone flap replacement may lead to development of communicating hydrocephalus 2

When to Escalate Care

• Immediately notify the neurosurgical team for:
  • New or worsening focal neurological deficits 3
  • Decreased level of consciousness 3, 6
  • Signs of increased intracranial pressure 3
  • New onset seizures 7
  • Wound complications or signs of infection 4

By following these guidelines, clinicians can optimize post-craniotomy care to improve patient outcomes while minimizing complications and mortality.
