What are the concerns for hemodynamic stability in a patient with an extradural hematoma, non-Hodgkin's lymphoma, recent chemotherapy, febrile neutropenia, and potential coagulopathy due to thrombocytopenia, Disseminated Intravascular Coagulation (DIC), or hepatic dysfunction?

From the Guidelines

The management of extradural hematoma in patients with non-Hodgkin's lymphoma, recent chemotherapy, and febrile neutropenia requires urgent coagulation studies and correction of coagulopathy before neurosurgical intervention, with a focus on maintaining platelet counts above 50,000/μL and correcting INR with fresh frozen plasma and vitamin K as needed, as suggested by the 2020 ACC expert consensus decision pathway on management of bleeding in patients on oral anticoagulants 1.

Key Considerations

• Urgent coagulation studies, including platelet count, PT/INR, aPTT, and fibrinogen levels, should be obtained immediately to assess the severity of coagulopathy.
• Coagulopathy correction is essential before neurosurgical intervention to minimize the risk of bleeding complications.
• Platelet transfusions should be administered to maintain counts above 50,000/μL for minor procedures and above 100,000/μL for major neurosurgical interventions, as recommended by the management of cancer-associated disseminated intravascular coagulation guidance 1.
• Fresh frozen plasma (10-15 mL/kg) should be administered for elevated INR, while cryoprecipitate is indicated for fibrinogen levels below 100 mg/dL.
• Vitamin K (10 mg IV) is appropriate if warfarin effect is suspected, as suggested by the 2020 ACC expert consensus decision pathway on management of bleeding in patients on oral anticoagulants 1.

Additional Measures

• Chemotherapy-induced thrombocytopenia and neutropenia-associated sepsis can worsen coagulopathy, requiring broad-spectrum antibiotics alongside coagulation management.
• Intracranial pressure monitoring and management with mannitol (0.25-1 g/kg IV) or hypertonic saline (3% solution) may be necessary while preparing for surgery, as recommended by the management of severe traumatic brain injury guidance 1.
• The decision for neurosurgical evacuation must balance the risk of hematoma expansion against bleeding complications, with some patients benefiting from medical management of ICP until coagulopathy is corrected.

Prioritizing Morbidity, Mortality, and Quality of Life

• The primary goal is to minimize morbidity and mortality while optimizing quality of life for patients with extradural hematoma and coagulopathy.
• A multidisciplinary approach, involving neurosurgery, hematology, and critical care, is essential to ensure comprehensive management of these complex patients.

From the Research

Haemodynamic Stability in Extradural Hematoma

• Haemodynamic stability is crucial in patients with extradural hematoma, especially in the context of non-Hodgkins lymphoma, recent chemotherapy, and febrile neutropenia, as it raises concern for coagulopathy and hemodynamic instability 2.
• Contributing factors to haemodynamic instability may include thrombocytopenia, DIC, or hepatic dysfunction, emphasizing the need for urgent coagulation studies and correction as needed 3.
• Vitamin K may be appropriate if anticoagulant use is suspected, and neurosurgical intervention must be balanced against bleeding risk and cardiovascular instability 3.

Management of Extradural Hematoma

• The management of extradural hematoma depends on various factors, including the volume of the hematoma, the patient's Glasgow Coma Scale (GCS) score, and the presence of other injuries 4, 2.
• Non-operative management may be considered for patients with small hematomas (<30 cm3) and a stable GCS score, while surgical evacuation is often necessary for larger hematomas or those with significant mass effect 5, 4.
• The decision to operate or not should be based on individual patient factors, including the risk of bleeding and cardiovascular instability, and should be made in consultation with a neurosurgeon 5, 6.

Predictive Factors for Regression or Progression

• Predictive factors for regression or progression of nonevacuated posttraumatic acute extradural hematoma include the patient's age, GCS score, location of the hematoma, and presence of coagulopathy 6.
• Patients with higher GCS scores, frontal location of the hematoma, and associated fissure fracture are at low risk for progression, while younger patients, those with persistent nausea/vomiting, early CT scan, temporal hematomas, or coagulopathy are at higher risk 6.
• Close observation and serial CT scans are necessary to confirm regression or detect early progression of the hematoma 6.
