Why is LP contraindicated in thrombocytopenia?
Spinal haematoma Performing an LP or administration of epidural anaesthesia is a relative contraindication in people with thrombocytopenia due to this perceived higher risk of complications (van Veen 2010).
What are the contraindication of lumbar puncture?
Absolute contraindications for performing a LP include infected skin over the puncture site, increased intracranial pressure (ICP) from any space-occupying lesion (mass, abscess), and trauma or mass to lumbar vertebrae.
Why is lumbar puncture contraindicated in increased ICP?
Increased intracranial pressure (pressure in the skull) is a contraindication, due to risk of brain matter being compressed and pushed toward the spine. Sometimes, lumbar puncture cannot be performed safely (for example due to a severe bleeding tendency).
Is Plavix a contraindication to lumbar puncture?
Aspirin or clopidogrel, or both, did not meaningfully increase hemorrhagic complications in patients undergoing lumbar punctures, regardless of when the antiplatelet drug was discontinued relative to the time of the procedure.
Is anticoagulation a contraindication to lumbar puncture?
Lumbar Puncture is relatively contraindicated in patients with INR > 1.4 due to concern for iatrogenic spinal hematoma leading to possibly irreversible neurologic injury. Therefore, all patients who are therapeutically anticoagulated with Warfarin (INR >2.0) are at increased risk.
When should you not do lumbar puncture?
Absolute contraindications for lumbar puncture are the presence of infected skin over the needle entry site and the presence of unequal pressures between the supratentorial and infratentorial compartments.
In which condition is lumbar puncture not helpful in diagnosis?
Severe thrombocytopenia, bleeding diathesis or anticoagulant therapy are contraindications to Lumbar Puncture, although it can be performed safely at platelet counts of 50 x 109/l or above.
How is the risk for complications of lumbar puncture reduced?
Before performing the lumbar puncture, ensure that patients are hydrated so as to avoid a dry tap. Never allow a lumbar puncture or a pre–lumbar puncture CT scan to delay administration of intravenous (IV) antibiotics; meningitis can usually be inferred from the cell count, antigen detection, or both.
Is hydrocephalus a contraindication to lumbar puncture?
Suspected increased intracranial pressure (ICP) due to an intracranial mass lesion, cerebral edema, or obstructive hydrocephalus is a relative contraindication to performance of an LP and also requires independent assessment and treatment.
