Summary
Patients on anticoagulation therapy face risks with epidural or subarachnoidal procedures. Careful timing of regional anesthesia and heparin administration is crucial to prevent spinal hematoma.
Area of Science:
- Anesthesiology
- Neurosurgery
- Hematology
Background:
- Neuraxial anesthesia carries a risk of spinal hematoma in anticoagulated patients.
- Combining anticoagulants with neuraxial techniques requires careful management.
Purpose of the Study:
- To outline safe protocols for neuraxial anesthesia in patients receiving anticoagulants.
- To define time intervals and conditions for safe central neural blockade with heparin therapy.
Main Methods:
- Review of existing literature and clinical guidelines on anticoagulation and neuraxial anesthesia.
- Analysis of risks associated with different anticoagulants and anesthetic techniques.
Main Results:
- Isolated aspirin or NSAIDs are generally safe.
- Combined heparin therapy (unfractionated or low-molecular-weight) with neuraxial blocks requires strict adherence to timing protocols.
- Safe procedures involve specific time intervals between anticoagulation and block placement/catheter removal.
Conclusions:
- Neuraxial anesthesia can be safely performed in anticoagulated patients by respecting minimum time intervals.
- Careful management of heparin therapy and catheter removal is essential to prevent vertebral canal hematoma.

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:30Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
01:18Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:19Depolarizing Blockers: Pharmocokinetics
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
