Abstract

Insights

New oral anticoagulants (NOACs) simplify perioperative management but require careful consideration of renal function and procedure timing. Currently, no antidotes exist for NOACs, necessitating informed clinical decisions for bleeding risk assessment.

Area of Science:

  • Pharmacology and Therapeutics
  • Cardiology
  • Anesthesiology

Background:

  • New oral anticoagulants (NOACs) are emerging as alternatives to warfarin for stroke prevention in atrial fibrillation.
  • Optimal perioperative management of patients on NOACs is crucial due to their anticipated widespread future use.

Purpose of the Study:

  • To review evidence-based guidance for perioperative use of NOACs.
  • To inform optimal patient care during surgical procedures.

Main Methods:

  • Systematic literature search of PubMed for articles on NOACs in the perioperative period (January 2000 - January 2014).
  • Focus on evidence-based guidance for managing NOACs around surgery.

Main Results:

  • NOACs (e.g., rivaroxaban, apixaban, dabigatran) offer simplified perioperative management due to rapid onset and predictable pharmacokinetics.
  • Challenges include lack of routine monitoring (INR) and available antidotes.
  • Discontinuation timing depends on renal function and procedure type; guidelines for bleeding management are provided.

Conclusions:

  • Effective perioperative NOAC management requires understanding drug intake timing, renal function, and procedure risks.
  • Currently, no specific antidotes exist to reverse NOAC effects, emphasizing the need for careful clinical assessment.

Anticoagulant 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...

Anticoagulant 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...
